Convergence problem


If this is a kp-46wt510: You need to replace the two convergence ic's; they should be STK 392 types---look inside and you will see them on identical large metal heat sinks with fins--the ones your set uses will have the full stk number on them(stk-392-110 or stk-392-560 are the most common for Sony)

They both need to be replaced and any bad fuses or resistors around them that protect them found and replaced---Most of the time just the two chips need to be replaced and the set adjusted with the remote; I have done hundreds of these sets and usually the repair takes about an hour and can be done in your home.

If this has been helpful give me a vote here as I do this for free.

Sony KP-46WT510 convergence IC's and checking resistors



You have 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 but stationary.

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.

Convergence problem


you will need to replace the stk ic's they are mounted to 2 large heat sinks in side the tv. the ic numbers are on the chips themselves. i do believe it is stk392-510 for sony. once you have the number you can buy these anywhere online. just put new ones in and should be good to go. if this doesnt work then there are a few resistors and fuses by the ic's that sometimes fail.
