hi, ive had my rns-e now for several months. recently it started to play up. the screen goes all white and has lines accross it. when this first happened, if i tapped the screen edge it would correct itself. now however it seems to happen more often and its allot harder to fix. here a pic and a video to show what i mean: VIDEO link: has anyone come accross this problem.?? is it repairable.? DIY fix.? saw an auction on ebay which offered repairs to RNS-e's but they quoted £80-90 from a seller to repair but is that my only option.?? guessing something is loose in the screen because if i open the screen and push on the rear of the casing it goes. any help greatly appreciated.
