SOURCE: Sony Receiver STR-DE310 flashing "PROTECT'

Replacing ouput transistors and probably a couple of resistors is best left up to a repair shop. The entire main board needs to be removed to access the solder side of the board, many screws and several connectors.

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.

No sound. It flashes protect.

Your device has went into protection mode, an internal malfunction causes it to shut down in order to protect itself.
Somtimes a physical reset will help.
Turn of and unplug device fro a couple of hours

How do i connect an ipod to my sony str-de310 receiver

Connecting to a home stereo
  1. For most home stereo systems, connect iPod to your amplifier's sound input using a 3.5 mm mini stereo to RCA adapter cable.
  2. Adjust the volume on iPod to less than half to prevent overdriving your amplifier. Adjust the listening volume using your stereo's controls.

    Note: Depending on your stereo, iPod may need to be set higher than half in order to get a proper volume through external speakers.

Sony AM/FM Receiver problem

I had a similar problem with my unit. I found no evidence of a short circuit and after removing the cover no evidence of burns or overheating . I turned the unit on and off repeatedly and eventuaully it started. As I was moving the unit back on its shelf I brushed my ring hand across the top of the unit and the "protect" warning started to flash. It occurred to me there might be a static electricity issue. I hooked up a ground wire as per the manual. Problem solved----at least for the past few weeks. The system has work flawlessly every time I turn it on.
