Lighted LCD microwave display is intermittent

Our Sharp built in microwave, model no. R-420DK, hasn't had a LCD
display that was easily visible (especially at night) since we bought
the house 3 months ago. The light for the display came on yesterday
and today while we were using the touch pad. The light stayed on for 5
or 6 seconds each time and went out when we opened the door or punched
another button on the touch pad.
I'd like to try to troubleshoot and repair the LCD light circuit, and
need info on safely accessing the lighting circuit.
