G68ADV

Manufactured: 2004
Date of failure: 11/2018

Unit blew the power supply while I was away on a business trip in November. My wife powered down and I opened up when I returned. Power supply was in bad shape, bulging caps and obvious darkening of the board on the power supply. I could see that several caps on cards and the motherboard were also bulging.

I installed a new power supply, replaced all of the caps on the motherboard and all recommended caps per the Meridian technical note 32 (including the 2 caps on the GOEA card). I adjusted the voltage output to 5.2V. Unit powers up fine, display is good, but no digital output and no relays (clicks) when switching sources or on power up like my other processors.

I replaced the remaining capacitor on the digital output card and the single capacitor on the digital input card. Still no sound. I also removed all of the cards and left in FICL, CD, EF, and GOEA for troubleshooting. No relays and no sound when using the calibration function on the processor.

Any obvious next things to try? I suspect some cards still have an issue, and am thinking the power supply failure did some damage. At this point, all of the capacitors on these cards are new- maybe something else was damaged?

Thanks for any advice.
John
