As Bruce Esquibel so eloquently stated:

Dunno about the receiver (I have an older dct-100) but it's possible the
"B" LNB just crapped out being you are getting a zero reading, or the
dish went out of alignment.

I know they moved things around but was under the impression some of the
HD stuff was mostly fed off the C though. They have some test channels
around 490-496 I think that is a barker channel for each satellite and
polarity.

One thought, on the dct-100, there is a config menu for dish type, not
sure if it was carried over but you need to tell the receiver the type
of antenna you have, single, dual or triple. If it's not on triple, it
doesn't send the correct tone signals to the multiswitch, so again, C or
B could be missing because of that.

The receiver going bad is always possible but not likely in this case.

Can't say a simple troubleshooting process but in order:

1) improper configuration on the receiver
2) dish alignment, especially "tilt"
3) bad lnb
4) bad jumper on lnb to multiswitch assembly if it's the older type
5) bad multiswitch

Thanks for the info.

I think I've narrowed it down to the LNB(multiswitch). It just ticks me off
that it went bad in 6 months. And DirectTV want to charge me $70 to replace
it(service call) since it only carries a 3 month warranty and one year
parts.

Thanks,
