Re: the color is distoted light is dark and dark is light
Have you tried updating/reinstalling the driver for the video card ? If that's windows then you would have an Application Recovery wizard option to update reinstall the drivers. Open ALL PROGRAMS > open HELP & TOOLS > open Application Recovery . Other operating systems may have something similar. This may be dependent on how old the system is too as to how easy it is to find or if it exists. You may be able also to go to Acer website put in the info model etc and download driver updates from there.
a 6ya Technician can help you resolve that issue over the phone in a minute or two.

This tv has two common problems:
in the power supply (set does distotions and shakes a lot etc very unstable until the set cannot work at all). powerfully color gets back with a deep clean in the reflexion area.

Your screen mask may have become magnetized. This will require that you have the CRT degaussed. This is done with the use of a degaussing coil. you have to stand about 10 feet from the TV with the coil held vertically and moving it in a circular pattern as you walk towards the tv. Once you are about 1-2 inches from the TV stop and continue the circular pattern for about a three count then backup from the tv still using the circular motion once you are about 10 feet from the tv turn the coil to a horizontal plane and move it away quickly and turn it off. This should degauss the TV and remove the color distortion.
You will need a degaussing coil to perform this task.
