I own a 7 year old Crosley (Philips-Magnavox) 55" projection TV model # 55CP40C104. I recently attemted to connect the TV to my DishNetwork set top box with a set of component video (YPbPr) cables. When I switch to the input for this connection, the screen just becomes a scrambled, garbled mess. Is this a compatibility issue or is there something I can do to correct this??

Thanks
