Question about Dell E172FP 17" LCD Flat Panel Monitor

3 Answers

Dell Monitor goes blank, green light still on.

My 3 year old Dell monitor goes blank after the computer has been on for awhile. The green light is still on. Moving the mouse, clicking enter, tapping the space-bar do not make the screen come back. Sometimes if I power off the whole computer and turn it back on, the screen will come back. Uninstalled and re-installed the video drivers, replaced the cord between the monitor and tower.... now what? Hopefull I'll get an answer before the screen goes black again!!! Eeek!

    I have the same exact problem...I replaced the 15" Monitor for $129.00 at staples for a nice 17" Monitor.



    I think the problem comes from leaving the Dell monitor powered on for extended periods of time and like everything else in the universe it wears out with time ..after all 3 years 24/7 is quite a bash on anything.

Try one thing this will tell you if there is a problem with the monitor or the system
start the system and go in to bios and than check out if u still loose display
and if yes than when u loose display disconnect the data cable of the monitor from the system and chk out if u see the self test on the monitor or not
the self test if the colour patern if u see that its nothing wrong with the monitor its ur system
if u do not see the colour patern ... monitor bad
if the colour patern is seen reseat the cpu heatsink , remove the display card (if any add on display card ) and reseat the memory cards
and if that doesnt work remove all the add on cards and than start the system on the onboard display
and than put the cards one by one u will get the culprit

Have you tried connecting that monitor to another PC. It sounds like you may have a problem with the monitor itself (component failure, heat problem, etc)

Dell monitor shows blank screen, green power light stays on


Hello,

You have a monitor with a common problem. After a few years some LCD monitorswill blow a power supply. The problem is caused by parts calledcapacitors overheating in the confined space of he monitor. If you aregood at electronics repair/soldering you can usually fix he problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htmYou can take the back cover off your monitor and look for the bad parts,replace any that look like the pictues and your monitor should workfine. The capacitors do need to be installed with the correct + and -connections, note the stripe on the old one and insert the new one thesame way. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping. I hope this helps, if so please rate my solution.

My monitor screen goes black


The monitor is going bad. Either going to be a bad screen or a bad inverter. Also Since you tried it on another computer and its still giving you the same symptoms, you know the computers are fine. To be sure, try another monitor on your computer and if you get video on the new monitor then thats another way of verifying that the dell monitor is bad.

Please disconnect the Monitor Data cable from Computer.
If you see Dell Colored bars, it means, monitor is working fine,
If still black, please ask for replacement, since Monitors have 3 years of warranty if not purchased with the computer.

Now connect the cable back to computer and turn the computer off by holding the power button on computer and turn it back on...

Monitor won't turn on without help.


Do you have a second monitor or can you borrow one to check if the fault lies with the monitor or the PC?

If the monitor is at fault then there is not much you can do yourself. I suggest you contact Dell and get them to replace it under warranty. Most LCD monitors have a 3 year warrantly, at least they do in the UK.

cheers
