Happy new year to everyone! Health first, then everything else.

As for this board, I've been reading in forums that these could be "just" bad design.

Is there anything that I could measure/diagnose in order to see what is going on?
Honestly, I haven't got the board out yet, but I'll inspect it soon.

If is the (in)famous 820-3662 MLB, you can try to replace all FDMF6808 with new FDMF6708.
Don't waste time trying to find real "new" original chips; all of them are fake...

So to replace U7310/20/30 best is to use them from other donor board, is that what you're saying?

That is not the best solution.
You can got same issue too.
Buy new FDMF6708 from Mouser, or other serious webstore.

Okay, new 6708 installed. Before it would shut down every hour, now it is already on for several hours without shutting down.

Do you remove CPU heatsink prior to IC's replacement or you leave it on?
