    I would think the College will have all type of caps in the lab for the students to see what various type of caps there are.

      Just got back from holiday leave and finally received 30 of these, the old one is: an 80LL15T-7-YS G 0523, and all 30 of these are:
      80LL15T-7-YS G 0716.

      Though if that was simply a bad connection as you said then the old one is possibly still good.

      I am working to line up a DMM (to check capacitance), frequency generator and oscope (the university labs are closed currently) to work through those service guides you graciously forwarded. Though, I noticed that the service guides sent are -2 and mine is a -4. It appears you all have been doing this for awhile and that these are likely all that I will need.

        I didn't really want 30 of these inverter/ transformers, but the parts which they used to make this old monitor are hard to find and you almost have to go with whatever you can find. If I do end up using this part, I think it is good judgement to replace both of them so they will match.

          I finally got onto a DMM, the capacitor is giving 0.018 microfarads. I'll try to find a stats sheet. Wait, I think somebody else talked about this in this string.
