Default Hitachi 31dx21b 36" TV

Set powers up, has audio, no picture. flipping through channels friend
says he sees horizontal line periodically. He bought the set in 1993
and in 97 or 98 the power bounced a few times. I'm assuming the
vertical deflection since the set appears to be functioning otherwise
from what he describes. Any safety resistors in the vertical section?
I tried to download the 5 part service manual, but only got part 1. The
other 4 (rar'd pdf) files came up corrupt when i tried to unpack em.
Any help be appreciated. Thanks. Bill

Repair the vertical deflection circuitry. ESR the caps, check the supplied
voltags, etc.
