Gateway fpd2485w lcd shows video then cuts off

Hi I have a Gateway fpd2485w that powers on shows gateway logo then the video cuts off. Every time I unplug the video cable from the monitor and plug it back in it shows video for a second and then cuts off. It appears that it won't hold a signal. Please help.

    UGH, I have the same problem also. On plugging it in, the Gateway logo shows for about a second then goes off. If I disconnect the DVI cable, wait for the monitor to suspend, and then plug it back in, I'll get the desktop to display for about a second before going off again.

    I am also having the same problem, if you turn it off and wait a while, then turn it back on, it usually fixes the problem, if that doesn't work the first time, I repeat the process until it stays on. I know this is just a temporary fix, I'd like to know the actual solution as well...

    The off/on trick worked the first two times but I haven't been able to
    get it to work again. I'm still trying to find the problem. I came
    across a similar post for a Samsung monitor that exhibited the same
    problem. The person said that the power inverter was bad. After doing
    more research, it makes sense. The backlighting is fluorescent, which
    requires AC. We know that the bulbs are fine because the picture comes
    on for a second. I'll investigate more and post what I find.

I'm pretty sure the inverter board is bad. you have to replace it if you can or you can let someone else do it. you should find some on ebay for about $80 (not too bad compared to the cost of the monitor: over $200). but its up to you. But first, you should find out if you are still under warranty. good luck. please rate!!

Had a power outage and USB ports on side of monitor do not function now. I had it plugged into surge protector. Any suggestions?


The usb ports are powered using a fuse in series of approx 500-750 ma to avoid damage due to short circuit, check for the blow fuse that is in the path of usb ports.

Need to remove the outer cover on a Gateway


If you get power to the controls and you don’t have the startup sound or see the gateway logo when you plug it in, the main board may be bad.
If your picture was pinkish or dark at the top or bottom when it was working then you may have 1 or more of the bulbs failing.
If you have the startup sound and see the gateway logo and the screen just flashes and the power buttons stay lit, then it sounds like probably the inverter may have went.

Take the screws out of the bottom rear edge (these hold the front trim), and the 4 big black ones at the middle of the back that hold the stand bracket.
The trim then unsnaps. {Be aware of the small ribbon to the power button board on the right edge}Start at the bottom and release the trim (pulling up the trim on the screen side usually starts it off), then work your way up each side bottom to top ((a pocket knife or thin putty knife even a credit card, will help release the catches as you work your way up)
Then unsnap the top edge (rocking it while lifting helps)
Disconnect the ribbon at the power button board, (Tiny latch lifts up on a hinge and ribbon slides out)
Once trim is off, remove the 4 corner screws that hold the screen in. Then the screen will lift out with all the guts. You may have to pry up on a corner with a screw driver to get it started.
The inverter is under the medium size metal case.
The power board and main board are under the large cover.
You’ll then have to remove a bunch of screws including the usb board ones and unplug the bulbs and wire to the screen
then the power board and control board is under the center area under the metal cover
Shout if you need more info.
If you email me a good picture of the board , I may be able to get a better idea if it is the inverter from a visual.
Thanks Fran

Trying to fix lcd Gateway Monitor.


There's a couple capacitors you need to replace. On the video board, not the power supply board. There is (3) 470uf16v on the video board. They have to be the smaller ones, you can not use the larger ones (they will not sit flush onto the board) Any questions, e-mail me at Andrew@CreativeAudio.biz

Gateway FPD2485W how do I replace the LCD


For most models, replacing an LCD panel is very close to the cost of a complete new monitor.

Slow start


(I'm copying a guest's comment above. What Gateway told him does seem to work - although in my case, the monitor was slow to start when plugged directly into the wall, and it was immediately fixed when I plugged it back into a heavy duty power bar.)

hey, I had the same problem. Gateway told me "Plug the monitor power plug directly into a wall electrical outlet
or a different wall outlet by removing any surge suppressors." I did that and it works. It might be a certain kind of power bar they do not like. It worked for me so try that and see if that helps.
