Question about Dell E176FP 17" LCD Monitor

1 Answer

Different color test patterns keep cycling .

As soon as display is powered up, some sort of test patterns keep cycling and the buttons do not seem to have any effect except the power button. After about ten minutes, the pattern stops cycling and remains locked on a triple blue gradient pattern. At this point, even the power switch has no effect. The colors are radient so I don't believe it is a power supply problem. This occurs regardless of disconnecting from the computer.

    Dave, thanks for trying, but I actually tried that first. Dell says that with nothing hooked up, their logo should be displayed, and then a " No Video" message should show up. This unit goes into the test patterns even with good video applied.

This could be a computer or monitor problem. The reason that display shows up is because the monitor is not getting a power good signal from the computer. If a monitor doesn't get a power good signal it goes into test mode. It could be the monitor has a fault that is not allowing it to detect the computer, or the video card or computer itself isn't functioning properly. If you can, hook the monitor to a computer that you know is working properly. This will tell for sure if it is the monitor or not, and eliminate that possiblity. Then you will know if it is the monitor or computer. If the computer is the problem you'll need more help troubleshooting it.

    Yeah, I'd say it's definetly the monitor. There are some companys that do repairs on LCD's, but it's usually just as expensive than buying a new monitor, sometimes more expensive.

Not true color


I seem to have found the solution (and the cause, perhaps?) for this problem!

I was having the EXACT same problem with a monitor I'm repairing for a friend. The capacitors on the power supply board were blown (CapXon capacitors, who'd've guessed), which was keeping it from powering up. After replacing the capacitors, the screen worked beautifully. But it had this weird yellow tint!

The strange part was that pure colors - red, green, blue - all appeared perfectly OK on screen. Curiously, the menus would show in the proper colors, except for one: the manual color adjustment menu, which illustrated "Blue" as a sort of off-green in the icon. Auto-Adjust would always fix the colors for a split second, then go back to yellow. Reset didn't fix it. Color reset didn't either. So, exactly the same problem as above.

The solution I found was hidden within the main menu itself, a sort of "easter egg". <b>Hold the Menu button down while pressing Power, and hold it down until the screen, and menu, appear</b>. There will now be a hidden selection, "Auto Color", printed in a red-on-black font at the bottom of the menu. Use the +/- buttons to access it, and press Menu. Voila! PERFECT COLOR! Perhaps this menu was accessed by accident, and calibrated to an incorrect color key. But now my picture works great, and the setting lasts through Auto-Adjusts and Resets!

Colors in QL-711V shifted to green


Hi, I had the same problem and I wrote an email to Nu. They wrote me back that I should use the Factory reset feature which you have to go through the Factory Menu to get to. Instructions to do this are as follows. I got to the menu my first try but it has been a pain to get back to it. I hope it will be easier to access for yours.

Hope this helps

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.

Monitor revives only after cycling the power many times


Unscrew 4 screws on the back side. Place the monitor with the front up and open it along the upper seam. Turn it again and lift the back cover. Shift the inner case "up" and take the button holding plate out - it is being held only by a tape. Inspect it and clean it. You might have to replace the condensers and/or switches on it.

This might solve the problem, but there may be other causes as well.

Good luck!
