700e Lg crt monitor problam power on eht on but not display


The normal crt monitor have a demo display when you unplug the vga cable to PC like this image below.. fd6b6b9.jpg
Note:
If the crt monitor green LED light steady and heater beam have light, the horinzontal and High Voltage supplied to tube is completely good. If you encountered this problem just focus on video section of crt monitor. But before you start... find the flyback transformer behind this they have two controls screen & focus. After you found it plugin the monitor use plastic precision or small screw philip driver for safety to high voltage at horizontal area choose screen control rotate it to clockwise direction follow this....
5b5166c.jpg If the display responses or from dim to lighter 100% you have a problem to ABL find this at the bottom of horinzontal section near at flyback transformer pins trace the line of ABL for dried solder, open resistor if nothing happen find the Video IC at chroma section and replace it. follow this...

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.
