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.

Here is a quick test....

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

Try to adjust the red and then the blue 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.

Solution :


You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.

I hope this will solve your issue.

Good Luck.

If my solution proves useful please accept it.

Arjun

I think that if you go to the menu and under setup there will be a convergence option, or at least with my sony 48" thats what it is.

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.
