[Q] Screen Digitizer Dead Spot - Eee Pad Transformer Q&A, Help & Troubleshooting

hi all,
i recently replaced my cracked screen with a new digitizer, which is running the latest katkiss 4.4.4 rom.
the installation went well, but as you can see from the paint test i did (hopefully the image attached ok), there is a dead spot (in landscape mode) between x=650 and x=750, all the way from top to bottom.
anyone have any ideas on what it could be?
thanks!

[Q] A700 Ghost touches

Hi,
i have a courious Problem, mainly posting here in hope some have already opened up their A700 and know a bit more about the hardware.
I had to open up mine to repair the usb/Power port at the bottom. (no problems there now - and yes i was carefull while opening - i used the maintenance guide that was posted here for the A700)
My Problem now is: after I put it back into the case, I now have the following issue:
while in landscape no touches are recognized.
Landscape mode UPSIDEDOWN - most touches are recognized but with some ghost touches.
Portraitmode has issues as well.
First i thought maybe its some stress on the screen because a cable was pressed on it so i open up the device again and testet it without the cover:
without Cover:
i have some ghost touches in every mode (landscape, upsidedown, portrait)
i tested with the phone tester apk.
anyone has an idea what can cause this error? - since i already had the screen replaced very early after i bought it i'm reluctant to pay 300€ again for a new screen (since its unlocked...)
any of you hardware wizzards have an idea? could it be a broken connection on the digitizer/cable that i damaged by accident? Though i only opened the backplane and disconnected the usb/powercable from the mainboard and reattached it.
much appreciated
thanks
cheers

[Q] Screen Died - Can I resurrect?

So my phone screen will no longer display anything. No boot screen, no nothing. The software is running back there just fine, but I can't see it. Could this be a software problem (display driver got corrupted or something)? If so, would someone be willing to tell me the best way to reset? Is it more likely hardware failure since I see nothing during the boot?
My set-up is as follows:
Recovery: CWM v14.4.6
ROM: EMBRYO 6.10
Rooted, debugging on, titanium backup installed
Any help would be much appreciated.
I think I may have found my answer. The screen has been working intermittently today and sometimes appears tinted red, green or blue. Looks like it's time for a new piece of hardware :-/
For anyone else having a similar issue: screen stops working completely, works intermittently, displays with red, green or blue tint, or displays an inverted screen, my problem seems to be a loose connection with a simple fix.
I followed these instructions: http://forum.xda-developers.com/showthread.php?t=1540425 through prying off the back shroud (the one held on by 7 screws). I believe the screen connector is the one on the left in the picture, just below the power button (visible in the picture between steps 4 and 5). I disconnected this (gently pry up), blew off the contacts to try to remove any dust and pressed it back on. I then put a small rectangle of masking tape in the corresponding location on the plastic shroud (mine already had a rectangle of black tape in this position) in hopes that this would help keep the connector securely pressed against its mate on the board. Finally, I snapped and screwed it all back, and so far so good.
My guess is that this problem/fix probably applies to more than the galaxy s II skyrocket - possibly it will be useful to someone someday...or maybe not.

[Q] Touch Screen Unresponsive plus White Horizontal lines

Hey guys and gals,
I have nexus 5 that is just about a year and a half old. Every now and then, when I wake up the phone from sleep, the touch screen becomes unresponsive and I see white horizontal lines running across the top. I have tried restarting the phone, resetting the phone to factory. The problem still persists. The only way I get the lines to stop from showing up and get the touch screen responsive again is pushing down on the screen hard at random location.
I have attached a video of the problem I'm getting. https://youtu.be/CzgZ1bcN1Lk
I'm suspecting its a screen issue and I need to replace the LCD panel, Digitizer, etc
Any help would be greatly appreciated.
Thanks!
You need to replace the digitizer (if I'm not wrong), I've encountered this issue before on my older phone.

Half of the screen is black

Hello !
The bottom of my screen is completly black but the touchscreen is still working.
I went running with my phone in my hand and the weather was vert cold. At first the bottom half of my screen was flickering/grey and then it went completly black
What I already try to solve the issue :
- install TWRP and wipe everything
- disconnect the battery from the phone
Any thoughts ? How could I know if it comes from the motherboard or the screen?

No touch even after changing the screen

Hello,
I changed on my Shield the screen because i lost access to the touch screen.
So i took a screen coming from an old shield that was bricked by nvidia (battery problem), the screen was working before the brick.
I tried to make a system restore, i tried to install a new firmware from Nvidia server (the latest one) with fastboot and still no touch.
I wanted to know if someone had the same kind of problem and if the controller chip for the touch screen is on the MB or on the screen?
Do you have any advices?
Thank you.
