Dell 1907fpf will not power on.

Hello,
Whe i plug in my Dell 1907fpf, i get no power led, and i cant turn the unit on. I opened the case and found a blown fuse which i jumpered, still no luck. tested the buttons and they seem to be in working order. Have some voltages going into the button board, but without schematics, i cant tell what its supposed to be. changed out 2 mosfets and also no luck. Everything seems to be in order. Can anybody help?

    Same exact problem and model as shadyb92. I suspect a known bad part that Dell's not reporting. Any luck with this?

I got a dell monitor. model number 1907Fpf. i plug it in via DVI and its power cable and it wont turn on. the power button just blinks at a steady rate and dosent react at all when pressed.


Does it do the same using VGA cable? Same problem with another PC?
If it does not work with other PC, then you will have to take it apart.
It may be in the shutdown/restart mode due tp shorts circuits.
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), 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.

The screen flashes on my Dell 1905FP Monitor, Is there a fix?


Hello,

This is a common indication of bad filter capacitors on the power supply board. Below is a picture of the power supply board with the problem capacitors circled in yellow. The repair is easy, you just need to replace those capacitors and the unit should be as good as new. Below the picture is also a link to a full repair guide showing how to dis-assemble the monitor and what parts need to be replaced. the repair guide has a full parts list for the job.

My computer doesn't load on the screen as I turn it in


A solid amber power LED on a Dell System is indicative of a no post. There are 4 diagnostics LEDs on most Dell Towers (Either on the back marked ABCD, or on the front marked 1234) they can give more details of what the POST problem is.
Troubleshooting: Disconnect all external connections to tower except power, turn it on, see if the LED indications changed. If they change, then connect disconnected items one at a time till the failed item is found. If no change, the open tower, remove all PCI expansion cards, see if system will boot. If still no change, then most likely a motherboard failure. Take RAM out, see if you get a Beep error code when powered on, if no beeps, replace motherboard. If it does beep, try RAM modules one at a time, if it boots with 1 but not the other, replace the effected module. If no boot, with either replace MB

LCD monitor no display - flashing power button


hello, my best guess is that the refresh rate is set for a crt monitor. hook your old one back up, if you can. and change it to 60 hertz or 70hertz. go 2 display properties then settings then advanced; then monitor. set the refresh rate as i said and turn off the computer, hook the new one back, and you should be good to go. good luck! and please rate this solution. if you need further assistance, reply

Monitor Screen goes black seconds after turn on-


I ended up fixing my problem, but I'm not sure what the solution is. I had some faulty electrical equipment that I was using to power the monitor (220V to 110V converter and a bad power strip) and I got rid of them. I was using the converter because I moved to Israel and I thought I needed to feed the monitor only 110V, but I now realize that the power cord for the monitor has a built-in converter that accepts 220V input. Now the monitor is plugged directly into the wall and is working fine. Try using a different power source (maybe the wiring or plug you're using is faulty). Good Luck!

Dell E151FPb 15" LCD with power LED blinking.


The problem may be a loose connection. When I turn on my monitor, the green light blinks and a flickering white screen appears for a brief second every time. There must be a loose connection on the power board which may be causing this. The easiest solution is to tap at the back of the monitor. This will reconnect the loose end and the monitor will work fine until it gets disconnected again. I will open my monitor soon to find the real problem. But it will take some time to find it.

I have A "Dell" E152FPc, and I have found an open transistor (Q201) on the Power Supply Board. My monitor comes on nice and bright for approximately 2 seconds, then goes dark; the power LED is steady. The voltage to the PWM IC is waky.
Before you try any hardware troubleshooting go to your control panel and turn off any power management options.

No power in dell e173fpf


I would expect the same (new) part failed. Try another dual diode otherwise you may be chasing the problem around the board.. Good Luck, Tim
