Backlight not working normally but occasionally flashes on
Ok so I have an iPhone 3GS to fix. The backlight flashes on for a split second when I reboot then phone but apart from that it doesn't work. I also managed to get the backlight to stay on for a minute today but it eventually went out. The phone has had water in it previously as the top water damage indicator has been activated. Does anyone know what component is the culprit here?
Is this a good question?
