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.

Sony kp 46wt500 has 3d screen what might the problem be?


If convergence out ICs got defective then TV shows that kind of picture.
Replace IC8001 and IC8002 on D Board, both big black ICs are mounted on aluminum heat sink and number STK392-560 would be written on it.
Required ICs are available in Part Store, click that link to see an image of IC and price info.
If you are not comfortable with soldering parts in circuit board, call local tv tech to replace it.
Thanks.

Replace ICs on Sony CRT


Since the IC's need to be unsoldered from the board you should have a professional servicer do it for you,there is always a chance of lifting a solder trace.If that occurs then you will have major problems.

If the D board didnt correct the convergence issue the problem has got to be the wave generator on the A board or possibly the Velocity boards themselves that are bad.
