THE 722K THAT I HAVE ONLY HAD FOR A WEEK IS HAVING ISSUES, STARTED A COUPLE NIGHTS AGO WHEN IT RESTARTED TWICE, NOW TONIGHT IT IS REPEATEDLY RESTARTING, WHEN IT ACTS UP I GET A GREEN SCREEN THEN IT RESTARTS HAS DONE IT SEVERAL TIMES NOW. AFTER THE LATEST RESTART IT DID STAY ON FOR A FEW BUT IS COMPLETELY UNWATCHABLE. I ALSO HAVE A 622 AND IT IS WORKING FINE. I HAVE INCLUDED A COUPLE PICS. HAS ANYONE ELSE EXPERENCED THIS CONCERN? IF I BRING UP THE MENU OR GUIDE THEY LOOK OK.
