    I have the same problem. my monitor doesn't work, just out of the blue. I tried all power supply and cords.

    Yup, sounds like exactly the same problem, the blue power light appears for a fraction of a second and nothing, was working fine yesterday with no signs of any problem.

    The solution sounds technical, and not something that I would be able to do myself without guided instruction... is there a hyperlink with futher information that may be of help?

    Regards, Alfred.

Hi the SMPS needs to be checked - some of the failure prone comps., Bridge Rectifier and Power Transistor check them after disconnecting power completely , the large electrolytic Cap., will hold charge even after disconnecting the power so be very careful. The substance around caps., is epoxy so as not to let them explode in the event of short circuit

Check the line cord to see if it can carry power. Check the connection from the line cord to the power supply. It may be that the soldered connection is broken there and needs re-soldering. Check to see if it has any external or internal fuses that need replacing.

The power chord for this monitor is attached to a power adapter which converts mains voltage to 12 volts.
Check the power label on the monitor for the amp rating of the monitor and get an adapter that has an output of 12 volts and with the amp rating on the label or higher. Make sure the 0.3" power plug fits the monitor.

Dell Optiplex GX280 Power switch flashes white light rapidly system will not turn on Fans do not start

Outlet - unplug the power cable and put it on an outlet on its own Power Cord - make sure you remove the power cable from the back and plug it back in to make sure you have a good connection. things that cause this blinking light: Power Supply -open system and follow cables to make sure its connected well to each part. I/O Panel - this is where the power button is at . just open the system and follow it behind the power button.the flat cable going to the mother board , disconnect it. plug the power cable to the wall and if the system starts up then the power supply is good and the the cable that you just disconnected is bad.

If it still doesn't power up remove
hard drive
dvd/cd drive
and start the system.
no luck then it is the systemboard.

Pwr supply not getting power to the mobo.

No fuse, but they are relatively inexpensive, about $30.00. You can have yours load tested by a reliable local tech to confirm it has given up the ghost...and they'll probably be happy to supply a new one as well...
Here's a startup troubleshooter that has more info if you're interested in self-testing...

I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.

Check the power cable/cord for continuity with your multimeter ok. Make sure also that the mains or power outlet is giving the right voltage. This is also done by the use of the multimeter - either analog or digital - any one at your disposal can do ok. if all work well, then the power supply unit should be removed from the system unit, connected directly with the power cord and then bridged. That is at the secondary output which connects to the system motheboard. Locate the power-on cable(normally green in colour) and bridge it with any black cable on the same row. The cooling fan at the back of the power unit should be rolling if the unit is ok. Good luck

I only have the mini tower - need appropriate cabes, cords, etc.

First, I suggest finding a monitor first as some have an 'attached' monitor cable and some don't. (No use buing a $15.00 cord you don't need) As far as a mouse goes, believe it or not, I've found the best prices for a good mouse at Home Depot and Publix Supermarkets. E-bay and always have great prices on most any cord.
All PC power cords I've ever seen are the same (about $11.00 at any Staples, CompUSA, Best Buy, etc.), They are will only fit PC's and VGA (old-style) monitors.
Any monitor should work just fine. For used I'd suggest and for a new LCD you probably can't beat (new owner's of CompUSA).
Any mouse & keyboard will work also. Good Luck!

you need to test the large connector from the powersupply to the circuit board inside the computer. You should be reading small single volt numbers. More than likely its a bad powersupply though.
