I have a HP desktop monitor that is about 4 years old. It has worked fine but all of a sudden it doesn't work. When I power up the computer, the green light indicator comes on like normal but them it switches to the orange light and the screen stays black. I have disconnected it from the computer and the screen says "no signal". Is there anything I can do?

1. Please check the video port connection if properly plug-in it could be loosen 2. Please check if the power cord of the monitor is properly plug-in maybe it was accidentally disconnected from the power source.
3. Press the power button on the monitor ad check all the LED lights. 4. To isolate the issue we can use other monitor or we can try the monitor that is not working to other PC.Again,if the problem continues plase call the manufacturer or call the store where the item was purchase.
First I think you should do some troubleshooting. Try hooking up your computer to a different monitor and see if there's any display when you boot up. If that doesn't work, then open up the desktop and make sure all of the power connections are solid. One that sometimes comes off is the 2nd motherboard power connector. Because you aren't seeing the blue LED, I think it might be that connector. The motherboard has one 24 or 26 pin power connector and one simple 4 pin connector. The 4 pin is usually in a corner near the processor. Take a look at that to see if your motherboard is getting all of the power it needs. If everything is connected properly and your monitor isn't the problem, the new power supply you ordered could fix the problem. I hope this helps!
I strongly advise you to replace your old (VERY OLD!!) PC with new one. Do not worry, you will not lose any data from your old PC if you will take hard drive off your old PC and fix to new one.
Anyway, if you still want to keep your old PC (NOT RECOMMENDED) you will have to buy new Power Supply and clean up your PC inside.
I do not know exactly what is going on with your computer, but if the light by the power button comes on and stays on then you can try pulling the ram out of it and then put it back in.
A few years ago i had a compaq computer and all of a sudden it would not come on but the light by the power button was on. I thought the computer was shot but i contacted a tech and he told me to pull the ram out and put it back in. I did this and the computer came back to life and worked fine.
Good luck. I hope this works for you.
