Monitor short-circuit 3 times in a row

I sold a computer with 17" monitor some time ago. After a few months I got a call that the monitor was now giving a vague image so I swappad it for another 2nd hand monitor, which gave up next day (after some knispering and banging inside, sounded loike a short-circuit) so I swapped it again, all free of charge:( by the way.

However I just got a call.....this monitor also collapsed. Since the last one was the monitor I had owned myself for two years, completely to my satisfaction, I start to wonder if something might be wrong: with the computer instead with the monitors? How can  determine what's wrong there? By the way I'm not an electrician.

It is most likely the electrical outlet that the monitor is plugged into for power.  If the eiring in the building was not done properly or had extensive modifications done to it that exceeded the design, there could be power fluctuations and surges that will damage a monitor.  The fix is to correct the wiring situation or get a UPS and connect it to that.  A video card has signal level voltages (around 1 volt) which would not damage a monitor.

oops: eiring => wiring

A UPS will balance the power load much better. Also, have the user switch outlets or residences for that matter.

To add to what Callandor said:
there might be something running on the same circuit that the monitor is on, that is causing the fluctuations and/or surges.
