Question about Envision 19" Widescreen Flat Panel TFT LCD Monitor

1 Answer

When I turn my monitor on, the LED light at the bottom blinks off and on, but there is no display. I keep turning the switch off and on and finally the screen begins to display. I have a warranty, but can't find it and Staples (where I bought it) said they can only go back a year on my card. Is this just a switch problem or is there anything I can do? ♠

LG 700E monitor's power LED blinking continueously, no display


The monitor is probably on protection.

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

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

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

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

When on protection you keep having a flashing led on front of the monitor , and monitor turning off by itself after a while, that 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 internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

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


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

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

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

Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can 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.

Samsung Syncmaster 710n no display and no LED light


The power button should be on the FRONT BOTTOM RIGHT. and there should be a little led/light next to it. make sure everything is plugged in correctly and press the power button, the led should light up, and then boot your computer.
