Hello testndtv,
contact Sonys support anyway. Usually they will try to help you even if you are not a US-customer. You description of the damage doesn't necessarily indicate a damaged screen. It could also be a damaged display controller or just a disrupted internal connection.
You can contact sonys support via
http://esupport.sony.com ("Contact support" on the left side). Explain what happened and where you live. After some emails with hints and advices they will usually tell you to send the device to their repair center in texas.
You could also try to contact your ebay-seller. Maybe he/she will be kind enough to help you. Your ebay-seller bought the device from Sony (or a reseller) and would be able to request repair without problems. Maybe you can make a deal with him/her...
