Bringing it into a shop and leaving it for a few hours does sound like too much of a headache.
DOESN'T sound like a headache, I mean.
You have not put anything in an electronics shop lately,have you? Expect it to be there weeks,if not months.You already know what they are going to charge just to look at it,to repair will probably cost more than a good used unit.Keep ypur eyes on the classifieds here and you will find something much better.Just a thought,good luck.
