Hitachi 42PMA400A Plasma

[Typhoontimmy]

Hi there
I have a Hitachi 42PMA400A Plasma and it has a power up problem. when you turn it on the realy clicks and the light on the front goes from red to green and it displays the picture for a split second and it goes away and about 5 seconds later the light goes back to red and the relay clicks.

People have told me "just replce two Caps in the YSUS board and this will fix the problem but i have replaced a total of 12 Caps in the board already and it's still doing the same thing.

plz help
