What Causes Dvd To Play In Black And White Black Flashes While Watching Dvds?

Black flashes while watching dvds? - what causes dvd to play in black and white

Whenever I see a DVD with my 5 disc DVD changer that's part of my surround sound system, a black flash on my screen once a minute. The sound to play through the black flash, and video is not endings, but the flash is pretty boring and takes about one second. Sometimes the brightest pixels are (white and green, usually), flashes the black in the form of images on the screen, just before the flash. Who knows what causes this problem and if there is a way to fix it. I tried to get a new HDMI cable, but nothing changes.
