I have a friend who is having problems with his DTV system. Tree d-15 Rcv's....a 6X8 switch....two dishes. The locals are on 72.5.

His system is intermittently dropping the locals on 72.5. I re-pointed his local dish and signal levels went from 55 to 92 on the receiver signal meter. I replaced the LNB....checked all the connectors and replaced the 6X8 switch. It is happening on all receivers. No change in the intermittent dropping of channels. The cable run is about 150 feet...but this did not start happening until this winter. The switch is at the dish where the run to the switch is short.

This is driving me crazy.....and makes me very upset that I can't fix it YET!!

Any help would be appreciated.

Changed the LNB & switch, short cable run to switch........Hmm......thats a tough one.

I would check the signal levels again. Make sure they are holding steady and not fluctuating. A bad AC outlet can cause signal levels to fluctuate, as you probably already know. When I check, or in your case replace, all the usual suspects, I start looking at the AC plugs and even the ground as the possible culprit. Good Luck!

Sounds like the only common factors left are the cables from the 72.5 dish to the switch and... if it's a powered switch, the power cable/transformer, although I wouldn't suspect them. What about a recent software download that all receivers took and now have the same problem?

I have had a bad house ground cause the switch not to work once multiple receivers were hooked up.

We'd had the same problem, but there was only 1 receiver on the account. The problem seems to be cured since following the last suggestion. Read about it here:
