I have a 47" Philips 47PFL7422D/37 that I'm having trouble with. It was on the other day, and all was well. A relay clicked, and the screen when off with no sound as well. The power light comes on, and a relay on the power supply board does click, but nothing. I have made a little video to show what the main board is doing at power up. I was wondering if anyone had a schematic or service manual for this TV, and if someone could help me troubleshoot it. I would appreciate any help.

Here a link to the video:

I'm thinking it's the main board, but I'm just not sure.

Thanks for any help.

Nicely done on the video.

It was kinda hard to tell what all lights were on on that LED lineup. is it the 1st, 2nd and 5th?
