RE: Damaged?? zx10 opinion needed
The scratches on the board certainly indicate that the unit is not brand new. Sometimes electronic boards are reworked after manufacture to repair or replace faulty components. There are definately some solder rework scorches on some of the component's solder pads. Of course this may have been done before the unit left the factory or in some cases by sub contractors before sale. Personally, if that board
was sold to you as new I would return it and ask for a refund due to the scratches which may be deep enough to break the circuit.
Good Luck
