MFC-8710DW has no power

If your Brother machine does not appear to have power,then check whether or not the date and time appear on your Brother machine's LCD. If anything is displayed on your Brother machine's LCD, then it is most likely receiving power.If your Brother machine's LCD is blank, continue to Step 2.
Verify the Brother machine's power cord is connected securely to the power outlet. If you are using a surge protector, extension cord, or power switch, disconnect it and plug the Brother machine directly into the wall outlet.
Please note Brother strongly recommends that you connect your machine to a surge protector.Because To protect your investment against power surges and lightning,
In particular, we suggest that you use a surge protector that is compatible with both standard A.C. power cords and telephone line cords. Surge protectors equipped with telephone jacks will assist in insulating your machine from any power surge that might travel through a telephone line.
If the Brother machine is turned OFF, its LCD will be blank. Please make sure the Brother machine is powered ON by pressing and holding the On/Off or Power Save key. This key is located in the upper-right corner of the control panel.
If your Brother machine's LCD is still blank, connect it to a completely different, known working power outlet. If the Brother machine powers up, then the problem is related to the original outlet.
Confirm the power outlet is working by plugging another known working device (a lamp, radio, etc.) directly into the same outlet. If the other device does not work, the problem is related to that power outlet. If a wall switch controls the outlet, verify that the switch is ON.
If your Brother machine still will not power on, please contact Brother Customer Service.

Lexmark E450dn will not power on, power cord is working

This issue may be due to one of the following:

  • An incorrectly set power switch.
  • An improperly functioning power outlet, surge protector, or power supply backup.
  • A poorly connected power or data cable.
  • A defect with a third-party (i.e. non-Lexmark) option such as a memory card.
  • An incorrectly connected or malfunctioning optional paper tray.
  • A malfunctioning printer component.
Please try the following steps:

Step Action 1 Make sure the power switch is in the "on" position. If it is, power off the printer. 2 If your printer's power cord is plugged into a surge protector or uninterruptible power supply (UPS), unplug it and connect it directly to a grounded wall outlet. Some of these devices can interfere with consistent electrical flow and cause the printer to fail to power up properly. 3 Disconnect the power cord from the back of the machine and then reconnect it. Make sure the power cord is plugged in all the way. 4 Disconnect any data cables (parallel, USB, Ethernet) from the rear of the printer. Any defect in a data cable may cause an electrical short circuit that could cause a loss of power to the printer. 5 Turn the printer on, this time with only the power cord connected and plugged directly into a grounded wall outlet. 6 If the printer still fails to power up, power off the printer once more. Verify that the outlet is working properly by connecting another device to it to see if it receives power. You can also try plugging the printer into a different grounded outlet. 7 If possible, try another printer power cord. 8
Verify that the printer is the correct voltage type for the environment in which it is being used. A 110V (low-voltage) printer will not work properly in a 220V (high-voltage) environment, and vice versa.

  • NOTE: Look at the rear of the printer and locate the electrical specifications sticker. Verify that the voltage rating on the sticker is the correct voltage for your printing environment (i.e. 110V or 220V).
Remove any third-party (i.e. non-Lexmark) options, such as memory cards, as they may interfere with proper printer functioning. Also remove any paper-handling options such as an optional second paper tray. 10
Attempt to power on the printer once more with all options removed, having verified that other devices work from that power outlet.
If there is still no power, the printer may require service to fix the issue. Please contact Lexmark Technical Support or a local service provider.

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.
