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.
Firstly, my screen does not show visuals. I can still touch the screen and make things happen, but it is just a back-lighted black screen. I have answered calls on it and such. Basically I'm returning it and getting a new one.
Since I am getting a new one, I want to see if anyone ever heard of this problem and to see what the cause of it is, for prevention purposes.
I didn't get it wet (the white sticker in the back is still white.) Though I have flashed PROven ROM to it a couple months ago (it's a great ROM by the way), but could that have messed up my screen?
I also wanted to know since I can't see the screen, would I have to, for warranty purposes, (blindly) reflash to the Stock ROM?
Thanks in advance!
Yeah, you probably oughta return it to stock configuration (good luck on that!). If you're really lucky, that might even fix the problem. Have you done a hard reset yet? Might be worth a try, although it certainly sounds like a hardware problem.
Sounds like the flex cable has gone bad
Exactly same thing happened to me this Tuesday. Luckly I backed up info to memory card using PimBackupV2.8 with remote control software on my PC. With the remote contol tool, I could see everything as if on my phone and icons are clickable.
Hard reset did not fix the issue. I then flashed the shipped official ROM and stock SPL for warranty purpose. Will send the phone to them today for repair.
mine also like that..
from vodafone also..
the things that make me panics is the phone become hotter and hotter.

Summer is coming...
Sometimes they make updating phones too easy......
The back of my phone often gets hot I have to use the edges to hold it even though it was not a hot day and it is in my pocket.
blank screen
ya so my screen is blank white
but everything else works
i've heard something about this being a faulty "flex cable"
how can i fix this?
thanks so much for your help
how do i fix this???
did you eventually find out how to fix this/???
u ever end up fixing that? how?
thankss
Mine was still in warranty so I rang Vodafone. They sent me a special delivery envelop the following day. I sent it back to them. The following day I got a text message from them saying they got it and was working on it to fix the fault. The next day received another message saying the device was on the way back to me and I should receive it the following day.
Actually they sent me back a replacement
So.. basically.. is this a faulty flex thing?
I had the same problem for the last week until today i was about to buy another one since i dont have any warranty for this one.. I searched google and saw somebody say that just putting a business card between the keyboard and the lcd and then slide it and it works so far
hope it helps everybody
Ack! my Fuze, which I got off eBay a few months back, just went black too.
I'm not exactly sure whether it's the LCD or the flex cable, but the fact that the D-pad backlight also has become intermittent makes me think it's the cable.
So has anyone attempted the flex cable repair themselves? I see you can buy the cable for around $40 and the LCD for around $80 from Hong Kong.
Maybe this is a sign I should just get an Android device.

Did you end up fixing it? I have the same problem.
same thing happened to me Twice.... in my sleep overnight. I LOOOOOOOOVe my raphael but man this was the last straw
This maybe of some help for those of you with blank screens. I bought a Touch Pro on ebay that had a very dark screen, occasionally you could just make out some icons being displayed. Using Mymobiler showed that the basic system was working, as was the touchscreen. Other symptoms were that the camera would not work and the keypad lighting was intermittent. Sometimes on connection to Mymobiler a dialog box would come up saying there was an error with Microp?!?
Despite cleaning all internal connections and ensuring they were correctly and securely made the problem remained. I then noticed that the small camera used for video calls (in a socket on the main flex cable) looked very dirty and corroded. I removed the camera module and, using a fibreglass brush, cleaned the contacts on both the socket and the camera module. These were very badly corroded with verdigris.
On putting everything back together I was most surprised to find the screen was now working, as was the main camera. Unfortunately the ROM that is loaded doesn't seem to have any facility for checking the front video camera. There are still problems with sound - both the loudspeaker and the headphones seem to be dead and I have not had the opportunity to test GPS, Wifi, bluetooth, buttons, etc, however I will keep working on it.
Hope this is of help to someone.
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 !

Hi,
I recently replaced my cracked screen and all went well, expect that now the proximity sensor doesn't seem to work 90% of the time. When I make a phone call the screen goes off and it won't come back on when I move the phone away from my face. Either party has to hang up in order to get the screen back on. I've opened the phone up and double checked the ribbons and cables, everything seems ok.
The sensor itself appears to be fine, it's connected direct to the motherboard by the looks of things. I've wiped the phone completely just in case it was software related but that hasn't helped. Has anyone got any advice on how to fix this? I guess I could try to source a broken One S and replace the motherboard, but I don't want to spend too much on getting it working.
Any troubleshooting advice most welcome..
Cheers...
Mines been doing this since the htc repair centre had it,but its got a lot worse recently, proper random though it will work say 10% of the time.
I can't help with the sensor but I set the power button to end calls, its in the accessibility tab in settings, does make it impossible to use the key pad for options on phone calls though.
Hello guys,**
Well few days ago I accidentally dropped my Nexus 5 in a glass of water for just 1 sec. So I immediately switched it off and wait a bit to let dry then restarted it, and all seemed to work fine. But just some days later and up to now the phone boots up all fine as usual to the lock screen, and from there I can pull down the notification bar (and navigate through it, activate/deactivate wifi, etc..) but when I unlock it to get to the home screen it becomes all back and nothing appears on the screen even though the phone is still on.*
It's really confusing and weird. When I call the phone it rings (so no signal or sound problem) but I can't still access the screen to take the call as it's all back and unresponsive.
Following some suggestions I disassembled the phone and cleaned it dry but same results again! So now I think the problem is somehow related to the motherboard, coz as you might notice on some of the pictures attached, it seems that some plastic parts have melt down to cover other smaller parts. Anyway guys,*I'm just wondering if some of you guys had experienced something like that and if you were luckier*to find a solution or any directives that could help. Or you even think that's a motherboard problem like, do you know any ways to fix that o buy a new one somewhere??
PLEASE!!
Sorry apparently, I can't publish links until I get like 10 posts or plus..
But anyway guys, I'd really appreciate your help.
Why did you power it on and short circuit it on purpose for??

@SekouCheikh
Maybe it's a coincidence that you dropped it in water and this happened a few days later. Once in a blue moon mine does something similar to this (although not usually as start up only after lots of use), but I think it's related to an app or xposed. I only notice it after installing a bunch of crap again. Maybe try a factory reset (do it though the computer) just to see if it is somehow not hardware related? That's what I would try first.
Help please
Ttt
Wait... Are you seriously posting from 2 different accounts??
<...>
First, simply try to factory reset or flash a new rom. There is not enough evidence to be sure it's a hardware problem, it could just as well be a coincidence that it started happening just now.
