Pink-ish or orange-ish screen indicates a bad bulb in the lcd.
Does the laptop turn completely off? Or does it stay on and the screen is what goes blank?
If it's just the screen going blank, considering your description of the color shade, you would need a new screen. Try using an external monitor and see if it boots ok.
If the laptop shuts off completely, not so much a heat issue that early in the boot. It would need more time to get hot enough to shut off. Could be bad ram? Try using one stick of ram at a time. Could be bad power adapter, is the battery any good?? Several things could be causing it to shut off.
