Color problems! Our color has become 3D - red and blue are separated, especially on the right side of the TV. I know it's not a lamp - any suggestions on what it could be??

    I have the same problem, and when I go to the advanced convergence grid it's really distorted on each side but normal in the center

  • s-jarvis Jul 07, 2008

    have a Mitshubushi WT-46809 rear projection TV. It was manufactured in 2002. When viewing the TV the picture shows ghost images and red,blue, and yellow lines. This is an intermmintent problem. Sometimes the problem goes away. I did a factory rest on the convergance. I also tried to set the convergance myself but it will only allow me to move the tartget up and down. I went into the advanced option and the grid was everywhere - again it would not let me move the lines from side-to-side. Can I fix this myself?

    Thanks

If it caves in INTERMITTENTLY and you have a 3d effect you may have problem with convergence. you would need to resolder or replace convergence ics. STK392-570.
you would need to have some king od skill soldering and
unsoldering parts.let me know if you need more info.
if you take the speaker grill and the wood board behing it,(4-6)screws you will see the board in the center,big metal heatsink.
you would need work from the back in you want to replace them.

Kp-65wv600 looks like I'm watching a 3D tv but not tv isnt 3D It has a blue, green and red out line behind the person could it be the lamp light and if so what color


Hello sburdano,
Welcome, and thank you for using FixYa!
To answer your question: The colors are all working, they are just out of alignment.
Judging by what you have said hear, I would assume that the television have been moved, rather roughly, or bumped into rather abruptly. The color wheel will need to be re-aligned to the lamp and lens. You need to find out what your local TV Repair shop would charge for re-tuning.
Have a great day!

Re: Toshiba 65 in Cinema Series - 12 years old. Color Separation. Green bow at top center of screen, red and blue double images tilting upwards toward sides. Sometimes clears unassisted after set has...


projection TV sets have two very common problems. One is convergence ( 3D/Warped video) 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. 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.

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.

Your TV most likely has one of two possible problems.

Problem #1: Convergence Chip Failure ( common problem )

Here are some of the most common symptoms and example photos of a convergence problem
  • 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.

Here is a quick test....

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

Try to adjust the red and then the blue convergence.



You should be able to move them up, down, left, and right.

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

2c07611.pngSolution #1

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.


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.

Picture has become distorted, especially towards the side of the television. The colour filters line up towards the middle of the television, but become distorted towards the sides.

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.

Convergence problems are very common on all Projection TV sets including Sony, Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit from the link below.

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 - TV may also make a chirping noise.

You should be able to move RED and BLUE in all directions - up, down, left, and right.

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 solution

Convergence


Then it is likely the pre-amp transistor that controls the red is shorted out.
hopefully you have extended warranty.
there is a trick to likely get them aligned anyway if this is a tube tv.
