I dropped my 7 sylvania android and it won't cut

It's possibly you fried it's tiny mobo by dropping it, you could always take it into a place such as laptop X change and they can replace the capacitors on it, or the whole mobo in general.

If you have a warranty or insurance on it, then that always helps too :) I apologize for your phone, I hope you find a fix for it soon.

If you're the technical type, you could also order replacement parts on eBay and just fix it yourself, but I warn you this is really NOT easy, even for those who build computers since there is a risk of breaking the plastic clips that hold the phone together, there is also risk of damaging wires and such other smaller chips since they are pretty fragile.
