Default Color temperature problem with Dell P1110

Hello,

I've got a Dell P1110 that came to me with multiple problems. It had the
well-known excessive brightness problem which I cured using the hack of
bridging an additional resistor across one of the two 10M resistors that
lead to G2. It also had a slow warmup...around 60 seconds before a picture
would appear. This was cured by replacing C685 on the power supply board
which was high ESR.

The last problem I haven't been able to figure out yet. I belive this
problem started when I used the "color return" function available from the
user controls, but I can't remember for sure. Basically, the front panel
brightness controls have little or no effect on brightness, but they do
affect the color temperature. A low brightness setting gives the screen a
blueish tint, while a high brightness setting gives the screen a reddish
tint. The contrast control seems to work fine from what I can tell.

If anyone has any ideas of what may be wrong, I'd be interested in hearing
them. Either that or can I "undo" the color return function? i.e. Is
there some "reset" I can access through a hidden menu or something?

Thanks,
Mike Cencula
