Convergence IC Can anyone tell me how to locate the convergence IC on a Mitsubishi vs 5043? I'm sure it's going bad from all the information I've gathered.

Re: Convergence IC

The convergence IC's are black in color with white lettering on them and will start with STK. These IC's will be standing up and be about 2" X3" in diameter. These IC's will also be mounted up against a large metal device called a heat sink. good Luck

Mitsubushi VS-5043 Rear Projection,,, Replaced 3 Converrence IC's. Recovered green color. Red color is bowed. Cannot move red crosshais in convergence set up. Is their a way to reset? Could something else...

There are a few low value 1-watt flameproof resistors in the convergence yoke circuits. They typically range from 1 to 3 ohms. An open resistor will cause the respective color to be non-responsive. Also chack that you have the convergence yokes re-connected to the correct connectors on the board.

This is a convergence problem. The output ic needs to be replaced.

Colers not lined up

The problem with your TV is the convergence IC's are failing. This is an economical but complicated repair. Unless you are a skilled technician, I would not recommend you trying this repair on your own. For your information, the part number for the IC's is STK392-570. Hope this helps.

Mitsubishi ws65909

Yes,but first it is necessary to repair the problem = replace
both STK392-570 IC's.............Then use remote to adjust
convergence............."inside the tv" is called servicer menu = adjust after repair is complete.You can expect to replace IC's
every five years or so.......................T.

PS Try to match your problem thread model # to actual model #
ie. VS-5043 does not match WS-65909........T.

Convergence i.c.'s

The convergence IC's and fuses are not your problem. If the Sony projection set has a bad convergence IC and/or a blown fuse or fuses in the convergence circuit, the set will continue playing but the colors will not line up correctly. If the set will not turn on at all, and has no lights at all on the front of the set, the problem is in your main power supply. If the set tries turning on and then flashes the timer LED on the front of the set, count the number of times the LED flashes, as that is the code for why the set is notworking. I have found that the most common cause of the set not starting is a shorted flyback transformer.

Possible Convergence

I would suspect you have several capacitors drifting out of tolerance as they warm up. When checking for these, also make sure to change The value Of C813 (33uf 16v) To (10uf 50v) if it hasn't been done already. You'll need a technican with a capacitor meter and ESR tester to find the marginal capacitors. I doubt that any of your STK packs (IC's) on your convergence module are defective. I'm also assuming that the tapping with the wooden stick didn't change anything, otherwise a bad solder connection could be the culprit.

No Picture after it's been on a while. Audio OK.

ok you have a vert sweep problem and yes its probably connected to in a way to the "tap and fix" problem! Seems to be n intermittant connection on the vertical out put Ic or maybe even on the rgb convergence ic?? The total loss of sweep though tells me that theres two differant problems! Maybe and intemittant connection on the vert output Ic as well as bad connections on the convergence ic??.
