The color is bliry and faded . if it is a night scene the picture is really dark you can hardley see anything, depending on the pic. if a pic is blue all u see is blue. it is also bright


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. Repair kits with instructions are also avail from 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.

Screen is bliry and has a few blue lines kind of like a outline


This is a common problem called convergence, I will attach a few photos of typical convergence problems.

In your set it is a fairly easy repair but does require being able to get at the two convergence chips.

Parts cost will be under twenty dollars (I can tell you best place to find them)

If you are able to solder let me know and I will assist you.

Hi,

Yes, the screen can be replaced. The screen is comprised of 3 screens. The Fresnal Screen (inner screen), Lenticular Screen (middle screen), and the Protective Screen (outer screen). Please see below for links to these items.

Need all 3 to complete screen assembly.The only screen that is still available is the innermost screen, which is probably not the 1 you need. You will only be able to find the middle (lenticular) and outer (protective) screens from a distributor that has them in stock as no one will be able to order them from the manufacturer.

  1. Fresnal Screen
  2. Lenticular Screen (no longer available)
  3. Protective Screen (no longer available)
