Trying to toggle the power switch and pressing the reset button on the rear has had no effect. I have sent an email to Sony Repair and am awaiting their reply, but in the meanwhile I was wondering if anybody else has had a similar experience after the upgrade and how it was resolved.
When the 500 I had sent out came back, the battery was drained and needed to be charged. So I'm thinking yours may be the same way. Plug in the AC adapter and give it a charge. While it's plugged into the AC adapter, you should be able to boot it up and read away.
