Screen issues after replacement - Xiaomi Mi A3 Questions & Answers

Hi at all,
my uncle's Mi A3 had cracked screen, so he told me to replace it with a brand new. I replaced it the first time, and after some time the screen became useless because of bad lines (green, blue, yellow) all over the screen that didn't let you do anything. So I gave back the replacement screen to the seller that sent me another one of it. Tested it, mounted it and now after a week the same problem. Now the phone has been shutted down because of low charge, this morning i tried to charge it and now it works well as usual. What the f*** is happening? bad screen replacements? Did I do something wrong each time I replaced it?
Thanks a lot to all who answer.

seller has good display??
checkup ur mainboard too.

[Q] Replaced LCD flashing Red Light.. Comments?

Hey Everyone,
I have managed to destroy two Atrix's. The LCD was broken on the first then wifi/bluetooth just failed on the 2nd. While changing the LCD's I managed to crack the good one putting the phone back together.
I ordered a replacement from RepairsUniverse ($87.98CA) and it took two weeks to show up. I put the phone back together yesterday and I'm getting a flashing Green light. At first I thought the battery was completely drained so I left it for about an hour to charge. I would than get a flashing red light with a white flash in the middle than more red flashing. I'm sure it's telling me something here.
I did have the new LCD show an image but it was so dark that you could only see it if you reflected the light off the screen a certain way.
I have put the original LCD in and it will boot and show a picture (cracked obviously) so I don't know what the issue is with the new LCD. The part numbers on the cable are identical so I know it's the right piece.
What now? RMA or is there something else to try? Kind of pissed about it. I've been using a BB Curve 8530 and it's the biggest P.O.S. Can't stand BB since I made the switch to android

tell him to return it back to the shop he got it from for repair or replacement
It's not software bug, I'm pretty sure.
Something broken inside, and it'll be great if they don't need to replace the dispaly, because it's a bit too expensive.
This happened to my old Samsung phone. *Not an S3* Just had to open it back up and one of those weird square thingys for the display was partially on.
Definitely seems to be a hardware prob, maybe the display got damaged. Only option is to return to the shop for repair, or if lucky a replacement .

[Q] Should I replace my phone's motherboard?

Hey guys!
I have a GT-i9300 for about 2 years now. Long story short - last year I bought a liquid air refreshener for my car which leaked out and without noticing it I just threw my phone in it and later on reallised what had actually happend. So fast forward 1 year later, the phone is till working though not fully. The lower part of the screen turned green, about 3-4 cm has a gree hue on top of the content( if it turns on actually, sometimes it does not turn on ). When I turn the brightness higher it gets a bit better, still not fully. The touch functions absolutely normal.
So I opened it and checked the motherboard, it looks weird and has a few small "bumps" arround the chips . I tried removing them but it didn't help ( it might be just some sillicon, I don't know ). So I was thinking would replacing the motherboard help? I found one that is from exactly the same model and has the same memory size, could that help me with the display?
Thanks in advance!

Sounds like your motherboard may not the problem here. I would suspect the lcd. You would need to replace the lcd,digitizer and glass combo.

Touchscreen not working

Hello all,
First of all I hope I am writing in the correct section... Otherwise please let me know.
Secondly: Something really strange is happening to my Galaxy S2.
Last year, the glass broke on the street and I changed it manually by buying one from eBay and following video instrctions. This year the touch and AMOLED part of the screen cracked (I don't even know how). This time I decided to buy a Galaxy S4, as I didn't want to "invest" anymore on the 2-year old smartphone, but I kept it. Later this year I decided to fix the S2 one again, and so I ordered a replacement screen (which costed a whopping $105!!!) and changed it. To my surprise, although I checked all the motherboard connections more than twice, the phone turns on, the Welcome Screen (configuration for first time usage screen) appears, but... The screen is unresponsive and I also can't change the volume nor turn the screen off by pressing the lock/power button.
If someone knows something about this problem or how to fix it, I would appreciate a comment with information regarding it to be able to understand what is happening.
Thanks in advance!
B.S.: I don't know if this information has anything to do with the problem, but the first screen I bought wasn't original, as it didn't have the Samsung logo on the ribbon cable, while the new one is original and the Samsung logo appears on the ribbon connector. I wonder: Is this a factory failure?
@joseguse
Thats what happest when u buy cheineese sh...
Buy ORIGINAL screen for I9100 and replace it. Thats all.

Touchscreen ghost touches(screen flickering)

Hey guys, recently I had my Z2 sent to a service shop because it wasn't turning on or charging. The guy at the shop said that it was the battery fault and he changed it, but he also told me that the screen was not working( flickering, ghost touches, unable to work on it). So he put my old battery on and when I went home the phone actually turned on and booted up, but still I had the screen problem. So whenever I touch the screen it doesn't respond and it touches by itself. Tried putting it on rice for 20 hours, dried with a hairdryer and assembled dissamssebled the screen jacks, still the problems wasn't fix. Do I really need to change the whole LCD or is this a problem that can be fixed?

Yes, you have to change the screen, or more precisely, the digitializer.
But since the LCD and the digitialier come in one-piece, you have to change it as a whole, but at a much lower price, as your screen can be sold again and recycle the good LCD panel.

So replacing the LCD would fix the problem right? That's great then because I found an LCD with a very low price (20$), completely new on ebay and I sucessfuly dissassembled the old LCD out of the phone. I'm gonna buy it as soon as possible. Thanks man.
