the jungel ic. It also may contribrute to your symptom.

Hi,
I replaced all electrolytic capacitors Cxxx I could find. I don't have a
schematic, but I guess C3xx are capacitors in the vertical deflection
circuitry.
I also changed IC301, R287 and a couple diodes.
The result is still the same. It started by the top of the picture
starting
to elongate, and then the picture progresively diminushing in size over a
few weeks. It is now about half the size of a normal picture, in the
middle
of the screen, with retrace lines visible when no RF signal is present.
What else should I try before I trash the TV?
Suggestions anyone?
Thaks in advance.

Hi...
Don't trash it for that; specially not since you've
already invested in it.
Betcha a donut that there's one cap left you haven't
yet found. Not necessarily near the ones you did find.
Probably larger, higher voltage. Keep looking.
I like chocolate covered
Take care.
