Screen going black - HTC Vox

I've tried various different ROM images (including the excellent Dr.Gonzo), and I have this problem with all of them.
When I'm using the phone either with the keyboard in or out, the screen just switches off randomly. If I wait a few seconds (possibly the backlight timer length), then it comes back. Mostly... Othertimes I have to wait a lot longer, but it does always come back.
A reboot sometimes fixes it, but not always - does anything survive a reboot or battery removal?
Anybody else seen anything like this? I have seen a lot of threads about the screen staying on, but not off.
Of course, it could be a hardware fault, but because it's intermittent, it's hard to prove.

same problem

If you shake the phone can you re-produce this problem? I've never not heard of this being affected by software - you might also want to ensure you're not overclocking it.
Nothing is removed when you do a battery removal or reboot, ensure your connections are all tight and make sure the SIM pins are all making contact and the SIM door closes, apart from that it sounds like a possible bad LCD ribbon.

Shaking it doesn't reproduce the problem.
Once the phone has started doing this, it happens everytime you press a key.
Seems more like a memory leak to me since it always seems to happen after a while of web browsing/email use.

So actually, it looks like it might be a hardware fault.
I think it happens when the device gets warm. After a few minutes with the screen on, keyboard lit up, wifi on, the phone gets pretty warm and that's when the screen seems to go black. Leave to cool and all returns to normal.

Same issue here, but the screen does not acually go black/blank it just seems that the screen backlight does not turn back on from a standby like state, the phone itself functions but just not able to see whats going on on the screen.
(keyboard lights work fine and come on when expected)
Not sure about the heat theory as it happens (to me) most often right after a call, anything over 30-50 seconds and the backlight problem occurs, when it decides to work again is a matter of luck.
As said before because it's intermittent, it's very hard to prove.
Has anyone who has had this issue, fixed it with a hard reset ?
Very strange ... but also getting very annoying now!

i got the same thing. took it back to warranty and they said nothing's wrong with the phone but i still get this.

I experience the same problems.. it happens pretty random, but every time when you hit a key. I have set all timers to never but the problem is still there.
Running Gonzo 1.1 at the moment, upgraded from guava.. but that didn't solve the problem.
It is getting so annoying now that I am about to throw the s710 in the dustbin

I have had the same problem!
I have turn it back to my provider and no problem now.

i have the same problem with my VOX
apparently, i can still receive phone calls, and do whatever i want with the phone,
but the screen just stays black, its like if you have unplugged your monitor
since i dont have a htc center in my town or anywhere else nearby.
does anyone know a way on how to open the phone, change what need to be changed and correct the problem? im all up for testing if that would resolve this annoying problem :s
cheers everyone

there is a dismantling manual somewhere in this forum. search.
i don't think taking it apart would help you because this is not a physical fault that you can locate.
and i learned that mcel is the retail seller of vox in mozambique. they should be able to help you with service. else just send a mail to htc support and they will guide you.

yes, mcel are the retail sellers, but i tried to go there, and there are no specialists on htc's there,
the thing is, i didnt bought my htc from them, so i can't go there and change for another one
but tks anyway

no problem
but do try to contact htc support by email. they might suggest a way.

I'm having exactly the same weird problem and I think I found some pattern when it occurs. Well, the thing is that in the bright day or in a room with lots of light it works just fine. In the darker conditions… well… not so fine. It seems to me that this screen blackout happens whenever the keyboard light is on and screen changes to full brightness (in the dark, because of the light sensor). In the daylight, keyboard light doesn't turn itself on, so s710 works. I don't know much but this definitely isn't some bad contact problem. Maybe some battery problem, but I doubt it since I can receive phone call in this condition. This started to happen after I flashed this Windows Mobile 6.1 ROM from HTC (I have original S710). Flashing Dr.Gonzo's later on didn't bring any luck either. I believe that some power control SW is the main culprit. I've read that many people mention some Tornado Power Control app. Does anybody know can this application be permanently disabled or removed?

are you trying to say that by desabling the light sensor, the problem might go away?
i would also like to know if it possible to have the baklight on the lowest possible brightness forever, because it seems, on a low brightness the problem might go away

I also have this problem with the lightsensor turned off. And also at (as it seems) random moments.

well, even with the light sensor turned off, the problem persisted.
i got my phone to a repair shop of htc's, and they figured out the problem
my phone is now 100% thankfully, the repair man told that the problem was because of bad or malfunctioned circuits, he exchanged them with new ones, and the problem went away,
dont know wich circuits exactly, and he didnt want to tell me, but i suggest anyone having the same problem to try and do the same
probably its a hardware malfunction with these VOX,
its possible since so many times before i've heard about malfunctioned pieces coming out in large quantities for sale.
anyways, cheers everyone, and good luck Portugal in EURO!

I have the same problem. I just noticed that it usually happens when the phone is warm, so if you need to do something on my phone just... take some ice from fridge and put it on back of your mobile. I cant see any more solutions.
Please someone help us!

Update. Problem Solved
Just thought I'd update this thread I started.
I sent the phone back to my dealer (Grapevine in Poole,UK).
A week later, I got a brand new one back from the HTC repair centre.
So far, so good. Looks like the problem's solved.
Mike

Sam problem here,
i called with HTC and they sent them to there repair centre.

Not happy with my Raphael

I am sorry to say, but I am not happy with my new phone !
Some serious problems with it.
1. sometimes when I push the powerbutton nothing hapens, and actualy I can see the phone is fuctioning (round button is flashing for new mail). After a few seconds I get the "famous" grey screen. Reboot is the only option.
2. sometimes I wake up and the phone has boot (I guess) somewhere in the night, because I have to give my accescode for the sim.
3. the "broken glass" isue is a problem and happens twice now
Think these are not small problems for a "Pro" phone.
Right now I don't have a riable and solid phone, and I think a pro phone should be that way .
Hope this things are fixed soon.
I wonder if this is a difference in roms or if you should return your touch pro. I've beating the hell out of my phone software wise to see how it will run and i haven't had a single problem yet. I haven't been charging it via the wall charger so maybe that has something to do with it but i doubt it.
Send it back! At least try that once, if you get the same problem again then either you are very unlucky, or there is a problem with all batches. I haven't had either of those problems once and got the phone the day it came out.
I only see one or two people complaining about these issues.

I am thinking about it, to send it back. But I still hope it is a rom problem, like Bxsteeze said. Flashing another rom could help. Soon that is possible I will try.
If it doesn't help I send it back.(forgive my my English )
TBH i would do it the other way around. If flashing the ROM doesn't help because of a hardware fault and you have flashed another ROM, chances are you may not get the replacement you want.
especially as Olinex haven't finished the SPL Downgrader yet.....
DONT send it back ffs!!
We have just got HardSPL for the thing so you can actually try any ROM you wish, surely its worth the little hassle trying that first?!
I had the same "broken glass" like screen issue only once also when sitting overnight, but it wasn´t charging at all.
I have several other issue´s but it think it´s ROM related, and if it´s not i´m gonna send mine back aswel.
I've had issues 2 and 3 happen to me.
A couple of times now when trying to wake the device from an overnight charge in the morning I get no response, device locked. Soft reset and all is well.
Regarding the broken glass thing, that's definitely a software issue. Its TF3D having a spaz. If you disable it and then re-enable it, all is well.

Problems
Hi,
Four problems i found so far.
First the broken glass effect. When the phone is ringing and i turn it on his screen the ringing stops and the 3dflo breaks. Or the screen turns grey.
Problem 2 After it restarts i get an device.exe issue.
Problem 3 volume of normal calling is very low. In a noisy room it is hard to understand the caller.
Problem 4 During a call several hick-ups. Also when the signal strength is max.
For know. It is a nice smartphone but some things need improvement.
Can I remind people there is an issues thread here:

And dont forget to add the info to the wiki.
My Touch Pro has had the 'wake up' problem (either refuses to without soft reset or shows me frizzed up screen), has frozen on me during basic setup (following a hard reset) and has given me several spontaneous resets.
It also keeps forgetting my wi-fi network exists.
I feel safe in saying that I have a faulty one, so I'm asking for a replacement.

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

LCD Screen Defect or Software/Driver Problem?

Hey guys,
I am going crazy here, searching forums did not help me at all.
The lower section of the screen keeps flicking, and not always, what do i mean by flicking, its like the screen at the lower section keeps doing like a strange low refresh rate, and has an old imprint of some old menus. Happens especially when there is the color of gray.
Made a screenshot of the phone, no problems, there, so its not a software rendering problem, might be a drivers problem though, or a defec tin the screen itself.
Frequency is high but not always, and am unable to determine when does that happen exactly. going crazy here, is this a defect? or all touch pro's have this?
Exact explanation summary:
1CM from the bottom of the LCD sometimes flickers as if that 1CM is having an extremely low refresh rate. Mostly happens when there is light gray, but not necessarily, and a soft reset for the phone does not remove it. It happens on random!
Hey,
Yeah it happens to me too! You don't need to do a soft reset, it actually fades away if you watch it closely! I don't know what it is either, and yes it is random as you have stated! I initially thought it was an application I installed as it only started happening after that, so I did a full hard reset and its still happening! Not sure what or how, but hoping next firmware version stops it!
Cheers,
mpls-te
As it happens, that's exactly why I've logged on here today! Any ideas whta the cause might be?
OK, good to see that others have this, so am not alone here, experts here, any ideas? other touch pro users, can you please leave your statements?
I hope its a driver issue.
But from what i noticed, its like, the screen is OFF, as in blank and no back light, but somehow, the application working on the screen before you turned off the device is somehow printing something on the LCD, something that we don't see, and when we actually start the phone and its back light, that OFF LINE imprint pops on screen. Something like that.
Its completely illogical, but dunno, can't find any sense here and am going crazy
Same thing happened to me and a few others as well.
See my thread here.
What rom is everyone using?
I've noticed a similar issue with mine, except rather than something software it seems like it's the backlight for the bottom 1cm of the screen flickering slightly. I don't see any weird pixels or inappropriate screen information, just a dimming/high speed flickering of the backlight in that same regionas yours. It comes and goes. Sometimes weeks without it, then maybe 3 times in a day for a minute or two at a time. Everything else works fine and whatever screen I go to displays fine.
I'm assuming it's a hardware problem with the LED(s) that light up the bottom portion of the screen, and I'm going to use it as an excuse to get a warranty replacement somewhere near the end of the warranty when the phone's getting a little old and worn.

Lool, evil, lets just hope that this problem DOES occur when you go to their shop for your replacement
Good idea though, might do the same thing except that i have to travel abroad to where i got the phone from to actually get the warranty working. Don't forget to re-enable stock SPL and stock ROM
It happens frequently enough I'll be able to get it on video just in case they need proof, but typically they just exchange by mail.
I just posted in another thread about this issue. I have run into the same thing a few times. The bottom portion of the screen flickers, and when i do things that have a dark gray or black screen I can see a ghost image of the left and right soft keys from my TFL3D home screen. It seems to be most noticeable when the screen brightness is set to max. To get it to go away I usually do a few soft resets, and then, if needed, i will turn off the phone and take the battery out for a while. I have never tried waiting it out to see if it will just go away on its own.

I see that everyone posting in this thread,that has their signature filled in, is using the Energy ROM. I find that very interesting.
i am having the same problems, sometimes touchflo3d will flicker at the bottom, near the edges. I also get text that can be read through other screens. Like on pocketshield i can see the left and right softkey words still at the bottom. its so odd !
P.S im on energyrom
I'm on NATF v2.2, not an energy rom. But then again, mine looks more like a hardware issue, as I've never seen any ghost images of text or softkeys, just flickering.
can somebody post screens?
maybe the same problem here...
hardreset, other roms > problem still there:-(
Same problem here and I am using stock rom!
here are 3 screens of my xda diamond pro, using latest official o2 rom and newest romeOS eng

Well, i doubt EnergyROM has anything to do with that problem, since my Stock ROMz had same problem, never got fixed with any updates HTC used to release. MAYBE some Cooked ROMs out there have this solved, if any, please let us know And my problem is nothing close to screenshots above :S

Dude, those photos are awful, after seeing them am happy with my phone flickering, its nothing close to this.
You see, in your photos, all three of em, you some kind of shadow effect, where text of a button for example has that same text beneath it 3x6mm, that is not my case at all.
My case is as follows, IF i am on the home screen for example all looks ok, except that the bottom 1CM of the screen is flickering. If i go to another window, either a total black one or any other screen, i would still see a ghost of the old home screen, for example, and only at the bottom 1CM.
Will post photos once i get my cam back. Cheers
similar issue
my issue is kinda similar, instead of getting the bottom 1cm or so discoloration or stuck pixels, I get streaks of red or blue on my screen. I have had this happen on each version of NATF I have tried, but don't remember it happening on the stock version (which I am tempted to try again to see if that's the issue).
Could this be a driver issue?
mind is even worse than all you guys, the touch screnn dose not response, and i have the energy rom on it, before it goes wrong. it just suddenly dose not response, than i send it to HTC, they ask for 425.00 for fix.... I will just send this to Asia and get some one to fix it.
But I hope before i send it out, some one can help me here.... anyway can fix it easy!!!!
Hi all, i have the same problem, here's another topic about it

Home button Light always on

The light behind the home button on my Fuze came on yesterday and stays on. It comes on as soon as you turn the phone on. It's very, very bright, much more so then when then lights come on behind the other buttons when they go active. Makes it hard to look at the phone. I pretty sure it's a hardware short but I thought I'd double check on the forum so see if anyone thinks it could be software or some setting I don't know about. Not as strange as it might sound. I've had other issues where setting got changed when the phone was in my pocket.
I'm not looking forward to trying to disassemble this thing. The Hermes was enough of a pain. I'm guessing this one is worse.
Thanks
I have the same problem since yesterday, so if anyone knows the solution I'd appreciate if he can share it.
Thanks.
The issue has gone by itself, so I presume it was some hardware issue caused by excess moisture (phone had contact with my wet hait/ear when I had to answer call when I was in the shower... too many information for some, I know )

Problem with the proximity sensor, please help

Hi all, I have a weird problem with the proximity sensor in my HTC Titan. I got a new Titan about a week ago, to which I immediately installed HSPL and Dynamics rom. After I did all the tweaks and installs I like, I noticed that every time I dial a phone call the screen goes off and stays that way until the number I called answers. If the number does not pick up, only thing I can do is remove the battery basically to hang the call up. I noticed that removing the back cover slightly affects the issue and its easier to get the screen back on (by pressing the power button), but still removing it does not solve the problem. With a handsfree I can actually stop the call as it has an accessible end call button.
I tried flashing another custom rom and also a stock rom, both had the same issue. So, I took the device for warranty repair. I got it back today from HTC, with a note saying that software has been updated and problem has been fixed. I tried the device and surely it was working. Well I can’t live without an fully unlocked device and against my better judgment flashed a custom rom again… And surprise surprice the problem appeared back.
Im thinking here that could I adjust the proximity sensor from the registry, if its somehow too sensitive or something. Strange part naturally is that other people with same rom are not experiencing this behavior, so it is device specific problem. Also I don’t think I can take the device back again and say yeah I was flashing some custom roms on it and lost whatever you did with it.
There a Proximity folder at HKLM and I tried changing some values there but no affect at all. It probably would be better to have someone who understands about the values little try to take a look.
Thanks a lot!
It's a hardware problem. I got the same issue after 2 months of use. I sent to repair but they wanted to charge me to do that, so I haven't fixed it but I still can get the screen back by pressing and rubbing my finger on top of the sensor.
But when I got it back from repair today it was working. I made few phone calls and it was working totally like normal.
you are not alone

I can tell you that you are not the only one with this problem, it happened the same to me. I'm still unsure if the problem is hardware or software, but I think it's software because it happened just after I install Dynamics_2.0_Titan. I really wish that someone will bring a good solution for it.
