My Pioneer BDP-LX58-K lights up with a blue light around the switch button and on the display it says PIONEER. It even starts up when i choose that input on my TV. The problem is that nothing else work. The tray will not open either with the remote or by pressing the "Open" button directly on the unit. The player does not respond to the "Source" button on the remote. The unit is in very good condition. Has only played a dozen DVD and a few FLAC files from a USB stick. What is going on here?
