Rockford T15001bd In Protect

[RJohns777]

Working on a Fosgate T15001bd. No shorts but protect light is on. No rail voltage. No shorted outputs. Anyone have a schematic?

See attached.

Is the protect LED brightly or dimly lit?

 

[RJohns777]

Brightly lit. The +15V supply was being pulled down to +10V. Found U201 was pulling it down. Replaced U201. Not in protect now but no audio. That's all I know so far. Heat sinks are running warm, not hot, but no audio out.

BTW, running 100Hz signal in with 4 ohm load.

U106 Was also bad killing the audio. Thanks Perry for the schematic.
