Connect the monitor to the VGA-output from any laptop/notebook computer, to see if it works at all. If not, then recycle it.

Usually when the power light flashes and the screen remains blank and unlit, your power board is in fact malfunctioning. This is not always the case, as the problem can sometimes reside in the input or inverter boards. I would first recommend that you feel comfortable with opening up your screen and looking at components. It can be a little overwhelming at first. BEFORE PROCEEDING, UNPLUG POWER TO MONITOR. If inclined to check, carefully open the casing around your screen. I have not worked on your particular model, but some are easier to open than others.

Once opened, you need to gain access to the circuit boards. Sometimes they are not protected by metal, other times they are completely encompassed. The flashing power light usually indicates that a capacitor(s) is(are) malfunctioning. To see if this is the issue, locate the power board (usually the one with larger-size components) and look for any capacitors having bubbled or raised tops and/or oozing a brownish liquid. If not on the power board, look elsewhere for the same symptom.

PLEASE BE CAREFUL!!! If you have recently had your monitor plugged in, the larger capacitors can still carry a charge. If you cross the leads of a capacitor while it carries a charge, it will discharge. It won't hurt any other components, but if you cross the leads with something that is in direct contact with yourself, you can get quite a jolt! There is usually a large voltage capacitor (normally just one) on the power board of these screens. I tested one with a multimeter after immediately unplugging it, and it still held a 166V charge! So please, do this with caution.

If a bad capacitor has been found, simply remove the old one and solder a new one in its place!

Hello,

You have a monitor with a common problem. After a few years some LCD monitorswill blow a power supply. The problem is caused by parts calledcapacitors overheating in the confined space of he monitor. If you aregood at electronics repair/soldering you can usually fix he problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htmYou can take the back cover off your monitor and look for the bad parts,replace any that look like the pictues and your monitor should workfine. The capacitors do need to be installed with the correct + and -connections, note the stripe on the old one and insert the new one thesame way. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping. I hope this helps, if so please rate my solution.

Find technicaiy solution


That means your monitor has faulty or dead capacitors. The capacitors in your monitor work to hold down power from the source long enough for proper display on the screen. Bulged or leaking capacitors will only hold power for about 2 - 8 seconds and the looses it. The only solution is to replace those fault capacitors with new ones. Get a computer technician to open up the monitor and change the capacitors. That is the only technical problem you asked to know. Good luck

You won't find that here and Dell may not even release service info to individuals; I had a business with monitor repair as one of my most frequent repairs - well, until the Chinese could make them cheaper than I could repair them. And, unless you have some training in electronics, a few pieces of needed test equipment, the service literature probably won't help you much. I repaired in excess of 2,000 monitors and had service literature on exactly three models.
If you care to describe the problem you are having, I can probably give you some tips although the first one I'll give you now; unique parts in that unit will not be available any more. Standard semi's are easy but the flyback and any programmable ICs may not have ever been available except to authorized Dell service centers.

Screen is distorted


hi there, Below the monitor, on the center are option button, you can explore that in adjusting your screen display. You can widen the display, or tweak it depending on the angle that you need to. Just press the center button and choose from the menu.

Hi, The part where you see some color bars and blinking green led is what we call MONITOR SELF TEST. A diagnostic pattern consisting of four colors (red, green, blue and white) appears, and the LED flashes slowly. this happens when signal cable from the monitor is disconnected from the tower and leaving the power chord for the monitor plugged in. If the monitor works properly on a different computer. then its a problem with the computer's video card sending out signal. im 85% sure that its a problem with your video card.

Problem with my Dell E771mm 17 in.CRT monitor


How far from the sides is the image? If it?s just an inch or two you can use the monitor adjustments to expand the image to the edge of the screen where it was previously. If its too far in then the only option is to have it repaired. You didn't mention where you are but in the US even a minor monitor repair that involves at tech opening the monitor is going to cost at least $45, perhaps more. That?s a lot of money for a monitor worth about $100 new so a new or used monitor may be a more cost effective option for you. Let us know if you have any other questions and please don't forget to rate this post.
