Screen unresponsive, partially dead

So I've got a relatively cheap used sensation off ebay. It was announced defective and it was stated that part of the screen is dead. So I thought there were some dead pixels which didn't seem much of an issue for me. However, there are no dead pixels, the screen looks fine. However, it is very unresponsive. I have trouble pulling the ring to unlock the screen, selecting icons, typing, ect. There is also one part of the screen (one whole row) where the screen is completely unresponsive (doesn't react at all when touched).
Tried the SGS screen booster, tried cleaning the metal contacts on the battery side of the phone... nothing worked. The phone still has it's warranty seal, so it doesn't seem to have been opened..
Any suggestions other rhan faulty digitizer?
Thanks for your help
Sounds exactly like a faulty digitiser, which is costly to repair unfortunately, although it it surprisingly hard to break them, recently smashed the glass on mine, and the touch still worked perfectly!
I just asked the seller what made the touchscreen to stop responding. He said the phone fell off, hit the ground and afterwards the display wasn't working properly. Maybe there is some other way to fix this? The digitizer itself is not broken.. maybe there is something that got displaced.. or maybe there is a faulty connection somewhere on the pcb... do you have any suggestions? Thanks!
just noticed that if I squeeze the phone top to bottom (i.e. grab it with the thumb onto the unlocking latch for the back cover and the middle finger on top of the phone, just above the speaker) it opens 'messages'.. So maybe there is some bad connection on the pcb? Or should this definitely point to a faulty digitizer?

Small row of screen unresponsive

I have an Lg G2. Works great.
Yesterday I noticed some weird behavior. The screen was finicky and hard to use. The screen is cracked on the two left corners of the phone but the display area is perfect. The picture looks perfect...
I decided to open up an app where I could draw and it turns out I can't get any input on a perfect row about an inch or so from the top of the screen, and about half an inch across, all the way from one side to another. I can color in the whole screen but it's perfectly blank on that one row.
I did some research and figured it might be some loose connector with the digitizer.
Is this possibly an easy fix?
I have warranty but no insurance
Thanks!!!
Bump
Check the connectors
You cant really cause anymore damage by just checking the connectors going to do that when i get home tonight, I'll tell you if it works

[Completed] Screen is black and touch screen is unresponsive

Hello, I dropped my phone a while ago (a couple months) and it cracked the screen allot but the touch screen and lcd/digitizer were working with no issue.
Recently i dropped it again but this time on soft carpet and the LCD and touch screen are not working anymore, the LCD isn't cracked at all. The LED light at the top works and the back and menu buttons work fine.
Help?? plz
There's nothing anyone out here can do to help you for physical damage. You need to either have it repaired or purchase a new device.
Thank you

Strangest screen problem I've ever seen. Would this be a broken displayor broken GPU?

Hi all
My moto Maxx has gone through a lot, but the strangest problem yet started yesterday.
As you can see on the attached video, half of the screen is constantly scrolling. This happens in fastboot and recovery mode as well, so I'm pretty sure it's a hardware problem.
The digitizer still works perfectly, and registers touch where the icon or button should be positioned on the screen. The moving screen also does show everything correctly, just in this crazy scrolling way.
I'm not very hopeful in fixing it, but was wondering if anyone has ever seen this, and if you guys think this is a broken display(and any way to test this?) or a broken GPU. If it is in fact the display, I might consider replacing it.
Some background on all the terrible things I did to this phone:
- Dropped it and cracked screen in September.
- Replaced the glass myself, slightly burned display when removing glass without any consequences (just a tiny mark on the top right, the side that actually still works).
- Dropped again, broke glass again, never bothered to fix it, some small pieces are missing so dust, sweat,.. could've gotten int.
Video:
Most likely the display being broken.
Even when my tempered glass protector is missing chunks the screen starts to funk up. Only worse being the real screen especially the digitizer.
You might be right pjd, or at least screen related.
I opened it up yesterday evening, and I think it might be the cable connecting the screen. Depending on how I positioned the screen and thus the angle at which the cable was bent, it was fixed, the same, or just completely black.
The only thing I have to try to find out now is if it's the kabel, or the connector on the motherboard. Any suggestions on how I could test that are welcome!

Screen Replacement leads to blank screen

I have a Blu Studio Energy (D810U, I believe). I went to a lot of trouble getting a ROM that had the fewest bugs, but once I did, it worked well until I lent it to a "friend" who promptly smashed the screen. Not just the digitizer but the LCD as well.
I ordered a screen replacement and swapped out the screen. I've done this before, so no sweat - at least until I turned on the phone and found that while it was reading touch input and the backlight was on, there was no picture on the screen. It responded by vibrating when I pressed the capacitative keys on the bottom, and when I pulled the screen slightly out with a suction cup the edges of the LCD were lit up. I removed the assembly, replaced it repeatedly, and finally bought a new screen assembly and put that in. Every time, I had the exact same results.
Does anybody have any idea what's going on here?
