Yes - I mentioned this before on here.
Back in the mid-late 90's Toshiba ventured into the desktop PC arena with some quite nice units (and as a digression I LOVED Toshiba laptops - so well built and performed better than the then top-range Compaq's and Dell's etc).
A lady called in that her monitor had gone pop one morning.
A replacement was duly sent out. A week later she called to say that the same thing had happened, so once again a replacement was sent out.
Another week passed...yep, same call comes in. This time, Toshiba instructed that they wanted an engineer to visit and watch what was happening as a pattern had been noted - the call came in mid-morning every Thurs (or might've been Friday), so the engineer was despatched with a new screen and instructions to the lady to ignore them and just do what she would normally do.
It turned out that she had a potted plant on top of the screen with no bowl or saucer underneath. Every Thurs morning she would water the plant and a couple of hours later, the water would find its way through the pot and drip into the screen.
When the screen was being replaced, she'd obviously moved everything off so no pot to be seen and just enough water through to cause the damage but not enough to spot obvious water ingress.
Apparently she'd done this for years but the old screen must've had vents in different places as it never happened on that.
