Installation problem - help wanted!

Vu+ Newbie
Hello,
I've been having trouble with my VU + Duo...
My set is as follows, 2 LNB with dual outputs, they are connected to 2x switches (each LNB has connections to the LNB 1 & 2 of the switches, this is connected correctly because it worked initially).
I have excellent picture from one satellite (Canal Digital) but nada image on the other (Viasat)... Initially both satellites had coverage. I use SatFinder built into the box, I have SNR 99% on Tuner B constant. However Tuner A is about 70% but often disappears entirely and goes down to 0%. When it is reasonable (around 75-80%), then the AGC is 99% and BER is 0. When tuner A is on SNR 0% the AGC goes between 0 to 80% extremely fast. Even when it is located at 75-80%, I have no channels on Viasat.

What I do not quite understand is the meaning of Tuner in the box ... Does A & B means the LNB (satellite), or does it means each tuner in the box (which has a signal from both the LNB 1 & 2)

Now I see that this thread was messy, do you see my problem?
Do you think I should just do a new channel scan?

/ Sten

Ps. sorry for my bad english grammar

Click to expand...

2 Tuners,,,means U can connect more than 1 dish to connect to tuners A & B!
Never mined the numbers of LNB (using dysQ switch, I have one with 8 slots,,1 to 8 LNB)!

Regrading the SNR instability,,,am having the same with my Duo.. usually the LNB brand/type has a problem especially with HD channels!
Soon am going to change the LNB with other type,,,and see if the problem will be solved!
 
What Diseqc settings do you use Sten?
I personally have had more success with the A, B, C, D,.....etc settings than with 1, 2, 3, 4,.......etc
