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.

Sam problem here,
i called with HTC and they sent them to there repair centre.
So I searched everywhere and can not find ANYTHING on such an issue...
A little history on my phone, previously cracked the digitizer but replaced it with no issues (except for a minor cosmetic scratch on lcd, barely noticeable) about 3 months ago, has run fine since then, never any issues
I am running ICS under HD sensation rom, never any issues
I occasionally had some touch screen unresponsiveness, but a quick turn off and on of screen would fix this, a pretty common issue for this phone
The Issue:
today for some odd reason my phone screen would turn on and would be just random pixels of varying color, not correlating to lock screen at all, a reset of the phone did nothing for this, but strangely enough pressing very slightly across the whole front of the screen would return it to normal, if a bit briefly, so i concluded that a wire connecting the screen had come loose, or there was dust inside the phone, so i took it apart and made sure everything was a-ok, which it was, but after putting it back together the same issue persists, and has in fact gotten progressively worse throughout the day, it is now to the point of being unusable, has anyone experienced anything similar, or does anyone have any solutions? i would rather avoid a new phone if possible...
AnyOne??
I'm also having the same problem with my HTC Sensation and tried the master reset and inserting a new SD Card. Did you figured out what was causing the problem? I appreciate any info.

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.
So about an hour ago, I tried turning on my HOX from sleep, and to my horror I SAW NOTHING ON THE SCREEN.
After a while, I found out that the touchscreen was still responsive, and the bottom buttons were still lit. I tried to hard reset t by holding down the power button, but when my phone would restart, I would feel the vibration, but the boot screen/splash screen/EVERYTHING was pitch black - nothing showed up on my screen.
So I played around with it, knowing that my phone was on, but I couldn't see anything. I figured out after a while that if I pressed REALLY hard on the edges of my phone, my phone would flicker on - which proved to me that it was some sort of backlight issue.
All of a sudden, about 5 minutes ago, my backlight returned and everything is back to normal.
But now, I'm deathly afraid that it might happen again. What should I do? Should I go and get a replacement? Was this a freak occurrence? I'm on edge here :\
Why are you asking?! Go get that sucker replaced!
I'm hesitant because my current phone is rooted-ROMed-customized like crazy, and I was hoping someone would say something like "Yeah that's a one-time freak accident kind of thing", which would make it so I don't have to redo everything, haha.
Well in any case, since I'm here now already (and I know I can search the development forum) - what's the state on rooting/unlocking the bootloader for the newest HOX firmwares? Are there any issues with rooting/unlocking? Or is it a pain-free process like it was back in June-Julyish when I got mine?
lol I would def return it. I had similar issue . Here is a link for any rooting needs as well as how to relock and unroot your phone.

They will most likely honor the warranty because it could have just as easily happened to a non rooted phone.
Replace it.

A couple weeks into using my new nexus 5, half the touch screen stopped working (if you really had to, you could still press buttons by pressing the thing really hard). It seemed like it was a hardware issue so I unrooted and wiped the device with this guide
http://forum.xda-developers.com/google-nexus-5/general/tutorial-how-to-flash-factory-image-t2513701
with the intent of returning it. Part of this process involved TWRP (where there are touch controls), and the problem occurred even there. (to me, that seemed to confirm it must be a hardware issue).
Now after everything is factory-reset, the touch screen has magically started working again. I'm extremely confused how this could have happened. My best guess is that the issue was intermittent and i accidentally jiggled the phone in a certain way to make it start working again.
Does anyone have an idea what could have happened, or how I could stress-test things to find out? If it is indeed an intermittent issue and the phone needs to be replaced I'd like to do that ASAP because I'm leaving the country and dealing with warranty will be difficult from overseas.
