- Did you try hitting it? No seriously... If it happens again, try to hit
- it, gently at first ofcourse, and see if the problem goes away.... If it
- does, than it's probably the power-transformer inside your monitor.

- :-))) Oh boy, I can see you sitting there behind your monitor: your forehead
- is filled with sweat, your clothes aswell... Just to see how far you can
- push it until the final blow:-)

- I've seen quite a number of monitors which had similar problems...
- screen blackouts, cracking sound during operation... flickering... all with
- the same cause: the transformer... This transformer which supplies the
- power for your monitor gets **VERY** hot, so hot that over the years it
- litteraly melts from the printboard:( You could try opening your monitor
- and see if you can find this transformer, its a big bulky thing, you can
- hardly miss it:) (apart from the screen-tube ofcourse:) Check the printboard
- to see if the soldering of the transformer is cracked, poor, or even
- missing. If it is... RESOLDER it, don't be sparing:)... you should be able
- to use your monitor for a couple of more years again then...
-
- I sure hope this fixes your problem, GOOD LUCK!!
