Missing Channels - no Satellite Signal is being received

    Hi
    I'm having an issue receiving some channels on 2 different boxes. I have 2 Sky+ box - 1 with no sub as a free to air and an Irish sub on another box. They are running on a quad LNB.

    On the Irish box I cannot get RTE1, TV3E, Watch, Dave, Gold and others. I do have RTE2 fine.

    On the free box I have all BBCs, ITVs - but am missing Tiny Pop for example. It comes and goes sporadically. I had suspected the LNB, but changed it for a spare quad I had, with no change in reception. Signal on both boxes is around 75% with quality around 50%.

    Any suggestions?

    Thanks in advance

    Apart from 3e, all the Irish channels are on the same transponder, so if you get one, you should get them all.

    I would think the quality should be better than that. Usual suspects: misaligned dish, dodgy cables or connections.

    I seem to get same issue with Sony TV and its +1 version. Other channels fine and Sony TV breaking up and showing no signal received message.

    Vintage TV (music) was always missing, pausing, freezing on me.

    Installed new cable and put up a new dish I got with HD box 2 years ago. Good improvement considering I used a €10 dish alignment meter.

    Happy with all my work. Got cable and meter from tvtrade (no affiliation to company).

    My Dad is having a similar problem, he has lost the following channels, 105 3e, 113 Universal, 114 SyFy, 144 Dmax, 146 CBS Reality, 147 CBS Reality +1, 150 Universal +1, and some others.
    I have checked cables and connections at both ends, they appear to be fine. Dish has not moved.
    Checking signal strength I found no signal on input 2, swapped cables around and got no signal on input 1.
    Performed forced software download and got signal on both inputs, however as soon as any of the above channels are selected, signal disappears from 1 input?
    Its a quad LNB with only two outputs in use, so tried swapping outputs around to no avail. I suspect the LNB may be faulty.
    I hope so, I cant see Sky replacing his box for him

    Does anyone know whats going on?

    Have a look at http://en.kingofsat.net/pos-28.2E.php and see if there's any pattern to the missing channels such as same satellite, same frequency, same polarisation etc.

    A very small movement of the dish could lose the signal from the weaker Eutelsat satellite, those channels you list appear to be on that particular satellite. It could also be an LNB problem.

    Thanks for that :)
    I thought that all the channels on Sky came from the Astra satellites, I didn't realise they also used Eutelsat :confused:

    Does this mean that when I managed to restore signal on both inputs that both signals were from Astra, and I lost signal when trying to access signals on Eutelsat?

    I have a basic signal strength meter, will it be sensitive enough to allow me to realign the dish, if it needs it, given that you say only a small amount of movement could have caused the problem?

    If you cross check the channels with the King of Sat link then you should see a pattern.

    I don't know how well your meter will work. The adjustment is probably so little you may not even require a meter. If you had someone watching the box's own signal meter and simply flexing the dish east/west, up/down it would indicate the direction the small adjustment is required.

    I presume RTE, TV3, TG4 are still there?

    Yes they are and he still has the majority of his channels
