`How do I fix my LG tv? It's making a high pitched noise and there is a black screen, is it fixable?


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.

RCA 57 inch hdtv Model#HD56W58 has sound but no picture.


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.
