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

My rca hdtv has triple vision. we are seeing red blue and green shadows as well as the picture appears to be curved.


you have lost a voltage going to the convergence circuit
if you look under the power supply deflection board
on the flyback transformer look at pins 11 and 12 they will need to be resoldered
and the is a fuse the will need to be replaced on that board also if you follow up i can give you the fuse location and part no for it

Green picture on screen with no other images...


Nothing that I know can corrected the problem.
if you wish, you can start by checking see if you get parts for the TV. I mean all of it. once you located the source, then I would start replace the main source of problem.
I would see the total replacements are more than the new TV cost.
it is your call.
I would just go buy a new one.

Don't understand


Can you look on the rear of your set and give me the chassis number and I can explain as that model used three different chassis designs one was ITC222, then ATC221 and ATC321 it should be marked on the rear tag.
