I have a new Insignia 50 inch TV. Model NS-50DR620NA18. I also have a new Sony Blu-ray player, model BDP-S6700.
No matter which HDMI port I try on the TV I get the message "No Signal Is It On?"
Well yes, it is on.
Occasionally, if I turn the Sony off and then back on I get a Blu-ray screen, and a message to press the * button on the TV controller for options. This screen only lasts a few seconds before the "No Signal" screen returns.
