I have an LG 50 PX5D, DirecTV and a Rotel CD/DVD player, rdv-1040. I have the red, blue green wire connected b/w the DVD player and the TV, Component 1. I play the dvd and hear the movie thru my surround sound system, but no picture. It just flashes on the screen "invalid format." It was all working when it was another TV.
More aboutinvalid format
Be carefull RGB is Not component, verify that rgb from the dvd is connected to the rgb inputs on the TV. Where is the surround sound system getting it's input from?
