Monitor won't go on blue power lite won't change to orange. don't know if its video card or monitor

Here's some tricks I would try...
1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or orange or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your display on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.

Good luck.

It sounds like the lamp for your monitor is no longer receiving power. While you can attempt to fix this issue yourself I wouldn't recommend doing so as it doesn't mean it will work after you attempt it.
If the monitor is under warranty still then you should contact the manufacturer about a RMA. If the monitor isn't under warranty then you should purchase a new monitor.

A component inside the monitor has failed - hardware failure, the monitor will have to be opened and tested to identify it.
The fact that the light appears on the screen shows the fact that the power source and the inverter are functioning - the failure is located in the mainboard. Because the status light doesn't changes color it means that the processor of the monitor is no longer loading the firmware - the damage is too great to be repaired. The board will have to be replaced and that will be expensive: $110 for a new board + the shipping to your location. If you don't have at least a basic experience in repairing electronics a visit to repair shop will cost you another $100.
In my opinion this monitor is not worth this much money: for $200 you can buy a bigger and better new one.

Hi there!
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.

Simple stuff first - power and connections to monitor good? Anything at all displayed as the machine is switched on? Yes: can you access safe mode (F8 when windows starts), if so enter windows and right click on desktop and choose properties, change display resolution to 1024x768 for example. No:
Any work inside the machine you should disconnect power first and preferable earth yourself when you are touching the boards.
Video card (where the monitor is connected) is seated correctly. Take out and put back in.
Try another monitor and cable to ensure these are working.
Check you have the 12v cable connected to the motherboard from the PSU. It is an additional cable that is required on some motherboards and can prevent display.
Does the motherboard make any beeps? Just one is good, more is not.
If you only get one beep and you have checked all above, then maybe a problem with video card - is it a separate card - see inside in slots where your monitor cables are plugged in. Could be loose, need reseating.
Best of luck

Could be an issue with the cable or the video card on your PC. However, first try switching the mode of the monitor. If your using DVI sometimes you need to change the monitor to DVI and the same for VGA. On the front of the monitor there are buttons that will do this switching.

Usually this problem happens when the video card is sending a signal to the monitor that the monitor does not recognize. (Kind of like me telling you how to fix this problem in a language I dreamed up myself.) The monitor will work on a different computer, because that computer has a video card "talking" to the monitor in a language it understands. So the solution is a different monitor that has a resolution setting your computer can talk to. Possibly you can borrow one, change the resolution of the card, and put your own back in. You can plug in and unplug monitors while the computer is on with no problem, to test.

ou have a problem with your video card, take a look if is correctly connected and turn off the computer.

try to use your BIOS to reset it to the factory settings

First when you power up the computer press F8 key then enter in enable vga mode.
If you are able to enter then go to start menu->control panel->display property ->settings.
Change screen resolution to 1024*768 then apply and ok.
But if you are not able to see safe mode and other menu.
Then open cpu cabinet .
Refix RAM memory.
Pull cmos cell from motherboard for 10 minutes.
Reattach all connection harddrive.
Open processor fan and processor remove dust from all parts.
Make sure motherboard is not ground with cabinet.
Remove PCI cards if any.
After all above still same then change RAM then try.
Let me know if you need further assistance.
Thanks for using FixYa.

Try re-seating the video Card.If no go.You will have to replace the video card.
