I recently purchased a silver psp from an ebay store few weeks ago and just received my package. However, when i opened and turned on my PSP, i noticed there's something wrong with the screen. On the right side of the screen, it seems a little blurry and there seems to be bunch of lines running vertically and it's hard to read some texts, like the date on the top right corner. Is there a way to fix this or should i just return it for a refund or an exchangment?
