Unlock loc 917Sw - LG Flatron L1750S 17" LCD Monitor

From a google search the following is copied:

LOC is a control panel lock not a door lock, see below.

The Control Lock shuts down the control panel pads to prevent
unintended use of the ovens.
When the control is locked, only the CLOCK, TIMER SET and
TIMER OFF pads will function.
The Control Lock is preset unlocked, but can be locked.
To Lock/Unlock Control: Before locking, make sure the ovens,
Timer and Timed Cooking are off. Press and hold START/ENTER
until a single tone sounds and "Loc," a picture of a lock and
"START?" will appear on the oven display, about 5 seconds.
Repeat to unlock and remove "Loc" from display.

If the above does not work have you tried removing power from the uit for a few minutes to see if it will reset.

The control is locked to avoid having someone accidentally start or stop the dryer. Press and hold the Options and Select buttons for 10 seconds or until the "LOC" on the display is cleared. Locking the control is done the same way it is unlocked.

Press Options and Select at the same time and hold for 10 seconds or until "LOC" is no longer displayed to unlock the controls. Press and hold the same buttons for 10 seconds until "LOC" is displayed alternately with the estimated cycle time to lock the controls. Unplug the machine for at least half an hour, if pressing the buttons does unlock the controls, to forcibly reset the machine control and eliminate the possibility of an electronic glitch.

HI. The term"LOC" will be an indication of the "Child Locking" feature that has been activated either by mistake or intentionally. This is a safety feature to prevent unwanted starts when children are present.

To unlock the controls,press "Options and Select" at the same time and hold for 10 seconds until ”LOC” is no longer displayed.

• NOTE_ If the release procedure doesn't unlock the unit and the letters LOC continue to appear, this will be a strong indication of a severe fault within the main control board. try to power cycle the unit if this is the case. if the power cycling doesn't produce good results, replace the main control board assembly.

This particular model does not come with any audio connections. It only has a standard RGB D-sub (VGA) connection.
