DP50747-00
Panel: Self Test
Panel is capable of generating internal patterns without the Main
Signal Board attached. (rotating: white / red / green / blue / and
various other patterns)
This test eliminates Main Signal Board from circuit and confirms if
panel itself is operating properly.

1) Unplug these connectors from SMPS and Logic Board.
CN8003 (SMPS)
CN8004 (SMPS)
CN2001 (LOGIC BD.)

2) Short pins 1-4 together on Logic Bd. at CN2007.
(a small screw works good to short all together)

3) Shorting pins Gnd & PS_ON at CN8003, (3rd & 4th pin from
bottom of connector) will energize the panel, after AC power has
been applied in step #4 below.
(If AC power is applied and panel is working, it will energize
with rotating patterns just as soon as pins Gnd & PS_ON are
shorted)

4) AC power must be applied to panel. Power cord can still be
attached to AC Filter, or power can be applied directly to
CN8001 on SMPS.
(recommend that AC Filter still be used for ease of connection,
but can be bypassed if needed)

5) Please remember to remove short at CN2007, when finished.
