Color fading to black and red "nightvision" picture
Our BenQ 46w1 is having problems maintaining optimal color, it fades to black and red "nightvision" type picture.
However it does not do this during any HD program and is temporarily fixed by switching the imput.
We have changed all cables and have changed direct inputs through cable box, dvd, vcr and the wii.
Any thoughts would be helpfull.

What you are describing is a bad print head. You can try running the eliminate light stripes several times, and jet substitution, but most likely the print head will have to be replaced to remedy your problem. You can try googling. Phaser printer print heads or phaser printheads. There seems to be a secondary market appearing for those print heads. I can tell you from Xerox, if you have no maintenance agreement, they cost $750 per print head. Honestly, having worked on about every type of color printer known to man, the new solid ink phaser printers, produce a dry ink image of 2400 x 2400 dpi with ink particles that align end to end. The resolution of those printers are remarkable and can be purchased for less than the price of one of those new print heads. Now for reliable, albeit somewhat not as sharp a color image, but still exceptional, you really can not beat an HP. The ink stick technology really no longer has the color vividness advantage it initially had. The inks that align end to end, have ended that advantage and are sure a lot cheaper to operate per page.
if it is a tube type unit you may not find a new tube they are almost extinct ,
also, most tube malfunctions are caused by improper voltage, only a qualified tech should work on the high voltage section of a tube tv,,, it can kill you even if it has Not Been Plugged in for a whole year
re-post with the make and model number for further assistance
use the advanced options page and reset the factor blue and red convergence defaults then do re apply the auto color defaults color at first it seemed very red (which is good because red was the missing factor in the green picture) but after reseting all the color and tints to the normal ranges I then reset the color auto correct again and all seems fine.
