This is a system setup for my own personal system. Some of them are discrete, some are not. There was a few pieces that had no discretes, so I improvised. The Onkyo receiver is part of a HTIB and with the power, only the off command is discrete. I could not find any discrete on command for this model. The TV has no discrete power or inputs so that was the toughest. I found a way to trick the system and work around the lack of discrete inputs. The only reason it worked is becuase this TV has seperate input commands for composite and componet and as long as you know the order, it's easy to trick and works flawlessly. I had to use an all on command because the lack of discrete on this TV.
