How to fix LG G4 that just killed itself. Plugged in and no charging screen or light

[Android Central Question]

I put my phone down on the table and left. I came back and pressed the power button and it did nothing. I thought that was weird and held the power button and it didn’t turn back on. I then plugged in the device and still nothing happened. No charging LED or charge screen or anything. It is just black. I took the battery out and held the button for 30 seconds and put it back and plugged it in and nothing. I got out my USB volt meter and noticed that it is drawing power from the charger but the screen isn’t lighting up and the charge LED isn’t lighting up for whatever reason. I put in another battery I had laying around and nothing changed. Is this phone just dead or is there still hope in recovering it. I have no idea why it killed itself for no reason. Any ideas to try that can fix this?

If you plug the phone to the computer does it recognize it?

Welcome to Android Central! Unfortunately, the motherboard might have died. The G3 and G4 were notorious for various motherboard issues that would cause bootloops or outright failure.

^ I had both, and both failed in that way, alas. The G3 lasted about 5.5y, the G4 failed much sooner.

5.5 years is pretty good for any phone, to be honest.
