Decipher a software or hardware issue for touchscreen problems Solved !! - Tilt, TyTN II, MDA Vario III General

Few days back i had a problem of touchscreen not responding on my tytn2 and with help of this forum i managed (after few hard resets) it worked....now again it stopped responding....i suspect this could be a hardware issue (loose or broken flat cable connection,..) Before i go ahead and buy a new touchscreen i want to confirm from the gurus on this forum ..is there anyway to confirm that the touchscreen issue is hardware and not software...or viceversa.
cheers.
Edited : The problem ws traced to a connection cable betwen the LCD and the board. It was replaced and now th phone is working fine.

Keyboard problem - Hardware or Software?

Hi guys,
I searched and found nothing specifically related to this. I tried disableXT9.cab but it did nothing.
I recently broke the screen on my second Kaiser so I had to replace it with the screen from my first (which reception problems so I stopped using it). To do this I followed the guide posted in these forums on disassembly and successfully switch the screen. I sent text messages right away after I reboot my phone and the keyboard was working fine. A few minutes later a few of the keys had stopped working. The delete key didn't work. At one point it started to work again but didn't work anymore after that.
I figured it was a connection problem so I took my kaiser apart again and rebuilt it. Unfortunately it didn't work. I tried again. This time some more keys stopped working (not sure if its because of disassembly or not - my connections are perfect). It's possible I scratched the connection ribbon... so I replaced the keyboard with the keyboard in my other phone, but I still have the same problem.
Is this a hardware problem I can't fix? (if so why did it work right after I got it to work the first time)
Or is there something funky going on with my software?? Can I fix this?
Thanks!
I tried to flash a new ROM and the same keys are still not working.
I guess this means it's a hardware problem???
Does anyone know if I can do anything to fix this.. i already tried switching the keyboard...
i'd like to figure this out as well.. i don't think it's hardware as i've changed my tilt 5 times already by complaining about the keyboard.. is yours like mine where it works sometimes but not all the time?

Mega touch screen problems on x1

Hi Guys
I've been having some serious problems with the screen on my X1, most of the time now the screen doesn't respond to me tapping it, alignment is a waste of time.I'm wondering is there something I can do to fix it or will it simply be a matter of returning it. I'm in my last few months of a 18month contract and based on my recent experiences I doubt I will be getting another x1 (or even x2)
Thanks
Simon.
Exactly whats happened to mine! Its my 3rd X1 now and O2 cant (wont) fix it. Its a terrible phone. I cant use it now and you know what, I dont care, I would rather have a Nokia 6310.
Ive had every problem going and Im careful with my phones. First one the screen died when opening, second one no one can hear me and now this. I have also had the usual cracks issue on all 3 phones. Even when the phone works the reception terrible and it hangs all the time. Never a sony Xanything again.
Alignment problems and touch screen problem
I just updated my X1 last week ( 02/17/2010, my phone it's 1 year old with no problem at all, before this ) and everything was OK. Then on sunday the screen wasn't aligned, and I started to aligned almost every hour. Then I realized that after sliding the keyboard, the touch screen was death (not black, but doesn't work the touch function) for about 40 seconds, and after that it works again ( opened and Landscape). I also need to align the screen very often.
Before this happend, I never aligned the screen, only when I updated the X1. Also, on last friday ( before the screen problem ) I installed the Youtube aplication for the X1, and gave me problems because it doesn't have a Landscape screen, and the X1 crashed when I slide it, then I had to reboot it.
After this problem I started to have problems with my X1 ( alignments and death touch screen with keyboard opened )
Does some body have an idea to solve the problem?
Im sure this has to do with software or advanced settings like HKEY config.
Thanks in advance.
i have the same problem
but now, the problem is horrible

what could cause this problem
i flashed many roms, with same result
It's not something either of you installed, but your hardware - either your digitizers are on the way out or your flex.
its hardware
yes, i can say its hardware. I have repaired many of them now.
Most of the time when its black/no touch screen response its the flex cable.
somehow the cable damages very easy when opening/closing it.

Have try this?
1. Use a registry editor
2. Navigate to or search for:
HKLM/Drivers/TouchPanel/PressureThreshold
and
HKLM/Software/OEM/TFLOSettings/FingerPressure
(eg search on "pressure" and you'll find both)
3. Edit the values to any VERY VERY high value such as 999999999 (nine 9s)
*** CAUTION: do NOT change either of these fields to anything less than about 2000
because if you go low enough you will make your touchscreen unresponsive,
at which point it's tricky to change it back (learned the hard way)
Do I welcome aboard?
I have the same problem now and before I read this thread, I formatted my X1 cos I thought that problem was caused by software. Now I am sure it's about hardware. Have to open it soon
are you sure it's an hardware issue?
for me it started today after hard reset...too bad!
Well screen problems in Xperia are mostly caused due to the loose flex cable. Mine had the same problem. At times the screen would work and sometime the screen would not appear. But if you want to open your X1 and have a go at it yourself then do so.
I managed to fix my flex cable without causing any damage *phew*
If you have nothing to loose then give it a try and see if you get lucky.

[Q] [q] the rarest mysterious problem on xperia

I've been searching for internet for weeks and i still coudn't find the solution for this thing ..... my screen scrambles and jumbles everytime i connect to the internet using 3g....3dge.. etc but not wifi
here is my phone's background:
when i purchased it it has no problems at all...
after 1 and half years due to daily use keypad gets hard to press and the screen has a lot of scratches casing too..
so i decided to change the case of the xperia an the tft resistive touchscreen and clean the whole thing..
after putting it all back together it runs fine... checking the landscape camera wifi etc..
i decided to change rom because i think i could make it so new that even the os is changed...
i follow the basic process and it work fine..
after a week i notice that when i connect to the internet 3g... it jumbles the pixels of the screen in the upper part of the x1 even on landscape mode.. it is still there....
i searched the internet and i found old questions never been answered;;
http://www.xperiax1.net/x1-problems-issues/1735-youtube-videos-scrambled.html
http://forum.xda-developers.com/showthread.php?t=735531
somehow related to connecting 3gs..
i never change to 6.1 because of it's lack of features..
ive change 6.5 roms but the problem is still there....
here is a sample picture:

can somebody... please.... im begging you.... explain these problem with me and how can i solve it....???? PLEASE..... I APPRECIATE YOUR REPLY OR RESPONSE PLEASE!!!! thank you and God Bless!!!
PLEASE THANK YOU.... I REALLY LOVE MY OLD PHONE... I DON'T WANT TO BUY ONE...
dude, seriously. no one answered? it's very common tiling issues. yours just happend due the notification icons animation. most probable cause is vga driver. search for alternative driver.
No idea dude. But you may try to reflash your X1 to other ROM. I had been facing almost similar connection problem, but mine, the WiFi is undetectable. So I try to reflash my ROM with other ROM. Fortunately, it's working back.
this might be some app problem rather than rom/driver issue although some rom/driver handle it better. i just experience the exact issue after installing weather4me app. disabling refresh(update weather) during startup solved mine. maybe there's background app/process that doing something similiar causing it.
I see 3 possible reasons for this behavior:
- the displaydriver of the 6.5-rom is not really compatible to the hardware.
To check this you can flash the original rom and test if everything works.
- the radio interferes the communication between display and board.
This can happen when the device is not reassembled as original
(broken/removed shielding, dust/dirt in connectors while reconnecting,...).
To check this you have to reassemble the phone again.
- damaged hardware thru electrostatic discharge when touching the electronics.
Unfortunately this can not be checked or repaired. You can only guess if this is a possible reason by answering this questions to you:
- did you wear part-synthetic clothes while working on the electronics ?
(this forces electrostatic charge)
- did you discharge "yourself" every some minutes by touching a grounded point ?
- did you lay the electronics on a plastic ground ?

Xperia Z1 C6903 - Third Motherboard already giving glitches

Hello,
I have had two replacements of motherboards (done myself pretty perfectly) on my Xperia Z1 C6903 , purchased either from Ebay or Aliexpress. Both of them started exhibiting same behaviour after some usage (original one and first replacement), that they lose the touch screen/digitizer functionality. The LCD and Touch digitizer is perfect, however it refuses to work with the board. I have tried changing the flex cable an of no use. Maybe during the fitting of the flex cable clips there could be a damage to the pins on the main board. I still have the two boards with me and I tried cleaning and replacing them again and again but of no use.
It is surprising to see that two boards exactly ended up with the same problem. I have now got my third board and it is working fine for touch screen but giving me GPS troubles. I use the GPS regularly on my commute, however the google maps or sygic constantly keeps giving me a message of GPS signal Lost , intermittently and frequently . Have tried all known solutions of clearing the GPS cache from service menu and so on. H
Hence i need to know from the experts:
1. Is there a solution for touch screen problem to be fixed, maybe a software glitch (i didnt update the software anyways since I was using the last version of Dstrikerz ROM).
2. Any solution to make the GPS work stably, have opened and double checked all point/pins/contacts on the body and mid frame which supposedly could be the GPS antenna or cables.
Thanks for your help
