Anyone got a schematic for the 9000i? I think I need to replace the IR diode in the receiver. Either I'll do that or see if the UHF remote is still available. Or maybe I'll look into getting a 4K STB even though I don't have a 4K TV yet. I'm not sure if I want to spend the bucks but if I can get a decent, reliable receiver it'll cost less than a pizza dish sub (over time).
