ok so i have my panasonic cq-c8401u head unit only used it like 8 to 9 hours max and after letting the girlfriend use my car for a few days it no longer wanted to do anything it would power up but thats all i just replaced it with a pioneer deh-p6700mp and kind of forgot about the panasonic for awhile but now i have a new car with a shitty kenwood in it and id like to get the panasonic fixed theres a local place close to me that does repairs like that but before paying like 20 bucks to see what he thinks is wrong i would like to see what some of you have to say about what you think could be wrong and about how much it would cost any bit of help would be greatly appreciated
