        Check q530 for cold solder connections, or shorted. Also could be open c512 4.7mfd open and check coil L517 for overheated and shorted.

              Not sure your problem but did find this if it's a shutdown problem. REPLACE C517 "A" BOARD. OPEN AND 60 CYCLE GETTING IN THE 13V LINE THAT TRIGGERS THE SHUTDOWN ON. 470MFD 16V.
