suspect it's 1 or a couple of bad capacitors in the vertical deflection circuit the caps are in the 400 series, c400,c401,c402, etc... check or replace c414,c418 & c417

SOURCE: convergence board
It wouldn't be the entire convergence board, you more than likely have a bad convergence STK-IC. Replacing the IC will take a good bit of knowledge and training as far as electronic repair is concerned, plus a complete convergence set up. In other words, unless your certified, you need to contact a tech. The convergence set up alone has driven men to drink.....

You likely have an elevtrlytic capacitor bad on the B+ line to the vertical ouput ic. If you continue to use the set like this it is likely the vertical ouput ic will fail.

The vertical output IC has stopped working. The vertical output IC is the part that drives the coils in the yoke that spreads the picture up and down. This could be because it has cracked loose from the board (solder joints) or it simply burned out. Sometimes a bad pump-up cap will cause the vertical output IC to short out, and when the IC shorts out it often opens up a small value resistor next to the flyback. This is a relatively easy thing to repair. A qualified tech will be able to tell exactly why the vertical output has stopped working and repair it for you.
