I recently bought a new blueray player (LG). For some reason the signal from the player isn't being received by the tv (LG also). it states "no signal". I have tried changing HDMI cables. Using different HDMI ports on the TV. All of the ports on the tv work as demonstrated by the Roku box being recognized. the only thing that I can think of is that the bluray is sending a higher definition than the tv is capable of. But I would think that the blu ray should auto-detect the definition capable by the tv like the Roku does and downgrade if necessary? Any ideas?
