You know how it's said that no good deed goes unpunished? This is one of those stories.
I was updating a Marantz 2220 for a friend, new lamps, cleaned it up, the usual DeOxit treatment. It was working fine and I decided to take it a step further and recapped the P800 power board, as I had all the caps on hand already. Before I did that I checked the main filter and the two channel power caps. The main filter was reading 3230 uF on my ESR meter (should be rated at 4700), and I figured I would get to that after the power board.
After recapping the power board, there's no sound. Very slight power on thump. Unit powers up and all lamps work. Tuner meter moves when it reads a station. No sound out of the headphone jack.
I checked my work as I went, marked all the caps before removal, and they match the board polarity as shown by the old caps and also by the markings on the P800 board. Nothing appears to be backwards and no bang.
I reflowed the solder on the board, no diff.
Suggestions would be very helpful at this time. Anyone? TIA for reading this and and much obliged for any assistance.
