Blank LCD! - 8125, K-JAM, P4300, MDA Vario General

hi,
this is my first post. i have a major problem with my o2 xda mini s.
my lcd cracked so i replaced it with one i imported from taiwan (www.runpda.com).
the new display is blank but i know the phone is on because it responds to touch input. do i have to reinstall or flash the phone to get it to work or is it possibly a hardware incompatibility issue? any feedback is appreciated. thanks

U made a mistake...contact Kaiser Electronics..Mr Javed 9821160515

the first thing i would check is that the ribbon type cable that connects into the motherboard from the screen is firmly in place.. i had the same with my c500 realised the cable goes further in than you first realise.
Cheers
Steve

Touchscreen problem

Have a "small" problem with my touchscreen, it requires to be aligned every day,and by that i mean that the alignment doesn't hold much long...that means sms typing is extremely hard when you push one letter he shows you another that lays next to it .Is it due to the touchscreen or the system....i didn't do any ROM update i still have the original software on him:
ROM Ver.: 1.12.01 GER
Radio Ver. : 1.12.00
ExtRom ver. : 1.12.151 GER
Many thanks!!
i think it it the problem of touch screen
i think it it the problem of touch screen.after extrem use of touch screen its loes the alinement for this you replace the touch screen from your hardware guy.
Thanks for all
Hi i fixed the problem with a ROM update and i didn't install extra programs that i had before like ( Pocket plus or Calendar ++...... ), anyway now i don't have to align the screen. I don't know is it the ROM update or the additional software but the touchscreen is now working perfectly.
So if someone else have a similar problem don't replace the screen right away.
Thanks
it's hardware problem.
my xda mini also..
but i know how to fix this problem.
Maybe with you it was, my MDA is now working perfectly and i don't need to align my screen every day as i did before.That doesn't mean that all have such a problem,i am only telling you my experience with it.
Best regards from Vienna
Hello, in my magician is not everyday, hapens all the time that i turn on it.

Guys,
I've had that problem for a LONG time and today i finally got tired and decided to fixed it...here's how i've done it: You just need to lift a little bit up, a few small metal pins which are all around the touchscreen (see the picture in attachment). This will force the touchscreen to remain in place and will end all your problems related to touchscreen alignments.
Regards,
Keeper
so it does help? what do these pins do?
IS THERE REALLY NO SOLUTION TO THAT PROBLEM???
(* the pins have nothing to do with the touchscreen, they are what holds aluminum shell on the plastic chasis)
i had an o2 mini with 1.11 rom and its touch screen was not quite sensitive.. had to tap or drag stylus very hard..
but after upgrading to 2.03TX.. to my surprise.. my PDA now has very good touch screen response!

I tryed to re-flash rom or adjust metal pins but the problem persists.

Probably it's problem with flat wire that connects screen with mainboard.
You need to open yours xda, find that wire, unplug it from mainboard, clean its pins with alcohol and plug into again.
From this time mine xda doesn't decalibrating anymore

Hi
My cell also had the same problem. There is a bunch of wires coming from the back of touch screen, these wires fix inside a socket. There is a black color cover that fix the wires inside that socket. During mishandling that cover got loose, that's why your cell loose the screen setting. I fixed that cover and now my Jam works perfectly. (Do it if you have the courage to open your cell)

Hello, I just bought a used O2 mini and had this same problems. I finally found a quick way to restore the calibration that goes out every restarts.
Using resco registry editor, I found the data stored here->
HKEY_LOCAL_MACHINE/HARDWARE/DEVICEMAP/TOUCH/CalibrationData
So I make 1 clean alignment and quickly went and export the Touch key into my Storage. Now every time the alignment goes haywire, I just import the data back. Hope it helps.

Touchscreen is not working any more

Today, when I was switched on my Nike and tried to write my SIM cards password, I realised that touchscreen is not working. I tried to press various places of the screen but with no luck I made some reboots but again the same luck... so propably is not software problem. It's very difficult to use it only with it's keyboard and it looses its usability :S Is there anything I can do to fix it up???
Recently I came onto the same problem, at first the screen didn't work and then the screen just became black.
I opened up the phone and saw the flex cable had been scratched, so I bought a new one at ebay, replaced the old one, and wolah... worked like charm. Got my old phone back, installed a new 6.5.3 ROM and I'm LUVIN my "old" HTC.
Search for HTC TOUCH DUAL NEON 300 FLEX CABLE REPAIR LCD SCREEN US
I bought mine in Iceland, (Europe) but I think that all the flex cables are the same in all versions of the phone.
Thank you for your advice
Thank you for your advice,
I didn't manage to change the flex cable yet, because the touchscreen started to response again, but just for 3 hours... Now it does not response again. The screen now displays everything fine, but if I touch nothing happens. I can only use it by the keyboard. I heard that in most chases, scratched flex cable turns screen white or black, it doesn't affects the touch(screen). But I'll give it a go

dead display help

Thanx very much
You might be able to sell it for parts, got get a new LCD screen
hi,
do you think it's no possible a software problem(virus) ?
Tnx
Claudio
Welcome to forums
To discard that a hard reset should be done, but have in mind if it´s the screen problem that maybe you won´t be able to use it.
Good luck,
It sounds like most likely a flex cable problem. Flex cable and hinge can be purchased on eBay as one unit (the assembly makes separation impossible), however, there is always some danger that problem may be caused by the LCD itself or the mainboard. The only way to diagnose the problem is by process of elimination - to try your board in another working machine and then trying another screen in your device.
OK
I'll try
Thank you
I'm guessing this is your problem =] (oj)

Where could i purchase such parts, As i'm thinking of revaming my uni with a new case and screen bits as well as a new battery =]
- i've found a case for the vodaphone version which is sliver, but gives me a full re-kit : Screen case, Keyboard case, + Keyboard.
but tbh i really want a new full black XDA Exec (02) re-kit with the same parts
