When I turn on my 24" Gateway monitor, it powers up...and the Gateway logo flashes for a sec...but then the screen goes black. I have to turn the monitor on and off quite a few times before the screen finally goes to the password screen. Any Ideas?

    What is the model number of this monitor? Does it do the same with other PC? 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 monitors to get some ideas what to look for:http://s807.photobucket.com/home/budm/al... Post back what you see inside so we can guide you further and it will help out other people in the future also.http://www.badcaps.nethttp://en.wikipedia.org/wiki/Capacitor_p...

If you have it, reinstall the software. If you don't, type in the model and find the drivers and info online.

it is possible the monitor is going out


another possiblity is monitor setting--when the monitor comes from the factory they put setting in for the monitor, & you have to go in & adjust them to what you want
Windows 7
Go to control panel
Go to hardware & sound
Go to power options
Select a power plan
Which ever one you pick--click change power settings--to what you want the settings to be
And go to each power plan so the settings will be the same
Each time click save

For windows xp
Go to the control panel
Go to appearance & themes
Go to screen saver--at the bottom you will see monitor power--to adjust monitor power settings & save energy click the power button
The menu will say power option prosperities
Turn off monitor setting--click what you want it to be
Turn off hard disk settings--put what you want
Turn off system standby--put what you want

This is a common problem with many LCD monitors. The
printed circuit board that provides a stable voltage for the monitor to operate
from starts to fail. The PCB can be replaced, when/if they are available, or repaired
in most cases at a much lower cost. for more information on this email me at

Gateway FPD2185W

Hello,

The next thing to try would be to resolder all of the connections on the transformers in your monitor. If you can take a few pictures of the board and email them to me I will mark the points to check and send it back to you.

Same problem 2 seconds on, then turns black

The problem with the monitor is the power inverter board. I took my monitor apart and tested all the power outputs. The ones going to the main board where ok but the ones going to the backlight where different. I changed the three capacitors on the power board that where located between the two heat sinks I think it was the 1000uf and the two 470uf. They looked ok but when i tested them they where off. Next on the opposite side of the board with all the little componites there are a few dry joins that you have to resolder. If you cant find then you can just resolder the whole back board it should only take 30min. If you have no idea what i am talking about i would not sugest taking the monitor apart.

Your power supply may not be supplying the required electricity to keep your monitor on. Try plugging your monitor in a different electricity source. Your CPU may be drawing much power from the source and not enough is supplied to the monitor. You may plug the monitor directly to the UPS (uninterrupted power supply) if the cable end allows it.

Screen only stays on for 1 sec

Assuming you changed all the caps and did it correctly.
IF you get flickering, It could be a transistor on the inverter board.
OR !!! and probably more likely,
It could be one of the bulbs in the lcd itself is failing. It only takes one bad bulb to stop an inverter from firing up !! You can check them one at a time if you have another working monitor.
If you do unplug a good bulb from the good monitor and try each of the questionable ones, one at a time.
Doesn't have to be a gateway monitor to test it, just needs the same backlight plug.
