Someone asked me about these oscilloscopes. Apparently he has a dozen
of them that do not power up. No display or backlight on the LCD. Yes,
AC power is set correctly. I haven't seen them so don't really have any
more info.
Anything common with these?
Thanks!

Electrolytics, almost always on these, throughout the PSU, input
attenuator board, XYZ board. Usually all will need replacing, can
total 30-40 caps. Tedious job for a 50/60MHz scope. Couple of
unavailable IC's in the preamplifier fail regularly causing offset
traces. Backlights usually fail on the LCD but you won't know until
you get the scope up and running, its just a mini filament lamp,
available from www.jetecnet.com

Thanks! That's exactly the type of information I was looking for.
The owner won't be happy.
