Question about Televison & Video
It certainly sounds like a convergance board issue - very common in older RPTVs.
The convergence of the three color guns is controlled by a pair (sometimes three) convergence ICs (integrated circuits). You can't miss these if you look inside your TV. They are huge and mounted to big heat sinks.
What normally happens is they fail due to heat, sometimes at the joints, and take a few other components with it.
To have this repaired by a pro will likely run you $250-$400.
You can do it yourself for about $50 in parts and a couple of hours of labor. I should be able to provide the part numbers and you can go for it if you feel adventurous and have access to some basic tools and a soldering iron.
Let me know,so that we could proceed.
Hope i helped you.
Thanks for using ' Fixya ' and have a nice day!!

Hi: there are some small micro fuses on the deflecton board that has opened replace these fuses should return the set to normal, you man need to only replace one. Also these fuses open because of bad connections around the flyback transformer so after replacing the fuses resolder the area around the transformer and any related componetes in this area.. The board you need to check is the Deflection power board it's the board on the left of the set looking from the back. the fuses are at the back of the board nearest you they may be green or yellow in color...do a continuity check on each on to determine which one is open. meter should give a contionus beep when one is good not when its not.
