Polk Audio PSW505. I have replaced the shorted IC FET1A1, IRFI40189HG. And all of the electrolytic caps on the amp board. Then discovered ZD1 is also shorted. A schematic would be great or if not possible than just the zener voltage of that diode should get this going for our customer. Thanks for checking.-Carlin
No word from my post in troubleshooting channel of forum. Wondering if you can help. A schematic would be greatly appreciated.
