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 & Logic Board. CN8004 (SMPS) CN8003 (SMPS) CN2013 (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 top 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 by passed if needed)

5) Please remember to remove short at CN2007, when

finished. note: no audio is available with panel self test
