I just can't figure out the puzzle of how to get this thing open. It's
a "Visual Sensations" VS-7i model from KDS.

Their website didn't help. How do I even go about asking for help on
this group, since you can't see the monitor? Anyways, I'm hoping
somebody might offfer some clue, or tell me how to give more info in
order to get back some clue.

The underlying problem is that the monitor just goes black sometimes.
There occurs much more often a small disturbance on the screen, like a
sudden, narrow horizontal glitch that lasts a moment.

The likely source of the problem is the power switch. It is misaligned
in it's round hole (the corner of the case had been propped on some old
bills, and over a long period of time that apparently had made
something shift inside). When the screen goes entirely black, I have so
far (knock on wood) been able to bring it back by repeatedly working
the switch.

May have a crack on the circuit board

I have an KDS Avitron that may be similar in design. The probably even
sounds similar.

The cover has some latches at the top edge. Look in the top seam for
some small holes. Push something into the hole to release the latches.

The power switch is probably just broken loose from it's mounting. It
likely isn't even your real problem. After fixing the other problem
just glue it back on with some epoxy.

On my monitor the blanking was caused by a failed solder connection on
the flyback transformer. If hitting the monitor makes it work you have
probably found the problem. Check all of the large solder joints.

Hope this helps.

you are perfectly right on all counts, Shawn. Thank you very kindly.

Would it be correct to think that such a problem is likely on the
larger joints, because the larger joints experience more heat?

Larger joints are under more stress and are more likely to not receive
enough heat or solder during assembly.
