Do-It-Yourself Story

Bought control board, when I took off back upper cover saw the culprit immediately, a capacitor had fallen out of its soldered socket and was laying on a sheet metal bracket. (not fixable by me!), the new board went in fine, had to watch a youtube video on removing the ribbon cable, but the connector transfers went fine, took an hour when all said and done. Take photos of the connectors to help transfer, but they are all foolproof anyway, with unique pin patterns so you can't put a plug in the wrong place. Some needle nose pliers helped remove some of the connector plugs (being careful not to break anything), at least if you break something, it is on the bad control board anyway which is being discarded.
