I need to line up my colors and magic focus does not work.


If picture looks 3d in some way you have a convergence problem.

This set should use two of the STK-392-150 CHIPS FOR THIS.

The repair can be a do it yourself one if you have some skill. Magic focus only attempts to adjust at about 18 points on the screen.

Parts cost will be under 25 dollars. The repair consists of getting at the chips (2) and replacing both--on EBAY they will cost under 15 dollars (I fix sets and use a seller there).

If I can help make a comment here and if this told you something you did not know, rate this solution as very helpful as I do this here for free.

Magic focus


you need to replace the convergence Ics thats why youre unable to align the blue. If youd like me to post a link where you can get replacement ICs as well as free tech support and instructions let me know and I will post the link.

Magic focus


That's a DP23 chassis, why replace the deflection board? Does magic focus come on the screen? Does it just no converge the picture? If so, it's likely that the convergence amps have failed.
That unit takes two STK392-110 Sanyo built Ics at board position Ic04 & Ic05. If you replace them I'd upgrade to the STK392-150's for greater reliability.
