Question about LG 700M 17" CRT Monitor

Open Question

Monitor does't start with power on. It starts after 4-5 minutes.

When I start my CPU then my monitor's green light starts with blinking & after 4-5 minutes monitor gets started. I am facing this problem from previous 5 to 6 days. Before 5-6 days, I had formatted my system perfectly. I have faced this problem first time in my life. So i want to know, in monitor does any part get expire after certain time period. Because I have formatted my system before many times but this problem is occurred first time. So I don't think that this problem may be due to format the system. I think some part of my monitor get expired. I want to know exact reason of this problem. I have purchased my system on 30-sep-2006. Please solve my query with proper solution. Thanks!

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.

SOURCE: monitor wont power back on,

It sounds like something to do with auto shut down or power saver mode on your monitor. you may have to replace the power supply in your monitor.
It could also be the VGA cable or the VGA connector bent pin.
Step through the menu to see if there is an option to disable auto shut down.
Hope this helps

The cpu is running,the motherboard is with green light inside,but the monitor blanck

what king of monitor you have., crt or LCD, does the monitor led indicator has a green light, is there any beep when starting the cpu? how many beeps you have heard when the cpu was starting?.

if there is no led indicator light in you monitor the posibilities of that is the monitor was the problem.
solution: try to check your plug in monitor if it is properly inserted in the power plug or in the vga plug correctly.

if when you power the cpu and your monitor led indicator, turn green and back in the standby mode. listen to the beep sound of cpu if theres any.
solution: try eject the mem card. in the slot and clean the contact with the eraser. and put it back into the slot again after you clean it.

When i push my power button on my flatscreen monitor, the power light will turn green then blink off for 2 secnds then blink on

Could you please explain more about your problem. Are you able to get your monitor working or is it that it keeps on blinking without any display on screen.

If your CPU is ON and then your facing no display on the monitor then the problem could not be with the monitor instead it could be either a loose RAM. Also check that the cables attached to the CPU is not loose.

Dell flat screen started flashing, green light was blinking then screen went blank and green light is on. Tried unplugging etc...time for a new one?

No. It is not a Flat Screen issue. It is a CPU issue. You CPU is not sending signal to your flat screen so the green light is flashing. Try to:

1. Reset OR
2. Unplug the CPU case, Open the CPU, the interchange the RAM modules, OR
3. Same with step 2 but unplug and then plug back in all expansion cards like audio, video cards, etc.

It seems that your system needs discharging from a frozen state.
