IBM P202 Monitor

Here's the story, I go a free IBM P202 21" monitor in unknown condition.
When I turn it on with no inputs at all. A small box appears which flashes
between "No Input Video 1" and "No Input Video 2", then it turns itself off.
(In fact, the monitor turns itself off before it has warmed up enough to
display the box, but if I turn it on repeatedly such that it is warm, then
the box is visible)

Now, when I connect an input video signal and turn it on nothing happens.
There is no image, then a 'click' noise as it shuts itself off. I've tried
numerous display settings from 640x480 to 1280x1024 from my computer with
the same results each time. I've tried both video inputs with no change.

Has someone had a similar experience? It seems like the tube must still be
good since it can display the 'no input' dialog box. What should I do to
troubleshoot this? I have a fair amount of electronic experience, probably
all the tools I need to debug this (an o-scope etc), but I have no prior
experience working on monitors.

thanks,

Suggest you start with a simple google search. There you will find the
operating manual at:

It includes mention of your diagnostic message and suggestions for what to
do.
