Question about LG Studioworks 700S 17" CRT Monitor
When i on my Computer, monitor is on but, there is no display on screen
You can try to remove the video card and transfer the vga cable to the on-board vga connector of the motherboard. If there's a display, your video card might have a problem. You can try to install a driver of the video card as a last resort and see if it solves the problem. If not get a new video card.

Chances are that this is a video card problem not the monitor.
If you have a plug in card, try reseating it, if the video is onboard, go buy either a PCI or AGP video card if your motherboard supports AGP.
Is the light on the monitor blinking or solid?

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:
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.
