Normal operation (= product state)
When entering the service test mode without connecting any monitor
, connect TP/MUTEV to GND and TP/SVNMTE to 5 V
.
When resetting the service test mode, hold the power
-on state [STEST1/2 = H/H] and press the reset button,
and then turn off the power supply after having returned to the product operating state. (This is because the source selection contents set in STEST1/2 are stored last if the power supply is turned off in the service
test mode.)
