Poor viewing quality


By poor color quality, do you mean that if you turn the color control all the way down, the black and white picture is more like black and red, green or blue - or do you have a good black and white image? If the B&W image is good, and the TV is an old (8+ years) one, maybe the mirror inside the set needs a good cleaning - especially if there are smokers in the room. If you have a B&W picture that is tinted, then you may have to go into a service menu to adjust it back to a better picture. Hard to guess the problem without more specific description of symptoms.

Green tinted people


The only time I have had issues like this was because of the Component Cables not being in the right position (the Red and Blue connections switched), or a bad Component Cable where the Blue Connection is not receiving a signal. Swap out the cable to be sure and double check that it is properly installed. Green to Green, Red to Red , Blue to Blue.
Hope this helps,

Toshiba 65H14 is all green... Tint doesn't change it..


As TVs age, the rate at which the CRTs begin to decline in terms of light output increases. If you go into the customer menu and adjust the color setting to zero. ( no color) observe the image. Is it good gray scale? Or, is the image still green tinted? If so, its definitely a problem with the CRTs( picture tubes) You may need to just re-adjust the screen settings for the CRTs or it may be more serious, a CRT may be bad. Replacing the CRT is a job for an expert and will cost $500-700.

Greenish tint to picture


there may be a green tube issue or there could be a screen voltage or screen control adjustment issue. There is a control block with six adjustment screw inside the front panel in front of tv. WARNING high voltage exsit in this set and adjusting these controls really should only be done by a tech,....So be careful

A lot of green tint in the picture


Hi, what you do is unscrew and take off the grill, take off the black board behind it. You will see a little box for adjusting RGB you will adjust the screen rgb to get the tint to go away and have a perfect color then you will adjust the focus for sharpness. (reset the tv to factory settings before doing this so that your tint, color, brightness and everything else is in the middle.

ALOT OF BLUE ON THE SCREEN!!


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.

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.
