Getting a high pitched sound from speakers or Headphones once the system is turned on. No matter what settings on a Marantz sr 5008. Wondering what may be the cause of this.

I think its the flyback and its starting to leak. this is a component responsible for the high voltage of your tv set. always observe safety in dealing with this. Have it check by a qualified technician. Good luck!

Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages.
Good Luck!

I had the same issue. The tech that came out today removed the transformer on the power supply board, "resealed" it, and replaced it (re-soldered the same part back on) -- the transformer apparently vibrates because it was not properly sealed. BTW, mine was about the fifteenth that he has performed this repair on within the past couple of months -- all 32" and 26" Samsungs. Now, it appears to be absolutely silent.

SOURCE: Total loss of sound...what to do?

please repeat your setting first- and then disconnect all speaker out.
connect your speaker one by one until you find the bad one and change it-you can also apply contact cleaner spray over volume control and move it many times-please do not forget yo unplug headphone jack first.
