I recapped it and it was working fine until it lost V sweep during a burn-in process I use for TVs that I plan to give as a gift (leave it on for a long while like the new owner might). No transformers to fry, these have fuse resistors, new 1N4007s and a series string but these ALSO have some of those bug-a-boos that Sylvania was particularly famous for like tin whiskers and PC board failures.
I used a Sencore SS-158 to inject a V sweep signal which cleared the output transformer and yoke. I suspect a tin whisker, only after checking everything else. I smelled toasted carbon when I discovered the fail, but all the pertinent resistors check within tolerance.

I never thought too much of Sylvania TV's.
The 21,23" Halolite consoles with the exotic cabinets, that had that cheap & nasty chassis were a farce. They were expensive and the owners really thought they had something.
I thought, while working it, for the money you paid, you could've bought a good set!
