G2 Possibly Needs New Motherboard Or?

Hi guys..

So I bought a LG G2 used on eBay. It was for 50 bucks or so and it was cheap because it didn't have a screen but the seller stated everything else works.

So heres what I did:
Purchased new screen x 2 (twice)
Both screens didn't work
Connected phone to TV through an HDMI adapter
The phone heats up while it's booting up sometimes

I can see the phone screen on the TV but the screen doesn't light up at all except it does have a tiny bit of backlight. As I touch the screen, it goes VERY slow, takes a second or two to respond.

How do I know if it needs a new motherboard or just new parts?
If it goes very slow but it shows on the TV, does that mean the motherboard is the issue?

Thanks in advance!!

Phone is pre-rooted after motherboard replacement

Hello friends.

My D855 had to go through a motherboard change. Before this situation, I was using my phone with a stock rom. It had to go to warranty and when it came back it was rooted. SuperSU was loaded and SU binary was installed. Is there a necessity for the warranty to do that? Or is it the motherboard that arrived was rooted? What is the logical explanation for this?

Touch screen works only when I press motherboard

Hi, I've got a problem with my S3 LTE. I have changed full set in my phone. Connected it to the motherboard and there is a problem with touch sreen. Once it works, then it suddenly stops and doesn't work. I tried to change ROM, I have contacted seller of set, because thought that is faulty. He sent me a new one and it is the same problem. When he got the package with that first one, he wrote to me that it works perfectly with his phone. After few weeks with this problem I saw something new today. At the time, when I'm pressing motherboard in red selected area, touch screen works! It is not about the LCD flex, because when try to push this flex it doesn't help me. It works always when I press here, like on image. What is an issue? What could I do? (sorry for my English, it is not perfect)

Here on this picture it is i9300 but it's the same place as in my i9305.


Thanks!

[Q] Changing the motherboard can fix a hard brick?

Hey Guys.

Changing the motherboard can fix a Moto G hard bricked?

One m7 motherboard swap

Hi, so recently I stuffed my One m7 during a battery replacement. I damaged the ribbon plug on the motherboard that connects the touchscreen so now my touchscreen doesn't work.

My device is a 2014 international HTC one m7 in Australia. Unlocked bootloader, rooted, custom ROM Android 5.0.1, custom kernel and Xposed. I haven't been able to locate a replacement board using the part number but I have some options for motherboards on eBay.

However, I can't find an international/AU board. I have found some T-mobile and Verizon which I assume are UK and US?

On close inspection, some of these boards are visibly identical so my question is - can I order one of these identical boards and fit it to work with my device? Thanks

Help! Nexus 7 2013 repair failure! Broken motherboard

So last night i dropped my tablet and the screen had cracks all over it, well i watched a bunch of tear down, and screen repair videos on youtube, then tried to take it apart to fix it myself. But when i tried to remove the silver motherboard ribbon cable, the white connector broke off of the motherboard. :crying: :crying:

Note that warranty expired several months ago.

What should i do? is replacement motherboard and screen assembly worth it?

Screen backlight only after replacing motherboard

Hey folks! My Nexus 5 recently broke down and it seemed motherboard was damaged (i checked it via diagnostics tool). I replaced it and everything seems to be working fine, except screen is not showing anything. Weirdly, backlight is working! Phone itself is working too, I managed to unlock it and flashed latest firmware, but it didn't help. I also tried to reconnect screen flex cable, but it didn't help either. Any help will be much appreciated!

I attatch two photos of backlight working.

Bad motherboard?

So randomly a couple of weeks ago my screen just stopped working. Whenever I turn it on or wake the screen white and green flashes. I've reset it to stock, and tried just about everything else I could. I just got my new digitizer in the mail thinking it was that, and it doesn't work. I know the phone is on because I can see the notification light flashing. I'm not sure what else to do but return the digitizer and try replacing the motherboard. Is this what could be it? Could it be something else? Thanks.

[Q] Replaced motherboard, now it's not charging!

Hey everybody! As the title says, I replaced the motherboard on my SM-G920V with one from my wife's old S6 (also 920v). She thought it'd be fun to throw it at me when she was angry, and shattered both front and back glass. BUT ANYWAY... After I finished installing everything how it's supposed to be, I started it up and was so happy to have my S6 back to OE2! My only issue now is that it won't charge, yet will recognize a charger. I haven't been able to connect it to a computer, because mine was blessed with a lovely RootKit/netbot that took over every aspect of my machine. So if any of my hardware people could help me out, that'd be great! What could I have done wrong?!

*Ripped off antenna from motherboard*
