    Asus P5P800-vm with blown 9T15GH fet

    as seen on these pix. it's all i can see.

    symptoms were: smoke smell, no video, fans spinning ok, hdd light on all the time...

    and those chemicons look shaken.

    anybody seen this before? i've found some info on russian forums, but that was it. searching usually finds only asus boards with this issue. and not much of it anyway(seems to be a rare problem).

    how to explain it? marginal quality part? chemicons? bad design overstressing components?
    what's weird is that these are not usual cpu supply issues, but north bridge, it seems(if agp is offline).

    this french thread talks about replacements

    The regulator near KZG caps seems burned (black spot): is it burned or is a compression glitch?

      well, if it was a compression glitch, this thread wouldn't have words like
      "blown fet", "smoke smell", "no video" in it...
      <wink>

      yes, burned, and seems like a most probable cause for this system not producing any video, be it onboard, or inserting some agp card...
      it was overheating, and now it stays rather cold..hehe...
      notice the swallen chemicons: they should look like the one that is just right to the ram slots...

      here's another mentioned replacement for this fet
      http://monitor.net.ru/forum/asus-p5n...nfo-75162.html
      (90N02 (можно 60N02, 70N03 и т.д.))
      here's one more report
      http://monitor.net.ru/forum/asus-p5r...fo-198107.html

      overall, it seems to be rather rare malfunction...

      i need to check if any of those replacaments are available here...

        [cough] Sorry, my mind get easily rid of post titles.
        I didn't caught you already found a blown fet so I pointed it out.

        Tried with a PCI card?

          that is a vdimm reg.
          bad ram,or improper insertion causes this.

            yes, that's a possibility: there were some problems prior to this that looked like bad ram...machine stop bsod type of thing...
