PROBLEM POSSIBLE CAUSE REMEDY
Power failure
Check the power supplier if the power supplier is supplied to the
unit. Check the power cord and correct if damaged.
Transformer (Discharge
transformer before testing)

transformer. Replace the transformer if either of the input/output is
open or the transformer is damaged.
No power display
on panel or any one
of the buttons
failure.
Display board or main PCB
failure
Check the voltage on display board. Replace the display board if it
is +5V else replace the main PCB.
Remote control
failure.
Battery failure
Check the voltage of battery. Replace batteries if the voltage is
lower than 2.3V.
Check voltage. Call an electrician if not within limits.
Test capacitor.
