There is a post already opened:
I've just bought a new Samsung LN40A750. My first, move was to explore the menu. After one day, I decided to upgrade the firmware. I used ver.2003.2. Since the upgrade, I don't have access to the "content" menu. When I try to access it. the screen goes black.
My question is:
How do I go back to the manufacturer firmware?
Which firmware I should use to get this problem solved?
