Answers :

The monitor is probably on protection.

To start unplug monitor\015\012from power and from computer and test computer with different monitor\015\012to find out if it is monitor or computer fault.

If it is computer fault and no video signal , then test:

\015\012
    \015\012
  • Video cable.
  • \015\012
  • Video adapter on PC (sometimes integrated on motherboard)
  • \015\012
  • Motherboard.

If it is monitor fault , then the monitor is on protection.

When on protection you keep having a flashing\015\012led on front of the monitor , and monitor turning off by itself after a while,\015\012that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the Monitor goes on protection there are only two possible causes.

1The\015\012internal circuits are jammed because of electrostatic\015\012charges accumulating on capacitors, or because of a wrong voltage read\015\012by the main chip on your monitor controller board. this started the\015\012protection circuit.

2 The protection circuit detected a wrong\015\012voltage or a broken contact, identified an internal fault and kicked in\015\012, starting the flashing light.


If\015\012you are in situation one, then the monitor will reset just unplugging\015\012power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common\015\012faults\015\012that can occur are a blown capacitor on power board, faulty inverter\015\012board, faulty input board, or a fault on LCD Digital Controller board.

Check also\015\012the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you\015\012can get same flashing state because of the video cable.

Try moving the video cable, and if the cable is not built in, then also try a replacement cable.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.\015\012\015\012
