My Sony KP-43HT20 projection TV was very good. I accidentally pushed Flash Focus button and it lose the convergence. I pushed Flash Focus button again many times. It could almost convergent the red and green colors, but couldn’t move the blue color as shown in the figures. The blue tube couldn’t project the parallel lines and the pictures are blurred, Could someone advise me how to fix the convergence problem? Thanks.
Replace STK-392-110s or 150s upgrade with 180s replace both ics.
replace both ics this way they are equal ,if you only replaced one you will have more problems so replace both with same STKs.392-560s

I really couldn't find the 3.15 amp slow blow pico fuse for STK392-560. Would you please help?
Thank you very much.

Ladywinn:
Sorry that I haven’t got the time to replace the STKs. I found that the pico fuse PS8006 (3.15 amp slow blow pico fuse) is open and 5 resistors (4.7 ohm, 1%, .5 w) for blue vertical are slightly dark. I assume I also need them to be replaced with STK together. However, I don't know where to get them. Place advice.
Thank you so much.

Ladywinn:
