I have a 32" Westinghouse HD TV and I have been playing my 360 through the component cables with no problems. However last time i turned my 360 on the tv said invalid format and stayed with a black screen. I switched the cables to the regular A/V cables and that worked but once again when i switched to the component i got a black screen and invalid format. I have no idea how this would just stop working or if its my tv or 360? Any suggestions would be greatly appreciated.
