Finally after 5+ years first real issue came up, the screen stopped working, some yellow lines running vertically. The screen had a single blue vertical line in the middle for a while but it didn't affect the operation, now it is pretty much dead not responding to touch. Quick search did not reveal anything. Fortunately I can still charge. Is there a known fix? I have a feeling it is not the screen itself but the controller.
