Summary of Self-Diagnosis Function
This device includes a self-diagnosis function.
In case of abnormalities, the TIMER/STAND BY indicator automatically blinks.  It is possible to predict the abnormality location
by the number of blinks.  The Instruction Manual describes blinking of the TIMER/STAND BY indicator.
If the symptom is not reproduced sometimes in case of a malfunction, there is recording of whether a malfunction was generated
or not.  Operate the remote command to confirm the matter on the screen and to predict the location of the abnormality.
2.
Diagnosis Items and Prediction of Malfunction Location
When a malfunction occurs the TIMER/STAND BY indicator only blinks for one of the following diagnosis items.  In case of
two or more malfunctions, the item which first occurred blinks.  If the malfunctions occurred simultaneously, the item with the
lower blink count blinks first.
The screen display displays the results regarding all the diagnosis items listed below.  The display “ 0 ” means that no malfunc-
tions occurred.
Lamp OFF : 
3.0 seconds
Lamp ON : 0.3 seconds
Lamp OFF : 0.3 seconds
Release of TIMER/STAND BY indicator blinking.
The TIMER/STAND BY indicator blinking display is released by turning OFF the power switch 
on the TV main unit or removing the plug from the power.
