2008 GW NAV/comfort. Had pixels going out so I decided to replace NAV screen. NAV worked perfectly before replacement. First screen was from ebay at $312.00 serial # LQ065T9BR54U. After installing screen it was a white blank. Checked online was informed that i needed to replace it with the original serial# LQ065T9BR55U. Located one from China (Sharp Japan) Installed that one with the same result. I then decided to reinstall the original screen with the same results blank screen. I have tried several recommendations ie replace flasher fuse. I know I am not the only one with this problem, any help would be appreciated.
