Re: dell c2280

First I would double check all of your connections. Then I would try to seat and reseat the video card. If its possible try and use a different video card to test and see if that is the issue. There is a chance that you damaged the mother board during your power supply replacement. Dunno if that helps but thats what I would try first.

In a dell e177fpf lcd monitor all the capasitors fuses diodes in power supply and inverter board are ok.but the back lights remains 2 seconds.

Hello...I recently opened up my Dell E173Fpf monitor because the screen went black, yet the power button was green. I thought it was a capacitor problem. But before doing anything I gave the board a thorough inspection, looking for anomalies. I observed a substance, (later identified as silicon) puddled around the power connections. I gently removed the semi rigid stuff and didn't touch the capacitors as I had originally planned. I partially reassembled the monitor for a test run and it worked again. (Being 9 years old, I don't know for how long...) Only thing I can think of is that a spill happened at the factory and over the years it gradually "melted" to puddle around the wires behind the power input. (Weird, but that seems to be what happened.)

No input signal on monitor-not connected to tv-computer works fine except for the no input signal

no input or signal means that the monitor is not receiving any signal from the CPU and if the power light is amber then and the cpu works fine then there could be a problem with the cable connecting the CPU and the monitor ...check the cable.

Dell 24'' Ultrasharp went blank

I suspect the invertor supplying power to the Xenon backlight tubes has failed.
This can be reapired but may not be cost effective.
Ask for a quote from your local computer specialist but keep in mind the cost of a new monitor.

I need power cords for my monitor

The monitor needs a power cord and a signal cable. The power cord is a standard 3-prong detachable cord just like the one on nearly every desktop computer and many other electronic appliances.

The signal cable may be one of two types, depending on your computer's video connector. The monitor has connectors for both VGA (a D-shaped connector with 15 pins) and DVI (a rectangular connector) inputs. You need a cable with whichever type of connector fits your computer.

You should be able to find the power cord at Radio Shack, any of the big office supply places, or retailers who sell computers. The signal cable may be available there as well, or you can order from a number of online vendors.

The monitor also allows you to plug in a USB cable from your computer so you can plug in USB devices like a keyboard or mouse. For that you need the same kind of USB cable you would use to connect a printer.

You can view or download a copy of the monitor user's guide at Dell's site here:

Display works - but only for a plit second...

Lower your resolution on your computer. Usually when that happens the resolution is set higher than what the monitor can support. Lower the resolution and try again.
