CYBERSHOT DSC-T1 ALL WHITE LIGHT TURNS PINK, WHY???

Please anyone help!
My Cyberwshot DSC-T1 is already 4 years old. I don’t know if it is going out.
In all of the setting except 1 ( ) the white light on daytime is pink.
Only the high speed shutter with Golfer icon will take a good pic out doors.

Any ideas
my email is reroll@comcast.net

thanks
