LC-40/46/52/60LE810UN (1st Edition) LED flashing timing chart at the time of an error 100ms 400ms 1.6sec 1) Slow flashing Error type Inverter/ Lamp failure Flashes slowly once Power failure Flashes slowly twice H: On L: Off H: On Center icon LED operation Main CPU to main CPU communication failure Flashes slowly 3 times L: Off H: On L: Off Others H: On Flashes slowly 4 times L: Off 2) Inverter/Lamp failure details (Flashes slowly once and flashes fast) Error type Center icon LED operation Lamp failure Flashes fast once H: On L: Off 3) Power failure details (Flashes slowly twice and flashes fast) Error type Center icon LED operation PS_ON AC_DET failure Flashes fast once SM_POW Main 13V failure Flashes fast twice D_POW Digital 3.3V failure Flashes fast 3 times PANEL_POW Panel 12V failure Flashes fast 5 times H: On L: Off H: On L: Off H: On L: Off H: On L: Off Note Pins are monitor microcomputer pins. Refer to "Inverter/Lamp failure details". Flashes slowly and fast by pressing the [MENU] key on the remote control (refer to 2 below). Refer to "Power failure details". Flashes slowly and fast by pressing the [MENU] key on the remote control (refer to 3 below). Refer to "Communication failure details". Flashes slowly and fast by pressing the [MENU] key on the remote control (refer to 4 below). Communication line failure or main CPU communication failure. → Check debug statements for the main CPU. Refer to "Other failure details". Flashes slowly and fast by pressing the [MENU] key on the remote control (refer to 5 below). Note Pins are monitor microcomputer pins unless otherwise specified. ERR_PNL(40pin): Hi failure. Confirmed after 8 consecutive detections at 64msec intervals (detected only when the backlight is on). Note that after five detection counts, the lamp cannot be activated except in the monitor process. Accumulated counts are cleared to 0 by the setting in the process A. Note Pins are monitor microcomputer pins unless otherwise specified. AC_DET(72pin) failure (L). If error is detected during start-up or operation, the power is turned on again by interrupt (instantaneous blackout processing). DET_13V(38pin) failure (L). Main 13V is not applied. If error is detected during start-up or operation, the power is turned on again by polling. DET_D3V3(36pin) failure (L). Digital 3.3V is not applied. If error is detected during start-up or operation, the power is turned on again by polling. DET_PNL12V(35pin) failure (L). Panel power is not applied. Detection is started after turning on the panel power and receiving command; the power is turned off by polling. 6 - 16
