Facing TV Problems? Ask a TV Technician.
Bought the TV new last June (2012). Problem occured last night when I was turning the sound down and it seemed to slip buttons or something (I wasn't watching my hands) and suddenly this "Component/AV (energy savings mode)" message comes on. I tried shutting it off with the remote the usual way and restarting, and that didn't work and I sent to bed. Tonite was the first time I tried since then and I spent half an hour turning it on and off and unplugging it, etc. When I turn it on it seems like the cable box is clicking on as usual and the red light is flashing as usual. Then I hear another click and it's like the cable box turned off. Light is off too.
Yes, I have the original TV remote, but I use the Xfinity remote. We have the Xfinity cable box/DVR plugged in and a transformer, but no DVD, radio or other hook-ups. It is connected by an HDMI cable.
I think it worked! Thanks.
