Green tint I can't seem to fix

Go to menu, picture and adjust as desired

The set should have in the on screen customer menu settings for brightness, contrast, color, tint etc.

If in doubt consult the owner manual which will have instructions.

Hi:
You may have a problem with the inverters in the unit, they are responsible for lighting up the back panel. Check or have checked the power supply voltage to the inverters, should be around 18-24 volts DC. Also leaky capacitors on the power supply will cause this issue as well as leaky or puffy capacitors on the inverter.

It sounds like you may have issues with your main board

Have you turned the controls from one of the presets? Presets are Vivid, Movie, etc. Most sets have to be in Custom or Customize to adjust the controls, likely on-screen with one of contrast, brightness, color, or tint selected. If those are horizontal bars then up/down selects which and right/left select decrease/increase or red/green for tint. Start with 50% if no reset (0% for R/G) or start with the non-Vivid settings. Consult AVS forums for you model to get better settings. Rules of thumb: Brightness should be as dark as possible without losing gray scale at lowest part. Contrast should not be so high that whites bloom or make it hard to see. Color should not blow out any color nor be unnatural. Tint is best judged on flesh tones. -Ken

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.

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.

Hi. When TV has one color only, Unplug CRT Socket. if voltages for cathodes within 10% of each other, Problem is with CRT. check green video amp on crt socket, it may be shorted or leaky, if ok have crt checked for short involving the green cathode.
