My LCD monitor suddenly decided to quit working. There is power at the AC adaptor (green light is on) but nothing happens when I push the power button on the monitor.

Any ideas?

    I swapped my monitor with one from a friends computer. It works fine on my computer, so my video card is OK. My monitor wouldn't work on his computer, either. The power/video cable is integral to the monitor, so I don't know if I could replace it. There are wires going from the power button to the small circuit boad on the side with 4 menu buttons. How could I test this to see if this board is the problem not allowing the power to continue to the monitor?

This could be one of three components:
1. The video card
2. Video Cable (cable from the monitor to the computer)
3. The Monitor

The way I would determine this is:

I would try to plug this monitor into another computer that you know works with other monitor. If this is a home computer and you don't have another computer to test this take it to a friends house. Use a different cable to connect the to computer and power if possible. Then switch out to the old hardware (e.g. power cable, video cable.) If all has been determined to work then it's probably the video card.

If you can do this at all I would suggest trying a new video cable they are cheap. Usually 10 bucks at the most or borrow on from someone else. If this is a DVI cable they are a little more expensive. VGA cables look like this btw

    In order to test this board you would need an digital ohm meter and the board specs to see if the correct wattage is coming into the board and going out. If you can't get a hold of the spec just check to see any power what so ever is flowing out of the board. You can also visually inspect the board to see if any thing has blown like a capacitor. This will usually smell like burnt popcorn when it happens. This link should help you identify blown capacitors since they are the main source for building the power to run the monitor itself.

The lamp on the power supply adapter should be on the minute it is plugged onto the AC outlet without the DC plug connected to the monitor, if it is not on then the AC adapter is bad, you can check the DC voltage with a digital meter. Post back so we can guide you further.

My Neovo E-W22 monitor quit working. I have had it just under 2 years. It is as if it is getting no power. Any ideas?

Make sure the power connector is secure with your monitor and the adapter power light is on as green. If not working at all then just contact with AG Neovo as for 3 yrs warranty repair. But you probably have to cover the one way shipping only.

I'd reseat the memory first. If there are two pieces, take first one, then the other alone in the system. Possibly bad memory. If that's not it, the lcd cable could be unplugged. Try connecting to an external monitor. If that works, it's the lcd somewhere.
Good luck

Monitor suddenly goes black

Is this monitor and LCD flat Panel? If so this is due to a bad power supply, an inverter board going bad or LCD backlight bulb blown. When the backlight goes bad it gets just enough power to start up, but when it is on for a long period of time it goes black because the bulb is not stable enough to hold the charge because it is going bad. These bulbs can be changed, but they also can be costly!
