RCA Victor 730TV1 Horizontal Problem

[nasadowsk]

Don't discount capacitors, even Mica types. I recently had an interesting issue with my Bendix, where the picture would shrink and lose focus. This was traced (with freeze spray) to a bad capacitor in the horizontal section.

The technique is simple: Run the set (with access to the chassis underside) until the problem occurs, and then spray a general section of the set until you 'fix' it. Then narrow down your searching area until you find the one component that's heat sensitive. That's the bad one.

Takes time, but it works.
