Thanks for your support of Samsung products!
Here's a handy shortcut to help you out.

Hope this helps!
I have had my LN40A650 for 4 days now. I love it. I have been reading this forum for a few days now and also registered the LCD on samsung website. According to samsung.com my set was manufactured on 12/31/2008. I am assuming it has the latest firmware but I would like to check. Is there a way to see the firmware version or do I have to attempt to upgrade it?
