astratec retune

[fed up with freeview]

After retune of my astratec box I have all the info on the channels, all have good signal strength but I get no picture or sound. Just a blank screen. Anybody else had this problem or know how to fix it?

I would try and disconnect the power for about three or four minutes and try a re-set... get the memory cleared of any bugs.
