What can kill two 110/119 at once on two receivers?

[liamklub]

I have two receivers 3900 and ??, and two old Dish 500 antennas, one pointing
at 110/119 the other at 61.5.
Yesterday, reception on satellites 110&119 and both receivers ended upruptly.
Other than an obstruction (bad weather doesn't typically last this long (over 24h) and trees don't grow overnight to completely block my signal, what else
would make a single point of failure in the Dish 500 quad LNBF?

Note: I have power-cycled my 3900 and continue to receive the channels on 61.5W.

Please give more info. I assume u are useing a sw64 switch with ur two receivers. More info will help diagnose your prob.

Sounds like te switch is locked up. Try removing ALL power from the switches and receivers then power them back up and run check switches. this could correct the problem. By removing all power i mean unplug

You mention a Quad which drives the signal from 110 & 119 and 61.5 that is still working. I would have to guess the Quad has failed.

the lnb could have failed. I had one side of my DIsh500 do that.

Or one side of the switch. Before getting a new LNBF, barrel the line together from the rcvr straight to the dish 500, run a switch check. If that works, then you switch is bad.

If it's happening to both rcvrs, then it could be the LNBF, if not, the receiver or the line itself. Swap rcvrs to see if the problem goes into the other room, if so, then it's the rcvr, if not, the line or LNBF.

One note - when you power down, power EVERYTHING down AT THE SAME TIME - and don't forget the SW64 power inserter. Leave them off for at least a full minute.

why does everyone think he is using a SW64?
The OP never mentioned it. Maybe he is running a Legacy Twin/Legacy Dual combo connected with 2 sw21's

He said he has a Quad so that eliminates the Twin and SW-21s. Logic says 4 feeds from Quad into SW-64 and 2 from 61.5.
