Hello, first I would like to say thinks in advance for the help! After leaving the receiver on all night I walk into the room to find one of my HR24s makes sounds like when you first plug it in (fans start, i think under the noise of the fan I hear the hard drive spin, etc) for about 3 seconds. Then it goes off completely very briefly, then it tries to boot again and makes all the same noises, then it briefly dies again, over and over. IS this common enough where someone can tell me there is a 95% chance it is the hard drive, or a 90% chance it is the power supply? I own all of my receivers and I am the second owner on all of them so I'm pretty sure I'm allowed to do anything and I have no kind of warranty.
