Sagem ISD91 HD with 60cm dish for French TNTSat.
Dell 8100 with Windows 2000.

- London, east
Hi Everybody,
This is my first post, and I will confess to being new to both this forum and to satellite TV. I was in France recently and I purchased a Sagem ISD91 HD box with a 60cm dish and a single universal Lenson LS101 LNB (ref 800657), which I brought back to London in order to watch French TNTSat TV. I have put up the dish and connected everything together, but I don't appear to get any signal at all.
I have read through all of the "stickies", and also Puntodepartida's excellent instructions. This is what I have checked so far;
1. Alignment of dish (East London) - elevation 28.3, azimuth 156.1 (true) or 157.9 (magnetic) and LNB skew -7.1 degrees.
2. Line of sight from dish - clear sky all the way to Astra 19E.
3. TNT Access Card - installed the correct way up.
4. Cable - with a test meter, I know I have connectivity between the box and the F connector at the LNB, and no shorting between the outer braiding and inner core.
5. Power at the LNB - During scanning for channels, I have measured both 13v and 18v at different times at the external F connector (I can't accurately check the current, as the scale on my meter goes from 1 to 10 amps, but it is clearly under 1 amp).
These are the questions I have at the moment;
A. From everything I have read, I believe that I have the dish correctly aligned, but how accurate do I need to be? I'm sure that I have the elevation right, but how close should the azimuth be - nearest degree, minute or seond? How critical is the LNB skew? If this was wrong, would I get a feint signal, or nothing at all?
B. During alignment, I can see the TV screen. The strength of signal display (from the box) shows just a small red bar (i.e. no signal). Are these displays usually "live" or do they simply show a record of the signal at the instance the button on the remote control is pressed? What extra benefit would I get from a strength of signal meter?
C. I know that TNTSat HD TV is not switched on until 15th February 2009. Surely I should get the standard signal? Presumably, I register my TNTSat access card once I get connected?
D. The box seems to be functioning correctly, but how can I be sure that the LNB is not faulty? The LNB box says incoming frequency 10.7 to 12.75GHz, which matches the specification requirements given in the Sagem manual. However the LNB itself is labelled 12.25 to 12.75GHz, but this is not what is given on the Lenson website. What is the significance of these discrepancies?
E. What else can I check?
Many thanks in anticipation for any help or suggestions that anybody can provide.
Regards,
Philip
