Hi,

I know a bit about low voltage stuff, but I want to change the LOPT in an
Eizo/Nanao monitor.

I know the LOPT is faulty, as it arcs and pops when the monitor is running,
and after much effort, I've found a spare.

The monitor (an excellent F77) is probably not worth sending to a
professional to replace the LOPT as the s/h value is probably only USD
100-200...

What do I need to know about safety in order to change the LOPT? It's
certainly worth trying to repair as the picture quality is excellent, but
not worth dying for !

How do I ensure that there is no HV left in the chassis/tube before starting
work - the monitor has not been powered up for some time (month or so) at
the moment.

What special tools (if any) will I need?

I really don't like really HV stuff much (very healthy respect) and would
appreciate the advice...

Thanks from a slightly paranoid Mike...
