RCA CTC 168/169 Pincushioning Problem

[[email protected]]

Hello...

My Tv died the other night. I had a look at it and it appears to have a
bad HOT and a capacitor (Blue In color .5uf 250 volt) The Cap swelled up
a little. Replaced the 2 parts and also checked a large diode next to
the HOT to see if it was bad. Seems to test ok on the Meter....

Put new parts in tv and it fired up nicely.......
But I noticed that the bottom and the top of picture seems to be bowed
outward.
and the middle seems to be inward.

I believe it is a pincushioning problem....
I then checked all caps in deflection circuit but couldn't find anything
bad or weak.

Any Suggestions?????

I Have been out of the service business for 20 years plus and my skills
needs a little brushing up..... Any help would be nice...

Thanks In Advance

Thanks Art...... Those items that you mentioned are ok in the deflection
section.

I even doubled checked.

Thanks for the info though.....much appreciated...
If any one else would like to give it a shot to help me out, it would be
greatly appreciated........... My hair is getting thinner by the hour looking
at this problem.

Thanks

Michael:
t xr = "transistor" ....... usually abbreviated "xstr" or tranny or
.. . . . .

By the way Gary was spot on with the short of the Pin Transistor. For those who
