Ok I started a thread yesterday stating thet my LCD monitor had melted at the base…I thought it was the Liquid Crystal Display and was apparently mistaken…so today I have my camera so here it is:
The way the rust is distributed, it looks like the spill came from inside the case. But for something corrosive to drip down the neck of the stand, traverse the hinge, and collect around the foot - I would think you’d be seeing other signs of it.
You mentioned high humidity in the office. Is it possible that condensation collected inside the stand and dripped down onto its base?
That is a distinct possibility, moisture could have been captured under the stand and corroded the base. However, the corrosian encircles the base as if it were dunked in some liquid, and it was not.
It is certainly a long term problem with moisture. I have seen a monitor die from a mouse peeing into it. I’ve also seen rust like that on metal from mouse pee exposure over time. Any animal in the house is a suspect of that damage. High humidity condensing there could be the problem, or a ceiling leak. Somebody with a drink or watering plants is suspect. You might have a leaky bottle of Windex set on the monitor while you clean. I’m going for the animal pee as my top guess.
