I used this forum to find a repair for my Toshiba TV and I found posts on how to repair the Hyper Board and that worked marvelously so I thought I would try fixing my friends Sony receiver. He says that the sound level for the regular RCS inputs has been "staticy" and with the digital inputs he has a chirping sound coming from the speakers. I haven't heard this but he says he can't use the receiver because that's pretty much all he gets out of it. Any quick ideas on this (besides replacing this old unit, which is what I told him)?
Make sure you have fib/opt cables are securely inserted in right ports. Switch through "input modes" on front panel; opt, anal, auto. This unit is tricky and unecessarily complicated. Read through manual carefully!

Check that the mute is not on.If a headphone is plugged into the receiver the speakers will be muted.Verify the the output selector is set to the correct source.Here is a simple check.Select a strong FM radio station.Plug in a headphone.If you are receiving an audio thru the headset.Then disconnect the headset and see if the audio is transmitted to the speakers.If you still have no speaker sound check to see if the speakers have fuses which may be blown.I would try another set of speakers to determine if it's the amplifer or the speakers.The amplifer has fuses as well.

In most cases the output is faulty as the MOSFET's shorts and so the drive board has to be changed. This is an expensive replacement and many when the estimation is done opt out. In some cases the protection is due to the fault of the protect circuit, failure of transistors or passive components. Since most of the board are hard to access , the work estimation is high as boards are replaced.
yes either buy the sony dock for mp3's or go to Radio shack and buy the adapter that goes from a headphone jack to a red/white RCA plug get the gold tipped version and just use an open interface on the back phono, tape, whatever you have open.
Here is the link for the user manual if you need it;
Check page 54 for details of the error message - it should disappear if the speakers are connected properly and the unit is switched off and on.
Check page 17 for speaker connection details, and ensure they are all correct.
Check page 19 for details of the factory reset/memory clearing. Hopefully this will clear the error code and let you set the unit up.
Hope this helps, please ask again if no luck :)
