screen scrambled after digitizer replacement - T-Mobile LG G2x

So I replaced my digitizer, and after reassembling the phone, now the screen is all scrambled, as in the picture. It actually reacts to touches so the new digitizer is working. So did I connect something wrong, or is the screen just broken? Anybody else got a screen like this?

Looks like the lcd is shot. Maybe it just needs to be reconnected, give that a shot first.
When I was replacing iphone screens I've had similar occurances with a poorly connected cable.

You need a new LCD screen too.

I've ordered a new screen. I've tried taking it apart and reassembling again, but the screen came up the same.

I have a parts g2x that did the same thing, I can take the main board out it and use it in another. So it's definitely screen/lcd related.

[Q] help with t-mo g2x screen/digi

Hi
i bought this used g2x and when i got it and powered on there are lines going across the screen is this a Digitizer issue or a screen issue so i can replace accordingly.
i took pictures of it if it helps.
the screen responds to finger tap so i guess digi is ok.....
Thanks in advance for your help.
I would deffinately have demanded my money back. Well, its going to be the lcd screen. there's good and bad news here. Good: will be far easier to replace than the digitizer. Bad: from experience, the LCD costs more. I think for my last phone, the LCD was slightly twice the cost of the digitizer.
The reason its your screen though is because the digitizer is only conductive glass. It doesn't produce any light in which you would get those lines.

If you bought it through ebay and the faulty lcd wasn't described as a problem, you need to file a report so you can get a refund and prevent it from happening to others.

It is possible that if the seller repaired the LCD that the ribbon cable connecting the display to the logic board shifted and came loose during transit.
Contact the seller before you do ANYTHING... first try to get him to replace/refund, if they won't, find out if they replaced the screen or digitizer themselves. If yes, you may be looking at simply reattaching a cable.

[Q] Need new LCD for Sensation 4G....does it matter which one i buy from eBay?

Hi All,
I have checked the forums and tried finding the answer to this but haven't had any luck. I was putting on one of those "military grade" screen protectors on my wife's Sensation 4G last night (the kind that you apply water to the back of and then place them on the screen). Long story short, the screen works now (after putting her phone in rice overnight) but the screen is fairly dim and it flickers a bit. I know I will have to replace the LCD portion of the screen since that's the only part that got some water on it from the screen protector application.
Question is, does it matter which LCD replacement screen i purchase from eBay? i have read a bunch of threads that the digitizers are specific and may not work correctly if you get the wrong one, but does that hold true for the LCD itself or can we simply buy any new LCD replacement screen from eBay and install it on the phone (the original digitizer will still be used since the touchscreen works fine).
Any help would be greatly appreciated...i feel like a dope for causing this by applying a screen protector, even though my G2x didn't have this problem at all after applying the same screen protector from the same seller.
Sorry for bumping up an old topic, but I am interested in this too. Anyone can shed light to this matter please?
OP: Did you end up replacing your LCD? How did it go?
So hey you where installing a zagg screen protector?how much water did you put on the screen?

I still think those water application screen protectors are a ridiculous idea. Who's idea was it to use water on electronics?! Normal screen protectors do just as well. Make sure the lcd screen is the same physical size, pixel density, made specifically for the device, etc. Try pick the most reputable seller. But you WILL notice a difference in the screen, either colour, sharpness or response.

[Q] Replacement Digitizer Problem

So I finally replaced my cracked screen and I've been having issues with my new digitizer. It's one of the LG digitizers, not the ones that say T-Mobile at the top. When you touch the extreme left side of the screen, it acts like you're touching the extreme right side of the screen at the same time. It's very weird - when I try to capitalize, it also backspaces, and my a's all have l's after them - stuff like that. It's like that all the way from the top of the screen to the bottom.
I got in there and cleaned a couple of specks of dust that I had accidentally left between the digitizer and LCD screen and it didn't seem to help. I used compressed air to clean the contact where the digitizer ribbon cable connects to the motherboard and tried to get the ribbon cable itself to sit under the motherboard nice and straight (I had a little trouble with it the first time and it could have been crooked, I guess, but I'm not sure if that would even matter.) I've also tried soft reboots, removing the battery, full wipes, and even have experimented with a few different ROMs. Acts exactly the same.
What do you guys think? Do I have a bad digitizer or is there something else I could try to get it to work properly? Thanks!
I buy broken phones of Craigslist and fix them. I have put digitizers on 4 g2x as of yet never had that problem. I'd make sure the connections were nice clean and seated correctly. I see you've done that so my conclusion is that you have a faulty unit. Run a calibration app and see if that helps

I had bought a digitizer with the LG logo on it and it was not as senseative to the touch and as well when touching the left or right sides of it where off a little. I used the ones with the T Moble logo and all works like new.

Hi, my screen cracked, so I got a replacement digitizer and installed it. When I reassembled the phone, it worked fine, except the buttons at the bottom (home, back, etc.) and the bottom 15% of the touch screen do not register. The rest of the touch screen works fine.
Do you know if that part is connected differently from the rest of the phone? Or any other reason it might be broken.
This may be dumb on my part, but my package didn't come with adhesive, so I used superglue. Could that be messing up the sensor somewhere? Or is it not likely that?
Any thoughts/comments would be greatly appreciated.
You probably got some glue in the wrong place. I used 3M double sided adhesive, that way I could be exact with the placement

Superglue + Electronics = BAD!

Hah what he said.
You should never use glue of any sort on electronics. If the manufacturers don't do it, then you surely shouldn't.

Ruined my phone :(

Hello my beloved community... today I screwed up, and I hope you can forgive me.. I was going to the pool and had my Shift wrapped in my towel.. walking down steps it dropped out and landed on concrete and well.. you can see in the pic :/ I'm not sure how my phone contracts are doing right now and whether I can get the One anytime soon or not, but for the meantime I'm using a Samsung Intercept, ikr kill me already. The reason I'm not using the Shift is not the cracked screen. That doesn't bother me. Was even thinking about replacing it, the problem is, which you may be able to tell by the pic maybe not, is there is lines going all across the screen from left to right, similar to a tv's static, if I slide out the keyboard halfwayish it goes away, but all the way and it comes back. It makes the phone unusable. And idk if it'll be gone even if I replace the screen. Somethings telling me its the flex cable, maybe loose or damaged? Idk I wanted to get your guys' input. What do you think?

Digitizer perhaps you can always pull it apart and check tho
stare into oblivion
Fall into sleep
I'm no expert but it might be the display. I have a non cracked but not fully working digitizer (there's a spot in the upper left corner not responding) and display I can send you if you want.
Well the Digitizer is smashed up big time. You could replace just the Digitizer, and hope all is good. But after doing this process a few times. I would suggest replacing both the Digitizer, and the LCD as an assembly. Also, once you have the Shift apart. Make sure to inspect the Flex Cable thoroughly. If it is compromised, I would replace that also before reassembly.

[Q] Screen won't turn on

Hello and thanks for reading this. First, a clarification- I'm under the impression that the front of a GS3 is the "front glass," with the digitizer underneath, and the amoled screen underneath that. Forgive me if I'm wrong, but that's how I'll refer to them below.
Yesterday I attempted to replace the broken glass on my GS3, and found that not only was the glass cracked, but the digitizer was too. I got the glass off, but managed to crack/warp the digitizer in the process. I'm sure there's no damage to the amoled screen, maybe a couple of light scratches, but now the screen doesn't turn on. It was working fine that morning. Now, the screen does absolutely nothing. LED functions fine.
The phone will vibrate/LED will light when I get a notification, and I have 3 batteries all at 100% charge. So I (think I) know that it's just the screen components that are messed up. Do I have to buy the $150 assembly? Or is there an easier, cheaper (!) fix? When I get home tonight, I'll try download mode, removing the sim, but I'm not sure if I want to reflash firmware yet. Thanks for any ideas.

The amoled screen is directly under the digitizer. However if you break your digitizer, there's no way for your phone to respond rendering your amoled screen useless anyway. It's essentially one unit because of the way it's manufactured.
Why would you reflash firmware? If you replace the entire display assembly it'll fix it. Your issue isn't software related.

I don't know how Samsung designed it, but I would think the amoled screen would still light up and show stuff, even if the digitizer's broken. As for flashing, it's a suggestion I found through Google. I was sure it wouldn't do anything, which is why I wanted to save it for last. Thanks for the relpy.
