Did the same and burnt a frazzled chip. it is on the 3rd circuit board (I believe it provides the lamp power). It is the 8 pin surface mount chip next to C900. As far as I can make out, the numbers on the chip are 4559 **** **7B I was told it's the lamp drive. If it is indeed lamp drive, then when you turn the monitor on, round the edges of a flashlight pressed to the screen, you should see a picture. If there isn't one, you may have killed more than I did. Is there no power regulator at the input? Good luck

SOURCE: Sir Help me with my Compaq monitor MV520 it won't turn the power led flashing orange to green continously

it could be th epower supply and it could be the monitor.
power ON button should not flash orange regardless what you do. it should stay green. then orange. not orange to green to orange.
try the monitor on another PC if you can fine one.
the other thing is are the 2 monitor similar (CRT to CRT and LCD to LCD), you can't mix the the two, they will work but need different video driver to function correctly.

SOURCE: problem with compaq MV 520 monitor

Your monitor is operating normally. After Windows starts it is setting the video resolution to something outside of the monitor's range. That's why you see the Windows splash screen, then the message from the monitor about the settings. Most likely the computer was used before with a monitor that had a wider range of resolutions available.

Restart the computer. When the manufacturer's logo screen appears, press the F8 key three or four times. This should get you a startup menu screen. Pick the option of starting in VGA mode, and Windows will start with video settings that your monitor supports.

The monitor will not turn on. When power button


First--was it working?
Did it suddenly stop?
When you see the LG logo, then it goes away, does the power light turn from green to amber? Sounds like that doesn't happen.
So--if you are getting a signal, you should see something.
If there is no signal, then the power light should change from green to orange.
With no lights at all, I suspect a faulty monitor.

Monitor will not stay on


Generally Monitors have a single light in fron pannel, with dual mode colors as Green and Orange.

Green: Everything is OK .
Orange: Everything is OK, except it is not getting
any signals from computer or other source.

Try with any other monitor with your CPU, it may happen that CPU actually not providing any signal to Monitor. Try checking the "NUM LOCK" button on and off, whether it makes the light on keyboard to flash on or off.
If NUM LOCK is woking OK, there is surely some problme with your monitor and you need to get is checked physically with an engineer.

Monitor stopped working...checked all connections...light won't stay on green. bought a new monitor to replace it and that monitor says "no signal". is this a problem with the dell computer and not the...


Your monitor is going into power saving mode. When it receives no video signal from the computer, it will stay powered for a few seconds before giving up and presuming the PC is off hence why it stays green for a while, then goes orange.

The problem is with your PC not the monitor(s)

The light turning to orange means the monitor is not getting a signal from the computer. Check your monitor cable at both ends and make sure it is in very tight and secure at the computer end as well. Also check to see if the computer stays on when the light goes to orange on the monitor. The power cord for the computer might be loose.

Dell Monitor won't stay on


When it goes black, does the power buton stay green or is it orange? If it's orange, the power supply/inverter is your main culprit. If the power button stays green, it sounds like the backlight for the display is bad. Either way, unless you have parts for the same monitor laying around to swap out, you're due for a new monitor. The good news- with the economy in the tank, you can search online and find some reputable vendors selling nicely sized screens for less than $100! Heck, I've even seen a 22" for $129 (once but it was there).
