Toshiba CF3572B turn on, nothing but green screen?

Toshiba Model#CF3572B Serial#12566654 When we turn on the television the screen is green after a few times turning it off and on the screen goes to normal. Sound is normal. What could this be?
The first being the most problematic issue we also are having another with the same TV, while turning it off and on sometimes it will not turn back on, we swich the powerstrip off and back on... this turns the TV back on. We went to the powerstrip because it was easier than plugging and unplugging the TV. Thank you.
