If you are experiencing the problem of it cycling between the amber "NU" logo and then another screen such as the desktop and then back to the "NU" logo you have a defective internal power supply and need to have it fixed under warranty. Allot of these NUs are show up with this problem.

I also have a Nu L921G monitor that is having the exact same problem (screen cycles between the orange Nu logo and the screen its supposed to be displaying). I can actually hear a faint noise (sounds like static discharge) each time the monitor cycles. Of course, my warranty expired 3 months ago! I tried contacting Nu to see what a repair would cost - no luck, these guys are impossible to contact. They don't reply to emails and nobody answers the phone. They also have a horrible online registration process with poorly worded instructions.

If anybody knows of a way to get through to Nu, please post. I will never buy from a 2nd-tier company like Nu again. Before considering any vendor, check out their online support site to see how difficult it is to use before making a decision.

    Just got a call from a rep at Nu. He was very polite and apologetic and told me the repair would cost $20 for a new power supply board, $30 for labor, and round-trip UPS shipping. That puts the repair price at roughly 50% of a new monitor (with a larger screen).


    Given that power supplies are one of the most common failure mechanisms in consumer electronics, the lesson learned is to buy your next LCD monitor with an external power brick (although they can be a hassle if you don't have much room).

Hi there,
my L921G had same problem. The root cause was 3 defective capacitors (470uF/25V) in the power supply - you can tell it by a swelled top (prone to eventually burst). Capacitors replaced, and monitor works.
Tools required: Philips screw drivers #1 and #2, and solder iron.
Parts required: 3 capacitors 470-680uF / 25V (switch mode quality recommended).
The operations is quite simple and is completed within 1 hour or so.
Good luck and best regards

How to fi a phillips 20fp shuts off in 2 scs.


Here's some tricks I would try...
1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or orange or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your monitor on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.
Good luck.

Dell e137fp monitor flashing green...


Below you will find my recommendations for troubleshooting this issue:

1. Reseat the power cord and verify a good power source.

To reseat the power cord, follow the steps below:

1.1 Power down the system.
1.2 Unplug the power cord.
1.3 Wait approximately one minute.
1.4 Reseat the power cord.
1.5 Verify that the power cord is plugged directly into a known good power outlet.

2. Verify that the monitor is receiving power from a known good outlet and bypass any power strips.

To test the power outlet, perform the following steps:

2.1 Unplug the monitor power cable from the power outlet.
2.2 Plug in a different device, and verify that the device is operational.
2.3 If there is no power try another outlet. Remove any power strips and try plugging directly into the main power outlet.

3. Verify the monitor is powered on and the power button is engaged.

Ensure that the monitor is powered on and that the power button is fully engaged. To do so, check the power LED on the front of the monitor; it should be lit.

NOTE: There are two types of power switches:
A mechanical switch characterized by a long travel. You have to push it further and you will hear an audible click.
An electrical switch that has a short travel and almost no click.

A lit monitor LED can be any of the following:

* Green
* Blinking green
* Yellow
* Blinking yellow
* A combination, such as alternating green and yellow

Any of these states indicate the monitor is receiving power and that you should proceed.

4. Swap power cables.

To try a known good power cable on the monitor, follow the instructions below:

4.1 Turn off a working monitor.
4.2 Unplug the cable from the back of the working monitor, and unplug the cable from the wall.
4.3 Unplug the cable from the monitor in question.
4.4 Plug in the cable that came from the working monitor.

5. Run the monitor self test.

To run the monitor self test, perform the following steps:

5.1 Power off both the computer and the monitor.
5.2 Unplug the video cable from the computer or video card.
5.3 Reseat the power cord to the monitor, ensuring it is plugged into a known-good outlet.
5.4 Power on the monitor.

NOTE: The monitor self test will move around on some monitor models. If the monitor self test moves, allow it to move to the affected areas of the monitor to check for the problem described.

If the Self test failed, it's possible that the monitor is faulty. Contact dell to check if it's still under warranty so they can replace it.

Sounds as though the power cord reset switch might be bad and need to be replaced. If not, then there is a short somewhere in the system. Do an ohms test on the switch to determine if it is bad.
