    2 seconds to black on FPD2485W.

    Hello, I have what seems to be a very common problem on this monitor. Upon turning on, I get either the gateway logo or my desktop for a moment, then black. The buttons and speaker all function as if the monitor were working.

    I apologize as this probably sounds like a very newbie question, but I'm not sure which board is bad. It seems to be either the power board or inverter board, but which is the likely culprit? I bought this ebay auction:

    http://cgi.ebay.com/ws/eBayISAPI.dll...=STRK:MEWNX:IT

    ...but now after reading this forum I'm not convinced that replacing the capacitors on that board will solve my problem. This eBay auction that repairs this issue has the buyer send him the inverter board:

    http://cgi.ebay.com/REPAIR-4-Inverte...item5640b80516

    I'm sorry if this is way too beginner level, but it would be awesome to be able to repair the display rather than throwing it out. I appreciate any input you folks might have.

    The problem is called 'two seconds to black'. There are a number of possible causes, one of them is bad caps. The first step is to open the monitor up and post some pictures. See my signature for some links.

      Pictures are always a good Idea to post.
      I have a local recycler that I get monitors from .I am seeing quite a few gateway monitors come in it looks like they were made in 2006 and 07, They have had capacitor problems causing the two sec to black problem, The capacitors did not always show signs of bulging, I would recommend putting together a list of the caps needed, Including the small ones around the SMPS transformer and replace them. You can usually spend less than ten dollars.
      There are other problems that can cause a two sec to black problem but I think capacitors would be a good place to start
      Al.
      Whatever I do, I consider it a success, if in the end I am breathing, seeing, feeling and hearing!

        Yep, mine was manufactured in 2006. I am replacing all the capacitors on the power board today. If it doesn't work I will post some pictures. There are two capacitors on the inverter board as well. Could those be the issue?

          Re: 2 seconds to black on FPD2485W.

          What wattage soldering iron should I be using to get these capacitors out and resoldered? I have a 15W iron that I usually use for electronics but it is not melting the solder in the existing joints.

            Re: 2 seconds to black on FPD2485W.

            Caps on the inverter could be an issue, yes. 15W is a little low but maybe workable. Try adding some fresh solder to mix with the existing and see if you can get it to flow. Are you using a sucker or wick to remove?

              15 watts is a lot light for this. I use a 40 watt to unsolder, and a venerable Ungar 27 watt to solder in the new. With the 40 watt I can move from lead to lead, rocking the old cap out. Then I use a dissecting pick to clear the molten solder out of the holes.

              What caps are you using for replacements?

                I'm using the caps from the eBay auction I posted in the OP. I'm going to grab a better iron now. I'm used to much more delicate work so my irons are very low wattage.

                          I just use the irons from Radio Shack. I know that's probably blasphemy on this board but they work for me!

                                Says in their listing they only use panasonic caps. Dosen't list series, but they are all 105c.

                                  I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

                                  Upon bringing it home and plugging it up, it showed a standby light.

                                  I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

                                  The screen seems to blackout and stay black, but with a flashlight I can see the display.

                                  With my Playstation 4 connected via HDMI, and running a game I can hear sound.

                                  Problem

                                  This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....

                                  When the display is turned on the viewsonic logo displays in the uppper left for 2 seconds then the screen goes black, the power LED is green (on) and when a computer is connected...
