mt wont turn on,not the usual battery issue

[a fraking toaster]

so i bought this phone off ebay marked as broken for 6$ and its in pretty good condition everything is there but it wont turn on.i figured it was the normal dead battery issue that everyone has but i dont think it is.i managed to charge the battery externally and let it sit for a bit plugged into my pc and done just about everything else iv read to revive this thing but nothing has worked.the charging light doesnt even come on.i havent found much info on how to revive this phone other then the dead battery way which proved unuseful.so any ideas or help will be appreciated.thanks
