My TV is purple and yellow?

[Phi_Khanh_P]

i change the channels and all of then work but the colors are purple and yellow i tried changing the colors on the tv that didn't work i checked my other TV (with out comcast cable box) and its fine
what should i do


comcast repair | comcast billing | comcast customer service | comcast credit

[install tech]

my guess is that it is an HD box you have.  the 5 component imputs in the back of the box or tv arent correct or arent plugged in.  Check both to make sure the color coded cables are correct in both.
