I recently replaced my screen to my galaxy tab 2 10.1 and the LCD is fine it went without a hitch but when I turned it on the first time u could see the blue screen in the background then I undid back and messed with cables a little turned it back on and it just came up several colors lines goin back and forth feel like it has a bad connection or possibly the repair screen isn't good please if u know or have had this happen tell me if I can resolve this
