Hi all -- I have a problem - Please bear with me as I'm a newbie to these forums, and if I don't post everything you need to know, chastise gently and ask me ;-) I have a Velocity T510 that's been given to me as a DOA to see if I can recover it - I know nothing about what's been done to it - I have no reason to believe that anyone's tried to Symptoms - Backlight comes on Nothing appears on the screen _at all_ . When plugged into a USB cable and a Windows machine, the USB does not appear to detect -- at least, Windows doesn't pop up and say "hey, I've found a new device here" Nothing seems to be wrong with the tablet other than that - no cracked screen, etc. The 'up' volume button appears not to 'click', though all other buttons properly do. Reset has no effect. What I'm wondering is how to do any further testing to determine whether the unit is _trying_ to do anything at all. I don't know if it's stuck in some boot-loop, totally dead, or what. Ideas, anyone?
