Question about Dell E172FP 17" LCD Flat Panel Monitor
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!

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.

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.

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

I have had temporary success restarting windows... then I get display again--for me it typically happens during a restart.

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!!!

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.

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.

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.
