Samsung ps43d490 cracked screen

[maxwell2121]

I have a Samsung ps43d490a with a cracked screen. As it is probably useless to repair I thought it would be good to learn on as I used to repair CTV's 15 years ago. The y main board has a S/C RJP63K2 FET. As I have no circuit it is guess work, and I am assuming it supplies HT for screen. Is it possible to repair boards and fire up tv WITHOUT screen connected? If anyone has circuit it would be useful.

These Tv's womt turn on with out the Pdp connected, the controller detects that the boards are not sustaining the panel and shuts down. Also a cracked Pdp can kill the Ymain as the electrodes in the panel short out which can kill the Ymain. So either the Ymain has died or its going into protect mode because of the cracked panel.
