Look, after all of what you did and you cannot get anything to work you need to ask for your money back. Did you buy this from eBay? They do have a buyer protection plan. Obviously you did not get what you paid for. Even though you took it all apart it is quite defective.It must have set up too long in extreme conditions such as an attic or storeroom. If indeed it was checked out before you bought it only minor defects would be visible. This is just a suggestion Sir. I know it is not a fix and I'm sorry this happened to you.
