Sorry to bump an old post, but this is exactly the problem I am having with one of my 3100's.
I've lost all transponders 13 and over. Signal strength is 0. I've tested the receiver on several dishes, all using proper cabling, with other receivers getting all appropriate channels.
Here's the twist -
Upon the first call to BEV, the tech support in India outright said it was a hardware problem and a new reciever needed to be purchased/rented. Although this was the newest unit I have (2 2700's working fine), I accepted, and went out and purchased a new HD unit. Upon calling the sales department at BEV (not tech support) the CSR noticed that one of my 3100's was "disabled." She quickly activated it, and what would you know, all channels/transponders on the 3100 was working just FINE!
What a relief - for about 3 hours. After that time, the issue (deactivation) reappeared, and at one point, one of the 2700 units was doing the SAME thing. Additional calls to BEV CSRs (tech) after describing the problem without any sort of diagnostic was that the hardware needed to be replaced.
My problem with this situation is, why was the BEV CSR (sales) able to 'reactivate' the unit for a duration of 3 hours, and the 'tech' departments only fix is to replace the unit.
I've also heard that BEV randomly deactivates units for the customer to call in to try to pitch them a new unit, etc, and that they don't want this old hardware out there.
Calls to the CSR's are hopless, and after the conversation with the sales CSR and reactivation, I'm certain that the unit is functioning properly, and that BEV is messing with my unit.
Any comments would be appreciated.
