All three LED's blinking, no video

I have had this monitor for awhile with no problems. Recently, I moved my PC and monitor. When I reconnected the video cable and power cord, the three led's (1, 2 and Power LED's) began blinking. The power LED blinks an orange color, and nothing displays on the monitor.

Not even any error message? Do you still see the logo of the manufacturer when you press on the power button?

My son moved the monitor from one pc tp another and it worked great for a few days. Today he turns it on and the screen is black and blinks every couple of seconds. I have restarted, unplugged and checked...

Guess to narrow it down, can he put the monitor on another computer to see if it still works? Also putting different monitor on the current computer might give you a few more ideas. At least then you will know have a better idea of where the problem lies. Hard to diagnose this stuff unless you are the one sitting in front of it.
Hope this starts you in some direction.

Monitor wont power up

It is possible especially if it has a loose or slightly faulty component and moving the monitor has caused it to fail especially if you bump it in the move.
Does the power LED light up when you switch on the monitor?

Lg monitor studioworks e 700, ligh is blinking

The most likely cause of your problem is your display card and not the monitor. If the monitor led is blinking there is most likely no VGA signal being sent to the monitor. Plug your monitor into a PC that you know is working and check to see if it works through the other pc.
Let me know if this solves your problem.
Best wishes,

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.

Blinking green power light and monitor doesn't work

I recently had the same problem occur on my LCD Panel and this is the response I received from ACER.

Thank you for contacting Acer America. I apologize for the inconvenience that you have experienced. If the green power on LED blinks rapidly, it means that the monitor is not getting any signal from the computer. It is possible that the monitor may have faulty internal component, I suggest that you send your monitor to a local repair shop to have it tested properly.

LED's blinking, no video

Your C5707 transistors in the monitor have failed. Suggest replacing all four with the Sanyo C5707 transistor. A common problem.
