We bought this television in November of 2004 and although we can hear the sound with a high pitched squeeking, there is no picture. Any idea what could have happened and how much we might be looking at in repairs?
Yes, i had the same issue. High voltage trans. and the HV distributor (splitter) goes bad on there tv, they are known for that. I have the part numbers for the HVT p/n 258655 and HV distributor(splitter) p/n 258512. The two p/n are for HD56W58 proj. tv.

Re: RCA HD56W58 Troubleshooting
Its really hard to say as this problem could be a simple dryed up capacitor , all the way to a HI Voltage transformer?? Im glad your not going to attempt this repair by yourselfs , as theres several HI VOLTAGE issues you need to know and deal with when servicing todays tvs. ITs not like it was 30 years ago , where you could take out the tubes and go to the drug store and check the tubes. In those days everyone who wanted a quick buck used to say they were tv repair persons. NO way now-a -days as all tvs and electronics are all solid state electronics and theres NO user serviceable parts inside these sets. its best if you have no training to talk to friends and peeps to whos the most honest and reliable repair place. Good Luck

No guarantees with this diagnosis. But it sounds like an HT ( high tension) leak This is often caused by the lead becoming partly unplugged ( being bumped or moved) and because of dust buildup it arcs making a high pitched hissing whistle.Ther lamp may also have been affected by the HT leak. The safest option for you is to call a service technician to it, as opening it up could cosntitute a a danger to the unskilled.
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.
