Notes to help the hobbyist get their color TDS oscilloscopes display working. Hope this helps you out.
Danger, high voltage...! Take the time to insure you have descent grounding and do some reading on safety when working on CRT's. Trivia really, if you have no plans of working on one of these. Have someone near enough to notice if you keel over. If this is your first time, I'm not kidding.
These displays by the way are some of the very best color CRT's ever made. The Tek.com/forum has more info on working on these and LCD monitor replacements (not to be confused with the color LCD shutters this CRT uses). Many of those posts are by yours truly.
Good Luck
