Monitor 'popped' - beyond repair?

Absolutely you can fix it yourself and most components should be available from Digikey or Mouser.

You will of course need a multimeter, soldering iron, and a little skill.

Your first task is to disassemble the unit and take a look at the boards. Since you heard a "pop" you should be able to see some sort of physical damage somewhere on the boards. You can also do a sniff test and usually find the damaged component as well. Most likely the pop was either a capacitor or transistor.

If you do not want to tackle the repair yourself you could always find the faulty board and see if there is a replacement on eBay or Amazon, or find a local computer/tv repair shop and have them do it.

Good luck!
