I did that but I didn't look at the screen. Just the spot killer light. It did not go out when I moved the connectors.

Thanks for the vote of confidence . I'm not great at this, but I know (for the most part) what not to touch. However, sometimes I'm too cautious

That's the way I did it.

Read the WG6100 FAQ, that's the best walk-through you can get.
Basic things (even when wiggling doesn't indicate anything) check those connectors with a multimeter (WHILE THE MONITOR IS OFF !) with an Ohms measuring setting. Measure between the pin of the connector and the solder island of the part that the track runs to, NOT to the soldering island of the connector itself as this is probably good since the breaks develop around the soldering island.
Another basic thing is checking all the big transistors. Are the wires still OK, do the transistor holders still make good contact to the transistor pins etc.

To check the pins with a multimeter, I 'll have to get under the board. I'm assuming I can detach and lift that board without discharging the monitor?
Level42:
No need to look at the screen. If that LED is on, there's nothing on the screen.
Yes you can !
(mmm, sounds familiar).
Maybe check if large caps still have some load on them first. I maybe a bit more "careless" on this because I'm used to working with this stuff.
Look for the obvious things first: poor contacts an either the connectors or the transistors themselves.
SirPeale:
If you want to look at the screen at the same time, a makeup mirror from a cosmetics case (like rouge) comes in handy. I carry one in my toolbox.
Level42:
No-no peale, we all know you carry it around with your lipstick and make-up............ :D

Your arms must be longer than they appear... I certainly can't hold a mirror in front of a monitor and get my arm around the side of the cab with enough line of sight to safely adjust a monitor. I don't see any mention that he has pulled the thing out of the cab.
