    during normal performance in surround sound a channel change was made and sound stopped abryptly. I have disconnected and started up again. All appears normal on the display screen but no sound to speakers. Disconnected optical cable and reconnected. Feedback buzz when disconnected but no sound when optical is re connected

If you're not experienced with troubleshooting and repairing electronics, I strongly suggest professional service. There are internal problems and most likely several components will need replacement.

I accidentally plugged my 110V amplifier to 220V outlet.It has no power anymore.what possible solution for this. Thank you very much. Do I need to replace the rectifier in it's circuit?

Hi and welcome to the site,

Initially, on a completely dead Sony TA-N9000ES, primary suspects to be checked would be:
  • 8A F1 fuse;
  • primary winding of T1 transformer;.
  • fusible resistors R816, R817 and R818.

Good luck and thank you for asking.

Playing it loud for about 20 minutes it suddenly fell silent. Power is fine as is fuse. What has blown?

Hi, even though the mains fuse on back of amplifier is fine, the speaker fuses might have blown.
Now really you need to take it to get repaired but if you know someone who has electronics knowledge they could look inside the amplifier to check the speaker output fuses.
I wouldn't want to advise you to do it as there are dangerouse voltages inside the amplifier.
If you need more help, I will guide you.

Regards - Anthony

HOW TO WIRE AN EQUALIZER TO A SONY TA-FE370 AMP

You can't wire an equalizer to this amp unless you only want to equalize one source, because it doesn't have a tape monitor function.

No sound

When the amplifier will turn on but not produce any sound that is usually an indication of either the high voltage power supply inside the amplifier is not working, or the amplifier IC or amplifier circuit is damaged. It is not something that can be repaired unless you have experience working on electronics.

Sony TA-N9000ES Flash light when turn on.

an amp of this size generates alot of heat internally when in use as these use mosfet ICs and can get very hot.
your problem is most definately dry solder joints and possibly quite a few at that.
i've repaired quite a few sony surround receivers with similar problems and have all been down to dry solder joints.

hope this helps.
