) Power-On control signal for Power Supply Unit
(1) AC switch : ON
Æ
PSU outputs STBY+5V.
(2) PoWER_1 (CN63 [6]) : High
Æ
PSU o5.6V.
(3) PoWER_2 (CN63 [7]) : High
Æ
PSU o10V and +12V.
(4) Vcego (CN68 [7]) : High
Æ
PSU outputs Vcc+5.1V for PDP Panel.
(5) Vsago (CN68 [8]) : High
Æ
PSU outputs Va and Vs for PDP Panel.
If any control signal does not rise, PSU cannot output the voltage.
・
PoWER_1/2 : not rise ----- Main-Digital PWB trouble
・
Vcego/Vsago : not rise ----- PDP Panel Module (Logic PWB) trouble
However, Vcego rises when PNLRST (EC01 [43] at Main-Digital board) is High, and
Vsago rises when PNLoN (EC01 [42] at Main-Digital board) is also High.
