The front panel LEDs provides an indication of the set’s operation, and the possible cause of a malfunction. There are two front panel LEDs, “Power” and “Status.” The LED display shows the current status or indicates a possible malfunction. If an abnormal condition is indicated, proceed to the Error Code Operational Check for more specific information.
Power LED [Normal Condition] | Status LED | Condition |
Off | Off | Off (Standby) |
Fast Blinking Green | Off | Initialization (40 - 60 seconds after set plugged in or System Reset) |
Green | Off | Power On |
Slow Blinking Green | Off | Power On Timer is set |
Abnormal Indications | ||
Off | Yellow | * Temperature high – room hot. * Laser unit temperature is abnormally high. * Optical fiber temperature is abnormally high |
Off | Blinking Yellow | Cover-back (top/bottom)is open. Yellow Laser unit is not assembled completely. |
Off | Red | * Laser unit failure * Laser abnormal brightness * Linear motor failure * Communication in laser unit failure Chassis side failure *Communication with laser micro fail * Communication with engine fail * No Lamp-EN, No ASIC-ready * DVI cable disconnection Circuit failure (short) |
Off | Blinking Red | Fan Stop (DMD Fan, Fan in laser unit) |
When the Status LED indicates an abnormal condition, perform the Error Code Operational Check.
To activate, press the front panel INPUT and MENU buttons at the same time and hold for 5 seconds.
The “POWER LED” will then flash denoting a two-digit code.
- The number of flashes indicates the value of the MSD (tens digit) of the Error Code.
- The flashing then pauses for approximately 1/2 second.
- The LED then flashes indicating the value of the LSD (ones digit) of the Error Code.
- The Error Code is repeated a total of 5 times.
Note: The TV must be in “Shut Down” and not have been switched Off, to perform the Error Code Operational Check. When the TV is switched Off, the code automatically resets to “12” No Error.
Note: Use the front panel buttons, not the remote control.
Note: If there is no response, the front panel may be locked by a V-Chip setting. To unlock, press and hold MENU for 5 seconds.
