Hello!
Your amps' output section is shorted and is sending it's supply voltage straight to the speakers. The protect circuit is there to protect your speakers from being burnt. You need to go to an authorized Sony service center. Good Luck!

Why is it blinking protect?


Try disconnecting all the speakers and turn it on if it still goes into protect you will need to get it serviced but if it turns on then you have a problem with the speaker or wire run (check for shorts )

Protect mode


I didn't see any mention of it in the STR-D565 manual, but on many other Sony models the "Protect" indicates a short in a speaker wire.

Why do speakers crackle and flash protect


Check your speaker wires. Make sure they are not touching each outher or back of the unit. This will overload your output transistors and shut down your amp.

I have rewired my receiver and the SOny str-d565 keeps shutting off. Is this fixable or should I just get a new receiver?


This unit most likely has shorted output transistors. The unit is entering protect mode which will prevent further damage to the unit. Expect a parts cost in the $40 range for this repair.

I turn it on and it says protect and wont play.


That model of receiver goes into protect mode when there is really
low
resistance or a short on your speakers/wires. It does it to protect the
final drivers in your amp. Does it do the same thing with all of your
speakers disconnected? If it doesn't then you might have a problem with
one of your speakers or wires. Check your wires for shorts in them
first. That may be the only problem. That model is designed for 8 ohm
speakers, but you can go down two 6 ohms safely. I have a STR -D865 that

has been running 6 ohm speakers safely for almost 3 years now. A way to
check your speakers out is to take an ohm-meter across the terminals on
them(with the receiver unhooked). They should read anywhere between 8
and 4 ohms. Check with the manual on your speakers to see if they
correspond. If the resistance is really low, you may have a short in
that speaker. it is also possible that if they are 4 ohm speakers, you
could have damaged the drivers in your receiver. I know the model above
mine, (the 965) has a 4-8 ohm speaker selection switch on the back. The
lower models were not designed to run 4 ohm speakers. Hopefully this has

been of some help.

Sony STR-D565 fuse continues to blow


You could have a shorted winding in the power transformer. The diodes in the power supply can be shorted. Filter capacitors can short and send power to ground which will blow the fuse.

"Protect" Flashing


In all likelyhood, one or more output transistors have failed. Please confirm your model as STR-DE335 and I'll post the probable parts that need to be checked.
