Hi Diah,
Are you referencing testing these input voltages from PSU rails to TCON? (See image)...

Thanks Lotas, I figured that out, the connectors are still secure and function, just the little tab thing broke at the top....Leave a comment:

Thank you Diah, I will check those with multimeter and respond to the thread with results.
I have also ordered replacement FLEXIBLE FLAT CABLES 41P/51P for connection from mainboard to TCON but they will not arrive for a couple weeks....Leave a comment:

Re: Sony XBR-55A8G 4K OLED image ghosting/jumping around
I uploaded pics of the front of the mainboard, any suggestions on getting these ribbon cables out? These are the only two I could not get, I don't want to break them.
I will upload pics of the back once I get these out, thank you for the help so far....Leave a comment:

Do you think replacing the mainboard would fix this issue? Or mainboard and cables?...Leave a comment:

Sony XBR-55A8G 4K OLED image ghosting/jumping around
Hello All,
Hoping one of you wizards might be able to help me, I'm new to TV repair, I'm trying to troubleshoot a ghosting/jumping image on a 4k 55in Sony XBR-55A8G OLED TV.
I have tried re-seating all cables, and lightly manipulating the cables while the TV is on to see if the picture changes with pressure on any of the cables/connectors. I also replaced the TCON board and the ribbon cables connecting the TCON board to the panel, the issue has not changed with the replacements or with any cable manipulation / re-seating.
I saw some people had success... -
