Hi, I'm Nathan.
Sorry to hear that you're having trouble, but I'll do my best to help you. Please give me a few moments to review and reply.

Are you getting sound?
Were the symptoms exactly the same before and after the main board?
If you hold a flashlight to the screen, can you make out any images there?

I love this site! $9 instead of a repairman or new/used frig can't be beaten. This older woman will worry less now that she knows about this site. Bless you all.
