Every CCFL I have seen so far has one thick colored wire (pink or blue) and one thin wire (black or white). What does this color code indicate? Some of the plugs/sockets are keyed, but others are not and so the wire with the thicker insulation can go in on either side. Is it that one side of the output of these inverters is near or at ground, and the other is at the full voltage, with the thicker insulation on the higher voltage side? That would make sense, but why then are not the sockets keyed, or even marked, so that the high voltage wire would be relaibly plugged into the high voltage side of the socket?

A good practice is to note which wire went to each connector as you disassemble the inverter. Someone who looks at a monitor I have repaired might notice 'pink' or 'blue' written in pencil near each socket.

Re: CCFL thick and thin wires
Originally posted by PlainBillThe thicker wire is more heavily insulated. It can carry 1000 volts or more. The thinner wire is the return line, and carries less than 10 volts.
I do note the positions of the plugs before disassembly - but that won't tell me if the thing was wired backwards at the factory.Comment
