Question about Sony STR-DA7100ES
I am working on a Sony STR DA7100ES amplifier. Shotly after I apply power, the relay picks but then it drops out right after it picks. The unit continues to do this and the display stays dark. Is there a website with fixes listed for this unit?

There's a button that turns the speakers OFF right above the headphone jack.

Testimonial: "@dunnbiker Very true on assumptions! I've tried everything the manual suggests. Right now, nothing is connected to the unit, but upon power up, I get the SP:OFF display (which is not seen in the DEMO mode). I will try the headphone jiggling idea and see what happens."
