[Elecraft] lcd monitor

[Mike WA8BXN]

I had a monitor with somewhat similar problem a couple years ago. Turned out
it had a bad batch of electrolytic caps in it. Look at the caps and if any
are bulging, replace them all. I say all because the ones that may be good
now probably will get bad in the future. Suitable replacements can often be
found at radio shack, perhaps at a bit higher voltage than the originals. 
 
Here is some more general info on tha cause (at the end particularly):

Or search for "bad capacitors".

Slightly off topic question here, have a monitor that the green light blinks
and takes anywhere from 5-15minutes to turn on. I have found out today that
if I take my Heat Gun(hairdryer on steroids) and blow through the holes on
the back it fires right up. Ive always heard that you can spray freon( or
whatever is in the cold sprays) on stuff to make something that was
overheating cool to work right that way you found what was bad in a circuit
but never have I heard of heating something up before. I live in southeast
Texas so when I say cold I mean its been 40 degrees or so. The power board
and signal board are mostly smd stuff Ive also read of some people baking
their circuit boards in an oven, anyone heard of this?
