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
Today this has happened twice in same day -When ever my Vox is lying Ideal the network indicator blinks also if its on charge i wil get a orange LED.but if I press any keys (lets assume to make a call) the Screen still remains Blank...
This problem I had also faced earlier my O2 NEO (Prophet) before it went dead completely!!
I am worried is it an indication of slow death!!
P.s I dont wanna lose the vox as i lost my beloved prophet
Still waiting for some useful tip
which ROM?
I guess you are talking about similar problem as what I have.

I usually get this problem once in every two days. I uninstalled all the extra apps leaving very few which I am sure wouldn't cause any harm. Since then I haven't seen this problem. Its been more than two days.
What I do when I get this problem is, remove the battery for 5 seconds and put it back before I attempt a restart. I don't think you need to worry about this too much if not for the calls that gets lost when the phone is in this state.
Sometimes it happens to me where the screen, once it goes blank, will not come back on. I usually just reboot it and forget about it. I've had my vox for a year and its happened on every rom I've used probably about 5 or 6 times.

Actually My vox does not show any thing on the screen totally blank and just the GREEN LED (network) blinks...
Thats also true tht I sometimes goes off completely and its too hot to handle.
In my case (blank screen) i usually make a call on my cell and it comes out of the blank screen to display incoming call...
I guess u shud try the same thing rather thn removing the batt ...as i had already lost my O2 Neo in the same manner.!!
I think we still need a solution on this
Ps. My ROM is Windows mobile 6.1 v1.0b for Vox by Dr. Martin Gonzo

Hi.
My Touch Pro is acting somewhat weird.
The other day I walked in what best can be described as moist weather. It wasnt raining but it wasnt dry either. I had my headset on an the radio running on my touch pro. No problems. Later that day it freaked on me.
The backlight wouldn't turn on no matter what i did. Until i soft reset the phone. Then it turned on until it went to sleep by itself. Then the lcd turned off but the backlight stayed on. One hard reset later and it was fixed. A few hours later i recieved a text and it took forever to open the messaging app, and as soon as i startet typing on the keyboard it kept turning the light on and off, and the caps an fn lights cycled on and off also. I had to turn to the soft keyboard to answer the text. And the phone now seems REALLY slow and unresponsive, like cpu cycles are being used. But nothing is running on the phone.
And thats basicly how its been ever since. I can se both the water sensitive labels have turned red, and i sure that its because of my walk outside.
I've tried hard resetting, flashing the original rom, flashing a new 6.5 rom, drained the battery completely (not that hard because the backlight wont turn off) and off course fully charging the battery. Nothing seems to help.
Any ideas of what to change, or ways to fix it. Theres no warranty on it, and even if there was they wouldnt touch it because of the water sensitive labels has been triggered.
Any help is appriciated.
Im thinking of buying the tattoo instead if it aint feasible to fix it, but im really hoping cause im not sure i can live without the hardware keyboard.
Hi! Two days ago, my phone dropped in water , i put them immediately in rice until today. When start it with the power button, i felt the vibration and i hear the open sound. But the screen remains black... but i discover that it was just the backlight because when i watch the screen under a lamp i can see the interface and slide between pages... but its very dark. Is it possible to change this backlight? or just wait few other days to allow time to dry fully. I welcome your suggestions! thanks

When there's water involved, IT's hard to know exactly what damaged. Could be just stain on the ribbon connectors, a burned fuse/diode/resistor (all of them micro sized) etc.. or just the LCD's backlight damaged entirely.
Keep it on rice for more time. I would make the battery to discharge to 0%, But it's also more recommended to keep the phone OFF. Only my friend LUCK knows.
To change the backlight, the whole screen needs to be changed.
Backlight died on me. Possible moisture.
First, it was on boot loop (on stock rom)
i went to restart it (holding power button and volume down)
then the screen turned bright white, restarted it and then the backlight died, dismantled the phone, now still in rice, also happened on 2nd April.
Any help is greatly appreciated.

Took it apart down to the Screen (not the screen layers), left it in rice, works like a brand new now. Cheers.
I just replace all the frame and lcd for a new on my nexus 5, but the problem was still there... no backlight, i can see a little bit the screen, but it's very dark... do you have any idea for try to repair this, because now i don't think that it's the screen but more a motherboard or power problem for the backlight :S
exactly same problem here
nexus 5 phone dropped in water.
Backlight went out permanently - rice didn´t help.
Can see the display working using a flashlight - so rest of the phone seems to be working ok.
Just pruchased a new screen, put it all in and still the same problem: display works, touch works, backlight is off.
So it seems the backlight part of the display receives no power - anybody has an idea how to fix that?
thanks
I have answer to this!
I have had this problem like 3 months now and i finally fixed it.
Basically what i did was that i bought a broken nexus 5 (only the screen glass was broken) and tried to swap every part one by one. The one that was not working was the main dock!
It is a cheap fix, like 10£ on Ebay.
I am writing this post because anyone else haven't.
I hope that someone sees this.
I now copy this message to all other threads so people can fix their nexus 5's
PS:as you can probably tell English isn't my first language.
Hello! I am having the same problem. The cell phone fell to the floor and the next day the problem began. The display is not broken.
What are you taking about when you say "main dock"? Motherboard aka mainboard?
Thanks!
Hi,
I accidentally drop my moto g into water, since it's only less than 10 seconds I just wept the water from phone without put it in a rice bag. I turn off the phone and wept the phone surface till dry and turning on again. The phone start normally without any defect but I notice that my LED always turned on even there is no notification. Later LED notification is died (a least i think it's dead) because even there is a notification it will not turn on.
I think LED notification is short circuited, If there is a way to change it / repair it ? I really thank you if anyone could tell me how to change it (video preferred) and tell me where to buy the spare part.
Thank You.
Bump up... hope someone can give me right path
