Hi all! I know that there have been a few threads on this, but I still can't find an answer to my issue. I have an original S3 that just won't boot. I have replaced the HD with a new drive (with the 648 image), I have replaced all of the busted capacitors, and have even gone so far as to switch out the power supply with my other S3 just to verify that I installed everything correctly. But still, I am stuck on the "Welcome, Powering Up..." screen. Any suggestions? One thing that I didn't mention was the fact that I had an external drive hooked up to the unit when it died - I have not plugged that drive back in as I suspect that its dead as well. Could that be my issue? Thanks!
