Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.

Seven lights on this sort of TV generally signifies a connector loose on a board, or a dirty connector, or a board that is not seated right in its connector. It can also mean a defective logic board, though I would put that last, as a step toward repair, since the other problems can be addressed by a general cleaning and proper re-seating of connectors on all boards.

It may also mean a defective SU/SD board, but I am not sure of that. Some sources say so.

1. Reseated all cables/ribbons/connectors. Still getting 7 blinks when SD board is connected and 8 blinks when SD board is disconnected.2. You mentioned logic board, SU board and SD board. Which is defective?

I'm not sure which and I was not able to find any guidance. Perhaps another Expert will know what to advise you to do - and be right about it too, I should hope. I have Opted Out, with apologies at being able to take the case no further.

If you're not sure, why did you take my case? More in depth, precise and specific answers can be found by Google. This is a complete waste of money and would like to get a refund.
