Need help; troubleshoot no signal

[cp1966]

I have 4 receivers (3 Tivo, 1 standard) hooked up via a 3x4 multiswitch and a dual LNB plain dish (technically "round" I think).

Last night everything was fine. This morning I unhooked 1 of the Tivo recvrs (RCA 80 hour) because I needed to access the area above my stereo cabinet. I unhooked the power and all cables, did my work and hooked everything back up. Since it was a nice day, I also climbed up the ladder and pushed the wires back up into the soffit (attic) from the antanae because they were hanging down.

I went to watch Live TV via my TIVO and said I was unable to view Live TV, but I could still watch recorded programs. I checked the signal and it was at 90-91. However when I do a system check and said there was no signal, and then it said something similair to "119 A not found". I get the same problem on the other receivers.

With the exception of getting a new dish and LNB assembly and running the wires directly (bypass the multi switch) to the receiver, is there anything else I can check? Anyone have any thughts?

As usual, when I called DTV, they asked a few Qs, but short of setting up a $70 sevice call, they didnt have much to offer in terms of troubleshooting.

Also, the first time it ran thru diagnostics it said my account had been closed. But the tech at DTV said everything was fine and good.

Do you have this problem on all of your receivers, or only on the one tivo that you disconnected and reconnected?

If only on the one, I would double check connectors on the satellite coax going to it.

If on all, I would double check connectors on the feeds between the dish and the multiswitch.

All the recvers. I am sure when I find the problem, it will be something simple & easy. I have tried a few things already, but what really has me baffled is I get a 91 signal when I check signal strentgh, but when oi check my system set up there is no sgnal at all ( 0% ).

Very weird.....

Check all connections for corrosion etc etc.

Also, do you really only have a 3x4 switch? That means that your 3 Tivos are only using one tuner.

And, with only a dual output round dish you can't get the 119 sat. Make sure the receivers are setup to only use a round dish.

Check the signal strengths on all transponders.

The multiway switch is a 3x4, 3 in (2 from the round dish and 1 from an OTA antanae); so 4 outputs - 3 tivo and 1 standard receiver.

I did unhook the 2 cables running into the multiswitch and tried each one seperatley. 1 works great, the other does not. So, I will be climbing up tommororw to swap a new dual LNB and see if that will fix it. If not, it must be the cable somehow.....

Im getting close....
