Whites are real bright and has an orange color

Well the color has nothing to do with "perfect picture RESOLUTION". Go into setup and try to adjust the colors...or amount of color...same with brightness. Also check any automatic setting for the screen or picture.

Just replace the T-con board

To adjust color first of all set contrast and color controls to minimum,adjust the brightness to see clear picture than add contrast to get perfect black and white picture than add color to it for a good quality color picture.

Contrast and brightness won't fix it.You are on the right path though.You need to search around for a color adjustment.You should have numbered scales for all 3 primary colors to adjust.It should also be somewhere under the picture option.Let me know if you need better instructions.Good luck!

The TV will not let you set brightness, contrast, color or tint in the preset modes like Vivid, Movie, Standard etc. Look for a mode that says custom, user etc..

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.

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.

Its a slight possibility that a 2.00 Part called a capacitor could be bad on the screen drive voltage source. But most likly it sounds like the Picture tubes are comming to the end of there life expectancy. If the crts are weak there is a crt rejuvinator that could possibly clean the grids off each color gun. But this is a crap shoot, as sometimes it destroys the tubes. These type of repairs are not for the handi-man or a consumer to do. There are no real user replaceable parts inside so unless your able to solder and know the HI Voltage saftey issues, you should call a pro to assist you in this repair. Good Luck
