You may be on the right fault point I thinks. If microswitches fitted inside the front panel of your tv has contact problems, that is, it does not release properly, this fault may occur. You just resolder one amoung it, an go for the same type. Change all is good. It is very cheap too.OK.
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.
Tvs are wired differently these days. Your old Zenith for example probably had a selector switch that allowed you to change from internal or external speakers, bandpassing the audio from the internal amplifier to the audio out connectors. Your Sharp on the other hand may be controlled by customer menu to perform the same function as the external switch. Go into the menu and sub-menu of the audio and see if it gives you any choices for selecting internal or external speakers... If it doesn't it probably will not bandpass the already amplified signal, which means if you want to listen to your Tv on those external speakers you'll first have to pass the audio sample through an amplifier.
Hope this helps.
This is a very common problem with RCA tV sets. But unfortanatly, RCA is no longer made in this country or even owned by RCA anymore. They are a Canadian company called Thompson Corp and could not give two hoots about any problems with TV sets sold here in america. I say this from experience and try to contact them and file a complaint. ther customer service is rude and basicly calls us idiots! Alot of class action suits are pending or have been dropped as for the amount of sets they company have sold,They have attorneys working for them and delaying the cases. It is really the fault of the US Judges that are total morons about these things and try to go by un written laws. They dont have a clue as most of the US goverment does not. Your problem is not a power supply problem, But a high voltage transformer and a horizontal output transistor, and the reason why the estimate was so high, is because the tranformer is no longer available. Thats why the estimate is so high. Because who in there right mind would spend so much on a set as this. You can buy a 32" RCA(BUT I WOULD NOT BUY TRASH)At Wally World for less the $250.00 bucks! I no longer accept RCA TVs in for repair as replacement parts are so much money and im not proud to say I work on RCA TV sets. Total garbage sets!!
