Screen going black

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.

Need Help! screen problem with VOX

hello guys, my first post to this great forum
first of all, i just recentrly bought a HTC S710 /VOX phone
great smartphone in fact, but the problem is
sometimes, when i press a button, the screen just goes black,
the phone continues to run though, i can receive calls, access programs and all, but i just cant see.
but, if i wait a couple of seconds till the screen "darkens" to start saving battery, the screen now shows in full color, after that, i have to wait for the phone to stay completely dark in screensave mode, otherwise, if i click a button before, it shows the screen in full color but right after it darkens again...
can someone find me a solution for this? im really desperate.
as i said, the phone continues to run normally, the screen just darkens, stays black, have to wait a couple of seconds for it to return to normal
much appreciated
anyone?

Anyone know something?
now i spent the whole weekend without the screen going black.
bust just right now, after i syncronised it with my pc... the screen went black again,
turned off the phone, and turned it on again, and the problem was gone...
any ideias for a solution?
much apreciated
cheers

problem still persists
but now, its not that often...
it can go by 2 days without the screen going black
but when it does, its really annoying :S
any ideas?

I have the same problem with my Vox. I tried:
-various rom updates,
-disabling the light sensor and
-messing arround with all other backlight/powersave settings.
Nothing worked. Ideas anyone?

problem still persists today any hopefull ideas?

if hard resets have not helped and you have tried other roms, then the problem is with the device not the os.
so for this you might want to contact the htc service. no other solution.

tks for the tip prajith
guess i'm in no luck then
i've tried hard reseting, changed the rom
but since i reside in Maputo - Mozambique
we don't have a htc center here
maybe in south africa our neighbour country
but anyways, guess ill just have to get used to it
tks

oh alright.
so where did you buy your device from? can't you ship your device for service. it does sound like a irritating problem to live with.

Phone doesn't boot anymore - broken?

Hello everybody,

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...

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)

Orbit 2 White Screen need help.

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

Losing touch

sometimes when im typing away in a message on my phone, some parts of the phone turn into resistant areas making me press hard on my phone for a touch response to occur...so the phone turns from a capacitive touch screen, to a resistant one that requires a considerable amount of pressure from my fingers. Why!!! is this because of a rom im using? when i click the sleep button on and off the screen returns to normal, but this is so frustrating when im attempting to type long messages. any answers? thanks!!!

I had that issue once.. I tried calibrating the screen but it didnt help so I did a battery pull and it went back to normal.. Havent had the problem since then but im scared itll show its face again..

hah yeaa aafter posting this i havent had the problem, lol lets hope it doesnt come back!

OP are you using a gingerbread rom? it's a VERY VERY common/known issue in all gingerbread roms from gingerbeast to ARHD. I don't know if there's a fix in the works or if anyone cares to make one but i think everyone just flashes teh screen on/off to get around it.
