Hi, sorry to hear that. Well, I recently bought a new OLED screen to repair my vita. And I failed. I have to tell you that replacing only the OLED screen is almost impossible because the screen is fused to the touch screen. So the only way to safely repair your vita is replacing the whole front piece. As far as I know, nobody sells the complete part. Just the screen or the digitalizer sepparately and there is no way to fuse them as comes from the factory. I ruined my vita in the baking process, trying to take off the broken oled. Now I have a lot of spare parts including a new oled :(
I would recommend waiting for a someone who sell the complete front assambly and then replace it.
