Question about Sony Audio Players & Recorders
Hi, Does it eventually power up? Check all your component (ie: CD Player, Tape etc) connections and especially the connections to the speakers. If you have any loose strands of wire touching the case it will cause problems.

Testimonial: "Hello, thank you for your interest :-) In fact, everything is working fine after several minutes. It seems that it needs a warm up to work properly. Sometimes it takes 5 minutes to give a sound, sometimes 15... Once it's hot, I switch it of, expect one or two minutes and try to switch on again, it works most of the time. It's like it needs to be warm to work as it should. I have tried to connect my speakers to B instead of A. I connected my CP player to other entries such like DVD or Tape but the problem remains. I opened the box to clean the dust and I saw that someone putted some tape around a radiator, maybe to help warming up? Do you have an idea?"

Most likely a cold solder joint somewhere in the audio circuit. Most likely on the legs of the relay that turns the speakers on or off. Also check the connections at the audio outputs. Give it a good look over for bad solder connections, given the symptoms that's 98% likely to be the problem.

Check if you're using the digital cables like optical cable to get the audio from the receiver. If yes, please select the Input mode to AUTO by pressing the mode button repeatedly. If you're using a analog cables, please try to change the sound field and check. Press the A.F.D button repeatedly to change the sound field and try. You can also try connecting a different audio source like Cable box, dvd player and check the issue.
If the issue persists, please reset the receiver. To reset the Receiver, turn OFF the unit and press n hold the MODE + button and Power button till S.F Initialize appears. If the issue still persists, you may be having 90 days warranty after the date of repair or original warranty which ever is longer. Contact sony to resolve the issue.

I'm guessing these are separate issues.
Has either one ever worked and stopped suddenly?
From the manual:
"No sound or only a very low level sound is heard from the rear speakers.
>>> Make sure the sound field function is on (press SOUND FIELD - MODE).
>>> Select a sound field containing the word "cinema" or "virtual" (see page 33-35).
>>> Adjust the speaker volume (see page 72).
>>> Make sure the rear speaker size parameter is set to either SMALL or LARGE (see page 20)."
Be advised that using any Tape Monitor loop (that's what the MD/DAT is) disables any digital sources. Not that that would explain the rear speaker failure. Analog sources can still be processed into various surround modes.
Any Tape Monitor use requires at least a live INPUT to hear anything.

Hi and welcome to FixYa!
Check the back part of the unit. It usually has a fuse that protects the unit from power overload. But since the unit is working then the problem can be on the inside. Capacitors and circuit boards should be looked at. They may need replacement to resolve the issue.
Hope this helps and thank you for using FixYa! Have a good one!
