Hi there. Can somebody please help me.

Im driving crazy. Something went wrong and now i have a bricked tablet. Absolutly nothing appears in the screen. Not even android, arnova logos. The tablet just seems not to start.  I have this brick at home for almost a year, because i cant handle the problem. I know its old and i have another tablet but a really wanted that thing to work. Can somebody in the name of all thats sacred help me? Thanks in advance
