Hi Don,

thanks for your suggestions. -Yes, i switched on the PS for the tuner 
first, and yes, i used the external cable also, i tried the internal 
connection just as an additional test.- BUT, i recently found the faulty 
part: U8, the 5V voltage regulator, was defective! And -surprise, 
surprise- without internal 5V the tuner would't work:-) I replaced it 
with a spare part and it runs perfectly!

So thanks again and hpe cuagn,

73, Rolf DL1KJ
