When my 65 inch Mitsubishi tv is on for about 10 minutes the colors get al blury and almost looks like 3D without the glasses.It is nine years old Model number WS-65819.It doesn't clear up


Your Convergence ICs are likely failing or it is a bad solder joint related to that area. It is very common on rear projections. The solution is to replace the STK chips, check fuses and the resistors next to the STK chips. Replace as necessary and re-align via the service menu. It is about a $300 repair at a tv service center. You will need the service manual if you decide to do this yourself.

Try This:
When you notice the symptons Use this simple test to verify.
Go to the users menu on the tv.
Look for the converge option probably under setup or video setting. Converge is short for convergence to align the red and blue colors to the green color.

If you cannot move the red either horizontal or vertical, then the STK chip has failed for red section.
If you cannot move the blue either horizontal or vertical, then the STK chip has failed for the blue section.

If you can move both in each direction then the problem is something else.


Note if one STK chip fails, you replace both regardless. There may only be one STK chip in this set. If there are two, they will be right next to each other.

Red & Green stuck together, Green is full wide. - accidentally posted this in Flat Panels and can't change it.--- I'm working on a Mitsubishi WS-55819, (correct model # this time) that replaced...


Between the fuses, resistors, and the IC packs I think you've done well. Your going to have to recheck your soldering on those lands at the IC's pins, or replace the defective (new) packs.

Can not align red even though convergence board WS-55819


Did you replace the center board with the STK-392-570 chips or the Digital convergence board mounted on it?


98% of the time if you have a convergence problem it is on the center board---the small board on the left under the metal shield box stores and controls the convergence of this set.


WHICH DID YOU REPLACE?

I am here to help----I have fixed hundreds of Mitsubishi sets with convergence troubles.

Mitsubishi WS-55819 has double vision screen with faded red and green colors. Any idea of a solution?


Sounds like bad convergence IC's; this set uses two STK-392-570 IC CHIPS; both should be replaced and the blue 3.9 ohm resistors in front of them should be checked. Get someone who has done this repair on this kind of set before--it is usually not something for a do it yourself person; the middle pc board needs to be removed to safely replace the chips; then the set needs to be adjusted in the regular and HD modes. If this is helpful, give me a vote. if you need more direct information email me: etower.766@netzero.net

Mitsubishi WS-55819 Won't turn on


If F9A04 and F9A05 are open the convergence ICs will need to be replaced as well as the two pico fuses. You will need two STK392-570 Convergence ICs and two 5 amp pico fuses. You ca get the replacement parts at the following link with free installation instructions. heres thelink.

Can the WS-55819 be reset through a reset button?


Code 22 is short protect. Recheck your work. Did you check and replace open fuses and/or Convergence IC's. The Conv. IC's normally open at least one fuse when they go out.

Convergence ICs are bad need to be replaced. You will need to replace both of them also check the resistors right next to the IC often 1 or 2 of them burn out when the IC goes.
