pdp 4210 LG black screen.

[sbelli]

Hello ,
Sorry , I'm a new member and I'm french .I've a plasma FIRST LINE PDP4210 but in fact this is a LG screen and board .When I switch on the plasma , the led is green , and I have a black screen .It's strange the big IC on the ZSUS is hot and the big IC on the YSUS is cold . I control my  2 fuses on YSUS board , it's ok and I've on VS point 132 VOLTS .
What thinking about this problem ?
My YSUS card is a 6871QYH029A.
Thanks .
Stéphane .
