Best step is to go back to seller for a refund/replacement.
In my humble opinion you have corrupted firmware. So you need to find a full firmware to reflash to your player. Yes you may have hardware problems but the hour glass says "firmware" to me. YOu need to identify the chip numbers particularly the square one approx 1cm square, the screen size, and see if you can find a match and try reflashing (instructions on this site).
Again in my humble opinion there is no point in trying to solder or resolder anything as the geometries are far too small for any equipment you are likely to be able to lay your hands on.
Sadly as I also have found out, the hunt for firmware is very frustrating - it is likely to be v timeconsuming & not too likely to end in success (see most of posts on board).
