Question about Sony STR-DE675 Receiver
I have a cable connecting my Sony STR-DE675 to an airport extreme connection (which is connected to a printer and plugged into the wall) to play iTunes on the speakers connected to the receiver. It worked in my previous home, but now the speakers cut out every few seconds, PROTECT doesn't come on the receiver (and I've moved the speakers thinking they might be too close).
PM44.1 is on some of the time when this happens.
I am using an optical cable to connect the receiver and the airport connection.
Any suggestions on how to fix this (do I need to use a different cable, move the airport? move the receiver?)

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."

Your unit being stuck in protection mode is an indication that its having a power problem. Remove its plug from the wall and fix it back into the wall, then turn it on again. If its still stuck in protection mode, then the power supply board in the unit is the cause of the problem. The receiver is trying to avoid further damage, that's why it is on protection mode. Its protecting the receiver. This was how the manufacturer programmed it.
The power supply board might be defective and maybe that's why the unit is on protection mode. Its receiving power but it cannot transfer the current to the necessary part of the unit because a capacitor, diode, etc may have been faulty. Until these bad components are replaced, the unit might function.
To actually find out what's wrong, you need to disassemble the unit with a screw driver and check what's wrong. You will be needing a meter in order to test the components on the power board, once you detect any bad component, you can make necessary replacement at any electronics accessories store withing our vicinity. This is the only way by which you can detect the problem.
Of course, testing the power board with a meter will require someone that has the ability. So it you can't, then you might be needing the help of a repairman or you can call a friend that has the ability to help you out.
I wish you the best of luck.

I didn't look up the schematic for this exact model, but many of these units have the surround amps on "cards" just like a computer has a video card or network card, and these can come unseated in a move. Open up the unit, and reseat any cards that are in the unit.
You can check fuses while you're inside the unit as well.
