Question about Mitsubishi Televison & Video
I have the same tv and same issue. I found chain of notes indicating that you can clear the lock by pressing 9-QV (two buttons) on the original remote at the same time. This works... however if you change the input again the EXT1 and EXT2 inputs will be locked again. It would be really nice if you can remove the lock feature completely.
