A blank screen means that it's not receiving a signal at all. This is usually caused by the HDCP in the game console.
The HDCP is in the console - and the television will not bypass it. Was it updated recently?
hi, my plasma tv (model no: PL42C91) does not want to enable hdcp, it use to work before but now when i try my ps3 it comes up with a blank screen but you still hear sound and with the xbox 360 it display normal in games but when you try to run a dvd it says no secure hdcp detected. how can i rectify this problem. p.s this tv only has one hdmi port
