I am having this same issue. I have done all of the trouble shooting you suggested and the wifi and photocard lights keep flashing. It was working fine when I got it from my parents but my 2 year old started pushing buttons on it when I stepped away for just a couple minutes and now the screen lights up but will not display anything. The lights will go off for a second when you press the power button but just goes right back to flashing after that. Is there anything I can do to fix it myself? I can't find the correct numbers on the device to see if it's still under warranty, but it being a few years old I'm assuming it's probably not covered under warranty any more. Thank you so much for all your help in advance!
