My wife's Williams Allegro digital piano powers up okay but first lost sound output to its speakers then recently lost sound output to headphone jack too. I suspect a simple component failure on the audio amp circuit board, which I might be able to fix with a little careful testing.
If anyone has a copy of the Williams Allegro digital piano service manual or schematic diagram it would be really helpful.
P.S. Any links to online articles about the basic subsystems found in digital pianos might help me to understand where to focus my initial troubleshooting.
Especially if it has block diagrams and maybe suggestions for basic troubleshooting test procedures.
I am psyched to try this repair as I repaired an LCD tv that I got off the street on garbage pickup day and still use it as my master computer display & entertainment tv. Repairing things and putting them back in service is so satisfying.
Thanks for any help or guidance,
Alan McRae
