Multi-TV Drop outs - Channel dependent?

[rickster]

I'm running a 4 TV DirecTV setup (SD) with a DSL2 LNBF and SSM38 Sadoun 3x8 multiswitch. My unused outputs are terminated. I have an intermittent problem where sometimes all TVs will be fine, then some or all will go blank or breakup and the TV says "Searching for satellite" and not giving a picture.

The problem seems related to certain channel combinations. For example, say you are watching NFL channel on one TV successfully and have another TV on another channel. Then you switch channels on the second TV and you lose the NFL channel.

Another interesting thing is at some point you will have local stations, then at other times you won't even be given the option of selecting the local channels.

I've even tried a powered switch (thinking that was the problem) and that didn't help any. Any ideas?

From what you describe, it could be a one or a combination of issues:

Since you are using one LNBF, I assume your dish is perfectly aligned to one satellite.

Start trouble shooting by following the steps below
1- Remove terminators and see if that solves it
2- Check all connectors and cables to make sure you have a good connection and no shorts in the lines.
3- Disconnect the switch, and run two cables straight from the LNBF to two receivers. Check the channels again and see if you notice the same problem or not. If the problem is resolved, then it could be the Switch is BAD.
4- Change LNBF with another LNBF and see if you notice the same problem or not. If the problem is resolved, then it could be the LNBF is BAD.
5- Change Switch with another Switch and see if you notice the same problem or not. If the problem is resolved, then it could be the Switch is BAD.
6- last resort, change Switch & LNBF and see if you notice the same problem or not.
