Hello,
Have an unusual problem which is that I cant see the screen on my PDA2K even though the backlight is enabled and the brightness is set to maximum. This has been working fine and I havent installed any software recently. Is this a hardware problem or does someone have any other suggestions.
Holding on/off for 2-3 seconds does turn on/off the green and red buttons but the physical screen doesnt change. Same problem on battery or power
Any suggestions,
Problem was with a connection
Okay, Seems problem was a loose battery. Once I made the connection a little more snug, backlight came to life !!
Update: Problem still there, must be an intermittent wire thing, as sliding the keyboard up or pressing on the corner brings backlight to life. Guess I will be sending it in for repair !!
I have searched all over this board and haven't found a solution. I appoligize if this has been covered but has anyone figured out how to extend the keboard backlight timeout?
sorry,
but there is no fix for the 5 second keyboard backlight. It is done via hardware so it can not be changed.
I have a HTC pure mobile.it's brightness is very low.some times it's brightness going high and low.my technician said that problem is voltage to display on main board.I have replace a new display.but problem is same.now we need circuit diagram for check lcd backlight voltage to fix it.
please can anyone give me a circuit diagram for htc pure or Touch Diamond2 or have a other idea to fix it?
its is big help for me to fix it.
I am waiting for answer ASAP.
hello developement community!
i am having weird digitizer glitches where it detects 5 points which are there after some touching of the screen (usually swiping), it feels like a hardware issue most likely because i have had many roms and stock had the issue as well. the digitizer touches reset when i sleep/wake so it's not a phone breaking issue and i think the proximity sensor is always engaged which might be related. just wondering on some thoughts that might help. thanks in advance
ps, i had replaced the front panel on it and another s3 mini but the other has no similar bugs they both had the same replacement panel

Hi guys so the screen suddenly went dim and brightness wont work, opened up the back and used some pressure on the digitizer flex connector as you can see in the video here.

Now i'm wondering who's fault is and don't know if replacing the display will solve the issue.
What do you guys think?
I know when I have adaptive brightness on, my screen will do something similar to this where it won't go any brighter
Maybe try disabling Adaptive brightness?
