NORMAL STANDBY CAUSE
Location: Page (1) of the adjustment process mode: NORMAL STANDBY CAUSE
Outline: When TV set is powered off due to normal use or product specification, the last cause will be recorded.
The code, character string and description for the standby cause are below.
If you power off by remote, the cause will not be recorded.
If you power off by remote, the cause will not be recorded.
ERROR STANDBY CAUSE
Location: Page (1) of the adjustment process mode: NORMAL STANDBY CAUSE
Outline: When TV set is powered off due to any anomaly detection, the past 5 causes will be recorded.
You can confirm the time those causes occurred and character string in the adjustment process mode menu.
The time is accumulated total after TV set is powered on, and the value corresponds to “Center Acutime” on the page(2) of the adjustment process mode menu.
The code, character string and description for the standby cause are below.
If no error has occurred, the code is 0 and the character string is “NO RECORD”.
The time is accumulated total after TV set is powered on, and the value corresponds to “Center Acutime” on the page(2) of the adjustment process mode menu.
