It may be the fluid in the CRT or convergence chips are bad.

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 prblue color is ober screen - 2c07611.png/>

The colors are not sharp any more and they all blend in together, its either too much red or too much green or blue what can be the problem?


manual convergence should fix the problem if it does not the set most likely either has a bulb burnt out or a bulbs power / focus needs to be adjusted by taking off the panel and finding a 6 screw control panel

...
...

should look like that 3 screws in a row on top of another three screws each of thees control the power and focus of each color this is a somewhat delicate process and is a huge pain on larger tvs that you cannot completely see the picture or color while you are directly under in front of it so I had my gf come in the room and sit across to let me know which color was doing what if you dont have someone you will need to check after each adjustment

now the diagnostic
as i said each screw controls a colors power and focus the focus is used if you see an outline of a color around pictures if everyone looks like a dead jedi with a blue aura around them the blue focus needs to be adjusted and so on for each color if you skies or blue screens seem feint your blue power probably needs to be turned up and so on for each color

if through the course of this you can see the bulbs and notice one is out your probably looking at dealing with the color issue until the time you can purchase a new tv as the cost of the bulb and the technician needed to install it as they are wired to a circuit board and requires technical knowledge and tools


hope this helped

Odd picture....


Yes, your convergence is off. There is a function in the menu for adjusting these propoerties. It is supposed to be done monthly but rarley is. If it is ten years old or more, the cooling fluid in the projection tubes can get low, causing fish bowl effect. Not a cheap job and time intense. Try adjusting the convergence first. It gives you three screens to aling each color then save. Good luck!

Your TV most likely has one or more 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.

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 of a set that needs the fluid changed.

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

Blue aura at bottom of screen


Check 2 things.

First, make sure the lenses, mirrors, and back of screen are spotless. Second, look into the CRT's when the set is running. There is a real good chance cooling fluid leaked out or got cloudy. It's supposed to be a clear oily fluid (a combo of glycerine, water, sometimes methyl alcohol and preservatives) and will be around the tube and chassis if leaking. Rebuilding the assembly is possible (Magnavox had the same problem, as they were a Hitachi chassis), but the CRT is usually damaged. If I have to rebuild them, all 3 are done in one shot - new fluid, seals, filler spout.

Besides that, the tubes are cheap and lose their sharpness with age (gets gassy). Had real problems with that and the only correct solution is to replace all 3 tubes. You could cheap out with one tube, but setting the color balance (grey scale) is often difficult if not impossible.

Good luck,
Mark
