Here's what it's doing. I turn it on and the display reads "Dvd 3910" then turns off. The dimmer button does not do anything on remote, Batteries are fine because you can open and close the tray with it. whenever I push a button the display will come on for a second and turn back off. I've tried turning the batteries around and doesn't help.
Here's the second thing, I am using a Firefold HDMI cable, new 42" LG, the purple denon screen does not come up, in fact all it says is no signal as if it weren't plugged in at all. I do have the TV on the right input and have actually tried both HDMI inputs just for kicks and nothing. And have tried switching the cable in both inputs, nothing. it will not work with Component cables or composite cables either. I have unplugged and turned off, turned off the main power switch and reunplugged again and again and still nothing.
Please help, it started with not reading Cd's then running very loud (still does up until quitting) to this. I would replace the laser anyway so it will do Cd's again but then I have a 2800 that does that fine. Do I need a new laser? Help please.
