Sorry if my original message was not clear about this part.

I tried the new T-CON without the pin blocked and it doesn’t work. It has the exact same issue than the original T-CON: relay click when turned on and another relay click 3 seconds later.

I haven’t watched the lines with a magnifying glass. I wouldn’t have the knowledge to tell what’s going on. If I zoom in the closeup photos I took, I can see the lines are actually of the right color, but brighter. That’s why I originally thought the issue could be the T-CON and wanted to give it a try, because it...

Does it work even if T-CON is sending the SOS signal?

That’s great to know for the future. Thanks!...

I haven’t asked but it was probably from a cracked panel, seller was selling only some spare pieces. But in any case, the new T-CON didn’t solve the issue. So it must be the panel, it would be really weird if both T-CONs have the same exact issue displaying vertical lines in the middle. Also everything that I've read points to bad panel when having vertical lines like these.

These lines appear only when blocking the SOS pin in the lower LVDS, so calibration won’t help much. There must be a short in the panel like Diah said....

Thanks, that's what I thought. I blocked the pin during only a couple of minutes to see what was going on and reset the main board to factory settings (to remove personal information). I promise I won’t use it with the pin blocked 😂...

Hi all! I'm learning so please be patient with me.

My LG OLED55BX decided to not turn on anymore after a bit more than 3 years. I've read the forum quite a bit and have done some basic troubleshooting, but I’m stuck and need help with the next steps.

Symptoms:
I turn on the TV and hear 1 relay click. Stand-by light blinks, light can be seen in optical connector, no image on screen and 3-5 seconds later another relay click sounds and TV turns off.

What I've tried so far is:[LIST][*]Disconnected lower LVDS cable -> Optical connector light stays red,...

Hi all!! I'm constantly learning, this time taking the opportunity of my dead OLED to keep learning new skills.
