My old JVC 3000? is starting to flake out. (no surprise given it's age) The problem being is that it has now gotten into the habit of giving me a "the smart card is not inserted correctly" message. I just take out the smart card and put it back in to make the thing happy, but this is getting more frequent. So, does anyone have any suggestions on cleaning the thing? or is this the normal death dance for a smart card?
