RCA Scenium HD52W140 smoked

Hi, My RCA rear projection tv literally smoked. My dad is is an electronic engineer so we took out the high voltage board and there is a resister that is black and burnt on the board. He said he is certain that is not the only problem, but we can't find a schematic for this tv. Any idea where to find the repair manual or schematic? Or would u know off hand what specific parts to look to replace before we put the board back into the set? The model # on the set is: C357C8011T. Actually a previous service guy added the "T" to the end of the model number, so not sure if that is part of it or not. Believe it or not, this is the 2nd tiem this set smoked and almost caught fire. Not a good product at all. But the first time it was under warranty. Thanks, Aaron

Re: RCA Scenium HD52W140 smoked

More than likelly, you have a bad HV splitter, or a bad tube. What happens is that if the high voltage is shorted to ground the flyback will backfire and burn the abl resistor. My sugestion is to replace the resistor and disconect the flyback hv lead from HV splitter, if it does not smoke again then ck the splitter to graund, with your ohm metter, is no supposed to read any value.

I cannot think of anything easy that would cause the symtoms you are describing. Your power supply is working and the deflection bd is good because you have HV. The problem is signal related and all of this circuitry is on the SSB or small signal bd. The difficult thing is when replacing this bd. you must have RCA's chipper check to download all of the ssb eeprom settings so they can be uploaded to the new ssb. I'm affraid you will need a qualifier RCA service tech for this problem.

No picture or sound - TV makes chirping noise

The chirping sound is the power supply coming up then breaking down because there is a short somwhere in the high voltage. The most common fail in this area is the horizontal output is shorted ( 237470 ) but what cause this short could be simple cold solder joints or the High voltage transformer ( 239111 ) If you have noway to "ring" the flyback change both parts

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
