Your red CRT socket may be loose or have cracked solder if not, try turning down the red gun screen control inside the set just a little. Youre experienceing what is known as retrace lines

    The crt sockts are accessable after removing he speaker panel beneath the screen. You then have to remove n access panel. Your screen contrls should be there as well 6 buttons on a block 3 are screen G2 and # are focus for the 3 CRTs

Colors arched and overlapping


if the option for convergence is still listed under the setting section of the on screen menu, then you need a convergence power supply board. If the convergence option is missing from the menu you need the ITC222 convergence missing repair kit. You can get either one at the following link they include instructions for the repair.

Red arching lines


is this that you are adjusting called convergence? If so then if it's really bad you can try to reset convergence, if not then the red needs to be aligned up with green first then blue on green. Can you provide a picture of what it looks like?

It sounds like you are going to need to have the convergence IC's replaced. Not really a hard job, but the job requires the proper tools, soldering skills, and a service manual to get the proper part numbers and to perform convergence alighnment in the service menu after the IC's are replaced. Good Luck
