Did you check for open resistors coming out of the ICs. These commonly go open when the ICs go out. The are located right next to the ICs there are numerous resitors all with no color bands very easy to locate. Check these resistors.

Red Covergance Issue


Solution: 

Your TV has a convergence problem. Here are some of the most common symptoms.

Screen looks 3D
One or more colors can't be adjusted when using the convergence menu. 
Screen is bowed in or warped.


Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence or magic focus section.

Try to adjust the convergence.

You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

Its a fairly easy fix. 

You can get a repair kit that includes all the parts from www.TvRepairKits.com. The kit includes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc. 

Everything you need to fix it yourself.

Sony rear projection convergence


This is a convergence problem that is either bad connections on the convergence ICs or defective ICs. IF you can solder and feel comfortable working inside the set, you can fiox this yourself. Let me know if you wish to attempt the repair and I'll post more details and instructions.
