No signal

[Scholesy1]

Through my Sky + multi room  box I can watch terrestrial channels but when I try to watch Sports, Cinema or even Sky News it says 'no signal'. 
Signal is showing 'good'. 
Strange how I only get certain channels and not others. Subscription is up to date as all channels work on my main box. 
Thanks in advance.

I assume that's 'no satellite signal', rather than 'no signal'. Can you watch these channels on your main Sky+ box?

[Scholesy1]

States 'isn't getting a satellite signal'. 
Confused because if this was the case how would I receive some channels when that's my only source?

thanks

Oh it's perfectly possible to receive a good signal on some channels and no signal on others, depending on tuning parameters.

Does that mean it's just a case of getting my dish checked/realigned? 
Thanks

I've reread your first post and given that all channels are working OK on your main box, it's unlikely to be a dish alignment problem, and more likely an issue with either the LNB (especially if it's more than 5 years old) or possibly cabling.

If yon book an engineer they'll be able to pinpoint the cause.
