Thanx for replying.
All the fuses are ok.
The casstete player works when a cassette is put into the slot no music can be heard. The sat screen lights up but nothing can be seen. all the switches around the screen light up but nothing works.
I have put a none sat cassette player with heaters in it and they all work perfect except the aerial does not come out when i put the orignal sat screen back in same problem
