Screen is now a weird color

Sounds like you are using an analog standard VGA cable interface. Since the menu has the correct coloring, it is not the monitors fault. Check the connections of the video cable at each end to ensure they are tight and not kinked. If they are ok, try using a different video cable. If thew problem still exists after that, it is probably the video card in the computer.

In those sets there is what they call color wheel and it could be on its way out it sounds like its stuck.or not working prop in any case you need to bring it in for service place

The color signal consists of Red, Green and Blue. Those three colors, at various degrees, make all the other colors on your screen.

If you have a BRIGHT green screen it's best you don't operate your set.
If it's just tinted green then there is a problem on the CRT (Cathode Ray Tube) drive board. Do check your "tint" setting and see if someone misadjusted it. If that isn't it then you need to have your set on an electronics bench and get an estimate for repair.

One color plug in the back was unplugged - Since the TV had not moved we didn't think to look for that. The cable bundle must have been bumped causing the problem - I feel a bit silly that I hadn't looked for that. Thanks for your follow-up.

Take the monitor back, it's failing.

I had similar problem: everything muted and with brownish tint. Tried everything, finally discovered that I installed wrong cartridge: 6PC instead of 6C. The "photo" cartridges are pretty much the same, make sure you have the right ones: 6C, 6M, and 6Y.

The problem might be in the cable. Try to reconnect it to your machine. Also try to set your color settings on the monitor itself, so that all the colors are equal.

White balance settings may be changed. Go to the menu select WHITE BALANCE then select AUTO in it , then OK then return, now try.
