Why does the following error message flash when changing channels "The DVI/HDMI Output Is Blocked"... Press Escape to Cancel. It disappears after a second most times but sometimes it won't let me view the TV signal.
Get rid of your HDMI cable.
Thanks for the answer but I'm not using an HDMI - i only have 1 slot on the cable box and that goes to the TV I'm using the RGB cables.
Get rid of HDMI from cable box to tv.
Thanks Jim I'll try that
