Thats the regulator chip for the convergence circuits thats the one youre most likely needing, as your chassis doesnt have convergence ICs. You can get that IC at the following link and they will provide free installation instructions and free on line tech support just in case you need assistance. Here is the link.

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".

Mitsubishi 55" Convergence chip location? Where


Look for a big heat sink (big piece of aluminum) right behind the back access panel. The brown pressboard that you need to take of to have access to the inside of the chassis. I think there is two STK chips for this tv. Older mits only had one. The STK chip is black, should be about 3" long with about 20 pins on it. It may have a metal clip covering the part number on the front.

Convergence Board (I hope)


check this out I have the same problem check your solder spot make sure the solder points are not touching one another, that could be one of the reason is doing this or just to make sure you can desolder the stk chips clean the holes where the pins go trough the board and power the tv with board and if the tv start fine if could be bad stk chips be very careful when desoldering or soldering good luck about another is not worth it they cost too much around 350-450

Convergance


the regulator will sometimes blow the fuse when it shorts. Hopefully the regulator will solve the problem if not you will need to trouble shoot the convergence board itself

GE 46GW947 BOWED PIC


the manual is almost impossible to find. But that chassis usually only has 1 IC that powers the convergence. Usually a STK730-020 or simallar. post the number off the IC you see up front and I will cross reference it for you and post a link where you can get a replacement

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.
