HTC Fuze, Black/Blank Screen. Everything Else works, just can't see it. - Touch Pro, Fuze General

Firstly, my screen does not show visuals. I can still touch the screen and make things happen, but it is just a back-lighted black screen. I have answered calls on it and such. Basically I'm returning it and getting a new one.
Since I am getting a new one, I want to see if anyone ever heard of this problem and to see what the cause of it is, for prevention purposes.
I didn't get it wet (the white sticker in the back is still white.) Though I have flashed PROven ROM to it a couple months ago (it's a great ROM by the way), but could that have messed up my screen?
I also wanted to know since I can't see the screen, would I have to, for warranty purposes, (blindly) reflash to the Stock ROM?
Thanks in advance!

Yeah, you probably oughta return it to stock configuration (good luck on that!). If you're really lucky, that might even fix the problem. Have you done a hard reset yet? Might be worth a try, although it certainly sounds like a hardware problem.

Sounds like the flex cable has gone bad

Exactly same thing happened to me this Tuesday. Luckly I backed up info to memory card using PimBackupV2.8 with remote control software on my PC. With the remote contol tool, I could see everything as if on my phone and icons are clickable.
Hard reset did not fix the issue. I then flashed the shipped official ROM and stock SPL for warranty purpose. Will send the phone to them today for repair.

mine also like that..
from vodafone also..
the things that make me panics is the phone become hotter and hotter.

Summer is coming...

Sometimes they make updating phones too easy......

The back of my phone often gets hot I have to use the edges to hold it even though it was not a hot day and it is in my pocket.

blank screen
ya so my screen is blank white
but everything else works
i've heard something about this being a faulty "flex cable"
how can i fix this?
thanks so much for your help

how do i fix this???

did you eventually find out how to fix this/???

u ever end up fixing that? how?
thankss

Mine was still in warranty so I rang Vodafone. They sent me a special delivery envelop the following day. I sent it back to them. The following day I got a text message from them saying they got it and was working on it to fix the fault. The next day received another message saying the device was on the way back to me and I should receive it the following day.
Actually they sent me back a replacement

So.. basically.. is this a faulty flex thing?

I had the same problem for the last week until today i was about to buy another one since i dont have any warranty for this one.. I searched google and saw somebody say that just putting a business card between the keyboard and the lcd and then slide it and it works so far
hope it helps everybody

Ack! my Fuze, which I got off eBay a few months back, just went black too.
I'm not exactly sure whether it's the LCD or the flex cable, but the fact that the D-pad backlight also has become intermittent makes me think it's the cable.
So has anyone attempted the flex cable repair themselves? I see you can buy the cable for around $40 and the LCD for around $80 from Hong Kong.
Maybe this is a sign I should just get an Android device.

same thing happened to me Twice.... in my sleep overnight. I LOOOOOOOOVe my raphael but man this was the last straw

This maybe of some help for those of you with blank screens. I bought a Touch Pro on ebay that had a very dark screen, occasionally you could just make out some icons being displayed. Using Mymobiler showed that the basic system was working, as was the touchscreen. Other symptoms were that the camera would not work and the keypad lighting was intermittent. Sometimes on connection to Mymobiler a dialog box would come up saying there was an error with Microp?!?
Despite cleaning all internal connections and ensuring they were correctly and securely made the problem remained. I then noticed that the small camera used for video calls (in a socket on the main flex cable) looked very dirty and corroded. I removed the camera module and, using a fibreglass brush, cleaned the contacts on both the socket and the camera module. These were very badly corroded with verdigris.
On putting everything back together I was most surprised to find the screen was now working, as was the main camera. Unfortunately the ROM that is loaded doesn't seem to have any facility for checking the front video camera. There are still problems with sound - both the loudspeaker and the headphones seem to be dead and I have not had the opportunity to test GPS, Wifi, bluetooth, buttons, etc, however I will keep working on it.
Hope this is of help to someone.

Att Fuze black screen need help please! Not a bad flash issue.

Hi all,
I am at my wits end on this problem if anyone can offer any adivice it would be greatly appreciated. So let me give a recap of what has occured thus far. The water damage tag for some reason turn pink thus i am unable to get warranty exchange. I am pretty certain that the phone has never been expose to any water of anything of that sort, but i do live in houston, tx so might be humidity or what not that cause the tag to turn. Anyways.
1. This all started after i flashed RRE 5.2 RC3. Initially after a successful flash everything seem normal and fine. Then next morning i woke up to a frozen screen with many verticial lines running up and down the screen was almost unreadable. Initially i thought it was a bad flash or just random lock up. I did a hard reset and tried to enter the bootloader. Black screen, it does seem like the backlight is coming up but nothing on the screen. I can hear the phone power on and boot successfully into windows. Activesync connects i can browse the contents of the phone.
2. After flashing to stock att rom and stock htc roms same symptoms. So at this point i am thinking crap bad LCD screen. so I ordered both the digitizer and lcd screen for good measure. I replaced them hoping that a bad LCD was all. replaced both screens and i powered on the phone. same problem. black screen. The phone still powers on and boots into windows. Activesync still connects and i cna still reflash the phone.
3. I work extensively and do both desktop pc and notebook repair. I am not new to dealing with small electronic repairs. but at this juncture i am unable to identify the cause of hte malfunction. i am hoping maybe some of the gurus here might be able to shine some light on the subject.
Thanks in advance for any help.
I would have followed the same approach; your description makes it sound like it might be some kind of backlighting issue at first read. I'm inclined to think it might be a cold connection (bad connector) on the main board.
Silly question, what happens if you power up the phone with the keyboard exposed?
*EDIT* Not sure if you have been here yet: http://www.mikechannon.net/
Cheers,
i just tried to power up the phone with keyboard exposed. Powers up the same as with the keyboard hidden. Still boots up fine but black screen. I already have the service manuel dowloaded. i have checked around with several repair places both local and on the web. Seems like no one has any parts for the att fuze/touch pro gsm except for the lcd and digitizer and a speaker.
its quite possible that it is a main board but as the same time it might be something as simple as a ribbon cable. i have contacted htc about doing a possible repair and they want wayyyy too much for just a main board repair almost $400 USD.
Anyone have a bricked/ non working touch pro they would like to sell ? =P

Could be a bad ribbon cable ... and firmly pressing around the front/back of the unit shows no change?
pressing the phone front and back show no changes to display. in a very dark room I can see that there is light emitting from the display but its just the screen is not displaying anything visable. this occured both before and after i changed out the screens. I'll do another visual inspection of all the boards to see if there is any bad resistors burnt out circuits etc.. but i didn't notice anything mentionable during my first 2 inspections. Maybe 3rd time is the charm.
Thanks for all the feedback thus far Hilaireg it is quite appreciated. All this venting has at least made me feel 1000% better than after i replaced my lcd and still same problem at least i don't feel like a complete idiot!
Sorry I couldn't be of much help ... you've done all the steps a seasoned hardware person would do.
Do post back to let other folks know if you get it back up and running.
Cheers,
you have a pm fkoong.
I have possibly the same problem. Phone got wet, dried it out for 2 days (in a container of rice). Phone worked but had "water marks" on screen that disappeared after two days and everything was fine for about 2 weeks. Then one day (happened to be humid misting rain eve in Charleston) the screen is blank (hint of backlight only). A soft reset and it seems OK for about 1hr, then blank again. The hard resest screen displayed OK (readbale text etc), but didnt work. But as I write this, I retry to document it results correctly and the NATF ROM is reloading and the screen works! We will see how long!!
Well.. not that long, the end of the ROM load and it went blank again, seems like a video driver problem. The Press VoluP to boot does show some red artifact.
Trying hard reset again (No SIM no uSD)
The NATF v4.4 loads and gives me the Tap screen, Align Screen, stylus, loads customization, opera, tf3d, then loads a bunch of files under ...... and then the screen goes blank again, seem like what happened last time, so Ill try loading a fresh ROM copy... later

Diamond Screen Problem

I need to align the screen again & again can any one help me out wer the problem lies
how did this happen? i also encounter a similar problem, when the phone gets warm... when i press on the right side, the click registers mode and more to the left... and when that happend, if i try to go to the alignment screen, it just hangs in there like.. forever... if i put the phone in standby mode, everything gets back to normal in a few minutes.. the problem repeats every time the phone gets warm...
Same
First i was also having the similar problem but now its totally unaligned i.e even after a time its same i click on extreme left it click on extreme right
nasty man... dunno why this is happening... so, my screen is dying.. damn :| what kind of mods did u do to your phone? software ones
I have the same problem! Seems this is an manufacturing issue that's affecting many Diamonds! Does the warranty cover this?

YEAH! ) i sent mine to warranty today, lol 15 long days at max until it will be back in my loving arms
i dont know if this might help
i used to have flickering screen, not being able to display alpha blend, transparencies or the colour black, and also not being able to keep the screen alignment (it resets everytime i soft reset the phone) ....
this happens when i used the latest update from htc.
it seems that the upgrade is not suitable for devices bought in 2008 as it has the ols original spl.
i read in the forum and found out that the radio, and the hard spl was part of the problem. so i read on and found that by using Olipro's hard spl 1.93 will fix most of the problem. but its for only gsm devices.
i flashed 1.93 hard spl and all my problems went away...
just sharing!!
i can see some leaked fluid above my screen ........... i cannot even explain it , because it's above the screen but i cannot touch it ........ so it's in between.....
i've had the same thing happen to me and sent it in for warranty.
came back ok for awhile, now its happening again. I usually just suspend my phone (power button) and give the LCD a rub that helps it a little, buts its quite unbearable at times.
I've sent it in to warranty for a second time today, warranty is expiring on the 8th of next month so they better fix it by then .

I have the same screen align problem. When the phone gets hot, the screen alignment screw up, similar to this one:
http://www.youtube.com/watch?v=5-IUzerAT0s&feature=related
I was told this is a hw problem as I've tried flashing different ROMs, update radios etc. but still doesn't help.
Right now I'm trying to avoid using the phone when charging or when it becomes warm. That seems to help a bit. Not sure if replacing the screen will help but a few folks here have suggested that.

Long story short: it is a hardware problem! nothing you can do to fix it via software... and it gets worse, so get it fixed
I have just received mine from service a few days ago... Of course i lost my warranty and I paid almost 200$ to get it fixed... The front case gets replaced entirely (that includes both digitizer and LCD), because it comes in one piece... all components are stuck together that is, even if you have a perfectly working LCD, it will be replaced anyway... Fortunately this helped and I am not experiencing any problems... Also I've been told that this problem may occur again, after some time (1-2 years), if the phone is heavily used (gps, connected on 3G + screen awake for a long period of time), and that the simptoms may vary: some get the digitizer / misalignment problem, others get weird spots on their lcd, etc...
Hope i didn't make to many mistakes and that my reply will help you understand and get your problem solved...

I'm not too sure about that actually - how you stated the LCD / Digitizer and case comes all in one.
I've actually experienced the same issue, sent it back the first time. Fonebiz did not replace anything but a flex cable. Ironically, issue came back after a months time.
Sent it in a second time for warranty, i specifically included a note stating the issue - they replaced the LCD, but did not replace the digitizer; so guess what ? issue came back within the month.
Phone was finally out of warranty, i decided to send HTC a ***** email and they were very helpful and they've promised me a replacement. Waiting for Fonebiz to check for hardware faults if its all clear then i get a new phone

i assure you cannot replace just the lcd, not without a hammer! I got my old part back, I can take some pictures of it, just in case And the digitizer is one and the same with the front case... the diamond is a very small phone, that's why there are no screws or other stuff to hold together the lcd and the rest of the case.
So unfortunately for you, they may have told you they replaced the lcd, but i think they did nothing :|
It is very clear that we had the same problem... the digitizer itself got broken... not some cable or lcd
anyway, if your phone has warranty, you are a happy man

Water damaged Sensation

Ok, here's my problem. My sensation got water damage. I dried it. But the screen won't turn on. Backlight is not working. But when i turn the phone on it vibrates. Assuming that after the boot process i can hear the message alert like it recieved a message. Green light is also blinking. I can charge the phone. Charge light is also working. But since i can't see anything on the screen i can't be sure if evertything is working. I took the phone apart, lcd is soaked wet after all that drying. I know it because i tore the lcd apart. Anyway, my real problem is, i found a very cheap sensation with motherboard damage. I'm thinking of buying it and use my motherboard with it. But i can't be too sure if everything is alright with my motherboard. From what i can see nothing is burnt or anything on the motherboard. Since i tore the lcd apart and it's not connected, now the phone goes into bootloop from what i can tell from the vibration. And i didn't think about connecting the phone to the computer to see if it gets recognized. And now with the bootloop and everyhing plugging it to the computer is not an option anymore. What are your thoughts on this? Do you think I have a working motherboard? Do you think i should try my luck?

If you should try it depends on how much the broken phone costs. If it would cost you $200 then it's not worth it because the risk is too big.
If it would cost you $30 then it's absolutely worth a shot.
I'd say you have about a 40% chance of fixing it by combining parts from the 2 phones. So it's about how much you're willing to risk on a 40% chance.
It's gonna cost me about $100. And except the motherboard the phone is in perfect condition. Just like new. It feels like my motherboard is working fine. I mean i have all the indications that he phone is alive except the display. It charges just fine. Boots up. Even getting message indications. That's why i'm really hopeful. But of course i can't be sure 100% sure...

You're absolutely right. I replaced my screen while ago. My sensation was in a pretty bad condition. I also have to change the touch screen cuz it was popped up and part of it was unresponsive. Back cover was cracked. I also needed to replace that. My wifi was not working for a while. I believe wifi issues were software related but could never find a working solution to that. Tried every hboot, radio, rom, ruu avaliable to solve my wifi issues with no luck. It's gonna be like renewing the whole thing this way. And if I got this working, and start using it this way it's gonna give me a great satisfaction. ) I was mostly wondering if you guys think my mobo is fine...

Again....40% chance the mobo is okay.
But if its not both your current broken phone and your new broken phone have value as parts devices on ebay. So you will be able to get some money to put towards a new phone if all else fails.

From what I have gathered about motherboard issues. Once they're gone they don't even boot up. And even if they boot up mostly they won't stay on long time. Mine was on and charging for hours. Of course without the display. The guy who's selling the phone said during the update he run out of battery and phone was hard bricked. He took it to repair center and they screwed up his motherboard. That's what the second repair center told the guy anyways. His motherboard could also be fine, who knows. What I'm planning to do is, take my motherboard with me and try it on the spot before buying the phone. It would take me about 3 minutes to swap the motherboard anyways.
Just wanted to let you know that I saved my Sensation. Ordered the phone with the motherboard problem. Installed my motherboad and got it working. Thanks for your responses...

Nexus 5 Repaired at LG service Center - Software Failure?

Hey Guys,
My N5 is 18 months old and suddenly the screen went dead. I could hear things beeping with apps etc and could receive calls but the display was shot. I tried everything to reflash the phone but to no avail. I tried connecting to a PC to sideload - anything at all but no dice. The laptop could see the phone but couldnt access it via explorer or ADB or anything else.
I sent it into the LG Repair Center here in Forth Worth and i got this diagnosis: Software Failure. Out of Warranty by Date code, Receptacle / Minor problem.
It going to cost me 45.00 + tax to fix it so i said go ahead but i'm a little concerned on what the problem actually was. I'm afraid they are just gonna ultra flash it somehow and it'll be broke again in no time. THe repair warranty is only 90 days.
What do you guys think? Any experience on this issue or something similar? Should i get the phone back and shake it for something else?
Any input is greatly appreciated.
I see what you mean, it seems like you have a hardware problem not software, not sure how flashing will fix it if you cant see any images at boot,
You did tell them the screen is not responding right?.
It is worrying to see these stories about the screen just dying, mine is around that age.
The screen just stopped responding. Sometimes i would get a very faint backlight on the screen. Its like i was trying to start the car but she wouldnt turn over. I told them everything this is all they came back.
Not very happy....
I am having a similar problem. One day it shut off and it would only boot to google then go black. It wont connect to a computer or boot also it has no haptic feedback. LG said it was an LCD connector problem and said it would be $150 to fix...

Nexus 5 Audio and Black Screen Issues

Hi everyone, I'm have an issue with my Nexus 5 and hoping someone here can tell me whats going on.
It started off with the sound always cutting out, and I have to press the back part near the "S" logo for it to return.
Eventually the screen would go black but I can clearly see a back light is on. Now not only does the sound cut out, and screen goes blank.
It has become very sluggish to reboot it. I hold the power button until the phone reboots "Google" logo appears and the android animation. Now during this time the phone will be so slow to the point of being crippled out and i have to reboot it again and again until it is normal speed returns. Often it will black out during this time.
I'm just trying to understand what is failing. I tried safe-mode and it still has the issue. I cleared cache, reset the phone everything, nothing appears to fix the issue at all.
edit: I forgot to add, when I'm on YT or listening to music or browsing the web, even though the screen is blank with just the back light on, the sound is still going (when it works). I get text/call notifications still during this time.
My Phone Details.
Nexus 5
Android version, 6.0.1 (MOB30Y)
no ROOT
No replies at all, I guess I may have to garbage the phone. Idk what else to do with this device to fix it.
Please don't throw it away.
You said that pushing at a specific spot fixes the problem (or improves the audio situation). This means that it's a hardware problem. I have disassembled it many times and I know the layout. Behind the 'S' of NEXUS is actually the motherboard cover, and under it are 2 connectors; one for the battery and one for an extra 'board' that is located right underneath the LG logo on your back cover. On that 'board' is your screen connector, and also the speaker rests on there, as well as the primary microphone, 3G and 4G antennas and of course the USB port. The connector for this extra board is actually located a bit to the left on the 'S' (when you look at your phone from the back, it's more below the camera).
Now I have to note this: While using my phone, I have experienced some UI hiccups. At random times (very rarely) everything would just freeze for a few minutes, though music would still play. The power button was useless apart from the hard reset, it was so badly stuck. This was a software problem, although it appeared MOST at one point when my motherboard was faulty. Since I got a new device, it happened again but only once. I'm not sure that this is what you are experiencing. If this is the case, then it's a software fault. Never happened on CM so you can give it a try.
But since it's probably a hardware problem, you can always check it out yourself. Obviously if you have warranty you are covered. Otherwise, you can try disassembling it, at least take the back cover and the motherboard cover off, it's ridiculously easy, there is a disassembly guide from ifixit (I think) online, just be careful not to break the clips of the back cover (xp talking). If you open it, keep away metal things and the first thing you do after you remove the motherboard cover is remove the battery (xp talking again). Obviously turn off the phone properly before you attempt anything. Everything is sensitive in there so be careful. What you should look for is the long connector that connects the extra board that is located at the bottom of the phone with the motherboard. That's what you are pushing so if it's not sitting correctly, then that's your problem.
Plus, everything in there, apart from the motherboard, is cheap and can be found on eBay so don't worry if something is broken (unless it's the motherboard, then no hope ).
I hope I helped.
Firstly thanks for the reply. I did manage to remove the back and get to the connector you were saying. I reseated this and noticed the phone was working much better. I noticed the following still.
When it starts acting slow/crippled pressing this connector fixes the issue. However once the screen goes black with just a backlight this method is rendered useless. Also sometimes when I plug in the wire to charge it will cripple and or go black. So I wondering if the board is shot as you suggested to order a new one, or is it the connector strip ?
Again thank you for the response.
It seems like this board is causing everything. First, check the connector on the motherboard. Make sure that nothing is wrong on the motherboard. Then you can remove the bottom black plastic thing that has the speaker on it and 2 antennas. Then, inspect this board. Check the connector of the display. There is only one big connector on it. This board is glued on the frame of the phone. You can remove it but do it carefully. Do it slowly so that you don't break it. First, remove the antennas extension cables from either this board or the motherboard, and then pull it out.
This board is definately responsible for the black screens and audio issues (unless your display is faulty, check its connector), but I'm not sure about the phone being sluggish. Since this board offers input to the motherboard, I suppose that it could be its fault.
Remove it and inspect everything. Then, if you want, you can order a new one. If you come across D820 and D821 models, I don't think that this part of the phone has anything to do with it so don't worry.
I will take a further look into this for sure, and report back. If you can provide which motherboard is required for my device, so I can also read into this and so that I may order it right-away. Is there any model number or something that indicates which board to order once it is open?
Thanks again!

You don't need to change the motherboard, not to mention it's very expensive and hard to find. What you need to replace is probably the flex cable that goes below the battery. For example this.
This is not model specific, you can use it with all available Nexus 5 models (D820/D821, 16/32GB) so it doesn't matter what device you have.
FYI, if you think that you should replace your motherboard (you probably shouldn't), you need to take into account the storage (16/32GB) and the network differences (D820 or D821, the only difference is about the 4G networking, the american version has some bands enabled and some others disabled, and vice versa)
Okay, I just ordered the replacement flex cable. It is going to take about a month before it arrives from HK , I hope it fixes the issues. I will respond to this post once it is here and installed. Thanks again.

in the meantime, pray it isnĀ“t a motherboard issue, the conector can go bad and lose a few solder joints
I have exactly the same problem... I unmounted motherboard and clean everything but didn't help to much... did you find any solution ??
Siamer no solution just waiting for my delivery of the part. However it is getting worse with the blackscreens and crippled lag.

my is the same. sometimes is working for few hours without any problems and than starting again, on the biggining it was power button problem but not I don't even touch that button (I use vol button to turn on) and sometimes screen getting black (with backlight on) and can't do anything so have to reboot... it's so anoying! Hope that parts will fix it, please let me know if you will find some solution. Today I will open phone and clean all connections etc...
Thanks,
siamer
I believe the part may fix it. I noticed if i run my finger along the strip the phone may uncripple itself or just turn black all together. I'm hoping it fixes it. I will report asap but this HK shipping is so slow it will be a month. Also there is no tracking
ATM i'am just trying to becareful with it trying not to trigger the issue. I just did an OTA update using FlashFire (6.0.1 (MOB31E) i wish v.7 will be available for my Nexus 5 ha ha!
Also if the Nexus 7p arrives I may just buy it to replace this Nexus5.

Hi Omega59.
Today I bought air compressed can(name: air dust) and open my nexus 5 as much as I could. I clean everything, every connector, every cable etc. and last few hours is working fine... even power button is working ok. I will let you know in next few hours how it will be, hope will be still ok
Good luck!

[edit]
there is still same problem, working better than before, black screen not showing so often but still showing... I think tomorrow I will order oneplus3... Would be nice wait to see new nexus but how... :/
Yeah I'm not sure when the Nexus 7p will arrive, they not even advertised much. I will assume next year?
OnePlus 3 looks nice, but compared to Galaxy 7 it's a bit better slightly. You should check out comparison charts
Maybe they are making a OnePlus 4 soon.
oneplus 3 already ordered. I don't like samsung. I would say nexus "7p" or "pixel xl" will be launch october as always prabaly 4th of october - leaks saing that... next oneplus will be launch around july next year as I know. the only phone that I was thinking about was oneplus, htc10 or new nexus but can't wait to see nexus...
today by excident I broke screen in my nexus 5, got a little bit angry
Regards,
siamer

You probably don't want to hear this, but if it's getting worse, it's probably because of the pressure you apply to it, you make it worse. Be careful when you apply pressure around the motherboard since it's very sensitive. You REALLY don't want to break the motherboard. So if you find yourself pushing on the motherboard too often, you might want to leave it and wait for the replacement part so you won't ruin it.
Waiting for your news...
My part arrived yesterday. I put it in was pretty easy, however the first attempt i had to redo the top connector bc it was still black screen and no audio. After I disconnected the top connector ran some alcohol over it, re-put the top part things are working okay.
Just a note, the little USB connector (charger slot) seems to be very tight compared to the old one. Maybe bc it's new and not as worn down. But even just to put the wire in, requires more of a push, same with removing it.
I will see how it goes before I can really say that was the issue. I will report after a few days about it.

I don't think N7P will be out this year, they have not advertised anything and we are almost in Oct. Right now they are all rumors.

When I changed my screen and housing it was difficult to slide the USB connector in too. Just make sure that everything is in place, there is a rubber think for the microphone, maybe that's what's in the way. Don't stress the connector too much.
