RCA F36650 36" 2002 xbox ready tv

When I plug in my tv there is a loud squealing noise and the tv won't turn on. I read on the web that it is a component that is shorted out. Anyone have an idea as to what that component might be and is it something I can replace? I'm pretty handy.

Yes it is the Horizontal Output and a few capacitors and resistor that needs changing. If you are good at desoldering and soldering you could do this. I think on this set its the Q4401, caps C4402, Cr 4402, Check Q4802, C4102, If you just want to try new parts and hope it works then you have to check voltages at different points to fix set. Now it also could be Bad Flyback in this set too. I have seen where you change flyback and horizontal output and c4402 would do it. R4118, R4114

RCA Entertainment Series 32" Plus Gold, GEMSTAR, xbox ready has been in the shop twice so far. Transformer replaced and 6 months later the picture suddenly had horizontal white lines that gradually spaced apart more from top to bottom and it had a gray hue and fuzzy, but I still watched it for 3 months that way. Today I turned it on and about a minute later I heard a loud crackling sound coming from the back and the picture disappeared, screen went black. Is it worth fixing again? Please contact me at

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.

Rca f36645

A squealing noise generally indicates that there is something loading down the switching power supply. Generally a shorted component will do that. Without any other information it's hard to tell which circuit could be the culprit. It may even be a faulty power supply itself. Was there any problem prior to this condition? Any odd picture problems, shrinking etc. or sound issues, tuning issues?

The squeal maybe produced by the flyback, It looks like is a common defect on this chassis, but check any other defective part in the horizontal section and the power supply as well.
The fly back part # is 257805 but i would call RCA just to verify it or you can check inside the Tv's lid for that part number.
Check website.
Good Luck.
