One of the tuners on the first TBS6981 card is not working annymore, could not get lock, on most of the channels (Dutch SD quality channels). Also german free HD channels are not working. BBC channels are working.
I tink it is the card, because after switching with anouther card, there is no problem.
My system is debian linux 64 bit, it always worked, but last week is starts with difficuties to get lock, or the video quality is getting poor.
Is there a way to test the cards? Wat can i do?
