Hello there,
Being a practical technician I would assist you technicaly.
Please find G-Board in your TV and replace IC1502 & IC1506 (STK392-150)
Before replacement of above said ICs, check follwoing Fuses (PS1501-1502-1503-1504-1505 & 1506) all are 2A rating. If you have VOM (Volt Meter) then confirm +15Volt & -15Volt supply on G board. If you need further help, I can provide with pictures of related circuit portion.

Sony KP-46WT510 Rear Video Projector Convergence Problem


Subject

Video bowed in, convergence out, PS5001

Symptoms / Customer Description
Video bowed in and convergence is out.
[Primary Symptom Code: 1436 ]

Solution

Found PS5001 on G board was open.

HQ Comments: Could be cold solder joint on one of the STK IC's on the D Board. They run hot and the solder connection might have broken down causing intermittent condition which could have opened the fuse on the
-22v line.

You can find the full repair manual Here!

If its the color won't align its the convergence board. First you could look for bad resistors and or capacitors
