I recently bought a used projector off of eBay for a few hundred and then I bought a Philips HTS3565D at WalMart the other day to complement the projector. I had to splice some of the speaker wires in order to make them long enough for the speakers to mount in the correct spot. I put everything on the surface of the wall to test it and then eventually was going to run the wires through the wall/ceiling. We watched about 3 movies on it that night and it sounded great. The next morning I went to use it and there wasn't any sound and when I touched the volume control on the head-unit it froze up and then wouldn't turn off/on even after several attempts. Philips CS was great and shipped me out a new system. My question is, is it possible that I fried the unit by maybe not hooking up my wire extensions correctly? I tried to be consistent throughout each splice but I guess I didn't understand that speaker wires had separate polarity. Please help b/c I'm going to have to splice the new system when it arrives as well and I don't want to do the same thing again!
