Y1 something? Sorry, but you have a bad case of a battery leakage. You definitely should clean this board AASP and then look for damaged components. Also the picture is too blurred to be any good.
If the board is not too damaged, you can then proceed with recap. Clean the board first with soapy water and then with isopropyl alcohol a few times.

I hope that you'll be able to get it running, but this picture doesn't look too promising.
