    There are at least two caps. bad, I circled them. there may be other problems as well, have you checked any voltages?
    Try replacing those two and see if it fixes it.

        Is this the same set you fixed in oct 2011 - I am surprised it has lasted so long. You were advised at the time that the caps you used were not good enough - did you go back and change them ALL as suggested by at least two experienced members, If not , you are now paying the price for that and you need to change them now with something decent like panasonic FR series though FM and even FC will do if you cant get the sizes in FR and FM.
        Probably no point checking voltages until caps are replaced.
        Please upload pictures using attachment function when ask for help on the repair

          Don't change just the two bulged caps - change all of them. Why? Because suitable replacement caps are easiest found online (local stores usually only have "general purpose" caps, which are inadequate for this application and won't last long - hence it's not suggested to use them). So, if you are going to buy caps online and pay for shipping, you might as well get replacements for every capacitor in your monitor's power supply (except for the tiny ones and big 400V cap - that one usually does not need replacing).
          Better yet, if you have more monitors like this one or other LCD monitors that have bad caps (hint: check model numbers with badcaps.net search engine), then get some extra caps.

          You are not necessarily limited to Panasonic FC, FR, and FM, but they are nearly universal caps when it comes to monitors and are of very high quality, which is why selldoor usually suggests them.
          Other choices that could work in LCD monitors are:
          Rubycon ZL, ZLJ, ZLG, ZLK
          Chemicon KY, KZE,
          Nichicon PW, PS, PM, HE, HD, HV

          **AVOID eBay for caps**
          (Or if you are really set on buying caps from eBay, first post a link to the listing here before buying anything. There are just too many fakes and these fake caps don't last worth a squat either.)

            AOC AG493UCX 49-inch monitor - Firmware request
            by wattage
            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...

            by pajdek
            Hello, i have some issues with my laptop Lenovo Y700-17ISK (motherboard BY511 NM-A541), it started when i turn on the laptop, but the lcd wont turn on, i then connected it via hdmi to tv and screen was ok.

Conncted power supply and tuned on my laptop, the lcd turn on, it started to load os, then it turn off, after a second it turn on, then after like 3 seconds turn off again, and so on.

            I need help with my friend Sony GDM-FW900 24” CRT
            by matthewmcconaughey
            Hello, Badcaps is my last resort. I am the first owner of the monitor. I reached almost every repair store in my area, but no one even wanted to hear about troubleshooting an old CRT monitor. At this point, I have been trying to figure it out by myself, but I have no idea where to start or look for.

            I wish to know how to think and locate a failing component. I will put all my efforts to learn and contribute.
            1. It started with a bright and greenish picture upon starting a cold monitor.
            2. About 2 years ago, only on the cold boot, the screen started to occasionally flash with
