Works for 3 minutes, then quits.
My A1121 works perfectly for the first 3 minutes m/l, and then it stops producing sound. The volume indicator light shows orange when I use the + or - volume buttons (after it quits). I am using AC power and the mini RCA jack. If I unplug it, and wait some time (at least 30 minutes), it will play again for about 3 minutes before the problem repeats.

@curt2023 post some good picture of your power supply as well as your other boards (crossover) with your Question. Yes, it could be bad capacitors but it can also be bad amplifier IC's. Adding images to an existing question
