  • Don’t plug in too many appliances at once to avoid a voltage overload.
  • Check the frequency effects with an electrician.
  • Replace any capacitors that have reached the end of their useful life or have become degraded.

5. The Monitor Is In Safe Mode

If your Samsung LCD monitor enters power save mode, you may notice a flashing blue light on the screen display. The following are some of the troubling factors that have contributed to this crisis:
