Default CRT monitor: flashes on screen and burnt smell

Recently, my Hyundai ImageQuest Q910 19" monitor has been acting
up. Occasionally, there would be flashes across the screen,
similar to what you get when a fridge shuts off nearby.

Over a week or two, the flashes become more frequent. One day,
there was a big one, spanning maybe 10% of the frame. Later that
day, I smelled something burning in the monitor and turned it
off in a hurry.

There is no obvious damage inside. Where would you look first ?


Does it actually still work ?


Yes. I've had to use it a couple times and had no problems,
though I haven't left it on longer than necessary (i.e. about a
minute each time).

First suspicion would have to be bad joints. Could be almost
anywhere such as PSU, HOP stage or CRT base. Have a tap around
with a long insulated stick such as a piece of wood dowel. If
you do it in subdued lighting, you might even be able to see
the arcing from a bad joint.


Thanks. What's HOP ? Horizontal Overnight Permission ?
