  • what are these for???

    i think my inverter is bad, but i don't know how to test it.....

    those are possibly secondary input connectors, or audio in and out connectors.
    What maeks you suspect a bad inverter?
    you will need an ohm meter capable of 1000v+ ac to test the output of the inverter. note, this is AC voltage, not DC. use extreme caution, or refer to someone qualified to diagnose for you if you are not comfortable with high AC voltage.

        motorcity why exactly would you need a multimeter which measures 1000v+ ac?

          Because the inverter outputs ~1000VAC.

          But you could just use a multimeter to confirm that the inputs to the inverter are OK. If you find the inputs are OK, but the inverter still isn't functioning correctly, you could infer that the inverter or CCFL is bad.

          But it's my understanding that the CCFL is more likely to fail than the inverter. So, without measuring the inverter's output, you can only guess at which component to replace.

            well i'm getting 12 or so volts going into the inverter and nothing coming out....so I think it is fried....we'll see..i have one coming in the mail today...i'll let you know...

              there is normally a fuse on Xenarc inverters. Up near the inputs. looks like a resistor or diode but will be labelled FXXX

                  For a fuse, check for continuity.

                      continuity is good on the new inverter, but still nothing on the screen.....i know the screen is good because i tested it on my 700Y controller board....i'm thinking it's something on the controller board...

                        could you take some closer pictures of the invreter in high resolution ? in order to see if a composant is died.

                            I'm sorry but there is no way that it outputs 1000 volts AC. Maybe more towards 110/120.

                              Do you have any info on the inverter? Specifically the pinout?

                              Besides power and ground, your inverter may have a "sleep" signal. Meaning that there needs to be a voltage there to tell the inverter to turn on.
