    My Sony Wide Screen Projection TV (KP-46WT500) has a problem with the colors. The 3 basic colors overlap--and are blurry. We tried using the FLASH Focus several times --but it didn't help. Need Ideas!

How to go in service mode for tv sony kp-46wt500.i did change the stk ic,the convergence is good in the midle but bad on the side


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.

Sony projection tv convergence issue


You will need two STK392-560 Convergence ICs and you will also need two of the 3.5 amp pico fuses as Sonys will always blow at least two of the Pico fuses. You can get replacement ICs and Pico fuses at the fiollowing link and they provide free instalation instructions. Heres the link.
