Re: Color balance is off. Colors change between over...
You said that when you bump the television color will change .most likely this problem is a loose connection or cold solder of the joint of the soldered part..but you said solder joint is to be OK, it seems you have the knowledge in electronics and tv cercuitry.Problem like this is in the CHROMA-BANDPASS AMPLIFIER section there is an IC there ,these IC process the color ,change this IC and make some reheating the solder in this section..

Are you using component cables into the TV? It sounds like one of the 3 video cables may have come out saturating the red colors. Check your cabling int he back of the TV, see if you remove 1 by one if that changes the colors. Each cable on its own should have a picture with either red green or blue colors. If any of them are missing the picture then the colors will get messed up when all 3 are plugged in. If you are not using component cables then check the color settings on your TV. Somewhere int he menu of the television you should have something like picture display settings that let you adjust the colors. Check and make sure that the reds are not over configured or the others are not set too low. You may also want to check that your source is proper as well. Check that other sources look okay or if it is with all different connectors/sources that the issue occurs on.
If your talikng about alignment that is done through the Convergence feature. If its the color balance youre refering too its most likley indicating that the CRT coolant needs replacment as that will make the red Tube dominate and wash out both blue and green colors untill they appear dull and dim.
This sounds like you are using a composite, S-Video, or RF cable input.
The quality of these inputs are not as capable as component or HDMI, so colors are not separated as well. Red is a color that saturates heavily and will cause bleed as well as dithering...especially intense colors (bright green, bright blue, bright yellow, bright red).
To reduce this visual annoyance you would need to soften the video output from the player (not easy to accomplish), or upgrade to a better cable connection.
Red color gun has failed, which will make the picture over saturated with the other two colors(blue,green) the bad news is the three color guns need to be replace in a set(all at the same time) because if you only replace the red it will over saturate the older blue, green guns then your picture will be mostly red.Unfortunently in most cases it's not worth the investment, better off to purchase a new tv. Good luck !
This is from the MANUAL www.westinghousedigital.com/pdf/197_User_Manual.pdf
A-1 Settings Use the Settings sub-menu options to manually adjust the display quality. Use the ◄/► keys to adjust the option level. Adjust the luminance level. Adjust the brightness to darkness ratio. Adjust the balance of the red, green, and blue colors in the display. Adjust the color intensity. Adjust the sharpness or softness of the display. Adjust the brightness level of the screen backlight.
AND this is from the troubleshooting procedures in the manual
Wrong, abnormal or missing colors
・ If any colors (red, green or blue) are missing, check the video cable to make sure it is securely connected. Loose or broken pins in the cable connector could cause an improper connection. ・ Press and select Picture | Settings to adjust the Hue and Saturation settings. You can also select Picture | Advanced to adjust the Color Temperature settings. ・Connect the TV to another computer and check if the problem is with the computer screen.
Other than that there is no mention of color adjustment
The Fuji S2 sensor is noted for this red sensitivity. Here's a few different approaches to getting the shot with the S2, all of which require some experimentation.
1. Set the "Color" and "Tone" Function options to "ORG". Underexpose the shot. Progressively change the exposure compensation downward until when checking the histogram, the red channel does not show saturation at the high end. Advantages: this is the simplest approach to getting the picture. Disadvantages: the S2 already had a fairly limited dynamic range, and this will make things worse for the parts of the photo that are not red. For the surgical setting and use of a ringflash, this may not be much of a disadvantage, since a lot of the stuff of interest will be red, and ringflash illumination generally is of lower contrast than directional lighting.
2. Set the "Color" and "Tone" Function options to "ORG". Use a custom white balance. The idea here is to have the camera adjust the red channel sensitivity itself, and leave the blue and green channels alone. To do this, start with several sheets of white paper and a red or pink marker or highlighter. Scribble with the marker across a sheet, then use that to set a custom white balance. Take a test shot of the red stuff that has been problematic, and see whether the histogram for the red channel shows that there is no saturation at the high end. Repeat this with progressively more red or pink on each sheet used to set the custom white balance until you find the custom white balance that takes enough of the edge off the red channel response. Alternative: I just tried out making a gradient across an 8.5x11" sheet of paper going from white to about 30% red saturation. I can set more or less red adjustment in a custom white balance just by pointing the camera at different parts of the page. This seems to work OK for me. Advantage: can allow the full dynamic range of the sensor to be used. Disadvantages: the experimentation period is likely to take a while to get the best results, and the final images are unlikely to look completely natural.
3. Set the "Color" Function option to "B/W". Use a green or cyan filter on the lens to cut the amount that the red color channel contributes to the final image. Advantages: this is fairly simple as an approach. A similar post-processing technique can be applied to the photos that you already have, by nulling out the red channel contribution and desaturating the blue and green channels to produce a grayscale image. Disadvantages: you lose the color information entirely. Since much of what you want information about is colored red anyway, the organs are likely to appear quite dark when only taking the blue and green channel contributions to the image.
