RCA HD56W58 Troubleshooting

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?

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

I love my tv so I hope you can help. It made a high pitched sound, then just shut off and there's a burning smell. Any ideas would be welcome.

UNPLUG SET if you have not done so--fire hazard exists.

I would open rear and LOOK--see what if anything you can see that is burnt---all parts will have a location number printed under or next to them---will point to where problem is---make sure set not plugged in and do not stick your hands inside.

Same problem, high pitched noise over regular sound and no pictur

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.

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

WOW...had a high pitch noise, came and 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.

RCA Model f27650 High pitch squeal

the high pitch squeal indicates shorted component/s. the transformer goes hot co'z its being overloaded by the shorted component, it too could be the one creating the squeal!!

if you have experience with electronic troubleshooting, try to test some of the components particularly on the secondary part of the transformer.
Be careful and make sure the TV set is unplugged.
test for shorted diodes and transistors, if you're in doubt of your readings try to desoldering one leg of the diode then proceed with the testing/measuring. replace any of the bad components you find exactly with same part number or replacements with the same rating.

spend more time on it resoldering some other cold soldered components.
