The color on my television keeps turning black and white....?

Question

and then it turns color again after a few moments. It's about 6 yrs. old. Standard tv.

Answer 1

A couple of thoughts:

The tuner could be a little off channel. If you have a fine tuning adjustment, play with it.

There is sometimes an internal sensitivity adjustment for color. This is so there will be no traces of color in black & white programs. It may be at too much of a color-kill setting.

Answer 2

it might be Switching to PAL and NTSC so it causes black and white

or get a new TV
