1 Answer

Sony Trinitron Color TV - KV-27TS27 circa 1991

When I turn on the TV, lines appear and the colours look like they are bleeding. I have to turn the set on and off before the color becomes normal.

Any assistance is appreciated.

My picture has broken into colour ghosting (it looks like a 3d picture without the glasses on). I'm guessing that this might be the failure of one of the colour bulbs. The wavey colour bands that I see are...

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.

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.

In My sansui k2k21 flat tv showing red colour more please tell me will i replace the eht or crt


you do not have a CRT in your flat panel set.. What you might have is your color setting to high causing the bleed or your
T-con board is bad , but first turn down your color if that does not do it have a tech replace your
T-con board

    Colour problem


    I have default settings I normally use for most sets before I begin any kind of alingment. Contrast: 90% Brightness: 45% Color: 45% Tint: 50% If the brightness is to high or the contrast to low the color is off. Check your connections, there probably OK, but, it never hurts. If the settings don't help call a local authorized servicer in your area. Hope this helps.
