Maybe Claude at Dishstore can help ??
When I received my replacement 622 from E* it arrived damaged due to the poor way it was packed. (Shipped in only the flimsy box, no "box-in-box" and UPS left it on my doorstep that way. I didn't notice the damage until several days later when I finally unpacked it.) The unit was crushed-in a bit at left rear corner, both the lid and rear panel. This was back in the days of many HDMI port problems and the HDMI on this one seemed OK. I decided to try it out for the long term and it has been flawless otherwise, so eventually I straightened the lid and back corner myself and reassembled it.
Welcome to the OP, BTW...
