    Proview 900P Board Problem (with pictures)

    Hello everyone. I'm so glad a forum like this exists!

    I bought a Proview Model 900P Product Number Pl916s2 at a flea market for 3$. When I took it home and tried it, it only is able to display for a few seconds.

    Curious I opened the monitor and hoped to see a problem. I found that the board (Mirage Electronics Pl-170DTLA) is burnt. I attached a picture of the front of the board and back of the board to this message. I'm not sure what this burnt component is. (Is it a transformer?) I'm really a newbie to all of this, and am just hoping to learn something because I've always been interested in computers.

    Does this look like the board could be fixed or would I need a whole new board?

    Any thoughts/ideas would be greatly appreciated. Thank you so much.

    That is an inverter transformer, and is probably the cause of the problem you described. The board is probably repairable; what numbers are on the transformer?

      Thanks so much for the information, PlainBill.

      The numbers on the inverter transformer are a bit hard to read. I think it says:
      730-703-1700TLAH<B>
      EEL19-AD1700 HL 0604

      I'll attach a picture of the numbers just in case.

      I think it is so great that it could be repairable. I'm willing to try. I've never soldered before, however, it sounds like a great learning experience. Thanks for the help!

        It sounds like you have 2 seconds to black. A bad inverter transformer is certainly one of the causes. If you are new, have a read through posts #19 and #20

        You can also test the inverter transformer if you have a multimeter to see if anything damaged.

          Not much luck finding a transformer for that inverter. The power board is available on eBay at an unreasonable (IMHO) price.
