SR7400 shuts of when turned on. Says check POW5 on the display.
I've unplugged for three minutes and still won't turn on.
Is this a good question?

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.

Plug iT out some longer try a hour or so.
If that doesnt work reset all wires.
Finaly my guess theres something wrong with the powersuply. If possible inspect your board. If something is loose you can probaly fix iT yourself if not take iT to your electronic repair shop.

Hi @@terrycotto,
Here’s the page in the service manual that shows the power board schematics. Looks like all the voltage regulators are there. Just find the +5V output on the connectors and trace the wires back to the appropriate regulator.
It may be easier if you download the manual so as to get a better view of the circuit.
