3 . Error Code Operational Check
Note: The TV must be in “Shut Down” and not have been switched Off, to p\
erform the Error Code Opera-
tional Check.  When the TV is switched Off, the code automatically resets to “12” No Error.
Pressing the front panel “INPUT” and “MENU” buttons at the s\
ame time, and holding for 5 seconds,
activates the Error Code Mode.  The “TIMER LED” flashes denoting a\
 two digit Error Code, or indicating no
problem has occurred since the last Initialization. Note:   The front panel buttons must be used, NOT those on the Remote Control.
•The number of flashes indicates the value of the MSD (tens digit) of t\
he Error Code.
•The flashing then pauses for approximately 1/2 second.
•The LED then flashes indicating the value of the LSD (ones digit) of t\
he Error Code.
•The Error Code is repeated a total of 5 times.
Example:  If the Error Code is “23”, the LED will flash two times,\
 pause, and then flash three  times.
LED Indicator Diagnostics
The front panel LEDs provide  an indication of the set’s operation, a\
nd the possible cause of a malfunction.  There are three
front panel LEDs, “Power”, “Status” and “Lamp”.  The LED display shows the current status or indicates a possible
malfunction.
