Question about Sony DAV-DX255 System
Home theater says 'push power protector'
I brought the unit to an authorized Sony repair depot and they concluded that all the power transistors were fried. They replaced the system board under warranty (at no charge) and the system has functioned perfectly since. Thanks for your help. -Steve.
