The ballast board for sure. If the color doesn't come back, try cleaning all the lens elements in the box in front of the lamp. If that still doesn't restore the color correctly, then look at the color wheel.
C1440 code means that your exposure lamp has failed or the circuit that powers it has failed. The exposure lamp is the light that comes on from under the glass and scans your original. Most likely failure is the exposure lamp itself. I would say between the 2 that 90% chance the failure is in the lamp. If you want to replace it yourself the part number you will need for the lamp is 1177-7801-01. If you can not locate one reply back to me here, as I have a parts machine I could find you a lamp.
Good Luck and Thank You for using Fixya.
the lamp is located in front below the screen. there is a plastic panel to remove(full width of t.v.) the lamp is in the center held by allen head screws(replacement lamp will supply an allen wrench) be carefull not to get fingerprints or dirt on front of lamp(premature lamp failure will happen) hope this helps.

Change the whole housing, if you touch the lamp with your bare hands oil is deposited on it and it will cause premature failure. If the lamp light is lit it is a good bet the lamp needs to be replaced.
there isn't one. you need to see the menu. but what color is the led and is it blinking?
green- all is well
1 time- lamp not striking after 5x.
2 times- lamp has more than 3000 hrs. replace lamp.
3 times- lamp failure. replace lamp.
4 times- fan failure. shuts down.
5 times- undiagnosed error. possibly ballast or colorwheel.
if the colorwheel won't spin, the lamp won't light. when you turn on the projector, do you hear a high-pitched whir? if not, the colorwheel needs replacing.
