Help!. No signal on 3 HD channels

[Senz]

Hello.

Up until last night, i have received all the mpeg4 channels. Then all of sudden. versusgolf HD stopped working. So i fiddled around and checked everything out, and BravoHD is missing as well.

I ran a sat signal test, and everything comes in on 103B except transponder 12.. its at ZERO.

after searching the forums, i found a transponder map, and Those 2 channels shared transponder 12.

What can cause this to happen? i was getting the golf channel in HD and bravo just fine, until late last night. Now all tv's in the house return transponder 12 as Zero. and searching for signal.

What should i try?

Thanks

You might have a bad multiswitch. I had the exact problem. Missing TbsHD and FXHD and a couple of others. A tech came out Wednesday and did some testing and was that my multiswitch was faulty.
