SHARP LC-42DH77E/RU/S/V - LC-46DH77E/RU/S/V - LED BLINKING CODES - Error Codes _ Universal Remote Control Set-up Codes

LED BLINKING CODES & FAULTY CIRCUIT SECTIONS TO BE CHECKED

LED flashing method

• Synchronize the phases of the power LED and OPC LED.
• If the LEDs have different number of flashings, adjust the flashing cycle to that where the LED flashes more times.

FLASHING PATTERN

ERROR ERR STBY Table

{CLICK ON TABLES TO ZOOM IN}

Lamp failure Flashes once => ERR_PNL(40pin): Abnormal L. 

• Confirmed after 5 consecutive detections at 1 second intervals (detected only when the backlight is on).
• Note that after five detection counts, the lamp cannot be activated except in the monitoring process. (For the first time, only the inverter is reset, and error OFF is not activated.)
• Accumulated counts are cleared to 0 when the setting in the adjustment process is made, when AC_ON is performed with [CH_DOWN] and [VOL_UP] on the unit down or after continuous illumination for 3 minutes.

PS_ON AC_DET failure Flashes once => AC_DET(72pin: Abnormal (L).  If error is detected during start-up or operation, the power is turned on again by interrupt handling (instantaneous blackout processing)

D_POW Main 12V failure Flashes twice => DET_12V(34pin): Abnormal (L). Main 12V is not applied.  If error is detected during start-up or operation, the power is turned on again by polling.

D_POW Digital 3.3V Failure Flashes 3 times => DET_D3V3(35pin): abnormal (L). Digital 3.3V is not applied. If error is detected during start-up or operation, polling turns on the power again.

Communication failure details (Power green LED flashes once and OPC (preset) LED flashes)

Initial communication reception failure Flashes once => Initial communication from the main CPU is not received. (Request for the monitor model No. is not received.) à Communication line failure or main CPU start-up failure.

Start-up confirmation reception failure Flashes twice => Start-up reason confirmation from the main CPU cannot be received. (Startup communication until start-up reason notification command is not received.)  à Main CPU start-up failure or monitor microprocessor reception failure.

Regular communication failure Flashes 3 times => Regular communication that is performed at 1 second intervals in the normal operation is interrupted. àMain CPU operation failure or monitor microprocessor reception failure.

Other communication failure Flashes 5 times => When a request (PM_REQ=H) is sent from the main microprocessor, the request command is not output from the main CPU, etc. à Main CPU operation failure or monitor microprocessor reception failure.

Monitor temperature failure Flashes once => If the panel temperature is 60°C or more for 15 seconds 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 25 seconds or more in a row, error standby is activated. --> Thermistor

Main failure Flashes 3 times => Main microprocessor detection error (CPU temperature error, etc.)
