iMAC G4 pink screen of death!
There are two reported problems: The first is a complete failure of the backlight, which renders the screen black, but readable by flashlight! The second is a change in the monitor colors.
Our problem is the latter - when booted normally, the screen is a pink hue. Blueish tints seem to be present, but I wonder if this means that green has completely failed in the monitor? I've done some trouble-shooting. The bug does not appear to be software related. When booting in a text mode (i.e. single user) the screen is red instead of black and the text is white. When booting into open firmware the text is red on white.
An external monitor works fine. Does this suggest that it is not the video card or main logic board? It is either in the monitor or something between the monitor and CPU. I inspected the monitor connections - they seem to be seated fine. I have not opened the CPU to check connections there.
I like Apple products when they work. But there are three problems here: a defective product, a limited supplier of parts, and poor technical service on the part of Apple. I can't afford to "fix" a computer for $1000 with a main logic board replacement when it cost me $1200 to begin with!
