HP48 won't turn on (nothing on display)
I've been mulling the purchase of an HP-48 and found an SX which the seller says won't turn on. I instructed him to try the following:

1. Leave the batteries out for 48 hours then insert them and see if it powers on.

2. Reset by removing the upper right rubber foot, as viewed from the back side. You'll see a small hole with the letter R next to it. Insert a paper-clip as far as it will go, and release.

3. Press ON, hold down A, press and release F, release A, then release ON.

They performed all the above tests but still nothing will appear on the display. Is this truly a dead unit? If so, considering the appearance is pristine, what could be wrong with it? (In other words, is it easily fixable, do you think?)

Thanks.
