Sony XBR-77A1E オーナーマニュアル

There may be poor contact between the battery and the remote control. Remove the batteries, then
insert them again.

Point the remote control at the remote control sensor located at the front of the TV.
Keep the remote control sensor area clear from obstacles.
Fluorescent light can interfere with remote control operation; try turning off any fluorescent light.
When you unplug the TV and plug it in again, the TV may not be able to turn on for a while, even if
you press the power button on the remote control or the TV. This is because it takes time to initialize
the system. Wait for about 10 to 20 seconds, then try again.

When your voice is not being recognized, make sure to activate the 

button on the remote control

with the 

button, or register the remote control with the 

button to your TV. To confirm these

settings, press the HOME button, then select [Settings] — [Voice Remote Control]. The 

button

may not be available depending on your supplied remote control.
