Useful article thanks.
Your make the comment “Okay, now it's test time. Combine the Yellow On/Off wire with the Black Vin Wire. That will be the positive connection, the Red wire is ground and will be the negative”. This comment has me a little confused.
I have the AVT2028 V4 dual-CCFL board (only one transformer on it, but two HV output ports). It has the same control cable as shown in your photos — the wires are red, unconnected, yellow, yellow, unconnected, black. The markings on the board are +12V, +12V, ON, unmarked, GND, GND.
I connected the red wire to +12V, black to GND, and the two yellow wires to +12V. I don’t have the correct connectors for the CCFLs so I soldered onto the sides of the CCFL connectors and took each pair of leads to each end of two standard T5 fluorescent tubes (so using them in CCFL mode).
No joy. Any ideas?
