I have a Pioneer 53 in. rear projection TV which will cut on with green light show image of channel and image will be covered all in red the shutoff by the protection circuit with red light staying on. I have pulled the red wire out of the splitter for the red lamp and cut on TV and TV works fine except no red color. I have also put the blue lamp (red wire) in where the red lamp was and everything works fine except no red in picture.
Have isolated it to the red lamp and its components, wondering what next to test or replace?

Did you have double image before changing the stk's ? If not then there was no need to change them.. Pioneers are known for bad solder connections especially in the power supply section.. suggest checking that when you changed the stk's that there are no solder bridges between the pins of either stk ICs
sounds like the high voltage transformer arc or one of the picture tubes arc causing the convergance ic to go bad you can try to replace the IC heres a site to help: http://home.earthlink.net/~oleg.filippov/ConvergenceFix.htm
