Can't Post

Hi, I have a PPM50H3 plasma screen which is stuck in standby. I have checked the power board and can see no damaga at all. All the caps and fuses seem fine, so i have found a schematic and tried to trace the problem. The main power relay does not click on at all. The power LED blinks red 9 times then goes out.
Can anyone suggest whati should check next? the schematic can be found here

Thanks in advance
