I recently updated the firmware on my Samsung LCD model LN46A550 to 1006.1 from the factory firmware. Unfortunately, I made a mistake and upgraded using the 1006.1 package before the 1005.1 package (they are listed side by side on the website).
I didn't realize this at first. After my TV reset, I tried auto-programing the tuner and it couldn't find any channels. After getting really worried, I noticed that I had the 1006.1 version installed. Wondering if this was the problem I installed 1005.1, thinking it might update the firmware for the main processor, but that didn't fix things. I then installed 1006.1 on top of that and that didn't fix things either.
Could the firmware upgrades have affected the tuner? Where there any changes to the tuner between firmwares? Any other idea what might have happened?
Is there any way to roll this back? This is extremely frustrating. I know I am still getting a signal from my cable since I plugged it into another TV.
