Convergence problem


The convergence board is bad in this set. Samsung no longer has this board in stock. You will have to take the board out and rebuild it by replacing both of the STK convergence amp IC's These IC's are soldered to the printed circuit board. They will be standing up against a metal plate, called a heat sink. They are black in color and are about 2" by 3" . They have white lettering on them that start with STK and the some numbers. You get those numbers and go to mcmelectronics.com, enter the exact number of the IC and order two of them. Before you install the new IC's you will need to apply some heat sink compound onm the back of the new IC's. This heat sink compound is avaialable thruogh radio shack. Good Luck

Bright green flash and red arching lines


You need to check the bulb in the back of the set as it could be on the way out . just check to see if the bar in the bulb has gone black as it is a good sign the bulb is on it's way out . the bulbs only last 2-3 years or 4000 hours . If thats ok you most probaly have dry joints on the tuner , they just need resoldering
