The same thing happened to my 1084s...
The display got shrinked to a line, poof, BANG, poof,
*BANG*.
ALL the caps in the power supply were blown...
And when I replaced them, the LMs said *HELLO!*,
by blowing up... :-)
Once, I wired a large capacitor and blew it up off the
balcony to annoy a stupid neighbour... :-)
I've also seen PCBs catch fire and *FELT* a PSU make a nice discharge on my finger... It was painful
but fun, watching a spark between my finger and
2 contacts... (No, I didn't TOUCH).
