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

Did my touchscreen die?

Hello everyone,
Today i installed my parrot bluetooth carkit. And after i connected a couple of times my phone became unstable.
So unstable that i'm not able to tap the screen.....
I don't know what happened due that i have hard resetted the phone a couple of times and even switched from m-rom to energyrom 3.0 with the same results.
Only one thing that was strange is that the touch pro start up screen with the red characters in the right bottom.
That after i flashed m-rom to energy rom that the touch pro characters in the middle were still different like the way that are made in m-rom. With the addition : powered by m-rom
So this means that the phone doesnt format his core
Help please give me any advice.
UPDATE:When backlight is dimmed, it will be bright if i touch it once. Afterwards it will maintain the same.
I have tried several roms and tried to restore my SPL aswell, without any results till now.
I'm getting desperate now. Due that i stays in the screen of ALLIGNMENT, so i'm really not able to start up anything from now.

Have you dropped your device recently?
Try flashing a stock/shipped rom and hard-reset when after flashing the rom when you get to the "Tap here to set up your device" screen.

I have a OIL spot in the screen when i keep it in bright light.
This could be occured when the phone was inside my bag during my beach visit.....
I guess the phone turned liquid by the sun....
Does somebody ever experienced the same issue?

I have a oil spot, and the raster of the phone with little dots in visible in the ligt.
I have made a repair order at HTC.
Which didn't satisfy me at all!
They told me that it is not covered by warranty. I was shocked, this will cost me around 70 euro to fix, and my shop warranty is still valid. So i called the shop to explain this.
And they said if this is not caused by a user, we will change the phone, but first we what to have a diagnose from HTC.
So i decided to let HTC pick up my phone . They will have a repair time of 5 up till 10 days.
That's fair, but i'm not really happy with this situation. Because i think that the screen is the most harmful component. And this means that if this part fails that my phone becomes obsolete.
I will post my conclusion after i got my phone repaired.
I will return to the STOCK spl and the original rom just for warranty purposes.

dont tell them that you spilt anything on it or dropped it. Although they will be able to tell if there is water damage to the device you might get lucky and they won't notice.
Now is the oil spot from leaving it in the sun or suntan lotion getting in the device?

Nope nothing happened at all.
Thats the strange thing about this situation.
I was in the shadow of the sun and the bags were only filled with clothes. So it didn't drop or something else.
I was able to use my phone during the day.... and was getting more unresponsive during the time that went by.
So i will not accept any blame of myself, due that i have a warranty of 1 year from the factory which will not cover your display :S
But also have the store warranty... So i told the store that i will return the phone if there are any costs.
The store told me that they will wait on the diagnose of HTC which i have sent it to myself to reduce the time.
If the diagnose tells that it's not my fault, then i can return my phone probably.... He couldn't promise it due that i want to see the diagnose first.
So I will wait on HTC's conclusion.... And i'm afraid that they will try to blame me for it....
They better not I will be a pain in there arses

Hello, I have exactly the same problem. After flashing from energyrom 3.0 to Aurora, a few hours later, i couldn't get my phone out of lock. (slide a button to the right or left on your touchscreen)
I tried a soft reset, but the phone started up with the same locked screen. So, i tried a hard reset. From that moment on i got stuck at "align screen". I ve flashed several times with several ROM's but nothing. (by the way, whatever rom i install, the first screen always says: Energyrom by NTGZ28)
I used the trick to paste welcome.not on the micro card, to bypass the align screen. That works, but the touch screen doesn't work. I 've removed the protection of the screen, but that doesn't make a difference either. My device didn't fall, came into contact with water or anything that could harm the thing. Oh, when the backlight is dimmed, the screen reacts to tapping it. Please help me out ??
resolt the issue. Because of a lot scraches (spelled ok?), i removed the protective screen. When i put the new screen on, everything worked !

Phone screen won't come on!

I'm not sure if it's lag or what, but my phone screen won't come on. I think it's a ribbon that was disconnected or something though. For about a few hours if I were to press power to see the lock screen, all I saw where a bunch of rainbow static. Then I powered my phone on and off because nothing would work and now it's jut black! Does anyone know what's wrong? I can't boot into clockwork so I don't think it's a rom problem. Does anyone know the problem or have any idea to fix? Anyone I should ask specifically?

maybe water? even having my phone in the bathroom while i take a shower cause me that

It's not water, I never bring my phone close to place with water :/

can you boot into the screen where there are 3 droids with the skateboards? (i not sure whats the name)

I think I can boot and my phone still works, because it still rings when someone calls and it still vibrates when someone text it, but I just can't pick up or reply (because the screen won't come on). I should be able to boot into that thing, but I can't anything :/

well bro sorry i cant help you :/ maybe it could be the screen,the ribons or somethings loose. did it fell?

Seems like either broken ribbon that connects the screen to the "motherboard', or dead screen itself. That's exactly how 1 of my phones died (it was too complicated to disassemble and fix it myself)
But once I had similar problem with my TP2, the screen first become unresponsive to any touch, and then it went just black after restart (and every next restart). However all keys did work.
Hard reset somewhat helped, the screen actually came back, but it was still stuck on setting up Windows Mobile (if you know WinMo: the part where you calibrate touchscreen), apparently "touch" part of the screen didn't work.
I thought it is ribbon or screen assembly, but since all the keys worked I flashed another ROM and what do you know: all problems went away. It worked fine for as long as I had it. I never figured out what caused it/was the problem.

Yea I think that's the problem here. I think I'm just going to borrow a friends mt4gs to use and navigate recovery and do a back up and just buy a new one and restore. Thanks for all the help guys

Black screen. Cant see anything but phone still works

So today my phone fell into some garbage. I dont think there was any water, but after doing some googling, it seems that is one of the causes. After i pulled the battery out, the little circle is pure white but i do see a very little spot of red. Can anyone give me any tips? If its ruined, can i easily replace it? I just got this from ausurion a few months back. I dont really want to have to shed out another 200 for another phone. I put it in rice for the time being just in case.
I can turn it on, and it vibrates normally, and it vibrates when things happen. The bottom icon lights also turn on. So, just imagine your phone working, you just cant see anything.
EDIT: Also, i cant get into fastboot, recovery, etc because it is only blank. Should i be looking into a new screen?

If there's water damage, it might be a lost cause, but if it's not, replacing the screen would be a much cheaper option than shelling out $200.

It isn't anything to do with water my phone did the same thing. You damaged the wires going to the screen. Touch still works right. Do you have insurence?

There are many different causes of problems. You can't be positive that it isn't a certain cause.

Need help with "dead" blackscreen

When I turn on phone it shows boot logo, but then black screen appears. Sound and touch work but screen is "dead" (only when system is running).

hardware problem, replacement of the motherboard or display
Is there water in the device?
if not, did you install modifications in the system (gsi, custom firmware, custom boot, etc.)?
(Google Translate Russian>>English)

Привет. No, It just suddenly went black after reboot¿. For no reason.

flash new rom if not fixed you should change your display hardware

Everyone who had this problem either got wet (the child licked the phone, etc.), or dropped it
There are a lot of such killed devices in Russia, and almost all of them had water. They were helped by the replacement of the screen

That sounds weird to replace screen if it works. Recovery, boot screen etc show up with no problem but when soft is running it turns black. I've been trying hard reset, reinstalling software etc but It doesn't work. Even guy at local repair service can't do anything about it.

only replacing the display, this is a hardware problem, it cannot be solved by software.
for those who had such a problem, only a replacement helped them (in some cases, it only helped to replace the motherboard)

me too
I have the same problem with a customer's a51, it's very strange, I did hard reset, flashed a new firmware, but when it turns on it stays on the boot logo and then when it enters the os it remains the boot logo and if I press the lock screen button remains black, I also activated the voice assistant for the blind and it actually says "screen off" "screen on" etc ...

For those who have this problem, one of my family member A51 was dropped in water and had this problem. I tested every software reset factory and reinstalling official ROM. but the screen went off but voice assistant could be heard. screen worked properly in recovery mode. I gave it to unofficial repair center. after a lot of tests they said mainboard must be changed and LCD had critical issue. both of them must be replaced. Somebody say that Samsung mobile quality is better than Xiaomi !! )
