Re: LG OLED55C6P-U Turns on, vertical lines, then turns off.

And one more thing again. If I unplug all of the tcon cables going into the driver board EXCEPT the far left cable, the set will power up, and stay powered up, with colored vertical lines in the same spot as the white ones before, and also since it isn't shutting down like this, the main board seems to properly power up, because the optical audio out LED lights up red. However I cannot test for audio out of the speakers, as it will not respond to the remote, I can't even turn it off with the remote (or the main button...

Also, I forgot to mention, but it has 3.5v standby when off, and 12/24v steady when powered on.

Hey guys. New here, but have been a long time reader. I originally posted this in a different OLED repair thread, and was given the suggestion to try starting a new thread, and I agree. I got this LG OLED55C6P-U TV on craigslist for cheap as not working. Seller stated that after a lighting strike during a storm (which we have been having lately in TX) it stopped working.. An hour later. Which tells me it probably wasn't lightning damage if it worked for a little while after (I could be wrong).

Once I took off the back cover, I found some sticky red stuff that looked like maybe one...

Well update: I was definitely grasping for straws lol. Guess it helps to test it first before posting about it. Yes when the set is powered on, the 12 and 24v pins do in fact show correct voltage, so much for hoping that would be a problem lol.

Re: Just picked up a 55 inch LG 4k OLED for $50!

Yeah, I am inclined to agree with you. I was unaware of the possibility of water damage until I got home and opened it up unfortunately. But, that is the gamble I took lol, couldn't help myself.

I did notice that I am getting zero volts at all the 12 and 24v outputs on the power board, but I am getting 3.5v at all of the standby pins, not sure if the 12 and 24v pins are hot when the set is off like the 3.5v ones are. I am grasping for straws at this point probably.

Hey guys. New here, but have been a long time reader. Not sure if I should create a new thread on this, or revive an old one. Probably going to revive, as this thread has helped me a bit already. I am in a similar position that OP was. I got this LG OLED55C6P-U TV on craigslist for cheap as not working.
