Question about Dell E172FP 17" LCD Flat Panel Monitor

10 Answers

Blank screen Screen is blank, power light is blinking green. Disconnecting the video connection makes no difference. A substitute monitor works OK, so definitely seems to be a monitor problem. Any ideas? Many thanks.

    Thanks Frazz. I fear you are right, but am going to try a local repairer. Mine IS out of warranty!

  • David Gilson May 20, 2006

    Thanks again Frazz. Unfortunately, the repairer decided he couldn't fix it. Dell had promised to give me a quote for a repair, but this didn't appear. So I've been shopping around for a replacement. It's tempting to go for an extended guarantee after this experience, but you can get a good replacement now for less than £150, and when the year's guarantee is up they will probably be less than £100, so I will continue to take my chances!

    my screen is blank but the power light is blinking what do i do

  • Anonymous Dec 01, 2007

    When I power on the monitor with or without the computer, the monitor powers up momentarily and then the screen goes dark black. The green power light stays on solid, but the screen is off. If I power cycle the monitor about10 to 15 times eventually the screen powers on. Then I get the no signal found box and when the computer is powered on the screen follows the boot up info. I have to power cycle the monitor with or without the computer turned on. It must not be the video card. But is this just the monitor wearing out? This happens with the VGA or DVI input connected.

    When I turn the monitor on, the screen pops up momentarily (about 2 sec) & then goes completely blank. The power is still on, but there is no image. What do I do

    DCL 9A+, I need a Schematic (blue print) of this board that is inside, mounted on the metal plate behind the monitor it self. My problem is that two of my components has been fry off, causing my monitor not to turn on. But the monitor still has power, with the green light blinky constantly. Those two components are R88 & C65, if any knows the value (voltage) of these two componets, I can fix it myself. If anyone has any spare parts and willing to help, I'll appreciate it very much.

  • bates6376 Dec 27, 2007

    I have had my monitor for a few years and all of a sudden, I get a BLANK screen. The green light is on, but no one is at home. I can see an image for about a second and then nothing. If I cut the power on and off, I see an image for a second then gone again. What is wrong with my monitor? Repair or replace??

  • texdig Jan 19, 2008

    Samsung 740 T now blank despite power light on. (When it WAS working, the screen remained partially lit and would not turn off from front button). The following site mentions noticeably blown or 'out of value' components on monitors ...which has helped me grow some balls. Will now remove cover and check 'r out. Many times, with the most complex equipment, you get lucky with something silly easy (like a fuse or noticeably blown or blackened component or connection)



    http://www.e-repair.co.uk/tipsmon.htm



    So don't just THROW AWAY an expensive item without even looking inside. Also, an honest technician can then take a quick look over without a dismantling charge. He'll likely throw up his hands and say it's not worth going further or say "the problem's likely to be ..." or "THERE'S the problem" !

  • MG55559 Feb 07, 2008

    My Monitor has been slow to turn on. When I start up my computer, it seems that the computer loads up, but the screen will not come on for about 20-30 minutes. The green light comes on for about 5 seconds and then blinks off and then comes on again. It repeats this until finally it will come on and then I have no problems for the rest of the time I am using it. I have unplugged it and that does not seem to work. I was unsure if I should try to update the drivers or reinstall the whole program.

    Mine is also blank. Power LED works. Other monitor works with
    same computer. Owner's manual says that in this case, "Using OSD,
    adjust Brightness and Contrast to maximum or reset totheir default
    settings."

    Are they kidding?? How do you adjust or reset anything if there's nothing on the screen?



  • Guy Cassegrain Jul 22, 2008

    Mine is a Daewoo F205 15 in. Flat Panel LCD. I bought it in '03. It
    also had a blank screen though the green LED was on. I took someone's
    hint and unplugged it. Now I've replugged it and it's been going for 15
    minutes and counting... Looks like the old re-initialisation trick came
    to the rescue once again.

This problem is very often caused by dry electrolytic capacitors on the inverter board. If you have some skill with soldering you could try to change them. When buying new ones ask for LOW-ESR capacitors for switching mode power supplies (SMPS) and 105°C, they are a little bit more expensive than normal electrolytic capacitors, but are designed for this aplications so they lasts more. Normal el. caps will also works fine so when you cannot buy LOW-ESR for SMPS use normal ones.

The problem could be the power supply as it was for my brother in law's monitor with this issue. The power supply read 12VDC when checked with a voltmeter, but when connected to the monitor. was loading down and cycling causing the flashing green power light on the monitor. You can check the power supply by connecting a 12 volt car parking light bulb to give the power supply a load, The power supply green light extinguished and failed to light the 12 volt car bulb when connected. The power supply is rated at 12 volts at 4 amps and another power supply rated 12 volts at 2 amps would power the light bulb and monitor when connected. Hope this helps and have a great day!

  • lennieseay Nov 24, 2009

    Solution number 5 was just to verify the original AC adapter power supply was the cause, by substituting a power supply rated at 12 volts at 2 amps. DO NOT use a power supply rated less than 12 volts at 4 amps for regular use as it will overheat. I did not want someone thinking they could buy or power the monitor with a lower rated power supply.

Just a tipp.
I have also a 447XS 17" monitor. I have the same problem (the monitor works a lot and then the picture goes away, but the power led is on).
The problem is the poor soldering (broken soldering points) at the high voltage transformer legs. Just a little soldering and the monitor works great again.
Warning! Be cautious at soldering! The components contains high voltage also at deactivated state!!!

Sorry for the bad english.

Bad inverter

Posted on Apr 22, 2008

Hey, guys, my power surged and my monitor power button flashes green and the screen is blank. When plugged in, I listen into the back, I hear  click and a beep with every flash. I'm just saying, if you guys hear this, it's definately a problem in the monitor and not in the computer, because mine works well with an older monitor. The power source probably died inside, meh.

Posted on Jan 09, 2008

It's easy to fix. Replace the power supply board or more commonly called inverter board. I fixed mine, it's easy.

    That's a pity that you couldn't get it repaired. My replacement from Dell arived the next day and we're up and running again. I must admit that I'm usually pretty sceptical about extended warranties, but the deal from Dell was far cheaper than anywhere else when we got the system (and still is). We've now got three Dell systems in the house all with extended warranties as it only adds about £60 to the cost of the systems for next day on site service and peace of mind for an extra 2 years. Dell customer service tends to get some bad press, but I've found them pretty good so far. Hope you find a good replacement.

An extended warrantee is not a bad idea except when they try to sell you differant types of extended warrantee such as a picture tube warrantees not a bad deal as most tvs already have a 2 year warrantee so really your only getting an extra 3 years so idf if the cost is reasonable lets say like under 50 bucks then what the hay i would go for it and lets say like on a refridge or freezer where they extend the warrantee to 5 years Where really most manufacturers alreadsy give ya 5 years on the sealed system but that takes care of labor but an extended warrantee like this will cost about 200 bucks so that woukld be the labor cost if it needed a major repair. Butt some folks are givin ya a rebate now if you take out an extended warrantee and dont use it as my warrantee I got for my fridge is 159.00bucks and if I dont use it in 5 years i get back 85.00 bucks!! So it really depense on how much they charge for the warrantee like if I lived in a remote area I would get an extended warrantee on almost everything I bought. So next time your offered and you say is it worth it?? Spead those paymennts out in your head and just say to yourself thats ids less expensive to pay a little across a time frame then alot all at once!!!

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.

SOURCE: my dell 2005fpw screen has gone blank and power

A flashing green is usually a power supply failure on the main board of the LCD and a protective shut down circuit kicks in when the voltages are not correct at the check sum.
This also depending on the circuit configuration that the monitor is in standby mode. Your user manual can give you this information.
This also may be the video card itself or a loose cable.
Check the monitor cable to see if it is secured.
Also check you resolution settings on the PC. This procedure will require you to connect another monitor to the pc to see if it will bring a signal.
If a signal is visible then the video card is ok.
If not then you will have to check the video driver for the video graphic display card and or replace the card.

Green light blinking screen blank


Hi Suzee,

Is the green flashing on the tower or the monitor?

If it is flashing on the monitor, then it might be tht the monitor is not gettign signal from the tower.
To check, disconnect the monitor from the tower and check the monitor. If you get a msg on the screen like no input signal or check video cable, then 99% monitor is fine.

Check for the power supply light at the back of the tower.

Disconnect everything from the computer and then press and hold the power button on the comp for about 30 seconds.

Then connect the cables and check if it is working.

Monitor started to flicker then went blank


I have a envision professional series and I love it, but I will get to the point.
I recent ly received a Envision EN9410e monitor, had the same problem (flickering screen then turned on, then off then on then blank). The problem is bad capacitors. There are 7 electrolytic capXon capacitors that will need to be replaced. You should see if the caps are bulging or leaking, if so replace. As known by many replace with the same capacitance and voltage. There are a few incidences that the capacitors where replaced and the problem wasn’t solved; this is because the cap problem wasn’t taken care of and damage occurred to another part of the monitor. The back light is a Royer oscillator (cool things) and it uses two smd mosfet transistors. They are on the green side of the circuit board near a big control chip (they each look like a off rectangle black square with eight pins) you need to see if there is any carbon or chard residue between the pins or burning smell from them, if there is you need to remove the transistor and do some board repair then ether put a new transistor or try the old one. No offence to the people at Envision but not smart putting the drain, gate and source so close to each other under the chip where there is such high voltage! Hope this helps.
