Q: Why doesn't my remote work?
Possible Causes:
Weak batteries are almost always the problem.
Trying to operate equipment other than your DIRECTV Receiver?
Remote sensor on the receiver could be blocked.
Solution:
Check that nothing is between the remote control and the remote
sensor.
Make sure the remote control is in DIRECTV mode. Slide the MODE
switch on the remote to the DIRECTV position so the remote will control the DIRECTV
Check the batteries in the remote control. They may be weak, dead
or installed incorrectly. Try replacing batteries.
If you're entering a channel number that is less than four digits long,
the receiver might wait two seconds before tuning to the channel.
Press ENTER after entering a channel number to tune immediately.
If you are trying to operate a device other than the DIRECTV DVR
that you have programmed the remote to control, make sure you
first slide the MODE switch to the mode that is programmed for that
device (AV1 or AV2). The indicator light for the component you're
trying to control should light up when you press a valid key for that component. If it doesn't, make sure the MODE switch is in
the correct position.
