1) Power LED (The power LED (Green) which lights during TV reception flashes.)
2) Power failure details (Power LED flashes twice and OPC LED flashes)
LED flashing timing chart for error notification.
Error type Power green LED operation (1 cycle) Pins are microprocessor (IC2002) pins.
Lamp failure
Flashes once: Fast
ERR_PNL (pin 43): L failure. Confirmed after 10 consecutive
matches at 500 ms intervals (detected only when the back-
light is on).
Note that after five match counts, the lamp cannot be acti-
vated except in the monitoring process. (For the first time,
only the inverter is reset, and error OFF is not activated).
Accumulated “LAMP ERROR” counts are cleared to 0 when
the corresponding setting in the page 1 of process A is made
or when the power is turned on with [CH_DOWN] and
[VOL_UP] on the unit down or after continuous illumination for
3 minutes.
Power failure
Flashes twice
Refer to “Power failure details”.
Communication failure with main CPU
Flashes 3 times
Refer to “Communication failure details”.
Communication line failure or main CPU communication fail-
ure. → Check debug statements for the main CPU.
Communication line with main CPU: TXD (pin 28), RXD (pin
29)
Vsync
Trident failure
Flashes 4 times
VSYNC (pin 46) failure (uninput). Trident_IC operation failure.
Detected during operation (interruption).
Monitor temperature failure
Flashes 5 times
If the panel temperature is 60°C or more for 15 seconds or
more in a row, CAUTION appears on the OSD “TEMPERA-
TURE” of AVC (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.
[Method of evasion] MONITOR MAX TEMP on page 23 of
process A: Temperature protection threshold is changed
small.
Program data broken
Flashes 8 times
Internal Flash ROM data is not correct.
[Restore] Write Monitor Micon software.
Error type Notification LED operation (1 cycle) Pins are microprocessor pins unless otherwise specified.
PS_ON
DET_10V failure
Flashes once
DET_10V (pin 57). UR10V or A9V is not applied.
If error is detected during operation, error standby is activated
by polling.
D_POW
DET_D3V3 failure
Flashes twice
DET_D3V3 (pin 59) failure (L). D3.3V is not applied.
If error is detected during operation, error standby is activated
by polling.
D_POW
DET_6V failure
Flashes 3 times
DET_6V (pin 56) failure (L). D5V or A5V is not applied.
If error is detected during operation, error standby is activated
by polling.
