I have 0V on the ST - BY line not sure if the AMP has blown i have ohm’ed but not really sure if i have done it right any help would be nice forgot to add that it says check pow 5
Hi, Here’s the service manual for the receiver that may help. It is a direct download. Also don’t be misled by the title of the file i.e. MR7500 as the manual covers both models ;-) Try getting into the service mode (see p.9) and see if that tells you what is happening. If no good there are schematics in the manual. You may have to start checking at the power board and then move forward from there. Hopefully a start.
