Grundig no signal being received

Hi
I have a non subscription grundig 200 series that until recently has worked
fine but lately I cant receive Sky News on. I tried adjusting the dish to
bring the signal strength up to 50 % (currently at around 25 with signal
quality at 50) but to no avail but when I connect a newer box to the same
dish the signal strength is around 75%. Is this a common problem with older
grundig boxes and has anyone any knowledge how to fix same. I know this
question has probably been asked before but I don't know where to find the
faq's for this news group.
any help would be greatly appreciated

Does the newer box get a picture ? The readings arent that important to
that exent, each box varys.
