In some cases this is due to the fact the internal degausser stayed on too long and magnetized the CRT causing the rainbow effect. The only way you will know if the set can be repaired without replacing the picture tube itself is to have a technician use an external degausser to see if they can remove the magnetism on the tube and return the set back to normal. If that works then the internal degassing circuit will have to be repaired otherwise it will happen again when you turn it on the next time. If it doesn't work then the tube was damaged by the internal degausser and at that point you will spend over 300 dollars just in parts to repair it.

This is either a purity fault which is caused by magnetism affecting the screen. You would need to call a service engineer to remedy this as a special tool is required called a de-gauss coil. However there is also the posssibility that it could also be a fault with the shadowmask which is caused by the CRT itself, if this is the case then the CRT will need replaced & this would probably not be economical.

My sony tv falldown from the table color problem (rainbow pattern) developed but picture is ok. how to solve the problem?


It knocked the inside color wheel or tubes out of alignment. Check menus for "convergence" and try to readjust. You may need to call in a pro to fix it, but search your model number on trhe net and see if you can find the service manual.

The shadow mask in the picture tube has shifted from being dropped. The only way to fix the set is to replace the picture tube, which would cost more than buying a new set.
