VSX819H amp wont enter service mode

Hi, My pioneer VSX 819h went into protection mode. It now won’t enter service mode. I’m following the service manual. The only thing it does is turns on for 4-5 secs when pressing power button+adv-surround which according to the service manual is used for clearing the error counts. Thanks

Until you resolve the protect mode, the amp will continue to work as you see it. Protect usually indicates that there is a short in the output section and the amp shuts down to prevent further damage. Since this amp uses discrete transistors for outputs, check each one for a short. Once found, change the entire pair (2SD and 2SC transistors) and any other components in the area that are effected.
