    Apprentice,
    Thanks for the imput, I'll do it and let all know if this solves the problem. I also have a new problem, it appears that in the process of unpluging the the monitor from the mother board, one of the wires has come loose from the grey connector. If you have a suggestion on how to reconnect the wire and/or replace this connector, please let me know. My email address is jdsatter@sbcglobal.net.
    Thanks again for you help,

    Sprint6,

    I really appreciate hearing back from you. I just hate the thought of having to trash a $600 monitor. I would be open to use Yahoo Messenger except the computer I'm on doesn't have it installed and the owner would rather not have it. I have sent you a duplicate pos, including my phone # and a pic. to your email: ru4rehab@yahoo.com.

    That being said, I'll attempt to describe my problem a bit further, as you have requested. There are 5 groups of wires that connect the screen of the monitor to the motherboard of which I have disconnected(unplugged) each time (4) that I have accessed the motherboard. If you lie the monitor down, face up, with the screen removed, on the right-hand side, there are 4 places where 4 groups of wires connect to the motherboard. If you look at the back-side of the screen, you will see two of the groups have 2 wires each(both white) while the other two groups have 4 wires each(each consisting of a yellow, black, Lt. blue and a pink wire), at least on my monitor. These groups of wires have been further grouped into 2 groups by the use of thin chrome tape wrapped around joining a group of 2 wires with a group of 4 wires. These two groupings of wires plug into the mother board right next to each other. Hopefully this all makes sense to you so far.

    My problem, aside from having the monitor light up for about a minute and then go dark, is that it appears that while I was disconnecting one of the small 2 wire groups from the mother board, I inadverntly pulled out the small white wire from the gray female plug used to connect the two white wires of that group to the mother board (see pic.). My mind says that all I have to do is snip the other wire, get a new female plug like the one used, strip a little of the plastic coating off each wire, secure each wire into the new plug and then I'll be good to go for re-connect.

    If this is correct, would you know the name of that kind of plug/connector and where could I get such a plug. Also, regarding my orignal issue, can you be a little more explainatory regarding the diod you recommend me replacing? To me, a diod looks like a resistor. How do I know what to get? I would think that I should be able to get both at Allied Electronic's which is where I purchased the caps that I have already installed.
    Again, thanks for your time and willingness to help me save my monitor. I look forward to hearing from you soon.
    Sincerely,

    JD Satter

    Saw your post “Apprentice, Thanks for the input, I'll do it and let all know if this solves the problem.

    Not sure what you mean by unplugging the monitor form the mother board connector.
    If you could explain the problem a bit deeper, of have a photo of the connector in question, would be a great help.

    If you would like for me to call, which is the best way to figure out what may be involved with your unit , please give #, and when best to make contact.
    Also you can use yahoo messenger to get a quicker feedback, ru4rehab@yahoo.com

Why does my gateway fpd2185w monitor screen go black after showing my desktop for about 1 minute


David

That problem is calle,refresh, thats happend when the monitor try to refresh the page or "clean" the page, you can set that in your video driver options. but if you don't have a video driver for your particular video card already installed, you don't have a right refresh rate and this delay, may happend.

I HAVE A Gateway FPD2185W that goes on for a split second then goes black I have already changed the 8 capacitors that i was told to change is there anything else i can do because it still does the same...


make sure there are no briged solder connections. make sure all the inside connectors were properly inserted into the connection on the boards. Check to see if you have the correct input settings by pressing the pushbuttons on the right lower side of the monitor. check all cables or switch to dvi or agp cables.

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.

Gateway fpd2185w capacitor fix question


to take solder off you can get some cross wire called DESOLDER this copper wire soaks up the old solder, by heating this new desolder the old solder will jump into it and clear your way. I like the Techspray #3 no-clean model 1822-5f
and its made in the USA!

When you say that you replaced "all the capacitors" what are
you referring to? There are 8 identical capacitors in the corner
of the Power Supply/Inverter board that go bad, but there are
also 3 capacitors in the corner of the Main board nearest the
connector that goes to the power supply that can also go bad.
These are associated with the part "U15" nearby, which is the
3.3 Volt voltage regulator for the main board. If these caps go
bad, this regulator can fail to operate, and you will get no display.

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

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.
