20 Most Recent Dell E173FPb 17" TFT LCD Monitor Questions & Answers

Your monitor provides a self-test feature that allows you to check whether your monitor is functioning properly. If your monitor and computer are properly connected but the monitor screen remains dark, run the monitor self-test by performing the following steps:

1. Turn off both your computer and monitor.
2. Unplug the video cable from the back of the computer. To ensure proper Self-Test operation, remove both Digital (white connector) and the Analog(blue connector) cables from the back of computer.
3. Turn on the monitor.

   The floating 'Dell Self-test Feature Check' dialog box should appear on-screen on a black background if the monitor cannot sense a video signal and is working correctly. While in self-test mode, the power LED remains green. Also, depending upon the selected input, one of the dialogs shown below will continuously scroll through the screen.

   1. This box also appears during normal system operation if the video cable becomes disconnected or damaged.

   2. Turn off your monitor and reconnect the video cable, then turn on both your computer and the monitor.

   If your monitor screen remains blank after you use the previous procedure, check your video controller and computer system; your monitor is functioning properly.

Hi there! You can test first if the monitor is working. Disconnect it from the computer then turn it on after that it should show you colors on the screen this means its working if not then its no use trying it on a different computer.


Hope this helps!

The possible reasons for this could be;

1.)A loose connection between either the graphics card and the computer mainboard or between the Graphics Card and the Computer Monitor.
2.)Your LCD monitor has become faulty and either needs to be repaired by a technician or replaced.
3.)Your graphics card need to be cleaned, clean the gold finger contact on the card.

However in my experience I would say that the monitor has become faulty, try this monitor on another computer and if it still displays vertical lines then you know that this is the case.

If your monitor works on another computer then I would say that your computer or Graphics card is having some troubles.
Overheating plays an important role here.

I assume you've tried turning the brightness up via the on screen menu, so it could be a blown capacitor(s) which is stopping enough power getting to the backlight, or a problem with the backlight itself. If it's under warranty then you could send it off to be fixed, although you may have to pay for it to be picked up/sent off etc.

If not then you could probably get a tv repairman to check it out, but it may cost a bit as well.

If it's blown capacitors then the cheapest option is to do it yourself or to a get a competent friend to do it. You just need to be comfortable using a soldering iron. Capacitors are pretty cheap and easy to replace.

If it's not blown caps, then it's likely to be a problem with the backlight which unfortunately I can't provide any advice about. But check for burn marks on the boards just in case it's something else.

I've had blown caps on a dell monitor, a 42" plasma tv and a 37" LED LCD tv, all now fixed and working properly.

They should look something like this:

As you should be able to see, the one on the left is bulging. The blue stripe with the arrow tells you that the lead on that side is the negative, the positive lead should also be longer than the negative one.

Tools needed
-----------------
1. Soldering iron.
2. Solder - not acid core
3. Phillips screwdriver
4. Flat head screwdriver
5. Wirecutters

Instructions
--------------

1. Unplug monitor and open case, you may need to use the flathead screwdriver to gently and carefully lever the case off in some cases.

2. Identify power board, it should have a lot of electrolytic caps on there and obviously should be connected to where the power lead is attached.

3. Identify the bad caps, they should be bulging and/or leaking, although not always. Note down the three values for each cap (eg 220uf, 16v, 105c) and their approximate dimensions, and get new ones, preferably Rubicon or Panasonic. If in doubt you could remove them and take them to the shop, but you'll have to remember where each one goes and which way round it was (take a pic).

4. Very carefully heat up the contacts on one side with the soldering iron, and rock the cap the other way, then do the other side, keep doing this until the cap comes out.

4. Replace with new cap, making sure that you observe the polarity and make sure it's securely seated and soldered in. Make sure the solder is neat, tidy and doesn't contact anything else. If there's any solder left in the holes then you'll have to heat it up or remove it before you can get the new cap's leads through. Once done properly trim the leads off so they won't cause any problems.

5. Replace casing and test. If it doesn't work then you'll have been a bit messy with the solder, tidy it up and try it again.

Or www.digikey.com, just make sure to use caps with low ESR, 105c, high ripple current and long life rating such as PANASONIC FM or FC series. Please post back what you find.

Check for shorted out transistors in the inverter circuits, also check the fuse, caps, solder joints.
You may want to buy the board if you do not want to troubleshoot it down to components level.

First, check all connections carefully.

Have you reinstalled the monitor using the disk that came with the system?
Try getting off the internet and turning off your virus control before installation. Also, make sure there are not a lot of programs running in the background. You can check what is running by right clicking on your desktop. You can unclick anything that has nothing to do with the system or windows, such as programs that you have installed etc. You can go back afterwards and recheck them, for immediate startup.

I hope this helps.

If you are going to DIY and have proper tools and know safety precaution then please read on: Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps).

1. If you have an Nvidia or ATI graphics card your video card is bad.
2. If you have integrated graphics (the video port is part of the motherboard), your RAM is bad.
3. Your computer is packed full of dust because you've never cleaned the GD thing and it's fking overheating.

Power light blinking? Try Plugging directly into the wall outlet istead of the UPS?
Otherwise you may have problem in the power/inverter board and need to do component level troubleshooting.
