Blinking monitor power button and flashing image

I have a dell e172fp 17 inch . suddenly when I tried to wake it up from power saver mode, it flashed a second and went blank. it keeps blinking green light on the power button. the monitor blinks white once in a while. when i press the power button hard, it shows the screen once. Does anyone know what is the reason for this problem ?

    I have a Dell E152 FPb monitor that is doing the same thing. Works fine as long as it is stays on. If the computer goes into sleep or hibernation mode, the monitor will not come back on when I try to wake it up. Power light blinks (green, orange, off, green, orange, etc.) and then the screen blinks with dark lines and eventually goes off. Pressing the power button does not do anything. Only way I've gotten it to work again is to unplug the power cord in the back of monitor. Updated Video driver, but same problem happens again after hibernation or sleep mode. Any idea?

    Yes, I am having the exact same problem and can't afford to repair it. Any suggestions would help. My screen is just blinking out. It'll come on fine when I turn it on for 2 seconds then goes out again. Why is this a recurring problem. I have had the monitor since 2005.

I buy and sell these monitors (Dell E17FP) the problem is with the transisters (Q739, Q740, Q759, Q760) they short out and the monitor will just blink on and off. You have to desolder them and test them with a simple battery and light circuit. The reason they blow is because of the dirty solder joints by the transformers. If only on pair of backlights work the problem maybe transisters Q751, Q743. I home this answers your questions.

I bought the parts (6 transistors, 1 fuse) on ebay (http://cgi.ebay.com/DELL-REPAIR-KIT-E152FP-E153FP-E172FP-E173FP-E173FPB-/220488756040) and put them in. On the ebay site it also says make sure to resolder the transformer joints. When I turned on the monitor the color bar screen appeared in the bottom left corner for about 3 seconds and then disappeared. Then the power on LED started blinking again - back to the original problem. I'm going to attempt to resolder the joints. Any more suggestions from anyone with experience fixing the problem?

3 monotors with the same problem???

Posted on Sep 22, 2008

I bought a new acer 19" . i will try to change the capacitors and see how it works. if not, i will try the power inverter option. but my new lcd itself cost me 100$ after rebate. so paying 70 pounds for an inverter is unwise. previous poster, I am sure it is problem with monitor and not the connector coz it doesn't do the self diagnosis. thanks for all the responses so far.

Hi, I belong to another group, and posted this same question, due to an E172FP that I bought knowing it was faulty. The person who answered my post stated that he had just been doing a study on this because of a customer. Apparently it is quite common with this model. The monitor is made by samsung and is good so I'm told, but the electronics is made by another company and this is prone to failure. The part in particular, according to the respondant, is the power inverter and he believes it could cost as much as £70. I have seen some inverters on ebay going very cheap. I hope the info may help.

Hi,other than suggest that you bring bring it to a qualified service personnel, the problem is might be too techincal and is inside the LCD monitor itself. Just to be sure, check that all the plugs and connectors going to the monitor are tight and secured. Wiggle it just a bit to make sure all the pins are seated. But then again, might it be your PC (video out). Try shutting down, reboot/restart. If this still doesn't work, try restarting in safemode (press F8) while booting, then start again in normal mode. If still no go, guess you're back to the first paragraph. Good luck. Hope this be of some help to you. Pls post again how things turn up.

Hi Tomccaw,
In this case your monitor is working fine. Your system is going to power saving mode. To resolve that remove your RAM and insert it. It will fix your issue.

The Monitor won't stay on


Try it on another PC first.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed DELL monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

My monitor keeps going into power save mode


Hello,

Its not power saver mode, when the display goes black and the power light starts flashing that is a good indication that the power supply is about to die. The Dell E172 monitors are noted for this problem. We have step by step repair guides posted on our web site at: www.ccl-la.com Click on the monitor repair link. The Dell E172 series actually has several sub models, check your specific model, the sticker on the back will have either E172FPb, E172FPc, E172FPf. We have guides for all 3 versions posted.

I hope this helps, if so please rate our solution.

After a few seconds after boot up, the monitor turns black, images are visible in the background, but very dark. as if it is in a power saver mode.


Do you have brightness adjusting software. if so change the settings. if not there is something internally wrong with your back light.

Press power on... screen flashes on (blink), then goes blank and power button flashes


dpelrod727, Yes, the "switch-mode-power-supply" is in "partial" or "full" SHUTDOWN mode. Reconnect E172FP to a fully booted KNOWN good PC with the win-desktop as the displayed screen. Check with flashlight to see if your LCD panel is both BLACK and BLANK, or just BLACK by holding a bright flashlight 1" from screen at different angles even though the screen appears to be blank. If very faint image of desktop is seen then your SMPS is still half alive. Here are your options in either case. 1. Trade in for new. 2. Try Dell for a cash+old swapout for a Refurbed unit. 3. Check out www.ccl-la.com/badcaps, www.badcaps.net, www.lcdparts.net, and YOUTUBE long video clips dealing with LCD monitor disassembly and LCD repair. could be helpful in making decision on what to do.

How do I get a monitor out of hibernation mode? It is not responding and did not reset when I rebooted.


Try using the power button, which usually takes the computer out of hibernation. Also, the mouse and keyboard can sometimes wake the computer from hibernation as well.
If the computer is still stuck in a hibernated state, hold the power button in for about 5 seconds so the computer fully shuts down and power it back on.
Good Luck!

Dell E172FP 17 monitor keeps blinking


That sounds like the backlight inverter board. Check ebay for the board or a repair kit for it.
