Default Re: S2055N horizontal deflection transistor keeps failing on CRT TV with the F19 chas

Small update..the caps have arrived and even though they look out of place and a bit overkill, they've worked perfectly.

I decided to add a bit of electrical tape on the top just as a safety measure.

The TV works finally. I had to replace that old tuning cap, the horizontal transistor, and the vertical deflection IC. Also i replaced a 1uF capacitor in that area that had its platic shroud wrinkled and shrunken.


But not everything is perfect still..the image is still not quite there as you can see here.

Googling this fault it seems to be address as "pincushion horizontal fault", and my bet would be some eletrolytic capacitor in the horizontal deflection circuitry.

Any guesses?

Again, the schematic if it helps:

I'm almost there, i can't give up now
