i have an sony receiver model str d 565 and i need tha code because its in protect modei have an sony receiver model str d 565 and i need tha code because its in protect mode
I dont Know If my Sony d565 is in protect mode or not ? but I replaced the fuse and it still wont work . It only has two orange lights light up and they are dimm ? so does that mean protect mode or what ?I dont Know If my Sony d565 is in protect mode or not ? but I replaced the fuse and it still wont work .

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.
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.
If the word "Protection" is not flash in the display when this happens, then the receiver is in a tight area where it can't get enough air and is over heating. There are temp senosors on the heat sinks where the output transistors are mounted, and they will shut down the power supply in an overheat situartion, but the protecting indicator shold flash. Blow some air over the receiver and see if that stops the problem.
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
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.
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!

Please see the sk1874. Remove the resistor 47kohm and test it.
