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.
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.
Hi everybody,
I recently dropped my phone (HTC Sensation) and here is a list of the different things which happened since then:
My back camera doesn't work anymore (the original app closes when I launch it)
My front camera works with green lines in the middle of the screen
My battery dies pretty quickly (I loose 50% battery in 8 hours in sleep mode and plane mode without touching anything)
Unfortunately my warranty stopped few weeks ago and I don't know if I could find someone skilled enough to fix my issues in a phone shop.
So I have few questions:
Is there a way to diagnosis if my back camera is really dead? If it is dead, should I try to change it myself or is it risky?
Is there a way to fix the green lines issue on my front camera?
Regarding the battery, the power app says that its health is good (and I used an other battery and the result is the same) so it is probably not a battery problem. I also hard reset my phone, it didn't resolve the problem. So do you know if it would be possible to diagnosis the phone and find out where the probleme comes from? Or is it definitely a hardware problem and should I accept it and change the kernel (underclock the processors, lower the voltage) and find a customized ROM to save more battery? If yes, do you have any advice or combo for me?
Thank you guys for your help
Does this mean that it is impossible to diagnosis and fix my mobile phone? o:
I have a photon Q LTE
Something is terribly going wrong with this one , first the front camera stopped working , when i click , nothing happens , the button is greyed out i thought it was software so i factory reset , still nothing rear camera is working fine though.
then when i opened the keyboard the touch screen becomes disables , i can't do anything on via touch screen when keyboard is opened.
then now touch screen completely stopped working
i think hearing songs in bathroom was not a good idea , moisture got in , i believe , i tried many ways to dry it out but eveyrthing is becoming worse.
i am out of warranty and sprint charges 50 dollars and not guarantee of any recovery
any help would be highly appreciate.
All of the things you describe indicate some sort of hardware issue - with water certainly being suspect if you think it got into the device.
I'm not sure what we can suggest exactly, other than the obvious - throw it in rice and hope, although most of the components are sealed, so if you are experiencing issues it is probably too late.
Happened twice now on back camera. After unlocking and went to camera, it cant focus on anywhere. Everything is blurred even if touch the screen to focus near or far.
If i give it a little shake everythings going back to normal. 2 weeks i have this unit and it happened twice. Is it normal or my unit has a defect?
Thank you
Edit.....it only focus near..like macro shots cant focus more than that. Happened after pulling it out of my pocket after a long walk...
Happened to me too on camera mode

I hope someone can answer this...will wait for their opinions.
Have not encountered this. I use my camera heavily.
I advise going to a Samsung service center and letting them debug it.

Same problem here. All of the sudden my back camera is blurry... No idea what to do...

EDIT: After I've shaken the phone camera works again...

I read this somewhere that there are some encountering this. They clear camera cache (in which i tried and luckily a good start) or simply tap or a little shake your phone and focus comes back again.
Hope it will not occuer after clearing camera cache

I cleared the cache before I shook it. Didn't help.

My phone do the same. Tap your phone on the side, and focus will be on.
If shaking the phone fixed it the problem is likely a failing ois mechanism. I would swap asap.
