Thank you for the fast response. Odep-on, ioc-solid green with output on speakers. Sorry for the incomplete details.

if the amp is exhibiting any unusual behavior you need to disconnect the speakers and get it working perfectly on the scope then dummy load before putting speakers back on there.

[QUOTE=t0m]What is showing them all in "ODEP" mode?

If the ODEP light shows on the front panel this means ODEP is ready to use, not that its activated.

The light goes dim and then finally completely OUT as the ODEP kicks in.

Check signal through the amps.

i have a 3600 crown.when you turn it on only the signal lights coming on.no relay coming on either .what can be the cause?

Also before fixing, check VZ stage mosfets, are shorted surely.
 
Replace NE555 circuit too, and LM339 comparator.

I appreciate if you can re-upload the others ones pics about the parts we need to change for a PSU failure in the 3600 because yours link in the links are death too!

Thanks a lot
