Buy a new one, mine broke just within the 3 year extended warrenty then again 6 months after repair. It's not worth the repair costs. The problem is the type of solder used which slowly burns away and leaves cracks. Reflowing it (heating it so it melts and resettles) will extend the life time but it's not a real solution. It will start re-breaking sooner and sooner after each additional 'repair'
