I have had my freeview decoder for 6 months. and for the last 3 months at least it comes up with a message saying that there is 'no signal' if we change the channel. This only happens between 11 am and 4 pm and not every time, but most times. It varies how long it take before we get signal again. 

If we turn it on and do not change the channel we have no issues. This is plugged in to the satellite dish outside. Our two other TV's have freeview built in and run off the aerial and we have no issues with these. 

Does any one know whether it is the decoder or the dish that will be faulty? I have no idea where to start.

If it only happens at a certian time of day, the most likely (but not only!) problem is the LNB on the dish is slowly failing. As it warms up with the sun on it, it's frequency probably drifts off slightly, making it difficult for the reciever to lock on to the signal.

Obviously - a sunny day will be worse than a cloudy day if this is the problem...

The fix for this problem is a replacement LNB.

As Runningman says, its most likely a failing LNB which needs replacing.
However why would you be watching SD Satellite Freeview when your 2 other TVs have HD Freeview built in?
