Error Code Operational Check

If the TV shuts down for some unknown reason the
Error Code Operational Check usually indicates the
cause.
When the TV shuts down the Operational Check can
be performed. DO NOT shut the TV Off. Press and
Hold the DEVICE and MENU buttons, for 5 seconds.
The Power LED will start flashing a two digit Error Code.
To determine the error code: count the number of times
the Power LED flashes.
• First the value of the MSD (10s digit) is flashed.
• After a short pause, the LSD (1s digit) value is
flashed.
• The code is repeated 5 times.
Table 5-3 lists the possible Error Codes.
If installing a new Lamp Cartridge does not cure the
problem, the problem could be due to Lamp Ballast or
the Chassis.
Refer to page 2-7 in Chapter 2 on how to access the
Lamp Ballast.
