[Elecraft] lcd monitor

[John Cooper]

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?
