does anyone know the part number or name that has to be replaced in the d1 for the screen to open and close everytime you hit the button. I know of a guy on ebay that will do it but he wont tell me what to do, he wants an assload to do the repair. I had sold this and it started acting up and the guy wants a refund and I just need to get this fixed asap so I don't have to somehow shit $500. Thanks
