So looks like my 6 year old OLED B7 is on its last legs. Started randomly clicking constantly and struggling to turn on. Reading online this points to bad capacitors on the power board?

LG and Curry’s don’t want anything to do with it. Annoying as the power board was changed as part of a recall by LG during 2021, so no doubt they cheaped out on the replacement parts and now I’m suffering the consequences.

Would replacing the capacitors be doable myself or is this not as simple as some make out? Alternatively is there anyway to source a replacement power board?

Thanks

A bit late to the thread but I had exactly the same issue, I also had the board changed under the recall.
If anyone has this problem it turns out it's the small black 12vDC relay switch which is at fault.
I replaced mine and all is good...a bit of soldering is required but cost was around £5 for the part.

Ah where did you source the replacement part from? I’m currently living with the issue and have been using a smart plug to turn the set on and off. Both Currys and LG have been unwilling to help.
 
Bah, so finally got round to swapping out the 12vdc relay linked above…. Still same clicking on powering on issue! Everything else looking ok, so unsure where to go with this now.

Yeah my concern recently is that the tv is now complaining that it hasn’t run the pixel refresh process for too long. With it being OLED I imagine the panel is going to get messed up without this.
