Toggling power on and off is NOT a good idea, nor does it ever really fix anything.

Does the TV affect the receiver even if you have other sources selected or speakers disabled?

Establish if the TV connection or lack of it affects the problem by disconnecting one cable at a time (I have no idea what cables you use) to see if the self-protection is caused when the TV is turned On. Prove that each cable is or is not involved with glitching the receiver. If it still pops after the TV is completely floated from the receiver, consider a power surge as the culprit. Maybe you need to place the receiver on a power circuit that isn't shared with the TV.

Oh, btw, you're not drawing power from the convenience outlets on the reciver for anything that sucks up a lot of juice, are you?

Sony receiver stR se-501 found fuse burned after replaced turned on the flashing massage PROTECT come on . Did I miss anything?


Protect typically means that the fuse blew because something in your receiver went bad. It's now protecting your speakers from that badness. You need to get the receiver fixed or replaced.

I was playing some music pretty loud today on my Sony STR-DB790 and then no bang no crackling just strait to protect mode turned stereo off thinking nothing of it and now every time I turn it on strait to...


There is an output load causing the protect to engage, turn unit off and dis-connect the speaker wires from the back of the receiver, this will reset the processor ic. Now power on and turn volume right down, if the word protect stays off it means there is a short in the wires or one or more of the speakers. But if the word protect comes on with the "speakers and wires dis-connected" it indicates a short in one or more audio output ic's and will need a tech to address the extent of damage and cost.

It sounds like the output ic's may have failed, because of the complexity of system I would have a professional come and look at the unit for an evaluation, chances are he will need to take it back to the shop for service.

PROTECT DISPLAYED ON RECEIVER


This generally means you've got a short somewhere, and the received is trying to protect itself.

My suggestion is to disconnect all of your speakers at both ends, and reconnect them.

Most times this happens because a speaker wire is lose, and the positive and negative connections are touching each other, causing it to short out.

Stuck in protect mode


Speakers shorted out, blew a fuse. Replace the unit or (cross your fingers and) open up the box and find the blown fuse.

Goes immediately into protect mode


Yep. The wiring to your speakers or the speakers themselves have shorted out. You have a blown fuse. You'll need to either replace the unit or attempt to replace the fuse yourself.
