    ACER AL2416W - Screen goes off after 0.5 secs but light stays on power button

    Hi guys i have an Acer AL2416W monitor. I have had the thing for probably the best part of 4 years and it's been great.

    Recently I have started to get a problem.

    When i provide power to the monitor i get a green acer logo pop up briefly then the screen turns off (the power button still has a green light on it).

    If i yank the power cable out and in a few times i can sometimes get the monitor to stay on but the issue has been getting worse.

    Once the monitor is on it stays on, it's just the initial turn on stage where it will switch off.

    I'm comfortable with a soldering iron (not a guru, just comfortable). I presume i will need to replace some parts. I have a local maplin store close to me.

    Any ideas on what i can check?

    Many thanks

      And the pics
      Pic1 - Looks like C34 is bulging bad out of the bottom and C36 has rust?


      Pic2 - Other side of board looks fine

          You might try to get this moved to the monitor section, you will get grater response.
          Pictures of the power supply and inverter will help a lot, a close up photo of the entire power supply and inverter using managed attachments.
          I have had two, and there have been others that replacing the capacitors particularly on the inverter has solved the problem. If there is more than 1 fuse on the inverter they should also be checked.
          Whatever I do, I consider it a success, if in the end I am breathing, seeing, feeling and hearing!

              Seconded, it looks like you only linked to thumbnails of your pics, which aren't very helpful. Crop/resize as close to 2000x2000 and upload using the attachments function.

                  just updated the photo links.

                  If a mod can move this to the correct forum area that would be much appreciated.

                      Thread moved.

                      That's an odd way to mount those caps.

                      I'd replace any of those caps, whether they appear to be failed or not. C34,35,and 36 are all failed or failing. The rest likely aren't far behind.
                      Ludicrous gibs!

                          Ok so i just ordered 10 caps:
                          http://cgi.ebay.co.uk/ws/eBayISAPI.d...:X:RTQ:GB:1123

                          Hopefully it'll be these that are causing the problem. Does it look as though i've order the correct caps? The ones on the board say 35v 100uF.

                          P.s. Cheers for moving the thread

                              Hard to tell, since the seller did not list the brand/series of the caps.

                                  Ok so what do you mean by brand/series? Like Nike/Addidas?

                                  How will that make a difference? In quality? In efficiency?

                                  Maybe before i fit them i should take some photos of them and list them up here, i bought these one's purely because of the "long life" description.

                                      Yeah, just that Nike and Adidas didn't make caps last time i checked.

                                      In both... as in if you buy the right caps you won't have to replace them every year.

                                          Hello Everyone!

                                          I have an Acer Aspire A315-42 laptop. I generally leave it on for long time by closing down its lid (so it enters the sleep mode). Recently, it rained quite heavily in out area. And the humidity and moisture seem to be high. So one late evening, after I opened the lid and turned on the laptop, it did power on as the blue light turned on but after it booted to the desktop screen, just 5-10 seconds after both the screen and blue light went out and laptop shut down (the blue power light turned orange). And after 2-4 seconds that orange light went off and the laptop died.                                          ...
