It sounds like a defective LCD to me. If its turning Blue its either losing connection (cold solder) or is grounding out (pinched wire). As long as you didnt open it up I think you should take it back and get a new one while you can.It works real good and has a great picture in my book, but after playing for about 1 hour the display turned kinda blueish, has gone back to normal a few times, but not very much. Is this a problem w/ the LCD or does it have something to do w/ my connections,.........I have tried the search function but have found nothing about blued screens.
Thanks in advance.........John S.
Good luck with it either way!
