I can toss in some learning here. My 390 just stopped playing BluRays that I own and played perfectly before. It would play DVD's fine, but on a BD would play the FBI warning, go to the menu, then when you hit play create a bunch a horizontal lines, lock up and then finally in 20 seconds power off completely. I thought it was the fact that I extended my cabling (already 30') into a keystone jack and then added a jumper. I then recalled I have never even once upgraded the firmware, so I did so and immediately it played the BD. Go figure!
