Question about Dell E172FP 17" LCD Flat Panel Monitor

2 Answers

My Dell Monitor on/off switch blinks green all of the time.

I have unplugged the monitor and waited a few minutes, but it continues to blink. Whether the computer is on or not, the monitor blinks. There is no picture on the screen--it is complete dark.
What is the problem?

You need to open the monitor and check to se eif any of the capacitors on the power board are bad. Common problem for LCD monitors. The bad caps usually vent at the top (they will look bad compaired to a good capacitor).

If they look bad then they will need to be replaced. I've seen this in Dell monitors, so there's a good chance this will fix the monitor.
Take it apart, get the values on the sides of the bad caps in the power supply pcb. Buy new caps, and de-solder the old ones and replace them with the new ones. Don't forget to trim the leads afterwords.

My Dell 1905FP LCD monitor Power light blink on startup


Hello,

This is a classic symptom of filter capacitor failure on the power supply board. The Dell 1905FP and 1907FP both use the same power supply and this type of failure is very common. You can repair the unit by replacing the filter capacitors on the power supply board. Here is a picture of the board with the problem capacitors circled and below is a link to a repair guide for this series monitor.

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.

Moniter won't turn on/power light blinks green


Yeah, I called Dell yesterday, and they said it was a problem that I could not fix myself. Whether that's true or not, I don't know, but my monitor was still under warranty, so they shipped me a replacement right away. I already got it this morning. 

FYI: Their monitors carry a three year warranty.

Monitor Went Black


It sounds like the monitor might be going bad. I would try hooking up another computer to it. If it works with another computer, then I would say the Video card might be going bad.

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.

17" veiwsonic power blinking green


The flashing green power button is a well known electronic problem with this (and other) Viewsonic LCD monitors. There is a YouTube video (do a search) showing how to disassemble the VX924 and find out whether the problem is related to blown capacitors. When I took my VX922 apart I discovered 6 bad capacitors out of a total of 7 on the power supply circuit board.Only recommended for those handy with a soldering iron.
