EZ Flash Omega stuck on Game Boy screen

[zardyboy]

Hi all, I'm using an EZ Flash Omega to emulate games, have for nearly a year. Played last night, no problem. Turned it on less than 12 hours later to play again, and now it's getting stuck on the Game Boy screen. Nothing happened between turning it off last night and turning it on this morning. There is no Nintendo logo. I've taken it apart, cleaned pins, tried the paper trick, etc. Nothing. This is really frustrating! Can anyone help?
