ERR_PNL (pin 40): 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 counts are cleared to 0 when the corresponding
setting in the 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.

Refer to "Communication failure details".
Communication line failure or main CPU communication fail-
ure. → Check debug statements for the main CPU.
