Before working inside a monitor, what precautions should you take to avoid electrocution? (Select TWO.)
1. Use a high-voltage probe to discharge stored charge.
2. Wear an Antistatic wrist strap.
3. >>Place the monitor on a grounding mat.
4. >>Unplug the monitor from the wall outlet.
Explanation : If you have to open a monitor, unplugging the monitor is only a start. The stored charge in the monitor capacitors is the primary concern for safety. You must discharge the high voltage charge on it using a high-voltage probe. This probe has a very large needle, a gauge that indicates volts, and a wire with an alligator clip. Attach the alligator clip to a ground. Slip the probe needle underneath the high voltage cup on the monitor. Once the voltage bleeds down to zero, you can safely work on the monitor.
You should NOT wear an antistatic wrist strap when working on a monitor. It could lead to a fatal electric shock.
Placing the monitor on a grounding mat will not reduce the danger from the stored charge in the capacitors.
