Start-up confirmation reception failure.  Flashes twice

(High speed)

Start-up reason confirmation from the main CPU cannot be

received.

(Startup communication until start-up reason notification command is not received.) => Main CPU start-up failure or monitor microprocessor reception failure.

Regular communication failure.  Flashes 3 times

(High speed)

Regular communication that is performed at 1 second intervals in the normal operation is interrupted. => Main CPU operation failure or monitor microprocessor reception failure.

Other communication failure.  Flashes 5 times

(High speed)

When a request (PM_REQ=H) is sent from the main microprocessor, the request command is not output from the main CPU, etc. =>  Main CPU operation failure or monitor microprocessor reception failure.

Monitor temperature failure.  Flashes once

(High speed)

If the panel temperature is 60°C or more for 15s or more in a row, CAUTION appears on the OSD (flashes in red in the lower right screen).

If the panel temperature is 60°C or more for 25s or more in a row, error standby is activated.

LED flashing specification at the time of the error (LC-80LE645E/RU,646E/S,648E)

Display method

LED that can be used are only one of the central icon (Emblem Unit).  This expresses the error situation by combining blinking at low speed and blinking at high speed.
• For this model, the blinking pattern displayed first is only a low-speed blinking.  This expresses a rough content of the error.
• For this model, details are displayed by a high-speed blinking by pushing remote control MENU key.  This expresses details of the error.
Details are distinguished by the blinking frequency.
• It doesn’t return to the outline display again (blink at low speed) by pushing the MENU key (The toggle is not done).
Confirm “MONITOR ERR CAUSE” of the adjustment Process mode, when the error doesn't reproduce by having returned from the error.
• The process of the upgrade is expressed by the brightness of point LED that smoothness changes.
• The upgrade completion is expressed by the LED brightness that changes in a staircase pattern.

MONITOR ERR STBY

Communication/Power failure detected by the monitor microprocessor (IC2001) is stored on EEPROM, states can be confirmed in the adjustment process mode.
