Sanyo DP50749 - 50" Plasma TV User manual

DP50749-01
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.
P813 (SMPS)
P121 (LOGIC BD., LVDS Cable must be unplugged)
2) Short the pins together on Logic Bd. (drawing attached)
3) Apply AC power: If the panel and its PCBs are working, it will
energize, just as soon as pins 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.
(recommend that AC Filter be used for ease of connection, but
can be bypassed if needed)
Note 2:
Do not push the Pwr Key (the Main is not connected)
note 3:
no audio is available with panel self test
