I got a DSm-510 from a buddy, worked good for about a month. Then on friday my wife wanted to watch a tv show, and tried to turn the unit it on. The blue light came on for about 3 sec, and was gone. I got home tried it myself, and again the blue light comes on for about 3sec and shuts off. I've unplugged it, let it sit etc. I'm guessing its broke?
Any advice?
