I have a K4900 which has a very distorted picture. The vertical is squished too small and the horizontal is expanded too far. I cannot get either to adjust. I have just re-capped it with no luck. Any suggestions?

you can tell its a 4900 by the solder points for the flyback...why the frame say's electohome i have no idea...

Someone swapped it out. My question now is: What all did they swap out? If this was pieced together I think my original theory of a mis-matched chassis/yoke is looking good...
If the yoke connectors are red/white/grey/brown, then yes. if they are red/blue/yellow/green, then no.
and the -055 on the board shows that it is a later series chassis.
a mismatched yoke would show foldover - one side fine and the other side squished. It wouldn't show both sides squished.
4900's are notorious for lots of bad solder in the vertical section (basically all "400" parts). You may also need to replace your vert transistors...
Well the yoke connectors are blue/red/yellow/white.
I'll start with soldering the vertical section and see where that gets me.
Isn't this dangerous as others have said? What do I need to be careful of? How harmful are the x-rays that could be emmitted?

You can "safely" replace the suction cup without changing the flyback.
