You have dust on the lcd image plate and about all you can do there is take it too the shop. Unless you have an expensive dust free enviroment and know how to dismantle the light engine...
It's not an expensive fix for a qualified shop - call around and explain what you have here in your post. A good shop will know what this is right away...

I own a Quasar SP-3235 32" TV. It has a slight green tint after 10 years of use. How can I adjust the color screens on this set? Is it a function of the remote like Sony TVs or do I need to remove


I would open it first and look, a lot of those had both the screen and drive controls on the PCB at the end of the picture tube, at least look there first.

You are dead on in looking for the screen controls, if you find one it should only be a tiny adjustment due to age and the Crt changing a bit.

My Hitachi 51f510 projection tv just started to have a problem with the color. It appears that the tint is red/pink and I have no control over it.


For me to help you (I think I know what is wrong and it is fairly simple to correct) I need to ASK you something.

If you turn the color all the way to zero and go to a channel that is in black and white, what color is the screen?

If it is red or redish a simple adjustment will correct this problem.

Is the picture with color down to zero on a black and white channel (old movies) red looking?

Before you rate this information, let me know what you find. I am in California and will be available for a while.

Hitachi RP CRT Gone Red On All Inputs!!!


I want you to do a simple visual check of something that will tell me what the problem may be.

Go to a channel that is in black and white--old movie and tell me what color the screen/picture is.

You can also turn the COLOR in the customer menu all the way off and look that way.

What we are trying to see here is if TRACKING is set correctly or has changed. If the screen is somewhat to medium reddish it may be an adjustment outside of the customer menu.

Let me know what you find--I have seen several of these where the black and white picture was somewhat red--the idea is it should be as close to black and white as possible--if red is the predominant background color the picture will look reddish.

If this has helped and you confirm the red instead of black and white picture--I can tell you a easy way to adjust this.

If this information told you something you did not know and helps you rate this solution as I do this here for free.

Take time to get used to the settings, you may think the screen looks dull at first. The truth is most people have way too much contrast on their TVs.
These settings will also work for Cable or Dish hookups, in which case you may change the Noise Reduction option to Medium to reduce signal noise.

Zenith Model SY2551S 1996 27" - Green Tint


The core problem with the green tint is the aging of the picture tube, and can be compensated a bit by using either the green drive control usually located on a printed circuit board on the neck of the picture tube or on the main chassis. There will be 3 main controls which will adjust the red and blue as well. If these controls are not present then you will need to get into the service menu and adjust it from there. Don't adjust anything else as you can make the set much worse. Also remember that in order to make these internal adjustments while watching a black and white picture (turn the color all the way down) you will have your hands and arms near live circuits that could shock you and cause injury to yourself as well as break parts inside the set when you pull back after being zapped (voice of experience here) Of course if you can do all this by the service menu then you won't even have to remove the back of the TV.

Green tint I can't seem to fix


Hopefully someone on here has a manual and can tell you exactly where the tint controls are. Also need to try adjusting the color level, turn it clear down so you have a black and white picture.
Is the picture still green over the screen with the color control
set clear down to black and white? If it does, you might
have an issue with the green gun going out or problem in the
circuitry to it.


By the way, the best way to adjust the picture settings on a
tv are to first turn the color control clear down, then adjust
brightness and contrast for best black and white picture, then
bring up the color level to where it should be and adjust the
tint for best red/green ratio.

it depends on what your using it for, adjust colour tones to what you think looks natural, contrast between 80-90, keep sharpness below 30. just have a play around till you find what best suits the source material.

Screen Green Tint


Turn down your color and see if the screen has a normal black & white screen. If it doesn't then the CRT is bad (picture tube). If it is black & White then you have a either lost your red or blue.That problem will be in your video driver circuit of which a service center can handle.
