DIAGNOSTIC TEST INDICATORS
When an error occurs, the STANDBY LED will flash a set number of times to
indicate the possible cause of the problem.
If there is more than one error, the LED will identify the first of the problem areas.
Result for all of the following diagnostic items are displayed on screen.
If the screen displays a “0”, no error has occurred .
The units in this manual contain a self-diagnostic function. If an error occurs, the STANDBY LED will automatically begin to flash.
The number of times the LED flashes translates to a probable source of the problem.
A definition of the STANDBY LED flash indicators is listed in the instruction manual for the user’s knowledge and reference.
If an error symptom cannot be reproduced, the remote commander can be used to review the failure occurrence data stored in memory to reveal past problems and how often these
problems occur.

 for an extended period of time.

4) Do not expose the LCD panel to direct sunlight.
5) Avoid contact with water. It may cause a short circuit within the module.
6) Disconnect the AC power when         replacing the  backlight (CCFL) or
inverter circuit. (High voltage occurs at the inverter circuit at 650Vrms.)

7) Always clean the LCD panel with a soft cloth material.
8) Use care when handling the wires or connectors of the inverter circuit.
 Damaging the wires may cause a short.

9) Protect the panel from ESD to avoid damaging the electronic circuit
(C-MOS).
