hey everyone ..i recently upgraded to Ivan wm5 V4R3 and im having some small issuses with the backlight and wondering if anyone could help me solve them.
if the phone is sitting on the table... untouched.... with the screen off...sometimes at random intervals the backlight will just suddenly light up.....this is extreemly annoying in the cases where it is either in my pocket with the screen off... then it will suddenly turn on and then the touch screen is active in my pocket... or it is on the table in my bedroom... i am almost asleep... and bang.. on comes this bright light that lights up the room....
this happens when the fone is not touched.. charging and also when not charging... docked and undocked.... or when the screen is off ..... or on.. any help would be greatly appreciated...

I was experiencing the same with ivans ... but it only happens when the bluetooth is on.. if you turn the bluetooth off.. it should not happen... try it..
For some reason I've noticed this bug on TuMa 1.4 and Logout's ROM, but didn't seem to notice it on TuMa 1.3....
Turning off the bluetooth does indeed seem to help, and thus saves a large amount of batter power.
its due to the bluetooth reset on resume fix, it stops you BT turning off but it also makes the PPC wake up repeatedly. I recommend using a 3rd party program with a 'stay off!' function. I personally use Mortsaver as its freeware and i love it
i have set the back light to turn off after one minute in external power.
usb sync cable connected to pc and back light will go dimmer in one minute but not complete off.
anyone has this problem?
this seems to be the new behavior of the TyTN II vs. the old TyTN: The back light never goes completely off. You have to push the power button to put the unit in standby. When I listen to music, for instance, I want the backlight to go off to save power: I must push the power button to turn off the backlight. The music still plays, which is nice...
Anyway I'm not sure what to do about it when it's connected to a computer to sync, since pushing the power button would likely interrupt the sync. It doesn't bother me that the backlight doesn't go off.
Hi
I'd go as far to say this is the new behaviour of Windows Mobile 6. The Toshiba G900 was exactly the same. It is possible to get a small app to turn the backlight off completely however when it's connected to your computer via USB it isn't drawing power from the battery but from the computer so it doesn't matter, and it's just show you it is still on.

8525 running Black Satin WM6 doesn't do this, I don't think it's WM6
rite i dont mind the power consumption, but i cant go to sleep with the light on next to me, i like it off completely to save screen life too.

With all due respect that is a cooked ROM and will not need to follow WM6 best practice or MS guidelines.
I think this happens with the Kaiser (like it does with the G900) because the LCD isn't transreflective. With a transreflective device, even in normal room light you can usually see what is on the TFT display, so the device can time out the backlight completely turning it off, and you still know it is powered on but just the backlight has gone off. With a non transreflective screen like the Kaiser, if the backlight did go off completely while the device is still on, you can not see anything on the TFT screen, so it looks completely off, but it isn't. So I think the dimmed backlight is so you know it is still on by being able to see something on the display.
You can see this happening on battery power. If the backlight is timed to go off before the device powers down, it doesn't go off completely but dims, then shuts off completely when the device goes into standby.
but i cant go to sleep with the light on next to me, i like it off completely to save screen life too.

You have a few options:
1) Power off the device.
2) Press the standby button.
3) Turn it upside down or cover it.
4) Download this application that will let you turn off the backlight completely. http://ppcsoft.narod.ru/english/

This will be making little different to your screen life. The backlight is made up of white LEDs, these will have a lifetime of around 50,000 to 100,000 hours (more when used at a dimmed setting) so will easily outlast the device even if running non-stop from the day you buy it.
Best Regards
Phil
ic, as long as its ok for the screen life i am cool with it. thanks for the input.

This app would be good except that when you set the action to turn the light off in say 15 seconds it only does it the first time and then must exit itself because it won't do anything further until you reload it.
I need a program that stays resident and turns the light off after a set period of time. Pressing the power button isn't good enough because that stops a lot of apps running by putting the Kaiser into standby.
Anyone know of a program or fix?
The 8525 turned the backlight off no matter if you used stock or cooked ROM. The 8125 was the same way. Not until I got my Tilt did this "feature" arrive.
There may be some kind of a flaw in the programming. No, that never happens with a M$ program.
I was having the issue described in the thread, backlight stayed on. I played with my power and backlight settings and while searching for the answer my screen dimmed, even though it is connected via USB. I think if you go back and reset your backlight and power settings, that you will then see the desired effect on the PDA screen.
My settings:
Power= On Battery- 1 minute, On External- 2 minutes
Backlight Brightness= On Battery set to middle (half way), On External set to full
Battery Power Tab and External Power Tab- both set to 1 minute
The end result is that after 1 minute my screen dims to the lowest backlight setting. Screen is dim but I can still read what is there.
This is a very old thread, the backlight is always on because the Kaiser's screen is not transreflective like it's predecessor Hermes. If the light is out you will see nothing where you could with the Hermes. It's just the way it is with this model.
I have another question which it is related with the backlight and power off.
I tried to power off the phone by pressing and holding the power button. It asks me to confirm it. However, after the phone is "powered" off, it seems can be turned on by sliding out the keyboard.
Is it normal? or is it something to be fixed?
I have an ATT Tilt with stock ROM.
(just got it few days ago from ebay).
Thanks.
Down with new, weird "features"!

If I read your sarcasm correctly, I am in agreement that this is a dubious feature. I think there are a number of changes from 8125&8525 to "8925" that are questionable. I wish HTC would spend more time getting the hardware and basic features working perfectly, and less time adding new programs just to change the look.
Transflective . . .

Everything I can find in searching says both the Hermes and the Kaiser have transflective screens, (as well as the 8125); e.g., from elite-electronics.com RE: the Tytn II: "color transflective TFT". [However, neither the 8125 or Tytn II have the technology that allows good viewing in daylight, like a Garmin Nuvi 350 or similar]
But if you can actually see something on screen on the Hermes when backlight is turned off, then that is truly different from the 8125 and the Tilt.

This is normal behavior. If you don't like it...download KaiserTweak.
Under the Keyboard->Slide Wake option you can disable it.

Agreed. HTC - stop fixing what isn't broken in the first place.

Transreflective is NOT in the HTC TyTN II spec but is in the TyTN I spec. You can't believe a reseller.
If you turn off the backlight on a Hermes and then grab a big flashlight and shine it on the screen, you can then easily see the screen, the brighter the light the better you will be able to see it.
If you try this with Kaiser you will quickly see that the bright light will make it impossible to see the kaiser screen, no mater what backlight setting you choose, and certainly not on low.
It's a simple test and I'm convinced on what I say.
That said, the Kaiser's transmissive screen is super bright in most mid to low light areas since transreflective screens are normally not quite as bright as transmissives.
It have happened to me 3 times already, and I've only had my Diamond for 3 weeks...
When I leave my device charging over night, in the morning the display looks completely scrambled / distorted and the only thing I can do is a restart... Luckily it boots up normal again.
Am I the only one with this issue??
Btw... I've handled my phone with care & not ever dropped it or had it near any moisture, I guess this might be a harware issue!?
Dun worry owziee....
I having the same problem too.........
nothing but a white static/scrambled screen, right? Happens many time to me...the only thing i can do is re-insert the battery (holding the power button to restart doesnt work).
what about soft reset button ?
Sof reset fixes it. I think that the 3D chip is overheated, because it happens when I play sensory overload (a 3d game) too.
But strangely not when I play Call of Duty 2...?
Alteast we could get it back to normal with a soft-reset, kaiser had similar problem where only a hard-reset was possible after the same situations i guess..
Regards,
Carty..
i had a similar situation after i used my device to send a text, turned the screen off then turned it back on immediately, i had some strange screen with all different coloured pixels and it looked broke as hell, but i merely just pressed the power button on and off and it was fixed again :S
Yes i have the same problem and have no idea what is causing it. The most frustrating thing is when it happens my alarm does not go of... I would realy like a fix for this.
phew! It has happened once with me, and frankly it scared me a bit. Removed the battery and then it was Ok again. Weird behaviour. I don't think it has anything to do with heat tho.
I had the same issue too and I had to perform a soft reset fer it to work but after a week the touch screen of mine stopped workin no idea why i had to give to the service center fer repairs they told me it wud take a week to repair it rite now I am without a diamond
Something like the screen shots below?
I've had this problem for quite a while. If you disable Touchflo3d, you will not have this problem at all. This issue only concerns the 3d gpu.
I've since updated to v1.93 Olinex SPL and its more stable now, thou I still get it once a while, especially after a long period of not touching the phone (e.g. when sleeping).
I haven't seen this posted anywhere so I figured I would post for anyone having a similar issue with their One.
Recently my phones backlight stopped working. It would not work at boot or in the ROM. I tried flashing to stock and tried optimizing the proximity sensor, but no luck. It was clearly a hardware problem.
Not seeing any solution to this issue other than people saying it is the screen or the motherboard I decided to order a new screen.
Well installed the new screen, still no backlight. I was about to give up on it and just buy another phone, but I got the feeling that the light sensor may still be my issue. The backlight on the capacitive buttons would not turn on unless I helded down the power button to force shutdown. This meant the backlights for the buttons at least worked and something else in the phone was preventing them from turning on.
I decided to remove the light sensor from the daughterboard (opposite the power button connector). Booted it back up, and the screen came right on. The phone works great without it, other than auto brightness. The screen still turns off when against face during calls.
So long story short if your LCD and button backlights aren't working don't order an LCD or rule your phone dead right away. Open it up and take out the light sensor, it could be the culprit.
I'm going to order a new sensor and can update with results after installing if anyone is interested. In the meantime I'm using the phone without it, no hiccups so far.

hey
i'm having the same problem are you sure that it is a hardware issue and not the software issue my h/w buttons doesn't light at all and my screen stays black for some time after unlocking the phone it comes back but the brightness is too low
any suggestions would be appriciated
Mine was a hardware issue, the backlight did not turn on at all, even on the htc start screen. The capacitive buttons would only flash when holding down the power button. If ypurs is intermittent and your phone is rooted you cantry insralling an app fhat alows you to change the proximity settings, sorry, cant remember the name of the app i tried. If the app can't detect the sensor it is likely broken like mine was. If that doesnt work try a different rom.
If neither of those help it is likely a hardware issue.
i used the app both light senor and proximity sensor are working fine
any other tips that i can try

Sorry for taking so long to respond, just noticed your reply.
Did you ever get it working? If a different rom did not solve your issue maybe your sensor is just dirty. You could try cleaning it with a can of compressed air. Not sure how effective it would be, but it may help.
Hi @nsodmordex, my HTC One M7 is in the same situation as you describe, no backlight, but working. I'm going to try your suggestion of removing the light sensor, but I'm unable to find it, I'm not sure where the light sensor is.
Please, can you tell me which component is the light sensor? This is a photo of the daughter board:
htt ps://d3nevzfk7ii3be.cloudfront.net/igi/ALPJIMWqGsLwul5Y.huge
Thanks!
Found it... it's located behind the daughter board, at the two little holes of the front cover of the phone. I have removed it but no luck, the screen continues black, but the mobile is working good.
it seems a screen related problem, I'm going to try to change the screen and see if it comes to life again.
Drain battery
Hi all,
I also have this problem and found out that if I drain the battery completely and wait about 1 hour, it turns back on when I put the charger in the phone, if the screen doesn't turn on, drain and wait longer, if it does turn back on then power the phone. Do not wait till it has a little bit power because than it fails again and you must drain and wait again.
It works for me and I will make a video of it and post a link later.
Hope it works for you all!
Tip: use a led flashlight to see what's on the display
Ps. Stock m7

Than the lightsensor is broken, are the contacts on the back of the sensor 100% clean, in my case it was dust that created the error.
Is the display not broken?

The display is ok because I can see what is on the phone with the LED flash of a Galaxy S2 so I think that the display is not broken.
The backlight doesn´t turn on with the light sensor and without it either. But i can remember that the last time that it worked the Autobrightness was fine
Edit: I tried rebooting on fastboot and recovery via ADB and the screen is without backlight too
PD: Sorry for my English

In my case, if it worked it was ok also the autobrightness.
I think the sensor is broken and if you replace it the backlight comes back on (sensor is +- 10€ in holland)
Just give it shot
Have you tried the battery drain?
Hehe my english is also not very good

But as I read, if I remove the sensor and turn on the phone without it, will it work?
In this moment the phone has 0% battery and if I plug the charger i can see the red light and if i use a flashlight, i can see "the battery with the lightning" on the screen

No i dont think thats gonna work, push the power button (whitout charger) every time till the battery is really empty, than wait an hour.
If you connect the charger and the screen will not turn on, wait longer. a night is even better.
If the screens comes on then turn direct the phone on dont let it dim itself or else you can wait again.
This worked in my case but my lightsensor was dirty and after a cleanup it worked normal and it stil works.

Okay, thanks, it worked once, but with the phone turned on and the backlight working, if the screen turns off, the backlight runs away again.
can you repeat point by point what i need to do?
when you say "drain" the battery, you mean leaving the phone on till it turns off? then what should i do? wait an hour and plug the charger to see if it works right? okay, and later if the phone turns on what i need to do?

By 'drain the battery' i mean continuously turning the phone on with a empty battery till it does nothing, not even vibrate.
It must be so empty that the phone not knows its a phone.
And yes if the screen comes on just power it on, thats it.
1 drain
2 wait
3 plug in charger
4 screen comes on
5 turn phone on
6 done
1 drain
2 wait
3 plug in charger
4 screen stays off
5 drain and wait longer
that are the steps that worked for me
Thanks @Dippie83 , it "worked" draining the battery and waiting forma a night to turn it on but when i turn on and i push the power button yo lock the screen, the backlight stops working
Any idea?
Dear all,
I've bought recently Mi5 and received it couple days ago, unfortunately I have a serious problem with the lcd. It's really bizarre malfunction, I don't have problem with backlight or touchscreen and I can use the phone normally but the moment it goes to sleep or I press the power button lcd goes dark and it won't turn on. Button back-light shines but the lcd is essentially dead and I can't do anything. The only way to wake it up is reset. If I set the sleep option to "never" I can use the phone normally until the battery drains but it's really awkward and inconvenient. I've been trying to update the rom, wipe all data etc but it didn't help. I even flashed the newest rom V8.5.3.0.NAAMIED via miflash unluckily the problem still remains.
Any ideas?
