Middle of touchscreen not working. - LG Optimus 4X HD

Hello all,
Its been few weeks since I have that problem on my 4X, the middle of touchscreen is not working, and my 1 year warranty is over, I will replace the faulty part by myself but I don't know if the problem comes from the touchscreen itself or the motherboard.
Here is the problem (you can see the touchscreen zone not working):

}

I think it is hard to say unless someone had the exact same problem...
Based on my modest experience I assume that if mobo was faulty the screen wouldn't work at all
and/or would have also other problems rather than just that
To me it personally looks like changing touch would solve, but it's pure guessing

I agree with @Rudjgaard here. Based on guessing, I think you need to change the touchscreen.

Help! Kaiser screen loose!

Ok so the other day I dropped my Kaiser a couple days ago and now the screen feels really loose when the screen isn't open. I don't think anything cracked inside.
Is there any way to fix it? I'm thinking about opening it up to see if there's anything I can do. The phone still works fine, but it's bothering me Has any one else had this problem before?
Thanks
Duct Tape can do wonders.....

Same issue here, feel my LCD loose. Any solution ?
I didn't drop it and i only bought it less than 2 months.
take it back.
So I opened it up today and found out that the loose part was the sliding part here: http://www.pdacenter.ru/images/htc_p4550_kaiser_060.jpg
Is there anyway to tighten it?

Maybe it is a hardware based bug?

Faulty touch screen
I have a touch screen fault also. Could you try drawing vertical and horizontal lines in note (or similar application) and see if it has the same effects as the attached image.
I would also like to know if there is a fix, ie new touch screen.

"brighter" spot on the screen

Hi,
After months owning an N1, I managed to sell it today and buy a new one (with a guarantee this time) for a little additional money. The problem was, after some time using it, I noticed there is a small problem with the screen: there is a spot near the bottom left corner which seems to be brighter than the rest of the screen, especially when holding the phone in a certain angle. Kind of like this:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Do you guys know why this could be happening? Anyone has something like it? Is there a way to fix it, or should I send it back to HTC?
Nothing? :-(
Does it have screen protector?

Part of digitizer dead?

Is it possible a part of the digitizer to be dead? I didn't know if the problem was because of the rom, and after installing a new rom I realized that the lower part of the screen is dead. Both capacitive buttons and a part of the lower screen isn't responting on my touch. Here is an image of were the screen is dead. If I change the digitizer will it be ok? Or it may be something else?

I have some similar problems with the digitizer...
My digitizer has lost function in the middle-part.
so i changed the digitizer with a new one.
then the problem was gone for 4 month and now there is the same problem with the new one again at the same place.
so i think the problem could be somewhere else like on the board itself...

some user on reddit /r/androidwear had another issue with a few dead pixels but other than that i am not aware that there are major problems. i don't have them, maybe some solder got lose or something who knows.
Hooray!)) I got to solve the problem with the screen.
It was not a dead pixel.
The problem is hidden in the loop connector, sealed-off contact on the ground.
Was poorly soldered connector, now everything works fine and does not flicker))
