I have a Slimline5, HR21-700, both tuners have bbc connected. Strong signal on all satellites, 101, 110, 119, 99, but 103 is dead. Had tech at the house yesterday, and after 2 hours of troubleshooting, nothing was solved. Ruled out the possibilities of a bad bbc(replaced w/ new), bad cable(ran new solid cable from dish to receiver), and reset receiver multiple times. Tech is receiving signal from all satellites on his Birddog at the dish, but the receiver can't seem to see 103. Is it possible the tech doesn't know how to read his meter?, or is it possible that something is wrong inside the receiver, not allowing it to see 103. I live in DFW, and most of my HD content is located on Sat 103(c) TP 21. Any info would be greatly appreciated. -Thanks
