I have this Rca Tv I bought about a year ago...I read on this site that the common problem of this model tv not coming on is related to the transformer part# 271996. Is that true? And if so is it something a novice can replace without electrocuting himself?
When the HVT goes out, it will take the HORZ output, in short, you will hear a high pitch noise for a sec, when pluged in. As to your question, Its not a hard repair, however its not what I would call a begainer repair. This is what make the high voltage (about 32,000 volts) for you set to work. If you DO try it, becareful. And don't forget to change Horz output p# 274762. After changing the parts, unit will not run for more then 10 seconds. You have to use a volt meter and set the G2 for 290v, with no signal and blue screen. + or - 5 volts will cause unit to shut off.

Unfortunately, the Power Supply has spat the dummy out. It is giving enough power to light the LED but not enough to run the set. To replace it will probably cost more than buying a new set. But ask around your local repairers for a price before you make any decisions...
The TV was making the clicking noise and not turning on because an internal error was being detected.
Now things had got worse , and something had blown inside the TV.
The burning smell and high pitched noise is coming either from Flyback transformer or PSU board. Repair is a delicate matter and must be done by a technician.
