MB issue
take it out from tv... and measure at the socket resistances value reference to boards chassis point... or replace it... to me it sound BGA issue...

So you are confident panel, BL, TCON and PSU are all good yes?

Other board I actually tried to heatgun the BGA but made the problem worse.

So sorry but which socket pins to measure resistance? All 28 of them? Look for short right?

Yes, the main board is bad. I mentioned this in post #6.
I had this exact same tv and fixed with new mainboard

Yes this was the consensus but after replacing twice with E-pray boards and having the same problem I wanted to be sure.

i am not master..... all users are Master include whom didn't joined your threat,,, as it refund agreement for yours MB you have, i would go with any TV size from 6350 series . other things if it run and you have display screen at any matter or issue.. it can be adjusted with e-z adj menu.

by the way did yours tv worth such huge investment ..? or u plan to sell it later

if i am in yours place will repair the MB .. repairing MB never being difficult if you do know how to read value and using DMM

so if you are ready to repair the MB.. start with high resolution photos from top and down side after removing the metal heat sink

Re: LG 70UH6350 (UB.BUSMLJr)

Yes, that board will work. But that price is steep.

Actually I have a board EBT64174323 on the way that cost 140 $USD shipped so not bad (but shipping $$.) It should arrive this week.

As far as investment it is mostly stubbornness. It really bothers me that a TV only lasted 3years and with almost no parts available and would go in garbage. So with you guys helping me I will be most happy to get it back on the wall. I will have 2 X bad main boards leftover; I would like to troubleshoot them as a project if possible but I think BGA's are toast.

Re: LG 70UH6350 (UB.BUSMLJr)

Re: LG 70UH6350 (UB.BUSMLJr)

well the first thing is see if the compressor is still kicking on.

Re: LG 70UH6350 (UB.BUSMLJr)

could troubleshoot the fridge right here, but theres a member whos little mind gets confused and starts complaining, maybe open it in the appliance section.

lol thanks! Yeah I'll spin up another thread. Every 5 years or so the water line coupler fails it seems (pretty high pressure in this building.) So woke up to a lot of water on the floor. My guess is it found it's way through the back cover and into electronics. I have no light/no sign of life. Will check the power boards fuse I guess

Re: LG 70UH6350 (UB.BUSMLJr)

I see, hopefully the fuse popped and there's no damage.

That is funny so like you were saying... there is a sealed hatch at the back for the PSU but open it up and out pours water lol. So it sealed the water inside. Fuse is good though so will blast with alcohol then have to test components I guess.
