Sounds like you may have broke at least one of the lamps . The high pitch sound you are hearing is the high voltage that goes to it .

see if you can get a main total assy. or main board . i think the micro went haywire

call an assistance to your technician...

Tone,

Your television is overheating. If it is in an entertainment center, make sure there is breathing room. As a test, run a fan behind it and leav the fan on while you watch, see if you get more than 2 hours.

Letting it sit allows it to cool down.

Your power supply, I mean the internal power suppy could be faulty, if you know how to deal with it, check it for abnormal oscillation, or get some help from someone who knows how to repair it.

sounds like flyback problem

maybe ur screen was put into a lot of magnetic interference. so check for any magnetic rays emitting devices like speaker adapters etc. a simple check would be to degauss( its in the screen properties). raja

That high pitched noise you're hearing is the power supply telling you that it has too much of a load on it and lowered its operating frequency which in effect cuts its output way down! Normally you don't hear any thing since the power supply operates at a frequency that's beyond human hearing. In an RCA this indicates more than likely that your horizontal output transistor is shorted and this short was caused by the flyback transformer shorting. This is a common happening with RCA's You'd need to take to a tv shop and have it checked out. Stargazer

Could you specify if noise is coming from : - The freezer - The outside back of the refrigerator - The bottom of the refrigerator
