Samsung HLR6167 keeps flickering on bright scenes

My Samsung HLR6167 flickers when it gets to a bright scene. This only happens when using component inputs. I have an Xbox 360 and DVD Player connected using component cables. I have temporarily hooked up my DVD player with HDMI and it works perfectly with no flickering. When I switch them back, the flickering happens again. I have also bought new components cables and double checked that I have the cables correctly hooked up. I only have one HDMI hookup on my tv and my xbox 360 does not have an HDMI port so I have to hook that up using component cables.

Is there a simple solution for me without having to call in a tv technician? Even if it involves me changing out a board in the TV? Any help that could be offered would be greatly appreciated.
