Assuming you do eliminate domestic causes, you could have a monitor which
has a bad connection or a component that is breaking down - arcing
internally. At this point, I don't know that I would do anything other
than keep an eye on it.  Even at 10-15 minutes, it will be difficult
for a repair technician to find the cause and they may end up charging
for a 'shotgun' repair approach - keep blindly replacing (expensive)
parts until the problem goes away.
