WHAT TO DO
Check the connection of the external power supply unit at the wall
socket and ensure it is switched ON. If it is connected correctly the
Green power LED on the power supply should be lit.
Check if the power connector on the Set Top Box's rear panel is
securely connected.
Check if TV and Set Top Box are "ON" (not in standby mode).
Check that all the cables connections to the Set Top Box and
TV are secure.
Check and adjust the direction of antenna if necessary.
Check that the TV has the correct input source selected
(TV, PC, AV1, AV2, HDMI1 and HDMI2 etc.)
Check the mute button on the TV or Set Top Box, to restore the
sound press the mute button again.
Check the volume is not turned all the way down. To increase the
volume, press the "Vol+" button.
Check connection of the Audio cables to the Set Top Box and TV.
Check if TV and Set Top Box are "ON" (not in standby mode).
Check that your RCU Standby Key lights up when a key is pressed,
if not change your batteries
If the RCU Standby Key lights up RED:
Check that there are no obstructions between you and the
Set Top Box, aim directly at the Set Top Box and not the TV and
then try again.
If the RCU Standby Key lights up Green:
Un-pair the remote (see instructions in Section 7 of this User
Manual - "First time start-up of the Set Top Box"). Thereafter the
RCU should light up RED when a key is pressed and then the
RCU is now in IR mode and requires direct line of sight to the
STB when pressing keys. See above procedure to troubleshoot
(Go back to your Menu Setting and re-pair your remote after it
starts working fine).
Check and adjust brightness and contrast to a lower level.
