A green glow sounds more like a coolant issue more than convergence. Is your TV a phillips or magnavox by any chance? Please reply to this same post and let me know your model number.

Pictur is fuzzy and green asround all charactures


If the Green appears to be " Glowing" around objects and the color tints are all wrong then its most likely a CRT coolant issue. If the picture appears as 3D with a possible arc in the screen then you can assume its a convergence issue.

Sony KP-41T65 41" rear projection tv with convergence issues on part of the screen. And screen is generally slightly blurry. I received this TV already broken (had the red blinking light issue) which I...


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

Convergence problems are very common on all Projection TV sets including Sony,Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit wiith instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms
  • Screen Looks 3-D
  • Colors wont align
  • Screen may look distorted or warped
  • No Audio/Video - makes a chirping sound.
Problem #2

Another common problem is dull or washed out video.
Your TV may have one or more of the following symptoms....
  • Dull looking picture
  • White looking picture
  • Halos around objects
  • Red/Orange looking picture

I'm having a problem with the color green being distorted on my TV. Is this a color tube issue, bulb issue, lamp issue?


This is a picture tube type TV. No lamp.
You don't describe the distortion.
A colour green picture that is twisted and shifted away from the other colours is a convergence problem. see Projection TV Convergence on this site.
If the green is smeared, out of focus, larger than the other colours like a halo around objects, things like that, it is the green picture tube. Sony has discontinued most of the picture tubes so you may not be able to get this fixed.

It has a slight green hint & a white glow around people


Your TV most likely has one or more possible problems.

Problem #1: Convergence Chip Failure ( common 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 problem.

You need to replace the convergence chips and convergence resistors. Check the site www.TvRepairKits.com. They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. 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.

Screen hazzy and issue with blue convergence


bad convergence would cause show to look as if it was supposed to be a 3-d movie, if a bulb was going out then people would look purple blue -green,or some other off color, so likely the green bulb is going out from the color of the people you described.
