I have a JVC rear projection that has red wavey line on the top and bottom of the screen but the mittle looks ok. Any ideals? Thanks Robert
You need to replace the convergence IC's. That is the most common issue with any CRT type projection TV.

If you take off the front lower grill (4 screws 2 on each side and 2 more small screws behind the input door on front) then remove the panel which if I remember has 4 to 6 screws holding it. You will then see the convergence board with 2 STK392-110's or some variation of them on the convergence amplifier panel. You will have to check the associated resistors around the IC's as most likely some might be bad. If you replace one IC's you need to repalce both of them.

Sounds like convergence issue--replace Stk IC's mounted
on large heat sinks. Check power supply for open fuse device.
Re-check convergence alignment.
