Hi
on the mainboard do you see any electrolytic capacitors that look to be bulging(electrolytic capacitors look like tall cylinders)
Thanks:-)

@nmpp post some pictures of your power supply etc. with your QUESTION. That way we can see what you see. Adding images to an existing question

I'd change all the electrolytic capacitors anyway. They are cheap. They don't need to be bulging or leaking fluid to be the cause of the problem. You can measure them properly with a good ESR meter, but it's better just to change them all, even if just one is giving problems.

@automotive I agree with that. My concern is just that there is more going on with that board. I have had plenty of issues with bad MOSFETS and traces on speakers
