Has anyone had an experience fixing a power supply from the BAR 48 subwoofer? It clicks every 5 sec, output is jumping simultaneously from around 0 to around 3v. VDD is also jumping up to 14v and dropping back down. It looks like it tries to start but something is triggering protection on OB5269. I've changed OB5269 - no effect. Diodes look good, pulled out FET and checked - looks good as well. Capacitors look good. Nothing is visibly burned. I couldn't find any info on that power supply, even the output voltage.
