[Q] Should I replace my phone's motherboard? - Galaxy S III Q&A, Help & Troubleshooting

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.

[Q] Help Please With My Screen :( i9100

Hi,
I dropped my Galaxy S2 Yesterday (have no idea if this relates to it) But i plugged it into the charger this morning and everything was blue & some of the screen had turned black and some icons had burnt into the screen it looked like.
After taking it with me because it was still usable, Its not completely black except for maybe the faintest part of blue.
Im running Lite'ning rom, The newest one im pretty sure.
Just wondering if this is a virus? Or the screen is dead. I just cant see how it could suddenly die when it was flat and not turned on.
Phones not under warranty by the way. So maybe you could give me some options?
Thanks heaps guys
Probably the problem is hardware related due to the fall, but you could back all your data and try to do a factory reset to see if it fixes or not. If it doesn't fix maybe you should check your screen hardware.
Thanks for the reply,
I just reflashed Litening with Odin 1.85 and still nothing, I get the vibrations, touch lights, sound ect, But only occasionally a tiny little strip of blue along the top.
How would i check my screen hardware? Because i pulled apart my galaxy s after it died and accidently cracked the screen & Glass
How would i do a factory reset by the way? Since i cant see anything
I'd imagine it's dead. I'd take it to your local store and ask for an estimate on how much it would cost to fix it. If you can't see anything, then the screen is either broken or it got disconnected (or maybe some of the ribbons did at least).
Yeah, I just dont really wanna take the phone apart unless i know its likley to fix it.
When i first got it, I noticed it had black splotches on the screen in very dim light on a white background. Nd im guessing id have to almost buy a whole front screen assembly to replace the front screen D:.
Would i be better just to sell the phone how it is? Or repair it?

[Q] Touchscreen not responding

Hi folks
Just inherited a very worn out one year old Xperia X10 from my son. Been trying to resurrect it.
About 2 or 3 months ago the touchscreen started to become non-responsive occasionally. Admittedly, I didn't look at it for him at the time. Then he dropped it down the loo (think - hope! - there was only water in it at the time). We dried it out in the hotpress and it worked ok but still with intermittent touchscreen not working.
He got a Blackberry from Santa, so a couple of weeks ago I inherited the Xperia. The screen was cracked in several places and totally non-responsive. Rather than chuck it in the bin, I thought I'd try and fix it up. So I bought a new screen on ebay and the other night I dismantled it and fitted the new screen. Touchscreen is still totally non-responsive. There was a slight rust on the perforated metal plate at the back of the screen which I carefully cleaned with WD40. All the connections and circuits look ok. I've updated it successfully on both PC Companion and SEUS.. I've also tried flashing using instructions from this forum but cannot get it right (most flashtool symbols greyed out). I have a feeling that it's a simple problem but just can't get there. The screen display is fine, I can get the camera and the keyboard up using the buttons. But damned if I can get the touchscreen to work. I feel the problem harks back to when the screen was intermittent - it still worked after the water/screenbreak, but not that well.
Anybody got any ideas or should I bin it? (Can't seem to get any worthwhile advice on the WWW - happened upon this forum while searching and thought - "This is my MAN". (One suggestion I saw on the web was to try a new battery - can't see how this would make a difference, present battery working fine. Also, I wondered if the proximity sensor could be on all the time?)

Line on keyboard off calibration after screen replacement.

I just got done replacing my broken screen on my LG G3. I replaced the whole front panel and just transfered the guts. Everything checked out fine after replacement until i typed my first text message. row A-L will not goto screen unless I touch nearly inbetween the middle of the row beneath it. q-p work fine as well as z-m. What really has me boggled is that the screen accepts touches there in virtually every other app/drawing. Just the keyboards aren't allowing touch in that specfic row. any suggestion?
Found a few more bad section.. Pulled the back loudspeaker back out and tried reseating the cables and still had same issue. They're sending a replacement for free.
This was my first screen replacement, but not my first time dealing with small ribbon cables. All cameras function fine, hoping it was a defect in screen and not my screen changing abilities.. Any tips for the next one would be appreciated. Would like to have a fully functioning phone again sometime. This is nearly more frustrating than the broken screen.
I am having same Issue

Hey just curious if your issue has been resolved.... I am having same issue, but i took mine to a computer store i have been dealing with for years. about a year ago they started doing cell phone repairs as well. I had them replace my cracked screen on my LG G3 and that same row of text if off for me and there are a few other spots i have noticed are off as well .... very frustrating... Anyway the place I took it to has replaced 3 screens hoping they were getting defective parts.... they just called to tell me I can come get it but they were unable to repair the dead spots without going further into replacing boards or something.... I dont know... It is weird though cause you can get the dead spots to work sometimes by very lightly touching or just touching it in just the right spots like a calibration if off....

A review on G3 LCD's on Amazon reports the same problem "I installed the screen and immediately my wife mentioned that it seemed to have "dead spots" when she was texting / playing games. I noticed it myself when I tried texting myself as a test. Several of the letters on the keyboard just wouldn't register very well. She went into the settings and ran the "motion sensor calibration" test under general settings>gestures. This has resolved the touch screen issues. "
I don't see how that would fix it but I guess it's worth a shot.

Phone overheated a couple kf times and shutdown after this initially happened and consumed 2 full batter chages in minutes. Now the heat and battery problem is gone but screen still dark. Any ideas
Hi guys!
I`m having the very same problem. Back light of the main screen is gone, and it doesn`t matter how I adjust it, it is always dark.
Have you guys solved your problem already? Any ideas?

Having the same issue as of yesterday, been Googling possible reasons and it seems the 'backlight controller' has malfunctioned and the entire screen needs replacing (allegedly). Considering a new screen costs almost as much as the V10 itself on ebay these days I'm going to be trying to take mine apart to see if an easier fix is possible, it is more than likely there isn't, but I at least have to try. Let me know if any of you guys have any luck in repairing your phones

Update: Having replaced the screen with a new replacement screen, I am still having the same issue, indicating an issue with either the mainboard and/or the chipset. Can't really go much further with this it would seem so unfortunately I don't think the issue has any DIY fix...
Sorry guys... RIP my V10

I have Same problem,, Any solution ? please help me
My LG70 just did this for a few minutes
My LG70 just did this for a few minutes. Scared me to think my phone was dying. Restarted, still the same. While I was googling it, the screen came back on. Hope it stays that way. Really strange to take it out of my pocket and only have the screen lit in the upper right hand corner. I hope this wasn't a preview of things to come. Love this phone and want it to last!

Screen start flickering when in charge

Hi guys,
when my phone is in charge at 100%, after some minutes it start to flickering when there is at least an orizontal black line and a white part, for example if there are 2 notifications there is an orizontal black line that separates the two notifications, right? The white part of the notification start to flicker. I tried to hard reset and nothing changed, and also got my display replaced and nothing changed (huawei customer service said they will replace the mb, but idk if this will solve my issue).
Anyone have this issue or it's really a faulty mb ? I tried searching online but it seems that no one have this problem.
I'll upload later a video that will show my issue...
Have you dropped the phone? Even from a small height it could cause problems.
My old p10 plus fell out of trouser pocket and hit the inside of door panel but was enough to cause screen flicker.
I had a hairline crack in digitiser/screen.
It only showed when screen brightness was on low or if phone was cold.
Got the screen replaced and was ok after.

I dropped my phone only 1 or 2 times and always with protection, but even after the display replacement the problem didn't solve. It only flicker when it's in charge and already at 100% and when I unplug the charger, it stop. I noticed this problem only after I got my display replaced for the gluegate... but even after a second replacement nothing changed. I hope after the mb replace, my phone stops to flicker.
I have the same flickering problem with my Mate 20 Pro and have never dropped my beloved smartphone. For as of right now, the current (.232) update may have resolved the issue but it's only been a day since the patch. I will see how it goes.
edit: nope, even after the (9.0.0.232) software update, the flickering issue still remains as the original poster has described.
