    Hi have the same problem. When I press the monitor's power button the screen is normal for 1 sec and you can see the WIn XP log-on screen but then the monitor goes black. The power button flashes green. If you press and hold the power button the monitor does turn off. When pressed again it does the same exact thing.

    I have the same issue. If I disconnect the signal from the CPU the light turns amber. This happened after my kids turned the monitor slightly ( 20 degrees). I have seen this question a lot but no answer yet. Where can a person take a monitor to have it checked? I live in a fairly small town!

E172FP (Black) 17 in. Flat Panel LCD Monitor: Dell monitor problem, its the power save mode agai...


First, try it on another PC, check or try another VGA cable, if it still does not work then you need to open it up. Dell monitors are known to have bad solder connections, bad caps. See my photo albums of failed Dell monitors to get some idea what to look for.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, 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.

The power button is not working it blinks a green light


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.

What could cause a dell flatscreen monitor to go


Probably a bad power supply in the monitor. One of these days it will go black and stay that way.

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.

Dell E172FP, monitor blinks then goes blank or black


This is a known problem of the Invertor board.If you are technically able you can open the monitor and resolder transistors 2sc5707 as also all pins of 4 yellow invertor transistors that you can see near the backlight connectors.

Dell E172FP 17 monitor keeps blinking


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

Blinking monitor power button and flashing image


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.
