    I have the same problem, my blue is out of focus, so a service call is in order...any idea of the cost to replace, if it can't be fixed

  • jolly_guy Jan 07, 2008

    I came to this site because the blue on my TV is out of focus - the other colours are fine.



    Wanted to know if it was worth repairing or if the TV had come to the end of it's (too short life)

Projection TV sets have two very common problems. One is convergence ( 3D/Warped video) the other is CRT fluid ( Dull Video). Below are more details for both items. Also, complete repair kits with instructions and repair support are avail from site such as www.TvRepairKits.com

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.

For more more examples and find a fix using this link on Fixya http://www.fixya.com/support/r2861467-solution_video_looking_whiteish_dull

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

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.

It won't turn on


It could be the lamp, the ballast, or the color wheel. Last resort would be to check the power supply to the TV.

Red blinking light


It's most likely convergence -- the small board up and to the right inside the back of the TV, which has two large amp Ic's attached to it..
Unplug the +/- 20v line on the fron left corner of that board (red in color) and then try and power on the set... If the set comes on the board needs to be repaired and it's an easy unplug and two screws that mount it inside.

Double vision on my samsung HDTV 1080i


If one or more of the colors, red, green or blue have separated from each other and you can`t correct the problem using the convergence procedure as described in the users manual, that would indicate you have a convergence problem. Bad solder connections on the convergence output chips are common. If the set had a rough ride down the stairs while moving, that may have facilitated in exposing a preexisting condition. However, the most likely cause is the natural failure of one of the convergence output chips and or related components and not the move. The fix is to have a qualified technician address the problem. This is not a do it yourself job.

Blue and Yellow doubles


Well, fortunately the television that you purchased has an auto-convergence feature. What is happenning is that your color lamps are misaligned, did it get moved at all recently? Anyway, in your menu you should see a "Convergence" menu, and inside that menu, a section called "Perfect Focus". Run Perfect Focus in this sequence: Green --> Red --> Blue After that your picture should look great, if not try tinkering with the manual adjustments on the "Convergence" menu.
