    POWER Switch is Depressed (Schematic Diagram No. 10040925) 1. If the Model 40S6G18-L is operating in an otherwise normal fashion, the front panel LCD display or the wiring to it could be defective. 2. Check the LOCAL/REMOTE switch on the unit’s front panel; it must be set to the LOCAL position in order to operate the front panel POWER switch.
