Replacement STK numbers for convergence amps

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".

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

DIODE RCA Part Number: 198589

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

Hitachi part number JT23051 is Obsolete the new part number for the Deflection Convergence PWB is JT23051R its available from Hitachi for around 350.00

The problem you are having is with your convergence amps your set uses STK 392-120's if you replace them you will get your convergence adjustment back, Philips part number is 932212344682

Sounds like the classisc case of convergence amp ICs needing to be replaced. What is the model number of your set and I will post the STK numbers you need as well as a place to get replacements with free instalation instructions

you need to replace your convergence ICs. Post your model number of your set, and I will post the correct stk numbers and a link where you can get new ones.

There are a number of different STK type parts. You need to look on the old ones for the part numbers. May have to dissassemble the heatsink to see the number. STK is pretty good about its numbers and you should have no trouble finding them.
