IDENTIFYING THE TYPE OF DISPLAY
To date, there have been four different manufacturers of
displays that the Quantum™ Control Panel has used. It is
important to be able to determine the type of display that
you are installing, so that it can be properly matched with
the version of Quantum™ controller already in place. The
reason for this is that each of the manufacturers has their
own requirements for both logic voltage, and for backlight
voltage for their particular display. Fortunately, the
Samsung, NEC, and Sharp displays all share the same
voltage characteristics, only the LG Philips display varies
from this voltage requirement.
A sticker should be affixed to the top center of the
mounting plate. This sticker will give the part number of
the assembly, the display (and type of display), and the
inverter. If this sticker is not present, or to confirm the
sticker information, measure the distance from one end of
the white display mounting plate to the other, as shown
below. If the distance is approximately 12-3/4", the display
that is mounted to the plate is either a Sharp, NEC or
Samsung. If the distance is approximately 11-3/4", the
display is an LG Philips, as shown below.
Once the type of display is known, you will want to use the
chart at the bottom of this page to determine the proper
parts compatibility.
You will also need to refer to the jumper settings for the
appropriate Quantum™ controller that is installed.
Display Replacement
