Service Adjustments - Sharp LC-32GA8 Service Manual

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 with the remote controller, once unplug the AC power cord and plug it in
again. In this case, wait 10 seconds plugging.)
5- To remove "K" mode holding down the "VOL (–)" and "INPUT" keys on the set at once ("K" disappears).
Caution: Use due care in handling the information described here lest the users should
know how to enter the adjustment process mode. If the settings tampered with in
this mode, unrecoverable system damage may result.
