when turning mda3 on backlight is working but the screen not - MDA III, XDA III, PDA2k, 9090 General

just get a mda3 with a problem
sometimes when i switching the phone on (power button) the backlight is working but the screen remains black so i can't se anything. the phone is working, i can browse the folders, i hear all the sounds but the screen remains black! after a while hes working again.
does anybody had the same problem? and how can i solve the problem?((((

have u tried a hard reset? ive never had this problem so i dont know, tho i guess if u sync with pc and save all all your wanted files and do a hard reset, it may sort it.

i've already tried hard reset, rom updating etc...
the problem is still there...((
i've switch "turn off the phone after 3 minutes" off, maybe it would help...
because problem was appearing most of the time if device was lying for 10-20 minutes without working...
update: nope, it's still black(

Think you have a bad device. A problem that is know is that the backlight will turn itself of (but you can still see the screen). This is some times the case with mine and I have the 1.40 rom, however I have had this problem with other roms so it must be some software that I use.

i'm also thinking so...
now i noticed that if you turn the device on and get a black screen, if you wait a minute he will switch the screen on. but why?

Boot problem

Hi.
My Artemis doesn't turn on, and doesn't even charge.
I don't know what has happened, it was in suspend mode, i pressed the power button, and the screen lights up all white.
I had to remove the battery to turn it off.
Now it doesn't do anything. I tried the soft and hard reset, but to no avail.
Is it dead?
PS: I left it without battery for a couple of hours, and it turned on, but then the screen turns all white, and it's dead again.
boot problem
Hi,
I have the same problem.
It doesn´t turn on and it doesn´t charge.
I don´t know how to flash the artemis. I can not enter in bootloader mode and I can´t sync it because activesync doesn´t work.
I remove the battery too but it turns off. I tried a soft and hard reset but
It does nothing.
any solution? please
Thank you
had a similar problem last month too. sent it back to htc authorised service dealer and was diagnosed with a faulty motherboard. luckily, it's still under warranty and they changed the MB. all functioning well now..
I've had five different motherboards and I'm still in trouble - I suspect there is a bad batch out there, as my original worked fine for about six months.... since then (its a long story.....)
Hy.
I have the same problem, can't even start by bootloader, sincer my batterry run out, i can't power up my artemis, any reason why ?
The battery is full .I tested on another artemis .
Edit: The only wrong thing I guess i did was flashing it to a touch rom, but it was all good till it run out of battery, if I sent htc to the warranty, they won't fix my problem because of the rom right ?

Strange problem involving power button, screen and soft rest

Ok, this is a slightly weird but VERY annoying issue..
Today I stopped being able to turn my TP2 on from standby.
What actually happens is when I push the power button, the phone activates, but the screen remains blank.
Pushing the volume buttons turns it up and down ( I can hear the tones)
Hang up and other buttons work ok.
The soft rest button does nothing.
Pulling out the battery restarts the phone, and the screen then works fine. Power button can then be used to turn the screen off, but will not turn it back on again
So long as I then keep the phone awake, all is well, as soon as it sleeps, I am back to the same situation.
Problem number 3 is that the Charging LED is no longer lighting up, but the phone is charging as normal.
I have hard reset the phone, and also flashed the latest WWE ROM from HTC, to no effect.
Charging LED is off even when the phone is shut down.
errrm...
Any ideas???

OMG, i am having the EXACT same issue. powerbutton will sleep phone but not initiate the screen to turn back on, openeing keyboard lights up the keys, closing lights up the buttons under the screen. Ive also hard reset etc.
Any help!?!?
I'm gonna try task29 and see what happens, could that be what caused it? Thats the only new thing ive donw
hmm, also noticed that when booting android, i get an error message: Something used micropkit_lcd_ctrl. This function should no longer be used.
Since the problem deals with the screen/sleep could this be a hint?
BTW: task29 doesnt help at all =[ cant anyone help?
Are you using Windows Mobile or Android?
Hard reset and see if the problem goes away.
running windows mobile and android. Cant boot into android because I receive that error message previously stated... Hard reseting doesnt help =[
Running WM, and I've done 2 hard resets and a ROM flash.
Interestingly enough, the last thing I did before having problems was to run up and play with the latest version of Android, using the cab install version.
Is there some code for that (perhaps used for the power button to intercept the press) that could be remaining in rom after the reset???
Clutching at straws here...
Ok, found this at the end of the Android thread:

thanks a lot, man!
this pretty much solves it - mines' also working now
Note: Flashing hard spl seems to have fixed mine too!
Hmm... could this HSPL also cause a problem with not connecting the device to PC? (device is not reckognized)
Hard SPL Reflash
Hey there, did you just reflash Hard SPL and evertything was fine? or did you hard reset and reflash your ROM also after reinstalling Hard SPL?
Thanks!
Michael

Thanks a bunch for posting hat here bbilko!! will try when I get home from my classes
Well i tried flashing the ROM, and hard rest but that did NOT work
Hard SPL on top of those did, someone else will have to test JUST using Hard SPL to fix the problem

I just booted up into my current rom(firestorm) and didnt let it sleep, plugged it in and flashed hard-spl, and it works now!! So dont hard-reset, just flash over your current rom.
Hmmmmm...
Just out of interest (as I'm always updating and playing with android) which version screwed with the phone?
Although it seems to be resolved, I'd rather not have to go though the bother of re-installing HSPL
I was using the cab install version
Project Android 031710v2.cab
Just to note further, before using it I had not installed Hard SPL, nor had I flashed my TP2 to any official ROMS

screen not turning off

my TP2 has stopped turning the screen off automatically. i don't know what triggered the change but the screen doesn't turn of automatically anymore after I use the phone, or if it gets activated in anyway (receiving an SMS, a phone call, ...). i check the settings/system/power and 'Turn off backlight if device is not used for' is selected with the time set to 30 seconds. however thebacklight never turns off. any ideas how to fix this? thanks much!

this happened to me a while ago as well, sadly the only way i was able to fix it was by doing a hard reset. but maybe someone else will know a better way to fix it.

thanks. a hard reset would be a last resort! i have many tweaks and too many apps to give up on easily. any other solutions out there?
I have the same problem but mine also turns on itself! When I turn it off with key it takes appr. 10 seconds and then it turns itself on. This does not happen all the time but when it has started I do not know how to stop it but it stops itself after a while. Soft reset does not help.
Have tried hard reset and then it use to wor a few days then it comes back. Very frustrating as it drains the battery fast.

[Q] Phone module off, touchscreen freezing, help!

Hy,
I have a big problem out of nowhere. The phone worked ok for more than y6 mths, while i haven't change the ROM. I found it blocked, not answering to any command, touchscreen or button. Soft reset it (red back-button) and it started but phone module was off, airplane mode on. I tried several times to switch them (phone, on, or airplane off) but unsuccessfull. Morover the touch screen is not getting any command but still the buttons work (phome, home, volume, midbutton). I hardSPL (OlixNet) and then installed a fresh rom (energy). the phone problem persists toghether with the screen problem which is appearing even immediatelly after starting up, or after 10 mins, varies. I also tried to disable the Sense, but same result.
ANother thing i have observed is that the battery drains very fast and the back low part of the device is getting warm after trying to use and few restarts..
I will try to give it an HTC rom to see if something's changeing.
Any of you had such issues with it? what should i do?
Thanks guys,

I could be also a cracked touchscreen in an early stage with a small crack, which happened to me.
Good luck!
Guys,
i too have the same screen problem,i tried changing various rom's still the problem persists.After new rom installation screen calibration needs to b done a number of times to finally start the mobile with home screen.
And then problem appears immediatelly after starting up, or after 10 mins. Touch doesn't respond correctly to my command instead it reads some other commands and finally gets stuck while other harware keeps working perfectly.
so, anybody could short out dis problem.......it seem to b a common problem to many people who keep changing there rom's frequently

[Q] Phone stuck in screensaver mode

Hi!
I brought my Xperia Play phone USED two years ago and I've never had any problems with it.
However, recently, the phone has started to freeze itself in "screensaver" mode (Where the screen goes black after 15 seconds and locks the phone), but the screen won't light up no matter which button I press. I've had to restart the phone every time this happens.
It's been behaving strange at start up as well, as it sometimes take 20 minutes just for it to turn on, while on other occasions, it won't turn on at all!
Is this problem caused by the battery, or is it the hardware?
Is it with stock firmware?

Yes.
I've never modded it or installed custom firmware/apps.
Have you tried factory resetting it?

Yes, but it didn't fix it. The problem still occurs.
tldr: Black screen, no display, everything works "under" (I can answer the phone etc). Not a flex cable problem because occurs randomly, regardless of the slider being open or closed. The problem also occurs during boot up, so rather not a software problem.
I think I have something similiar. Everything was fine until a few days ago the screen didn't want to unlock..or at least I thought it was that.
Basically the phone sometimes works OK but sometimes if I turn off (lock) the screen, it won't go back. To be precise, the phone works and if someone calls me I can pick it up moving the finger where the slider should be, it's just the display doesn't turn on. Same goes for booting, bootloader logo etc, so IMO it's not a software problem.
Strange thing is that it just randomly pops back, sometimes when I move the gamepad slider, sometimes when I put in a jack cable or if I hard reset the phone (remove battery). I've had problems with the flex cable in the past and this time I know that it's not it (no difference if I open/close the slider).
My guess would be some power supply or LCD driver IC issues, because the screen stops working almost everytime if I put the phone into the dock. Moreover, if the screen doesn't work, the orange charging LED is not working (green and blue are OK). The moment the screen starts working, the orange charging LED starts working too.
it's very strange but I'm used to electronics doing strange stuff. Just wondering if I should give a try disassembling the phone and trying to fix it or just buy a new one or something?
I might add that I have bought a new battery ~3 months ago, but it's been working fine to this point. I have tried if the same problem occurs with the old/original battery and it's the same.
well, any ideas?
edit: This video shows something very similiar (except the backlight): https://www.youtube.com/watch?v=m4p0-kv1cxA
Same problem. And I guess this guy has it too.
