Default Re: Inverter tester using old CFL

There is no polarity on the lamp connections to the board, as long as the wires are connected to the two pins of the socket that will be fine. This inverter board is for the TV so the ground return is on the small connector at the bottom right in the pictures, the two pin on the white connectors are for two lamps. If you look at the spec sheet of the panel, it will show how the lamps are arranged inside the panel.
