Re: No display (black) - power light is amber color
The video signal is not reaching your monitor, check the pins on the connector from the monitor to the computer, then check the video card:
Turn off your computer, unplg the power, and then take out the video card. Wait 5 minutes and then put the card back into the computer and turn it on. For onboard video; turn off the computer, unplug the power, then hold down the power button on the front for 5-10 seconds, then plug back in and turn on.
Make sure the video card is snug in the AGP/PCI slot. If this is built-in video, try borrowing a video card from another computer and install it in this one. If the borrowed card works, then replace you card. If video is built in, then you can disble the onboard video and use the new card without having to replace your motherboard.

Hi, if the monitor light is blinking this suggests that, there is no display signal coming from the tower. This could be because of the following .
1. Bad video card 2. Bad video software
To check,where the problem is , power of the system tower and remove the power cord from the back of the tower. Press and hold the power buttoon for 10 seconds and the reconnect the power cord and turn the tower on. Check if there is any display or the status of the light changes from amber to green for even a small instance.
If the light changes to green and back to amber the video port on the tower is bad
Alternatively you can connect the monitor to another desktop or laptop to check if the same is working correctly.
tried with other monitor just to ensure if the problem is only with in the monitor. if the same problem, the cause it could be the inverter board for screen back light which has component being shorted.
Changing the monitor light from green to yellow/orange/amber means that the monitor is in power saving mode. Make sure that the video signal cable is properly connected to the back of the monitor as well as to the computer.
Hope this helps.
First--was it working? Did it suddenly stop? When you see the LG logo, then it goes away, does the power light turn from green to amber? Sounds like that doesn't happen. So--if you are getting a signal, you should see something. If there is no signal, then the power light should change from green to orange. With no lights at all, I suspect a faulty monitor.
If screen says "Signal cable not connected " all the time till power led switches to Amber chances are monitor is ok and problem is with graphic card or cpu.Connect to Known working CPU and confirm that monitor is the problem.
If same problem persists on another working cpu after changing signal cable,the interface board in the monitor could be defective.
I agree it isn?t the monitor but I would suspect the video card you are connecting it to or the PC itself. Generally if a monitor doesn?t detect a video signal it will go into hibernation mode, typically displaying a no signal warning and changing the LED color from green to amber.
When you start the computer is anything displaying at all? Are you sure the PC is powering up and booting?
It could also be because there is a problem with the display controller in the computer. Try to hook up another monitor to this computer and see if it comes up. If it does not work with another monitor, the computer will need servicing. If the display does come up, the Samsung monitor will need service. Good Luck
I'd try this monitor on a spare computer. It sounds like the video card (motherboard integrated or otherwise)is not putting out any video information or missing sync signals. The monitor must receive these signals or it will go into standy/sleep mode.
If the computer has integrated (on motherboard) video, check your bios settings to see if it is properly enabled. If it has a slot video board, then try a different video board. Your present board might be dead.
Another possibility is a bad cable connection. check the connectors for bent pins. Assuming the connector is the standard HDB-15, it is easy to bend a pin over.
