I have a LG 700E and after switching on the monitor's power LED blinking continueously and there is no display and no relay sound at startup, Another monitor if attached to the same system is working fine. Sometimes it automatically wakeup after 20 to 30 minute and sometime more. Please tell me a solution to this problem.

look listen and dance not matter how you performance keep it calp and trust it

if you do repairs then disassemle the monitor.where the power cord is thats the power supply resolder the main components in the power supply. cause some of the them are not making good contact on the circuit due to the age of the monitor and constant heat over the years.

problem with the monitor Display cable. it is damaged.

Normally monitor will receive 3 colors red, green, Blue signals from CPU. If one cable i.e Red wire connection is missing in display cable which is connected to monitor, Red color image on monitor wil be replaced with other fade color.
So, need the replace the display cable or display connector!

power led blinking and no display,. hout burning but lot ok

I think that two capacitors in the powers supply circuitry(incise the monitor) has gone bad. Just open and you'll see them.
This should solve your problem.Best of Luck.Please rank me appropriately. If you want any clarification, Please get back to me

LG 700E monitor's power LED blinking continueously and there is no display solutin ........

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.

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

check dry points in power supply & Horizontal, video section(CRT Neck board)
check output voltages from SMPS
check 5V from SMPS to MICOM IC

THE PRESCRIBED ARROWS ARE FUNCTIONING WELL FOR INCREASING THE VERTICAL SIGE OF THE DISPLAY OF THE MONITOR.BUT THE HORIZONTAL AROWS WHEN OPERATED ARE NOT ABLE TO INCREASE THE HORIZONTAL DISPLAY OF THE MONITOR TO FULL SIGE. PLEASE GIVE APPROPRIATE SOLUTION.
