Get it to a tv dealer but my guess is its died. It may not be economical to repair but you may be pleasantly surprised and its a small job. LG are usually pretty good so I'm surprised its gone at this age.
The tv have a colors wheel,have a whinning high pitch sound,mean colors wheel is warping not spinning right any more.The colors wheel is dead,must be replaced.The tv have high pitch sound,shutdown the projection lamp.The projection lamp might be dead or not?Not yet determine dead or just shutdown by the nonfunction of the colors wheel.
sounds like the projection bulb went bad. change the bulb and it should work. sometimes they make a high pitch noise when they are trying to turn on. the bulbs seem to last about 2 years for me.
Ur high voltage is dead,the FBT.The flyback transformer is dead.The big black block of plastic with a wire with cap hook up to ur CRT(tv tube).Might
also ur DM power board,have burns capacitors,check for puff ups capacitors must also be replace as rebuild board.U know how to solder right?Tries thes websites for parts.Tv Repair World.com Shopjimmy.com Partstore.com or Ebay.com.
Hi,
Symptom shows high pitch sound is of color wheel that is not spinning any more so TV stay in protection mode and does not power up.
TV requires color wheel replacement.
sounds like the flyback which is a 259296 flyback. You can get the replacement flyback at the following link with free instructions http://servicemanuals.vstore.ca/
WOW...had a high pitch noise, came and went...got worse as time wore on. Would shut off the set, times it cleared times it didn't. Warranty folks set out a TV repairman--said he had worked for RCA exclusively for years...anyway, explained that the 1k hertz noise was a known issue with the HD56W58 and that RCA’s published fix was "nail polish" applied on some board, had something to due with power and vibration...long story "presto" noise gone...but after 6 or so months we began to hear it again—say it ain’t so, but yes the high pitch was back. Same repairman, this time bigger problem...along with noise, the network card is broke and Fry’s Electronics (Irving, TX—hear that Corporate HQ at San Jose…your Irving store needs to be leased in and tote the company line...where's the customer satisfaction???) is balking at a “equal” replacement, they see it as take the less than equal product or get store credit…good luck & wish me luck with the equal replacement they tout when pushing the warranty.
