20 Most Recent Dell E172FP 17" LCD Flat Panel Monitor - Page 6 Questions & Answers

If you want to fix it, then you will need to buy some tools and basic knowledge of electronics, common problem with this monitor is the failed transistors and fuse in the inverter circuits, see pictures here as a guide: http://s807.photobucket.com/home/budm/allalbums
I would give the monitor to someone that is learning electronics to practice troubleshooting.

That monitor does not have speakers included. You will need to get a set of stereo speaker for your computer.

Hi
i am a Dell Certified System Certified(DCSE)

CLICK ON THE MENU BUTTON ON YOUR MONITOR
there are 4 buttons
first one from left is the menu button
use the - and + button move down to factory reset and press the menu button again
your monitor will be reset to factory defaults

Look for bad fuse and transistors in the inverter circuits, see picture of failed Dell monitors here: http://s807.photobucket.com/home/budm/allalbums

You need to open it up to inspect the inverter fuse and the transistors in the Power/Inverter board, see pictures here: http://s807.photobucket.com/home/budm/allalbums

G'day Dave
Have you tried the monitor on another computer?
If it exhibits the same problem on the other computer then you will need a new monitor. Then try a friends monitor on your computer.
If you want to be really sure about the state of your monitor, and if the lead between the monitor and the computer is removeable (some monitors have hard-wired leads which plug into the graphics port on the back of your computer) try replacing that lead with another lead. (borrow a friends monitor lead?) LCD monitors are very cheap these days and the cost of repairs to your monitor can be prohibitive taking into account the cost of a new monitor.
If your monitor (and connecting cable) is fine on another computer, you may have an issue with the graphics card inside your computer, which is inserted into a dedicated slot on the motherboard. Depending on your computers motherboard, it may not have a separate graphics card inserted into the motherboard, and the graphics may in fact originate from a dedicated graphics chip soldered onboard the motherboard. In that case (ie you have a dedicated chip) you may have to replace the motherboard. Dont forget to check all cables before deciding on purchasing anything new.
if you are not comfortable doing what I have described, use a computer geek friend or spend some some cash and have a reputable computer shop have a look at the problem.

You have inadvertently locked the On Screen Display (OSD).

To unlock do the following:

Press the menu button, which will take you directly to the OSD settings menu, and you will see 'OSD Lock' is selected. Change the seeting to No(-) to unlock and allow user access to all applicable settings.

You may have bad fuse, shorted out transistors (c5706/5707), please look here for Dell E series circuits boards: http://s807.photobucket.com/home/budm/allalbums

check for any magnetic fields if not check the power cable for any voltage fluctuation..or else you may need to change the monitor...

Disconnect the display from the Computer and remove its power plug. While the display is turned off, press and hold the power button for 30 seconds. After two minutes connect the power cord and the display cord to the Computer and the power source and turn it ON.

If the power indicator on the display keeps blinking, then it's required to open it up to repair it.

You will have to check the power supply for bad fuse connection.
Check for bad fuse and shorted (Emitter to Collector) transistors C5706/5707.

More likely to have problem in the inverter circuits, check for short between Emitter and Collector pin of the four transistors as shown in the pictures.

Native/max resolution for this Dell is 1280x1024, try this setting.

i can't tell you where to get the parts but i can help with the soldering information.

use 60/40 resin core solder
a 20 watt iron
to prevent over heating, you can try a desoldering iron or a special blower desolder gun. you can try adding extra solder to the part before trying to use a desoldering iron, this will help the desoldering iron **** out the old solder easier.

Look for shorted out transistors in the inverter transformers driving circuits, see example here: E172/173FP, http://s807.photobucket.com/home/budm/allalbums

You need to download the latest graphices drivers and get the update for the BIOS.
If the screen flickers in the BIOS screen as well that means the sys has to be repaired for the screen.

Try starting your computer in safe mode ( tap F8 while it boots up). If this works then you have probably got it set to the wrong resolution. Set it to the correct resolution (google the name of your monitor to find it's maximum resolution, or just set it to something low like 800x600 or 1024x768) by right-clicking on an empty bit of desktop and selecting the video settings or control panel for your video card.

If this does not work and you have checked your cables and your video card, then I would suggest you have a faulty monitor.

Hi,
Rt. click on desktop / properties / screen saver tab / power tab / turn off monitor dropdown...set to never /apply/ ok.

Try another monitor on your ATI 128MB VGA card if it is the same, take the card out, clean the contacts with a rubber / eraser & reinsert or try another card.
If it is OK, check your Power settings as well.

This could realted to power distribution on the board as well. Turn off and unplug your computer, take each card (PCI, AGP, PCI Express, Etc.) and reseat them. This can clear the issue most of the time, if not you might have a conflict between hardware devices, repeat the process, removing the cards again, but this time go it one at a time with a "boot" in between to narrow down the issue. The most common I have seen is with the desktops that have a wireless card installed with an antenna in the reart of the machine, over time, friction and movment and jar the card out of the slot on the board and kill your video and other devices until it is put back in place.

2 things cause that. 1 bad screen. 2 bad video driver. either way you need to replace parts.
