Question about Mitsubishi VS-55609 55" Rear Projection Television

1 Answer

Tv Blue Convergence separated from other colors

While watching my tv, I heard a low noise click and saw my screen gliched. Later I saw that the blue in my screen had separated. I atempted to re align then together and coulnt do it. I turned off the tv for a short while apprx 10-15m and when it got turned on it was working properly. Then apprx 25 minutes later it happened again, then after that the blue color would glich (come and go). It is working properly at this time, but I know that it will hapen again. I am almost certain that I will have to send it for repairs, but I am afraid of what it ($$$) could meam. I like my TV, I purchased it back in '03. I like repairing my own stuff (electronics, etc..) if this is reparable, can someone let me know. before I break it, Thank You.

The fix for this is by replacing two identical IC's

But before replacing these IC's technicians check small components called resistors and pico fuses. They also check for loose or cold solder connections.

    1. Remove the back cover from the TV (just the electronics cover, not
      the entire back of the TV!). Remove the black bracket that holds the
      RCA and other jacks as well as the black plastic bracket that holds the
      cables out of the way. There are different size screws used here, so
      keep them labeled or separated in a useful way.

    2. The only board you will care about for this repair is the one of
      the left side. There are a few connections between it and the center
      board to watch for, though. Slowly begin unhooking cables, labeling
      each cable and the corresponding plug-in spot on the board. Use the
      tape and marker. I started at “A” and worked my way up to “X” if I
      remember correctly, but you could use whatever pattern you like. There
      are 20+ cables (hence A – X), so take your time and get it right. Take
      pictures along the way. You will need to unscrew the vertical board at
      the top left to get further along, and you will eventually need to
      remove the large plastic “bridge” running above the center of the
      board. This one has screws at the base in front of and behind it, so
      it's a little tricky to get out.

    3. Pop all of the attachment boards off the mainboard. Press the three
      clips on the side of the board and pop it out. Carry it to your
      workbench of choice.

    4. Remove the clips that hold the ICs against the heatsink. Desolder
      the ICs and dispose of them. Since they were already dead, and I was
      fully committed at this point, I just clipped all of the IC pins with a
      small pair of diagonal pliers (dykes) and threw away the old ICs. Then
      I flipped the board over and desoldered each pin, pushing the remnant
      down through the hole so it dropped off the board to the bench. I had
      great luck with the desoldering wick, it sucked the solder right out of
      the joint and the pins pretty much fell out. Some took a little
      wiggling, but nothing was too difficult. After all the pins were out, I
      checked and cleaned the holes with the soldering iron (quickly).

    5. Flip the board back over and clean the heatsinks well. Line up the
      new ICs and make sure that the pins drop into the holes properly.
      Sometimes they get a little bent from shipping or your own handling, so
      line them up (gently). Apply a thin layer of thermal grease to the back
      of the new ICs. I spread mine with a razor blade, something that has
      worked well for me in the past doing CPU installs in computers. Drop
      each one into place, then use the clip to secure it against the
      heatsink. This will allow you to flip the board again and do your
      soldering without needing anything fancy holding things together.

    6. Slowly and carefully solder each pin. A good solder joint should
      look like a little “Hershey kiss.” Be sure not to run over onto
      adjacent pins and bridge the joints. I didn't have any trouble here, so
      I can't comment on how you would fix that.

    7. Once you're all done, clean the back of the mainboard with alcohol
      and a toothbrush to remove and flux or other gunk. Wipe it down and dry
      it thoroughly.

    8. While you're here, you might as well check the resistors. There are
      several large resistors around the ICs. Grab your multimeter and check
      their resistance. If you don't know how to read a resistor (it had been
      a while for me, too), check my Links below for some good charts.

    9. Now for the fun part-- put it all back together! Do everything you
      did to take it apart, but in reverse order. I put a laptop right next
      to me with my digital pictures on it to help, but you may not have that
      luxury. Take your time, make a checklist, and work through it. Refer to
      your pictures along the way to be sure. Try not to bump the CRT guns or
      the adjustment screws on them while you're working.

    10. Once you have it all back together, leave the back off and fire it
      up. Let it warm up for a bit and then check it out. Make sure you plug
      things in to the various inputs to see them work. I made the mistake of
      looking at the menus on screen, thinking all was well, and closing it
      all up. When I wheeled it back in place and hooked up all of my
      equipment, I discovered that only my HD input worked, nothing else! I
      had to open it back up and look around carefully until I found a small
      cable that wasn't seated properly. Once that was in, it all worked well.

    11. Don't be disturbed if the convergence is still off, it just needs
      to be adjusted (and it can be now). After a good long warm-up with
      plenty of bright colors, select the convergence menu. I reset mine back
      to factory defaults, then went through the multipoint convergence for
      both red and blue and lined things up again. You really should have the
      TV warmed up well, or the convergence will just drift off once it does
      get there.

Triple image color separation


All projection TV sets have two very common problems. One is convergence ( 3D/Warped video or dead set) the other is CRT fluid ( Dull Video). Here are more details and solutions for both.

Common Problem #1) Convergence has gone out

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. In some cases the TV will also not show any video. 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 projection 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 pics of convergence problems.


7859b01.jpg

e87380c.jpg

Common Problem #2) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

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

I was just given this t.v because friends couldn't figure out what is wrong with itl. The colors don't line up right,looks kinda blurry depending on the lighting of the program being watched. How do i fix...


According to the manual:
1) go to the "TV Main Menu"
2) Select "Screen"
3) Select Adjust Projection TV (obviously only if a projection TV).
This then allows you to adjust the TV's 3-colors. Selecting GREEN CENTERING brings up a control panel that lets you center the green projection tube on the screen. Selecting RED CONVERGENCE or BLUE CONVERGENCE lets you align the Red & Blue projector tubes. Centre the green projector tube 1st. Then adjust the red & blue until the test pattern on the TV screen appers white.
Good Luck!

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.
