Default [Q] Totally bricked TF101G, deleting memory?, low-level recovery? Please help!

Hello Everybody,

my TF101G won' t start after drop down. I opened it and checked all cable connections, but nothing found. The display is still black even if I put it on current or PC-USB. Now I want to sell it on eBay for repair parts. A problem is to delete my personal data. is there any chance to delete it without starting the tablet? Please help!
