HI Oscarflores5;

You might need to replace your STK ic but before you do that you can try the manual adjust. First you pop off the speeker cover then un screw the 4 to 6 screws holding on a black cover about 2 feet wide and 10 inch's tall it verys but is easy to find. once you pull off the cover you will see a black box with 6 tuning Knobs in the top left corner. If you hold a flashlite up to it you will see a R,G,B above or below three of the Knobs.
You can adjust the focus for each tube.
I would have your tv on your basic + convergence setting as it gives you the best screen for doing your focusing.
If this fails to fix the situation the you can replace the STK 393-110. They cost about $10 and you will most likly need two. Try Bluestar.com.
Make sure you replace with sanyo ic's or you will be redoing this in a few months.
just key in you TV model "# stk replacement" you should find lots of step by step instructions. It takes about a hour.
Good luck
Buck

If you mean smearing when you say shadow then your problem may not be the convergence. The blue tube may be faulty(weak), try to play with the contrast and brightness levels and if that smear varies with the adjustment then your problem is most likely the tube, in some case there might be a problem with the screen supply(voltage) or the drive circuit. good luck

SOURCE: Mitsubishi medallion VS-60719 with convergence

Yes, this model uses a single STK-393-110---IT IS A 2001 MODEL.

If I remember it correctly the IC will be on a huge metal heat sink on the far left side of the set (as you look from the back) there is also a small IC on the same heat sink.

Not the most easy set to do this repair on and if you have a problem with the blue--it may not be the chip.

I have seen 3 or 4 of these where the problem was broken connections on a 10 or 12 pin plug at the left front of the board----

The way someone would pursue this is get the entire chassis up so the bottom of all the boards faces the back of the set--The plug goes to the convergence yokes this set uses---I have seen several where several of the pins had broken loose from the circuit board--normal with expansion etc.

If I was repairing it I would look at the plugs in that front left area FIRST! The last one I fixed had bad connections on TWO plugs---with the board up they will be clearly cracked or ringed--broken loose--if the set for some time would be good and then go bad it is most likely a solder problem.

Resoldering is much easier than replacing that chip!
if it is not resoldering the Chip can be purchased on Ebay for about 14 dollars plus shipping.

If you have someone come out tell them what you know---The plugs (as you look from the back) are up front and towards the left side

Mitsubishi RPTV has a blue shadow/image alignment problem


Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projeciton sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you are handy and can follow directions. You can get complete repair kits from TvRepairKits.com or click here. They have put together DIY repair kits that include the OEM parts and step by step photo instructions for each repair. If you are not handy or can't follow directions we would suggest calling a shop.
