Solved Sr7400 Shuts Of When Turned On Says Check Pow5 On The Display Marantz Receiver
Chosen Solution I’ve unplugged for three minutes and still won’t turn on. Hi, Here is a link to the service manual for your receiver. A POW5 error message indicates that there is a problem with the +5V DC supply inside the receiver. The service manual has schematics of all the boards allowing you to trace where the problem may be. Hopefully this is of some help. If you don’t have the requisite knowledge or tools to diagnose and fix the problem, I suggest that you contact a reputable, professional electronics repair service and ask for a quote to repair the receiver....
