I had two Sony projection TV model KP-51WS510 had convergence problem.
I was replaced both IC STK 392-560 order from MCM but still had same problem.
The convergence manually not adjustable wonder is digital convergence board bad.
Is anyone experienced same simptom of this problem before.
Please let me know had any way to fix this problem.
I did check all the resistor and fuse on D-board all test ok.
The DC voltage was all normal only -22V/DC a little lower as -19V/DC.
This problem on this Sony model met many time but never got chance fix it.
If you had some more info can help solve this problem please let me know.
I still wait for find out why cause it.
I wonder Sony had a service bulletin post out some where.
