Black screen to blue
I have a D39h-C0. It worked fine one night, the next night I turned it on, there was no sound/display and a black screen. I replaced the power board, now I get nothing but a blue screen.
ANSWERS:
@dmac1221 if it is a completely blue screen it is most likely that you are not getting any video source to the display. You did make sure that you have the proper power supply installed and you checked all your connections of course. Remove the back of your TV and post an image of the boards with your question. That way we can see what you see. Use this guide Adding images to an existing question for that. Looks like your power board also includes the main board. My first suspicion would be a bad main board circuit on your board.
