DP50747-02 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. CN800 (SMPS) CN802 (SMPS) CN803 (SMPS) P1 (LOGIC BD., LVDS Cable must be unplugged) 2) Short pins 1-2 together on Logic Bd. at P7. 3) Apply AC power: If the panel and its PCBs are working, it will energize. Just as soon as pins 1 & 2 (P7) are shorted, the panel will have several rotating patterns on the screen. note 1 : Power cord can still be attached to AC Filter, or power can be applied directly to SMPS.
