I have a RCA HD52W57 tv. The problem is when you plug in to the comp or DVI inputs you have no sound. When you plug in to any other input the sound works just fine. Any suggestions?

Smelled smoke and hot wires, tv went off and never came back on again. opened back and found only one small part looked burned out, ( broken and a little brown on the board.) Part number R14705.


Thats a 27K 1/2 watt Carbon Composition resistor 5% tolerance. You got deflection issues so a replacement resistor will most likely fail unless you discover whaich componenet on the deflection board caused the resistor to burn. The deflection boards have been discontinued for your model which has the ATC321 chassis. But you can get a remanufactured ATC321 deflection board from www.tvrepairworld.com

From your description ..actually this is a common problem and no simpley replacing the resistor will not fix it. this chasis has a problem with what is called the high voltage splitter.. there was a number of these made with a defective splitter. RCA HAS ISSUED a service bulliteen for certain models and serial numbers. the board and the splitter is generally replaced. (I just worked on one of these 2 days ago and got and order in for the parts) ......just reread the tech bulliteen.. the spitter which develops a crack is rca part number 258512 the resistor or the part that burnt is resistor a common 27k 1/2 watt 10% carbon resistor

Sounds like the convergence board has gone bad. Usually this costs about $300 to $400 to repair, and takes about an hour.

Check first R14705 to see if burnt! If so then HV Trans is bad. Also if you need schematic try www.servicemanuals.net
