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.
Stephan

Replace all the capacitors with the same first number as the vertical
output
ic. i.e. vertical output ic IC301, replace C301,C305,C308 and maybe a
couple more.

I have aToshiba CF2665K that is experiencing vertical sweep problem
(about
half the vertical picture with retrace lines).
This has been worsening slowly, and I'm pretty sure it's a defective
capacitor somewhere in the vertical circuitry.
The problem is I cannot find the schematic anymore.
Would anybody have a schematic for this TV, so I can locate the
capacitors
?
Thanks
