Need a new power cord

Go to a computer store and ask them for an Ac power cord

It may have failed Backlight inverter circuits. You just need power AC cord and the VGA cable to attach to the PC VIDEO card. Try it on another PC.

There are times when you need to install software for a monitor to work with a PC. If you have the software disk that came with the monitor, you can try to install. You can also try changing the power cord to the monitor. Generally, power cords for PC's and monitors are the same. If you use your PC power cord and the monitor comes on saying that there is no connection with a computer, and it was not doing this before, you can get a new power cord for the monitor. If you can, try the monitor with another PC or laptop to rule out a bad monitor.
I hope these suggestions have given you a place to start and that they were helpful.

I have the same problem. I just unplug it and reconnect. The display comes back. I have no idea why this is happening.

You can use a power supply for a CCTV system. Here is a website that has one, it is for a DVR4220, code STD-1205

buy replacement ac power adapter for GO VIDEO GOVIDEO DP7240

THE POWER SUPPLY PLUGS INTO A WIRE STICKING OUT OF THE END THAT PLUGS INTO THE COMPUTER

You should be able to go to any local store like BestBuy and pick up a power cable. The monitor uses the same power cable as a Desktop PC.

Good luck!

i thin i best u not opening it up ur self just make sure that the fuse in the plug is still working and see if the light on the power pack is lit other than that its best gettin a proffesional to look at it hope this helps

I think what you need is a "D" shell connector.. see if the one that fits your PC Power Supply will fit into the Monitor.. if so then purchase another the same. It's called a "D Shell" Power Cord.
