Once you download the upgrade onto the flash drive and put into the TV, It should no longer be grayed out. Then choose via usb to upload the file. Hope that works for you
Thank you for your response. But when I go to Support on the tv the Software Update option is gray and not a clickable option. What now? (I watched Netflix just fine at 3 this morning!)
Kgilbert680 :
You need to go onto samsung.com and go to owners and support. Under that click downloads. Find your tv. Then you will need to download the update for your specific tv. Once it is downloaded to your PC, extract the files inside. Save onto a flash drive. Plug the flash drive into the tv. Then go to menu, support (I think) and there should be a software update feature. Click that and choose from USB. It should then update the tv and Netflix should work. The extraction of the files will only work if you have a PC. Samsung doesn't have a Mac version. Hope this helps. Took me hours to figure all this out!
