It blinks when it does not receive any "signal" from your computer's video-card.
Check that the video-cable is connected.
Try a different monitor, to see if the video-card is the problem.
Try the monitor on a different computer, to see if the monitor is OK.

The Green wire is a reverse trigger wire. It should be tied into the reverse light hot wire. This tells the monitor to turn on and switch to Video 2 so that it displays what is seen by the backup camera. When you take the vehicle out of reverse thus removing power from the green wire, the monitor switches back to normal driving mode. ( no video displayed ).

Did you check the service manual troubleshooting guide yet. You can try disconnecting the power to the inverter board and see if it will stay on and have sound.

I have a 19" cmv


How old is it? If it still under warranty get it repaired, it sounds like the switch is gone or the energy saving s/w inside is bad and is not detecting when/when not to turn the display on/off.

Most probably your monitor has two inputs, one digital and one analog. Using the monitor's on screen menu select the other input and you should see your picture.

I have exactly same problem


Sound like your display is having issues with the inverter board. When the power supply detects a short circuit, it turn off by itself. When you try several times, you may be able to "bypass" the circuit protection but the damaged parts still having problems. This issue may be related with the DELL display issues.

The display needs to be fixed by someone with experience in electronics repair.

Monitor Not Showing A Picture. Light flashes Yellow and Green.


use the onboard graphics instead of a seperate graphics card (if installed) to test the screen.if it still doesn't work then unplug your monitor from the mains supply and plug in again to reset it. i doubt it's your monitor that is the problem though. but look on the back of your pc for another connection for your screen. the onboard graphics connection is normally vertical near your ethernet port and mouse and keyboard inputs.

please rate me and give me a fixya! if it helped.

cmv221d wont power on even after changing capacitors Not even the LED or any response from the screen, nothing.. I ordered replacement capacitors, all except the big 400v one, replaced them all.. nothing's changed. I've ordered the big capacitor's replacement just incase, but heard they rarely break.. any other ideas of what the problem might be? The guy who gave me it said that he thought all that was wrong with it was a line across the screen (corresponding to where he said that line was, I found some dirt on the edge of the connectors). It actually did not power on as it was supposed to, according to the previous owner, who made no profit by giving it to me. A tiny part of the circuit-board did get slightly peeled when pushing one capacitor in, but only about 3mm across, affecting two small strips of whatever those little chrome strips are, but I soldered it back down.. I may have also re-attached the large Capacitor, and in folding it back down, had to force it.. could this have internally damaged it easily? This is the first time I've done anything like this, but I have followed a tutorial and learned the correct technique for soldering. Does anyone have any ideas what else it could be? The fuse looks fine. The power cable works in other monitors. I hear a little crackling if slowly pulling out the power cable as you'd expect with any screen if you listen close (atleast in Australia, I remember being surprised at how much things crackle here after moving from the UK). But yeah, basically the screen is stone cold dead, no response whatsoever..
