Intermittent color loss

I’m having trouble with the color going in and out on my Dell monitor. The back light will flicker and dim a little and the red & green will go monochrome. All I’ll have is blue. This may last for a day or a minute. It seems like a power connected problem either in the house or computer--something like a compressor in an AC unit coming on and the house lights will dim for a second—or a brown-out. It is also 4 yr. old—and that’s why I’m thinking Backlight problem.

I’ve been through the usual steps. Dell does not support this model anymore.

I have set the timing down to 60Hz and adjusted color and brightness. Done the auto adjust.

Hoping someone has been through this particular problem or might know the life expectancy of this model or backlight with 4yr. moderate use. 21” Dell UltraSharp.?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /> 

Thanks very much,
