    Acer AL1706b flashing power light

    Hello, all. My name is Bruce. I'm new here, but an old hand at electronics. My dad was a T.V./radio/electronics repairman.(BPCB)
    I was given this monitor as "payment" for hooking up a neighbors new 19" and I use it as a second monitor. When I first hooked it up, it took about 10 mins to come on, with the power light blinking green. I experimented with turning it off nightly, and it took longer each time to kick in. I then left it on all the time, and covered the front with a towel to block out the light at night.
    The other night, we had a major t-storm and the wife turned off all the computers, monitors, etc. Now the monitor will not come on at all, just sits there with the power light blinking green. I was looking around to see if this is even worth trying to fix, and found this site. After much browsing and a search, I found a few threads with similar problems, and tried a few of the suggestions, (powering off at the plug, disconnecting VGA cable with power on) and it's still doing the same thing. I never thought about the possibility of bad caps, but it seems feasible.
    Would it be worth trying to fix, or not? Unit is about 4 years old,(Jan 06) but my old crt main monitor is about 10 and still working, although a bit dim.
    I'll have to see if I can find my old soldering equipment as well.
    Thanks.

    It's definitely worth fixing. You should be able to fix that one for about $10 or less if it is the caps. Take a look inside. The problem you are describing is consistant with badcaps.

      Might be the power supply trying to start, and cycling because of a problem.
      If it uses an internal power supply, open it up and post pics and caps info.

        Thanks for the info.
        I'll take a look inside later, as soon as I figure out how to get the back off.
        I can get a new 18.5" Acer X series monitor for around $120, so I might get one, but I still want to keep this one as a secondary anyway. I do a lot of 3D gaming work, so having 2 monitors is almost a must.

          Finally got around to taking the monitor apart, and I found at least 6 bulged caps on the power supply. Ugh.
          I picked up a 20" Acer at Wallyworld for $128 CDN, so I decided to fix up the other one and give it to my daughter for her computer. I'm using my old crt for a secondary, but next to the P205H, it sucks, but it'll do for now.

          Now to find and check my soldering pencil and see if THAT still works......

            Dont forget to check all fuses also.

              Most will recommend that you replace them ALL regardless if they are bulged or not. If 6 bulged, it would not be a stretch to think the others are going to die soon.

              Most recommend Panasonic, Rubycon, or United Chemicon for replacements.

              In Canada, you can check your local electronics store for these brands. If you order from ca.digikey.com, shipping and handling is $8 USD.

                Pretty pointless in this case IMHO. The symptoms are classis SMPS cycling, due to either the startup circuit failing or (more often) an overload situation. I'm having difficulty imagining a way that a failed fuse could cause either of those.
