Osborne One -- No video.

There must be a shunt on the video edge connector that comes out at the
front middle of the case. It just connects the contact on the bottom with
the contact on the top of the circuit board. I can email you more info
tomorrow if you need it...got to run now.

Subject: Osborne One -- No video.


Hello all,

I recently acquired an Osborne One, but it seems to be having a video
problem -- as in no video at all. I did the obvious - played with the
brightness and contrast -- but still nothing. If I press a key on the
keyboard, the floppy starts seeking, so I assume the rest of the computer is
at least partially working, but I get no video output at all. I have NO
docs or schematics, so it's a bit hard for me to test stuff out. The CRT
make no noise at all when power is either turned off or on (no static or
hum, or anything else). Also, I took the cover off, and carefully looked
inside while turning the power on, and the CRT didn't light up, or have any
other response.

After powering down, a very careful disassembly showed no physical damage
signs -- no burn spots, missing components, broken wires, etc.

Any clues?

This is the blue case, with the modem, and a composite video jack (female
RCA jack) in the bottom right....
