My vertical deflection has collapsed to a 1" line. If you smack it, it will return to normal for brief period of time--i.e. looks like a cold solder joint somewhere. I retouched the toshiba NTSC chip on board but don't really know where all the other vertical components are--if someone could help me narrow down where to head with the trusty soldering iron, I would greatly appreciate it.

TIA!

Look for capacitor C4511. It's a axial cap (1 wire out of each end).
One of the larger parts on the main board. Resoldering the connections
should fix the set. If not, look on top of the board for glue. Any
parts gooped with glue will develop bad connections over time, the glue
needs to be removed.
