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.
Hello everybody,
i and my Vox are having a really weird problem. I was surfing the Internet with my Vox yesterday and all of a sudden the phone turned off, nothing on the screen, backlight off nothing. I tried to attach the power connector to it to see if the orange light even starts but it isnt... i tried hard reset but still the phone looks like its got no power. This morning my alarm set off on that vox the key for dismissing the wakeup thing worked but no backlight, nothingon the screen really nothing...
Does anybody know how to solve this? Im really looking forward for your answers
Thanks a lot jon

If you can, reflash it... If not, it might be a ram failure, and you will have to send the phone in.
well funny thing is that flashing works perfectly but from the outside the phone looks completely dead...
if ihave to send it in it might be cheaper to buy a new phone i suppose, because i cannot find the receipt for the damn brick anymore.
anybody got a last solution for it? (except the rubbish bin)
Hi all.
I recently came into the posession of one of these awesome devices.
my only problem is that when turned on, the screen comes on but is just pure white.
the device seems to boot up ok as you can hear all the noises in the background, also the digitizer works as the backlight comes on when you touch the screen and you can hear windows mobile clicking away.
could this be the lcd thats broken? or could it be an issue with the mainboard?
anyone have any ideas? or have had the same problem?
i just dont wanna go out and buy a new screen to find out thats not the problem lolol.
(btw i have tried hard reseting multiple times and that dosent seem to be the problem)
thanks all.
Um how du know that you have HR properly if you cannot see the screen, or can you see it on the HR screen?
Also if you can can you see the bootloader, and have you tried a different rom, never know it may work
heya chris, thanks for the reply.
reason i know it has hard reset ok is i used a htc touch next to it to guage where the setup screen (screen calib etc) buttons were and tapped on the digitizer unitll it got to the main screen and reset itself after customisation (took friggin aages to do that lol)
then managed to fudge it to get media player running by using the arrow buttons etc.
sayin that what combo of buttons do youse to HR. ill give it a try if theres another way ;-)
For me its ok and windows key, the one beneath the send and end keys
Then when booted it will say "blah" and press send to restore. Press send then it will take about 15 seconds or so to restore then it reset's and boots up again.
To do the bootloader its the camera button and reset, but i dont know if thats helpful if you cant see the screen!!
Um is it still under warrenty if so go that route and if not try taking it apart and then try to see if any of the screen connectors are loose i think that someone has done this already on here with pictures if you want some help with it.
tried the hard reset again and still met with the same white screen. dang...
as for warranty, its an ex business phone i got through my work so no warranty, and i have since stripped it down 3 times to look for faults.
have tried slotting the ribbon cable in and out of its socket and had no luck.
hmm i would say maybe new motherboard or screen, which you prob already know by now.
Apart from that im out of ideas as to what to say would be a solution for the problem with it or how to fix it without replacing parts
cheers for all your help chris.
i think ill just have to take the dive and order a new screen.
god i hope its the screen lol
I have read this forum and many other internet sites until mys eyes cross!
I have Sprint HTC Touch Pro2 running winmo 6.5. duelboot android.
I have flashed many times and the problem isnt fixing itself.
Its like when my backlight goes to sleep I cant wake it up. I can still here the
phone ring and answer it.. just cant see anything after it has gone to sleep.
In Android i dont have this problem..
Anyone know where the registry is to do some editing??
Your help would be so APPRECIATED!!
Thanks in Advance.. Tammy

I Have the same issue. I Recently tried to flash back to 6.5, and somehow it all went wrong and i got the white screen of death. i could get to the boot loader(tri color) screen but it would just go right back to that White back ground with Green letters 'htc'. Now I finally found the post that helped getting to that tricolor screen then loading rom. IT WORKED! then i tried the sleep/ pwr button and sure enough it STILL WON'T WAKE!!!! Seems like the only answer is to break down and get the droidX. but i need windows for a 3rd party program i use....so i might just stick to the lil slide fone i have as a back up...
I just leave the light on 30% if Im expecting any txts or calls, when Im not I just turn the light out I can still hear incoming calls and if I hear a couple txt I pull the battery and stick it back in so that I can see the screen again.. its all I can do for now.
Im amazed with so many smart folks here I havent had anyone offer any fix's yet??
I have been hoping for easy registry fix.
Good Luck and please let me know if you get any help with yours??
yes, its becoming a problem. pulling out the battery to get the screen is more damage than good
Hey guys, i'll try to explain the situation as best i can below, hopefully someone can work out what is wrong.
My phone is about 16 months old. About 2 months ago i dropped it twice within the space of a couple weeks. There were a few cracks along the screen, however it wasn't very noticeable and i wasn't going to bother having it fixed. The problem started a couple of weeks ago when i went to grab it out of my pocket, however i found out the screen was black and it wouldn't turn on. I don't really know how to describe it but it was acting very strange...
- The screen would have white/gray bars all over it then turn off, then it would do the same with very thin vertical lines that were white/gray/other colours...
- When i get the screen on, it generally turns off again within 30 seconds, however it can stay on for a few minutes.
- If the screen is on and i press the lock button, it almost certainly won't come back on.
- Restarting the phone or holding the power and volume button nearly always gets the screen to come back on. It often then restarts but turns off again shortly after.
- The phone is otherwise still working when the screen goes off; the notification light stays on and i hear messages etc coming through
- The backlight often stays lit, revealing a gray screen opposed from total black. Sometimes it does not stay lit however.
- When the screen came on it was often unresponsive to touch
I had the screen replaced yesterday by a phone repair shop and the phone is still not right. I have factory reset the phone and also wiped the partition cache. Other than that it is still not working. IT seems to be working better... The screen always seems responsive to touch when it is on, and it doesn't seem to be turning off as often. It generally starts up and works fine when i start up by holding the power button and down volume button together... However even still it sometimes just flashes up with a few thick white/gray and black lines on the screen..
Does anyone know what can be causing this and how i can resolve it? If you need any more information please let me know and i will try provide it. I could try get some pictures of what the screen is doing when i finish work. Thanks guys, i appreciate any input.
EDIT: I managed to get a pic of what i mean by the thin vertical lines all over the screen. This just appeared when i tried to restart the phone after it the screen had once again stopped working. The imgur link is gIFMGD6
Anyone have any ideas?
Hey, did you ever figure this problem out? My phone just started doing the same thing. Can't find much info about it.

Yeah, i had the screen fixed hoping it would fix it, however that didn't work. Turns out it was the motherboard, don't know what was wrong with it in particular other than it was simply going faulty. Had someone replace the motherboard on it for $50 and have had zero problems since! Hope that helps you.
Thanks for the response. I tried replacing the screen too with no luck. Unfortunately the same place that replaced the screen said it would cost $400 to replace the motherboard!!! The phone cost less than that so it looks like I'm gonna buy a new one.
