Hello, I hear this constant high pitched noise, almost like ringing, but even ... pitch

sounds like fan or possibly hard drive is about to fail

Sounds like a transformer or choke that has loose windings and they are resonating, you can pull the back and put small amounts of silicone on those components or replace the power board

if the speakers are built in try a new rca cable

Sounds like a hardware problem, but it could be software.

What happens when you mute the volume?

Does it sound like its coming out of the speakers or somewhere else?

never had that problem with my GS400 but on my 95 maxima, i used to have that same high pitch squealing noise... i used some belt dressing that i got from R & S Strauss for a few dollars and sprayed it on my belts and pulleys that ran around the alternator, compressor, etc. and never heard the noise again. hope your problem is as simple and cheap to fix as mine was

need to change a new pump.

Ok maybe this may help .... there is a coil LL08 I believe... somtimes it creates a high pitch whine like you describe.. its stands up on the deflection board..it basicaly a large coil of copper wire....you can take silcon and put on the coil...in effect damping the ocillations...hope that might help

I have a very high pitched sound and when I move the tv it will stop for a second or two and then start again. The sound sometimes stops all together. But very high pitch sound.
