Had same problem many people were having, turns out my reciever was a clone. Purchased a reciever as my old one could not be fixed cheaply.Made sure to purchase an original vs ultra this time and have no problems at all. Alot of us thought we had originals but were fooled into buying clones.Be sure circuit board where powere supply comes in is white, tan board is a clone. None of my friends with authentic vs ultra's have had any problems whatsoever.
