IN THAT CASE YOU NEED TO REPLACE THE CONVERGENCE STK'S AND SOME TV'S NEED A INTERNAL ADJUSMENT AFTER REPLACE THE CONVERGENCE.

Convergance chip


devices: Any Projection TV with a Convergence Amp board

If I knew which Mitsubishi Projection TV you're looking at, I could help quite a bit more. In general, the "convergence chips" on a typical Convergence Amplifier board are actually two STK's mounted to large heat sinks. "STK" is electrical engineering slang for "Convergence Amplifier Integrated Circuit".

Here's a helpful Solution archived at FixYa:

You'll see in the photo that the STK on the PC board actually have part numbers on them that begin with "STK".

Hi:
Your problem is the convergence circuit, you need to replace the convergence Ic's there are two large black IC's mounted on a large metal heatsink. The part numbers are STK-392-110 replace them with the same part number or use STK-392-120 for better and long lasting.

Hi, the "trick" to this is you don`t need the samsung part number because the stk 392-040 is actually made by Sanyo, call this number and you`ll get exactly what you need 1-800-575-9833 there in Orlando, Fl. and only sell original Sanyo stk``s which is what came in your tv, make sure you check for burnt resistors around those stk`s before installing and powering up your set with the new stk`s, video-tek

RCA CONVERGENT PROBLOM


The convergence problem is likely to be in the convergence power supply which is located above and between the two boards which lie flat inside the chassis. The power supply has a chip on it which is a common problem (If it is not the transistor type then change the whole board.) part number on the chip where the metal heat sink is located. Part number may be STK 730-010 or STK 730-130 both number will work and must be unsoldered and new soldered in.

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
