Strange problem with the screen. - Touch GSM General

Hi to all,
I have strange problem with my Elf. My screen stopped responding and I thought that the problem is the digitizer. Hard reset didn't help. I ordered a new one and changed it. Unfortunately the situation remained the same. So I got the same working phone from a friend and decided to change some parts to find out where the problem is. The result is..
My front panel(with the new and after that with the old digitizer) connected to the working phone - not responding screen.
My phone connected to the working front panel - not responding screen.
I have no idea what to do. If anyone can help. Exclude the warranty.

There is a small battery on the motherboard. Does anyone know its functions?
I have a suggestion that it is something like cmos battery of the PC.
My idea is to remove it for a while and make new hardware initialization.
I am not sure about that.
I doubt that there is something with the touch screen controller(TSC2046). Is there any way to reset it?

Screen problem

Hi,
I have got serious problem with my Hermes. When device is "cold" everything is working ok but after 20-30 minutes of using i got problems with screen.
It looks like screen alignment problem but i can't fix it with any known method. I have written simple application that shows me that top left corner is always pressed.
I have disassembled device to see if its really problem with chassis and its not. When i turn on device without chassis i got same problems.
I'm thinking bout buying new digitizer without LCD but i don't know if i could exchange it by my own.
How do i combine LCD with digitizer in Hermes? What tools i need?
Thanks for any help.

Dropped my Wizard - White screen

Hi to everyone.
I dropped my wizard and lcd broke so I bought a new one and put it on. The problem is that although it takes phone calls and it syncs to pc, the screen is always white with nothing written..only a white screen. I do not know whether another problem occured besides the broken lcd. I tried to disassemble and reassemble it again but with no success. Any help please?
Hi, If my understanding is correct there are 2 versions of LCD for the Wizard. Are you sure that you have the right one? I'm sorry that I am unable to offer any further advice except to say that if the phone 'phones' and 'syncs' the basics must be working. Also the white screen means that the backlight is working - the problem is the LCD drive. Perhaps worth checking with your replacement supplier that they sent you the correct part?
Good luck!

Screen Alignment Problem, New LCD Installed But Not got solution

I have MDA VARIO II. Once i faced a problem of screen alignment. I use my Keyboard(not on screen keyboard) a lot for chating and messaging. Someone told me to install new LCD becuase it is problem of LCD. I buy a new LCD from market to install. After installation, problem is still there. Pointer always hit to top right even i tagged bottom area. I did not understand the problem exactly. If it was a problem of LCD then it must be solved after new LCD but still there. Can some one tell me it is the problem of CASING or flex cable or something else.
yeah, it the same problem with me.
I have changed the touchscreen but it still same.
anyone can help?

sorry for my poor english

Screen suddenly died - Touch HD

Hi.
My screen just suddenly died, but I don't think it's a hardware problem, cause while starting it up I get vibration-response from it when touching the screen, but when PIN is asked the screen just don't work.
Any idea how I can fix this?
Thanks for any help!
No image at all + touch responses working = dead lcd display, but working digitizer. You will require a new screen module to replace it.

Hi and thanks for answer.
I get image and I get response on the touch until the PIN-code is asked, then the response goes away but the image is still there.
Any idea what might have gone wrong and how to fix it?

So you are saying the LCD is working, and the touchscreen is working?
Either your software is jammed or your touch-calibration is way off.
Either way, a hard-reset is the easiest way to resolve your problem.
There is no problem with the "visual screen", I see everything I used to see (so the LCD should be OK). It's just that it won't "recognize" or "answer" when I touch it, after a while.
I start it up, and everything seems OK. When "Windows Mobile 6.1" is shown the phone vibrates when I touch the screen. That means that it recognizes my touch, so the hardware should be OK. But when the PIN-code is asked, there is no feedback in vibration or anything when the screen is touched. The touch is just all dead, and the numbers I press won't come up or anything.
So, I think it's a software fail. I'm running one of Dutty's older ROMs, could that be a problem?
Can I flash it to another ROM with the "dead" touchscreen?
I tried to hard reset it now. Still the same problem, no response on touch.
The question : is it a hardware or a software problem.
Assuming it is a software problem - a hard reset would have solved it (since it worked before)
So the likely problem is the digitizer.
Yeah, it must be the digitizer. Is that something I can change / replace / fix myself, or do I need to send it to repair?
Thanks for help btw!

[Q] Replacing LCD and or Digitizer

Hey guys,
I just ended up with a g1 for a good deal. Only problem is that the touchscreen has a problem were it will shake back and forth between screens. I mean If im on the home page, and i slide it left or right to the other pages. It dances between the 2 for a couple for a seconds. Also I cant touch anything in the bottom right hand corner of the screen. So that brings me to my question. Since the glass is intact, that would mean that the digitizer is busted? As you may have noticed I really dont know. But if anyone could offer any help in my direction because I'd like to fix this myself. As Always...
Thanks in advance,
Lord CraiguS
Please i have the same problem. I would like to know thanks.
Same problem
As for me, this problem started when i`ve replaced the digitizer with a new one. It seems exactly the same as you described. I`ve noticed, that it dissapears temporary when i block the device (power button) and unblock it again. But sooner or later it appears again.
I suppose it is some internal bad contact in connection or in a flexcable of touchscreen.
However, not solved this problem yet.
Seems to be that i found a solution at least for my G1. I`ve installed a new CyanogenMOD 6.1.0-RC1 (i had 6.0.0 previously) - and the problem is not appearing for at least 2 hours!
I suppose it is somehow related with software handling of touchscreen taps.
