can it be fixed - yes
can it be fixed cheaply - i doubt it
is it your responsibility to fix it - no
is it the responsibility of the seller - yes.
why spend your money on something that isnt your problem?
if you fix it - yu wont have any comeback later for anything else.
so why bother?
take it back - say it is of unmerchantable quality - ie "not fit for purpose" - and tell em to fix it!.
