My Bush DVD 2023 player was ok until I Inserted a brand new dvd disc & got a message "Incorrect disc format" Since then when I insert a disc it takes 60 - 90 secs to Load, makes a couple of clunking noises then says "Incorrect disc format". Does the laser need adjusting, if so, how? Or can the player tbe reset? I can read circuit diags but am not familiar with DVD player principles.
