samsung model bd-F5700
lately been having problems when playing discs. It would be playing then freeze. It is frozen on whatever was on the screen. Turning the power on and off does not help. As soon as it is powered up, it goes back to the frozen screen. The only thing that helps is pulling the plug from the wall outlet.
