i have the exact same issue with a panasonic oled - i have no experience, only a cheap DMM / soldering iron and nothing to lose.

Some official repair shops were adamant diagnosing a screen fault - I could not accept that finding, as the screen looked fine.

So Diah is right (but I do not understand fully what he said): I got the t-con changed to an LED t-con (roughly similar) and the flicker was gone. Now looking for a definitive solution.

later update: got the t-con blindly changed (ie no eeprom copied), with a similar board. The TV works perfectly fine, image quality is 99% fine.

So you still have a 1% problem?

his 1% mean to me the same issue as before but it take long time to happen again.. just because the main reason he didn't change.. the 24V cable between PSU and T-CON driver boards or just replace it sockets

Re: Sony 65AG9 Oled Flickering

I was hoping that the socket with issues was on old t-con.

Yesterday, my issue was that the screen was slightly cloudly, visible only on grey.

Today, I have more issues. The TV is starting, then shutting down. If I repeat, it stays on and working, but the initial start-up has issues.

This is hard!!! I will be grateful for any ideas. Thanks

Smart person there, he starts with the easy stuff, if that don't work I would try a new tcon when having persistent flickering issue with oled: https://www.youtube.com/watch?v=cLtqS6a0DfM
