That’s what I figured - but after watching a couple of repair videos on YouTube and checking what they checked, I’ve discovered that one of the mosfets on the 12V power rail has gone, and on the console in the video that had caused the entire 12V rail to short to ground, so if those capacitors are on the 12V rail (which I’m pretty sure they are) then that mosfet could be the cause of everything. So I’m going to replace that first and go from there. Just waiting on the parts…
