Help with satalite connection
Discussion
So.i cam back from holiday to find my Humax box complaining of weak or no sat signal.
I bought one of those cheap satalite finders things to see what the problem is.
I just connected it all up and I think there is nothing wrong? I connected one end direct underneath the LNB block (to one output), the other to the Humax and then switched on. I get a red light on 0hz and 13V and if I adjust the sensitivity it buzzes. If I just reflect the dish slightly the signal drops away. I need roughly equal deflection in any direction to make the signal drop so I believe the dish is still aligned.
I have other LEDs though for 22khz and 18v...these do not light up. However am I correct in thinking these are actually controlled by the reviewer box? I.e. it sends a higher voltage or higher frequency to read different polarization?
If I have a signal and apparently have a good electrical connection between reciever and dish why am I getting bupkis?

Are all channels showing low signal, or just some? You are correct the receiver switches between 13v and 18v to change polarisation of the LNB, this can fail at either end so only one polarity can be received.
Also check all connections are good and no water is getting into them.
Sometimes a simple hard power cycle can fix issues. Switch the box off at the mains and on again.

Okay, figured it out
After checking signals on all 4 cables from the LNB and even making sure it was pointing at the right satellite, I discovered the problem was one of interpretation.
When the Humax box says there is no signal, what it meant was there is signal, but its just lost its programming for the channels. The signal strength and quality bars were at zero. But I scanned for the channels again and whilst it kept displaying the no-signal warning, it found and reprogrammed all the channels and was right as rain again.
I think, having been switched off completely for 4 weeks, it probably lost its settings.
