7-2-1. Check when turning OFF the lamp error detection
If the power has been turned off 5 times because of lamp error, hold down the unit’s "INPUT" and "Volume
(–)" key simultaneously and turn on the unit’s power switch. The TV set gets back on power in the "K"
mode.
In this state, press the unit’s "Volume (–)" and "P (

)" key simultaneously. The Adjustment Process mode
shows up.
This enables the operation check to detect errors in the lamp or lamp circuit.
Check whether "ERROR NO RESET" of the adjustment process is 1 or more. If it is 1 or more, it indicates
the lamp error detection was executed.

RESET" of the adjustment process and set the number to 0 using the "LEFT" or "RIGHT" cursor key.
