I have two 622's, but the TV 1 Remote on each of them has a different part number on the back. They both say 5.3 IR Remote, but the part number on one is 148785 and the part number on the TV 1 Remote of the second 622 is 143129. They both came with the 622 brand new box that I got in within the last 2 weeks from Dish. The problem is that with one of them, I can choose code 766 for my Sony amp, whereas with the other one (the 143129) it won't take it, neither directly, nor by scanning the codes. By scanning, it doesn't find any code that will operate the Sony amp. The 766 code is not listed in the table, but none of the Sony codes that are listed work. I have the same Sony amp in both locations. My guess is that one remote has more codes and thus includes the required 766 code. Has anyone run into this? Is there a solution to add that code? Should I contact tech support and attempt to get the remote swapped? Thanks!
