Did you replace the pico fuses on the G board there are two and usually one will blow when the old ICs fail and just replaceing the two ICs on the D board will usually not fix the issue untill the two pico fuses are checked and the blown one is replaced.

Convergance color off set on screen


very common problem the 2 convergence ICs and the pico fuses will need to be changed. The Sony type 1 convergence repair kit from www.tvrepairworld.com is the correct kit for your model and contains the two ICs and the 8 pico fuses plus the CD with repair instructions.

Kd-46wt500 sony big screen colors dont line up is projectors goin out picture on tv is blurry pic looks stretched out as well


Can you verify the model number and see if its A KP46WT500 model? If so chances are just the convergence Ics ( stk 392-560 ) and pico fuses are the problem. There are 6 3.5 amp pico fuses directly beneath the heat sink fins on the D board ( where the Convergence ICs are located) Check those six pico fuses and also two 5 amp picos on the G board ( where power cord plugs in) if any of the picos on either board are open then the Convergence ICs will require replacement.

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.
