    I can't fine the D board either, or the STK392-560, or the heatsink - what is a heatsink (what does it look like).

    My Sony KP-46WT510 all of the sudden has a picture problem. It has a ghost image on the picture and all menus,(Cable Box, Cable Info and TV Internal menu display in a concave pattern. The manual focus does has a series of plus signs in the same pattern and only appear to line up down the middle and misalign worse and worse as you go out to each side.

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.
