Good question, but I know of none. We do a lot of these older Mitsubishi
sets and rarely see repeat failures unless related parts are bad.
Check/change all of the caps in the supply and pump up circuit paths related
to the vertical output. They are usually going to be bad. Also, you might
check the yoke. If you pull it off and look at the windings you may find
some corrosion (green or black) which might indicate an intermittent short.
We have seen a couple of these.
