I have a sherwood rd-6513 it keeps shutting off straight after turning on. How can I fix this?

Its in protection mode ..
check your speakers cables first
if is all OK
then the receiver needs to be serviced the power supply section has a damaged parts or re-soldering the points again , but mostly damaged parts due to age of the device.
hope this helps
Kind regards

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.

Harmon Kardon Receiver "Protect" Mode issue

If your receiver enters protect mode with no speakers connected, it is an indication that you will have to start troubleshooting inside.This will involve visual checking and checking with a multimeter to isolate the problem. A further issue is finding out why your JBL woofer keeps blowing fuses. It could be shorted.

So what do i do if when i turn my onkyo tx-sv454 receiver on it says protect and then shuts off? How do i fix that or get around it? please help me....

I don't think you can fix it, unless you're skilled with electronics. Possibility that something has occurred internally with a circuit board etc so the system shuts down in order to protect itself from catching on fire etc. Get it services. Might not be too bad of an issue, but certainly not a bypass.

When playing dvd or or on video 3 playing a directv movie. Receiver keeps shutting off and the screen says protect. Seems to do it when the movie scene gets loud.

check your wires if there not touching behind the speakers and receiver. when it says protect this means something is shorting out or crossing over. one other thing it may be is if a speaker is starting to go bad. (please rate)

Onkyo tx-8211 protect

It's unlikely you can. Most hifi shops can though.

If you're still reading, open it up, and look for a switch of some kind. It may not even exist, but I'd say it's the best thing to look for when doing something considered mediocre at hifi shops (if it was difficult and interesting, they wouldn't find it so boring). Maybe it's a button. It will probably be labelled protection or reset or something similar.

So, look for a switch, or something similar. I have no idea where it would be because I've never dismantled such a thing. The other option (if you haven't done so already) is unplug it from the power and leave it for a while (overnight may be the best bet). This may fix it for you, and it's easier than undoing all those screws.

Cuts off and displays "Protect"

The protect light comes on when the amp cuts off the speakers to protect them from damage if something's wrong in the amp, or to protect the amp from speaker or wiring problems. If the amp plays for a while before cutting off, it's probably a thermal problem in the output stages. One of the output devices may be acting up as it heats up, or it could be bad connections that open up because of the heat. The trouble might also be caused by components in the power supply as well. Without having the unit on the service bench to check it, it's not possible to suggest specific things to look at. The manual wouldn't help you other than to say check your speaker connections and then have it serviced. The best thing to do if you want to keep this is to find a servicer in your area and get an estimate for the repair. Or if you or a friend is technically inclined, look into purchasing a service manual and see if you can do-it-yourself.

Problem with onkyo tx 919 unit

If you've had it "fixed" 3 times and the problem comes back either you have the wrong impedance (ohms) speakers connected or the power supply in the unit is the actual problem.

Happy new years,
