I finally had my 8 year old 55" Hitachi Projection tv fixed (needed a new blue projector). Lately, whenever a bass note hits when I'm watching a movie, the picture turns Black and White. Then when another bass note hits, it will go back to color, or when I nudge the TV it will go back also. What could cause this? Could it be a loose connection? Where would that be?
BW TV: Try upgrading or replacing your patch cords between your video delivery system to your TV. Either that, or try watching a lot of AC/DC videos with a lot of cool B&W-to-color special effects on your Hitachi.
