I've always been very careful with my TVs to not turn them up too loud and blow a speaker. But I had a guest at the house a few weeks back who turned it up very loud and now my bass speaker in my PN60B650 is rattling. I don't want to use an external speaker setup, I've always been happy with internal speakers, if they aren't blown. Does Samsung have a service that fixes issues like these? The last time I took a TV (a WEGA) to a TV repair shop, they left screws out of the back of the tv.. should I attempt a repair by myself or would a run of mill audio shop be able to fix this for me? When I have a TV with blown speakers, it's so annoying that I'm willing to sell the TV..
