    Gateway fpd1975w

    Ok so I've got this Gateway 19" LCD monitor. What it does is, if it has been powered off, meaning unplugged, it will work if the computer is on and the monitor is plugged back in with an active signal going to it. If the computer is restarted, it will not work. The monitor needs to be again unplugged, wait about 10-15 seconds, and plugged back in. That's the only way it will work.

    Since I'm new to working on LCD monitors, I have two questions:

    1. What's likely wrong with it? What do I need to know about working on these things? I can solder well, and have plenty of caps ready to go. I've replaced lots of bad capacitors on power supplies and motherboards, but I've never been into an LCD monitor.

    2. How do I get the f***ing case off the thing?

    Thanks in advance!
    A man convinced against his will is of the same opinion still.

    It's probably bad caps, 3 I bet. I got one of these and it wouldn't come on, just flashed the power light, I think.
    It takes 3 35v 470uf caps, they are actually 25v in it, but I replaced them with 35v ones, and it works great now
    This model, and the 17" version are notorious for this problem.
    As far as getting the back off, you will have to either use a flat head screwdriver and pop/pry it around the edges, or get a spudger (sp) opening tool, they have plastic and metal ones, the plastic ones are called black sticks by apple.
    I started at the bottom, so the little dents/scratches are less noticeable.
    You will probably end up breaking some of the plastic tabs that hold it together, but it will still go back together fine afterwords.
    You might also have to take off the stand, mine didn't come with one.

      I had the same problem. I manage to open the case.
      But I have no idea where to find the caps, LOL.
      Can you tell me where are they. Thanks. Luna.

              I kept looking and found the solution. Replace the Caps.
              Also found the power board but was out of stock.

                Yes, replace ALL the electrolytic caps, even those that look good. You're looking at about $5.00 (US) worth of caps there.

                    Which caps are usually the problem? I would prefer to replace 3 instead off ALL of them if possible. Is it usually the 25v 470uF that are the problem caps?

                            105°C, low ESR. Read the 'Which Caps Should I Buy' thread in the FAQ.

                                It doesn't usually matter. The connectors are polarized so they can't go in 'upside down'. On two pin connectors, the two pins are the feed and return lines from a single CCFL.

                                It is common for the repairman to mark the connectors so the plugs will go back into the same sockets they came out. USUALLY the wires will have a certain 'lay' to them so a good guess can be made over which one came from where. I've never had a monitor burst into flames because I put the plugs into the wrong sockets.

                                As my mother-in-law used to say, "If it isn't smoking, it isn't cooking".

                                    I've got a Gateway FPD1976W that was doing the same thing for the month I had it (given to me for free by my daughter's great grampa because it blinked on and off on him) until 4 days ago when I woke up to the blue botton blinking on and off.

                                    When I eventually did get it fire back up and stay lit (by completely unplugging and draining it of power for 30 seconds), it was a grayish white screen and the OSD buttons didn't work at all. No warning in the corner about native resolution either. Pressed the power button and it never came on again. All it does now is if I plug it in and hold down the power button, the button itself will blink orange momentarily every 3 to 5 seconds.

                                    Looking to recap it see what happens. Luna's pics gives me an idea of what to expect if Gateway used the same power inverters for the FPD1975W and FPD1976W models.

                                      Did anyone ever find a fix to this problem with this monitor? I'm actually concerned about a different symptom with this same monitor. Maybe it's the same but here it goes.... This monitor (FPD1975W):

                                      with no input signal - cycles through 3 screens of different brightness then one screen of test pattern and then goes back out with power button LED change from green to amber, as usual.

                                      with input signal - Monitor simply cycles through 3 screens then test pattern then keeps cycling.

                                      Just for the heck of it, I desoldered all caps on inverter board and checked with capacitance meter - no probs there. It seems as if the digital processing board is not interpreting the signal it is getting but somehow it knows theres something present to keep cycling.

                                        A capacitance meter may still indicate a capacitor has the correct capacitance even though it's ESR is high. What brand are the caps in this monitor?

                                          Normally, I never post repairs this quick after I do them, because… I am usually very slow. But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...

                                          Hello Badcaps Community,

                                          I purchased a preowned AOC monitor that is not working and out of warranty. It was sold as not working. I am looking for guidance on self-repair. In particular, I am after the firmware for the monitor. At the end, I have included monitor model information and links to pics and vids of the issue.

                                          The problem is that it will not display a picture on any of its inputs. And the on-screen menu does not appear. The power button works properly. It powers on with the remote as well. But the on-screen menu does not appear, even when not connected to any...

                                          Hi Everyone

                                          Lately I am experiencing the deja-vu incident on one of the led monitor like this.
                                          https://www.badcaps.net/forum/troubl...lashing-on-off

                                          The monitor is HP 27es LED Monitor
                                          https://h30434.www3.hp.com/t5/Deskto...e/td-p/6804692

                                          The monitor will randomly blackout and display no signal and will recover again.
                                          Sometimes need to power and off again to restore the display but...

                                          Acer S231HL LCD LED Monitor - No power then works after unplugged for a month
                                          by mobotest
                                          Hello,

                                          Monitor:
                                          Acer S231HL LCD LED

                                          Adapter:
                                          Delta Electronics ADP-40PH 19V 2.1 AC/DC

                                          Symptom:
                                          No monitor power LED light. Monitor did not turn on.
                                          Adapter measured 18.92V at adapter barrel connector.
                                          Then after a month of leaving monitor unplugged, monitor started working again yesterday.
                                          Adapter still measures 18.92V.

                                          Questions:
                                          1. Is 18.92V output within spec for a 19V adapter? or is it a sign of future failure?
                                          2. Does the described behavior indicate some component in the monitor that is faulty...

                                          4 weeks ago i launched Metro Exodus Enhanced and during cinematic advertisement part ( 30 fps ), pc just shutdown.
                                          Also monitor flickered with NO SIGNAL 10 seconds after shutdown. So only monitor and pc was affected.

                                          Next i pressed only power button, rebooted again and its fine again. Happened once and i cant reproduce.
