Hi, It seems color wheel problem in your tv that gets problem after some time and you hear high pitch noise along with picture flicker. Color wheel need to be replaced to solve this issue. Required color wheel is available with PartStore.com (click to view image of part and price info) and it is job of qualified tv repairman because light engine will take apart for that. Hope these info will help you. Thanks.
This is an unusual failure of a non obvious part in the power supply putting noise into the circuitry of the TV.
you either need a competant tech to work on it or if you are good at connecting up cabling just swap out all the guts.

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).
When the TV is flickering, do you notice any noise in the audio? If so, it could be a loose connection inside the set or a High voltage transformer going bad. Does it constantly flicker or come and go. If the latter, can you slap the side of the TV or jar it to get the problem to come and go? If so, it is likely a bad connection inside the set. I'm assuming that when you were playing the movie that you used the A/V input jacks rather than using the tuner on channel 3. Otherwise the tuner could have bad connections or bad grounds inside. A repair shop will most likely have to fix this problem. If the set was over 9 years old however, I'd upgrade to a new HDTV set.
