Weird DIRECTV problems? Try turning off HDMI Control

Does your TV turn on in the middle of the night? Does it change sources when you don’t expect it? Things like that can be symptoms of problems with the HDMI Control protocol that’s been part of DIRECTV equipment for about three years.

HDMI Control, otherwise known as HDMI-CEC, is a way for devices to work together. Using the remote from one device sends commands to another device over the HDMI cable. Usually it works flawlessly, turning on the TV when you power up the DVR, and setting the right input.

Occasionally, and very rarely, things go horribly horribly wrong. TVs will turn on by themselves, inputs will change, and it’s usually because of some stray command sent to the DVR or receiver. There’s an easy way to check.

In most cases, HDMI control is on by default and you probably never noticed it. To turn it off, Press {MENU}, then go to Settings&Help, Settings, Display, Video, and turn HDMI Control off.

If that solves your problem, then you’re all set. If not, it is possible yet very unlikely that your receiver is possessed. I highly recommend calling Ghostbusters.
