My six years old Sony G400 monitor exhibits following problem. After
power on (or going on from standby mode) the screen produces several
short flashes for approximately 15 seconds. The flashes are extremly
intensive and have blue color with nearly ten times higher brightness
than normal maximum brightness. After this sequence monitor operates
without any problems.

The monitor was already repaired two years ago (different problem) so
another repair probably woudn't make sense. Should I fear it can
explode one day ? :-)
