My pentax p30 is not winding on?

Hi I have a pentax p30 and whant to sell it but the shutter will not go down and it will not wind on. there are no batteries in it at the moment could that be the problem? Should I try to undo it myselfe to see if I can fix it, because it would not be worth getting reparied.
I have been trying to find some can you sugest some where ?
