Hello guys

I have some spare time these days so I thought I would fix my SL1200 after I fried it while messing with the PSU.

The problem I have is exactly what appears in the video below

Now on a few sources I am reading that it is because of a fried AN6680.

Has anyone dealt with that kind of problem before?

I do have a spare PCB, but I'd rather fix this one, since I have it heavily modified.

Thanks for your time
