Executing a function
The adjustment values are set to their optimum at the factory before shipping. If by any chance a value should become im-
proper or a readjustment is required due to part replacement, make an adjustment according to the following procedure.
1. Entering and exiting the adjustment process mode
1- Unplug the AC power cord of TV set to force power off.
2- While holding down the “VOL (–)” and “INPUT” keys on the set at once, plug in the AC power cord to turn on the
set. The letter K appears on the screen. (Factory mode)
3- Next, hold down the “VOL (—)” and “P ( V )” keys on the set at once. Multiple lines of orange characters appearing
on the screen indicate that the set is now in the adjustment process mode. If you fail to enter the adjustment process
mode (the display is the same as normal start up), retry the procedure.
4- To exit the adjustment process mode after the adjustment is done, unplug the AC power cord to force off the
power. (When the power is turned off by the remote controller, unplug also the AC power cord and wait for 10
seconds before plug it in again.)
5- To remove “K” mode, just repeat steps 1 and 2. This time the letter K disappears from screen.
2. Remote Controller Key Operation and Description of Display in Adjustment Process Mode
Input mode is switched automatically when relevant adjustment is started so far as the necessary input signal
available.
