It's likely a capacitor associated with the power supply having gone bad. It's obviously beyond your expertise to repair it yourself. Find a trustworthy repair shop and take it there.
THAT TV HAS WHAT IS CALLED A COLOR WHEEL WHICH SPINS AT VERY HIGH RPMS AND CAN MAKE HIGH PITCHED WHINING/GRINDING NOISES IF A FAN WAS BAD THE TV WOULD SHUTDOWN AND THE SOUND WOULD BE MORE DULL SOUNDING.
This tv is under five years old?Yes,it is worth fixing.Over five,i would compare the prices for a new LCD tv and the quote priced from the Tv Tech.for the old tv.This tv have high voltage problems around the Deflection circuitries area.Could be any things burn in this area.The high pitched whine sound,i'm sure it is from the FBT-the high voltages flyback transformer,high voltages current have no where to go.Must hire a tv tech. to troubleshoots and replace parts on the Deflection circuitries area.Also the FBT could be dead too,because HV Current bounces back forth and have no where else to go.The prices to troubleshoot unknown problems is about $400 bucks and plus cost of replacement of parts.
The colors wheel is dead.That why,u hearing high pitched whining sound.The colors wheel is spinning off of is motor axis and grinding it sides walls,that where the high pitched whining sound came from.Hire a tv Tech. for the colors wheel changing,because it requiring to take out alots of the machanicals parts itself,before u can come to the colors wheel itself to change it.
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
Hi,
If after trying the TV again later and problem persist, repairs are in order.
A high pitched whine is an indication of a fault at the horizontal section of your TV. The horizontal provides the high voltage for the picture tube.
Your best bet maybe to seek the services of a qualified professional TV repairman since this involves component level repair, soldering/desoldering, use of soldering iron and VOM (testers) and knowledge of circuitry.
Good luck and kind regards.
