Question about Sony KP-46WT500 46" Rear Projection HDTV-Ready Television
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 the cross 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.
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.

Why don't you just get a new "D" board, unhook the wires of the old board and hook them up to the new one. Done with no soldering
you still may have to do a little conv. on the tv, at least thats what I'm doing

You need to replace the Convergance ICs STK 392-560(2 of them) in the "D Board".
If you are not a electronic handy man, get assistance from a TV repair tech. This involves de-soldering the IC and soldering back without damaging anything else in the PCB. The ICs are mounted in a heat sink and would require some heat transfer compound to fix it back again. Without the compound, the IC may fail prematurely.
Word of caution :- You are dealing with very high voltage components inside the TV and should be careful before you attempt to repair anything inside the RPTV.
