You will need a signal generator. And need a convergence map to trouble shoot alignment. But before you attemp this, you probably have some bad solders on the potetionometers that tweak alignment. Or you will need to replace the correction ICs. I suggest you take your tv to a tech.........As you may want to do this yourself....this is a big mistake. Get help....profesional help!

Sounds like a convergence failure, it was initially probably just loose connections but now it needs new parts, here is a tutorial I made:

if this is projection tv that clicking sound it could be the ballast tryin to turn on a burned out lamp or the ballast could not be sending the right amount of voltage for ignition, you can check the ballast if its liking oil or if you see something burned in the board.

The Convergence IC's need to be replaced. They are located on the Board to the right, mounted on a large heat sink. They should be replaced with STK392-150's. The original IC's are probably STK392-110's.
The Stk392-150 is a updated replacement. Be sure to use Heat Sink Compound between the IC's and heatsink because these IC's do draw alot of current and heat up alot. Also look for any heat stressed Resisters.
I hope this helps,

Sony rear projection screen is red then tv shuts off


Can be 1 of 2 things. 1st the red tube just needs the voltage to it turned down. In the front of TV (you have to remove the lower front half of TV to access it) is a plastic square with 6 knobs. The from left to right top knobs control focus for blue,green red. The bottom knobs control voltage to each tube in same order (so lower right knob for red) turn SLOWLY to left to reduce voltage until excessive red and lines go away. If you over turn left or right set will turn off. If that does not fix it or if lines reappear then option 2 is that red picture tube is failing outright and needs replacement.
