Somethings with the picture

Our rear projection Magnavox was working fine and all of the sudden it has a semi-circle that looks like a rainbow at the top and bottom of the screen. What could cause this?

Its the convergence problem.and the internal board needs to be checked with a meter to replace the faulty component.it also cayse if the capacitors or ic on the board gets loose and can be solved by dry soldering on whole board.just check out and make it proper.

Picture with rainbow colors


The convergence circuit is not working. There are bad solder connections on the flyback transformer and a small fuse has opened up. This is not easily done yourself unless you have a technical background but an RCA technician can fix this no problem.

Start bt realigning the convergence by using the auto focus switch. If this doen;t work, you may have a bad convergence chip. Good Luck
