Report "I have a Samsung HT-D4500. It stopped working (Had "loading" message only) The store replaced the Motherboard. When the device came back it worked for 2 days and did not switch on. No power whatsoever. I packaged it and sent it back to the store later in the week. The guy at the service centre claimed that they plugged it in and watched the dvd that was still stuck in the drive. They had it playing for the week and sent it back. I had it back for 1 day watched 2 movies (Thursday), and went away for the weekend. On the Sunday night, it wouldn't switch on. Sounds like the same problem all over again. I've unplugged the device, thinking that perhaps a capacitor or something is holding a charge for a few hours but still no power.... ...any ideas"
