Blue converence was intermitten now out on sides


If the IC's say have STK printed on them, then they are the convergence IC' s. should be three of them, replace all 3 , and the burned green coils, sometimes these burn as they supply the volts to the STK's. good luck, be safe..

Converence


green is fixed so you have to move red and blue to green.
by using the remote you may find a simple converge function and open this and using arrow keys move the blue or red first to center of screen, repeat for other color you should see the lines moving toward a a white center point.

if the lines do not move with remote try manual ...menu on the set. if still no movement you have a problem on the convergence board and need a tech to fix.

A service manual will explain complex convergence to the detail .
but this might take hours to get it right.

Blue moon works intermittently


Take the hose handle apart and look at the bottom side of the switch circuit board. Sometimes a contact or 2 break loose from the solder and will work intermittenly. Resolder the contacts if this is the case, put back together and try again.
