    The part is a Delta 8904C-F power controller. I believe it regulates power to displays, but I'm not too sure about that. It apparently needs replacing. Here is a link to buy the product.

    Don't buy those $10 PSU "specials". They fail, and they have taken whole computers with them.

            Okay. At least this isn't a MicroUSB connector you need. LOL.
