    I called PTS and sent the board to them, the board can not be repaired due to the traces.

    Does anyone have a good board that I could buy?

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 WT-36809 turns on for 2 seconds and then turns off. The error code is 22. Any ideas?


Verify the model number. Some of these Mits. family have bad picture tubes, and oil spills out onto the signal board. Look inside front panel, RHS tube, look below it onto signal board. If you see an oil puddle, then tv is toast!

You have either bad convergence ICs or just bad grounds on the IC. I would go ahead and replace the ICs and check those small ohm resistors, as you have to pull the signal board out anyway. For futher instructions see the website www.TvRepairKits.com. They may have what you are looking for. Be sure you have the TV model number next to you. Thanks for asking and show a few hands of support!

not sure which part you need main board (where flyback lives) is part no. 930b903002, power board ( where convergence IC's live) is part number 930b904001, signal board ( where tuner lives) is part no. 930b905001-55. I checked with encompass.com they have all three in stock.

Blue screen no signal


You need to replace the surface mounted voltage regulator IC (small black square chip with a metal tab on one end, and two legs on the other end.) it is on the main board, right behind the signal input board. It's a BA09FP regulator IC, you can purchase this on mouser.com

it requires a bit of disassembly, but it is relatively easy to do. it is component number IC9C25. It could be bad, or just have bad connections . This IC supplies 9 volts to the terminal board. Try resolding it first.

Mitsubishi WS-55908 Convergence Issue; need IC 7A00, Panasonic MN12857k MA2


Sorry, but when the coolant leaks down onto the small signal board, that board will never work right again. The fluid penetrates the board itself since the board is double sided and has many feed-throughs. The fluid gets under the surface mount parts and just eats through the copper traces, part leads and board itself. After trying many times to clean and restore those boards, not one has ever worked right again. The boards are NLA from Mitsubishi, so the set is done.
