Help..satellite receiver box on blink

A couple of weeks ago all our English channels came back just like thet after having lost them for months with the satellite changes.. Now just as I, m enjoying Emmerdale again the stupid receiver box has gone on the blink, won, t switch on or off with remote or by the box, just keeps flashing non stop, have tried unplugging, replugging it back in but no change. So, what I would like to know is do I just replace the receiver box and can it be any box, I don, t want to buy it on the internet so will be buying it here in France, just wanted some advice on what type to buy etc, many thanks.

Thankyou for that Doreen, very helpfull.
