HD5: Reality Check Switch

Our Dish receiver's check switch problem, which was dismissed rather than being fixed when Dish technicians came out last week, has started happening again. It's not consistent, and this time it cleared up within about an hour, possibly because of a reboot, but even the CSR didn't think that was likely. So I have another appointment for Dish folk to come out next Tuesday, and that means I have to take another day off of work. The CSR wrote directions saying exactly what needed to be done and I don't intend to let them leave without actually replacing the switch this time. It only makes sense to avoid a few hours of travel and time here by replacing a component that's, I think, like $10.
