    I’m stumped. 2 issues.

    1). When I’m in single lamp test mode, the DMD is reading “g” should be blinking, but “t” is blinking? See pic

    2). Three of the letters in “* T H I N G *” flash/work. Three do not come on at all. I’ve:
    -Checked the power at the connection at each socket and it is getting power
    -changed out the sockets
    -changed out the bulbs

    No dice.

    Thoughts? Thanks for your help.

    1. Is the board reversed? What happens when you go to test “T”?

    2. Reflow the header pins on that board. They’re likely cold.

    Looks and sounds like connector is reversed.
    Reverse connector on thing lamp broad first.
    Or, connector could be reversed at power driver board. Check lamp board first.
