I picked up a Sony 17-inch monitor that had been returned
from a trip on a sonar survey boat as "non-working".
Thinking that a 17-inch screen would be nice, I had a look
inside. There were big blue glowing sparks inside the
glass of the tube neck. Closer examination with the power
off revealed that the neck was broken -- wiggling it made a
horrible crunchy "broken-glass" noise. The weight of the
RGB video amplifiers (supported only by the glass) had
snapped the tube.
