Cyvlone monitor[cwm8000] power cord - Cyclone Car Audio & Video

I can't find information online about your monitor, so I'll give you a generic answer for all monitors.

Almost all monitors use a C13 cord - the same kind used for a desktop computer. Some use a C7 (two-wire, like that used for some name brand laptop adapters) or a C5 (three-wire, used on other laptop adapters)

These images were lifted from the Mouser Electronics website (AC Power Cords Mouser ). They also carry C13 cords with right-angled plugs, which may be more convenient with some monitors.

There are a very few monitors that use an external power supply, which is like a laptop computer power adapter. If this is the case, the voltage and current requirements for the power supply should be on the label on the back of the monitor, and the only other thing you have match is the plug on the power adapter output cord (it needs to fit the power jack on the back of the monitor). Note: the voltage of the power supply must be the same as that shown on the label (usually 12 VDC) and the current rating must be the same or higher. If you don't see the voltage and current listed on the label, look closely at the power jack - the numbers may be molded into the plastic next to it.

It is rare to find a monitor with a permanently attached power cord. If this is the case with yours and it is damaged, do not attempt to splice it outside of the monitor. Put a replacement plug on if the good part of the cord is long enough, and use a good extension cord. Otherwise, you should open up the case and replace the entire cord. You will probably have to get a connector for the part of the power cord inside the monitor also. (If you are good with soldering, you may be able to splice to this connector, using heat-shrink tubing to insulate the connections.)

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

I apologize for thinking so simply, however, your monitor has a separate power button and power cord. Therefore, even if you computer is off, there should be power to the monitor unless the monitor is not plugged in or the power button is turned off.

Check the power button and power cord for the monitor.

-usually the power cord for the monitor and the desktop computer is the same
-try connecting the power cord of your computer to your monitor and if it fits you can go to your local computer shop and buy a power cord for your desktop computer

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.

You cannot use a VGA cord to power a monitor. That is the cord that connects the monitor to the computer and is not the power cord. Almost all monitors use the exact same 3 prong power cord. Any computer shop will have a used one on hand.

The problem is either with the power cord itself (especially if it is connected to the monitor such that it stays bent all the time), or the problem might be with the socket into which the power cord plugs in the monitor. The solder joints fixing the power socket to the circuit board & connecting the power terminals to the circuitry usually tend to get loose after some period of usage either due to mechanical stress while connecting/disconnecting the power cord to/from the socket, or due to high currents passing through these joints continuously.
My suggestion is to test with a power cord which is known to work without problems. If this did not fix the problem, then the monitor will need service (monitor needs to be disassembled to a degree that permits re-soldering of the power socket's terminals to the circuit board).

that means the power cord is faulty, the monitor does no send message to the power cord rather the power cord sends message to the monitor so its the power cord that's bad expecially if its an adaptor, thanks

Monitors need power cords to function, & there is nowhere near enough power in the data cable to power the monitor. So, it sounds like the power cable got pulled out somehow and is now lying on the floor. The power cable will be a small plug like you have on a radio or other similar devices instead of the standard sized plug that older monitors have. Once you plug the power cord back in, it should be fine.

Good luck!

no cords for monitor, cords do i need
