One comment...if you don't have the correct cable and a system that is set
for the correct refresh rate, it may appear that the monitor does not
work. Be sure you have compatible equipment. This was a specialized
display.

Josh;
I have a DEC VR150 that is nearly functional; shows full screen but the
H/V are not in any sync at all. Would love to use it with a VaxStation
3100.
Opened it up and found it quite a complicated monitor, not like a simple
PC monochrome monitor.
Purchased a microfiche manual off ebay, but haven't been able to view it
yet.
Eager to hear how you do with your larger monitor.

Hi all --
Picked up a non-functional but otherwise nice looking DEC VR260 (19" b&w
monitor) on the cheap, hoping to use it with my VAXstation 2000. From
what
I've read, these were never the most reliable
displays. Curious if
anyone
has any information on common failure modes, or
has service docs
squirreled
away somewhere. I've at least found
schematics, so I have something to
go
on, but it's not exactly the most
straightforward design I've poked at.
Right now when powered up I hear a repeated low hum from the transformer
followed by a soft ticking noise so I'm guessing I've got power supply
issues at the very least. Unsure what I should expect the monitor to do
if
it's not being fed a valid video signal (I
haven't yet tried to hook the
VS2000 up to it) -- whether it'll go into free-running mode or do mostly
nothing until it has something to sync to...
Thanks as always,
Josh
