Did you check the fuse inside of the control head (F902)?
I've attached a file I found in my collection of D700 documents
that might be helpful.

I was listening to a repeater on my D700,
walked out of the room and came back and it was off. I tried
turning it back on and the screen flashed some black
momentarily but nothing else happened. No backlight or signs
of life from the radio. Any troubleshooting thoughts? Is it
possible to get the radio to power up without a control head
attached to see if it is control head or radio? All fuses seem
fine and power cable appears to be getting power. Powersupply
seems fine and is still powering my other radios fine.
