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.

Picture of a set that needs the fluid changed.

You probably need to get a Sony TV Convergence Kit. More information can be found using the link below.

Convergence Symptoms:
  • Screen Looks Distorted/3D
  • Colors wont align
  • Screen may look distorted
  • No Audio/Video - makes a chirping sound.

Screen projector un aligned


Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded overs.

The colors are distorted and it seems like the only colors that really show are blue, green, and red. When you turn the TV on you can see blue, green, and red lines across the screen. The picture also...


Hi there, this is what we call in the industry convergence board failure. this board regulate the rgb and keeps everything in order so the picture looks nice and clean. when this board starts to malfunction, what you are witnessing is usually the result. I suggest repairing this convergence board. this will fix the 3-d effect.

Turned on my 31" 14 year old flat screen panasonic tv yesterday and was greeted by a very thin horizontal line of bright light. Sound was there, just no picture. Could this be a picture tube problem?


This is most likely a failure of the vertical IC. Please post the model number of the set so I can provide you with the parts details. If you can solder, you can fix this yourself.

Thanks,
Dan

Sony 65 inch screen tv


The lines you saw, i;m sure they are the ones called retrace lines but know the failure could be located on the red CRT board. Most likely the video amplifier is defective and not necessarily the CRT.
What is the model number of your TV?
