1. Connections

Problem

All indicators go out although

the unit is turned on (it may

seem that the unit is turned

off).

The unit does not function

correctly.

The unit turns on by itself.

The TV's 3D glasses do not

work.

The unit cannot be operated

with the HOME THEATER

CONTROLLER app. (The

screen on the Bluetooth

device will not exit the app's

demo mode.)

Cause

The unit is configured so that indicators do not glow or

flash unless the unit is being operated.

The internal microcomputer is frozen, due to an external

electric shock (such as lightning or excessive static

electricity) or to a drop in the power supply voltage.

Another Bluetooth device is being operated nearby.

The unit is blocking the TV's 3D glasses transmitter.

The Bluetooth device on which the app has been installed

is not connected to the unit.

Remedy

Use the DIMMER key to select the desired brightness (p. 29).

Unplug the power cable from the AC wall outlet and plug it again.

Terminate Bluetooth connection with the unit (p. 32).

Confirm the position of the TV's 3D glasses transmitter, and

position the unit so that it does not obstruct the transmitter.

Establish a Bluetooth connection between the Bluetooth device

and the unit to use the app (p. 31).
