    CCFL Wiring and polarity

    This might sound like a silly question but,
    On a ccfl tube or bulb there is a hot wire and a return wire. On my observation the hot wire is usually a bigger wire {smaller gauge} than the return wire; sometimes they may be the same gauge.
    If the gauge of the wire is the same the wire that’s pink or blue will be hooked up to the hot side .
    There have been questions ask “I didn’t mark the position of the ccfl wires when I unhooked them from the inverter what should l I do?”Well I haven’t seen a monitor that has different length ccfl tubes, the connectors are polarized so it shouldn’t make a difference, the larger wire is going to be hooked the hot side of the connector, And the smaller wire to the return side.
    Silly part,
    I f a used ccfl is used to replace a defective one, And the original polarity is not kept the same, where the wires are soldered to the ccfl bulb, do the gasses or electrons are whatever is inside the used ccfl, really care if they are moving right to left or left to right[develop any type of memory?]
    Well after thinking and rereading my question I am thinking it would not make a difference, if there is any similarity between a ccfl bulb and a florescent light bulb that is used in a house, the florescent bulb will work any way it’s installed in the fixture.
    I am talking about how the wires are solderd to the ccfl not at the conector.
    Or is the inverter circuitry more sensitive that it could make a difference?

    Whatever I do, I consider it a success, if in the end I am breathing, seeing, feeling and hearing!

    Since the CCFL is driven with an AC signal, there is no net movement of electrons in one direction or the other.

    For a number of reasons, both health and personal, I will no longer be active on this board. Any PMs asking for assistance will be ignored.

    Never be afraid to try something new. Remember, amateurs built the ark. Professionals built the Titanic.

      Thicker wire is High voltage
      Thin wire is ground.

      There is no difference how you turn CFL

      Problem would arise if you changed the wires in connector. Ground wire is not meant to sustain such high voltages and would arc to any nearby ground.

        HANNSG Hi221 -- 2 secs to black feat. CCFL flicker & "burn" marks on power board
        by ttmi100x
        Greetings everyone,


        I have a HANNSG Hi221 monitor that exhibits two seconds to black issues (backlight goes off, display is still on as confirmed by shining a flashlight on it) with some additional oddities...


        The monitor failed on me with a standard "2 seconds to black" some time ago prompting me to initially replace most of the electrolytic capacitors (some of them were bulging/leaking).
        Things kinda sorta worked for a night, then the problem returned along with some flickering and "buzzing" noises.

        Upon closer inspection...

        TOSHIBA DLP 52HM95 How to reset timer module on bulb
        by repair-it
        I replaced the bulb only on my Toshiba DLP The bulb is a TB-25. This is the first time I've done a bulb only replacement. Supposedly there is a timer module that needs to be re-calibrated or reset. I don't know where the module is located. I see some vendors selling the bulb with the housing stating module included which leads me to think the module is located inside the enclosure the bulb mounts in, but I didn't see it. Maybe it's inside the plug attached to the bulb?

        Anyway - I am seeking information on how to reset this so called module so that the lamp will operate. Apparently...

        LUMIMAN Smart Bulb IC ID?
        by ezenia
        Hi,

        I have a LUMIMAN Smart Bulb that suddenly stopped lighting one day. The bulb is still detected in the app, but won't light. I've probed around and nothing seems to look off with any of the diodes, caps or resistors. The Bluetooth/Wi-Fi module seems to be working as it's still detected in the app. I even tried deleting and re-pairing the bulb (it didn't light, but I was still able to follow the pairing instructions), it re-paired fine, but still no light.

        In diode mode, the LEDs all light up when probed so I'm guessing this means the LEDs themselves are OK. I was expecting...

        New wire for my RDE3340 Whirlpool electric range
        by wnlewis
        OK. I got the rocker switch figured out thanks to the good advice on this forum.

        Now I need to figure out the correct wire to go to the switch from the broiler element and from the oven element.

        This is a Whirlpool RDE3340 electric range.

        The common wire on the switch appears to have a high temperature insulating material. I am guessing that both the wire to the broiler and the wire to the oven elements also need relatively high temperature insulation. What do I need to look for? The broiler is rated at about 2400 watts.

        Where may I find parts...

        Help on Samsung Syncmaster T220 dead ccfl lamp
        by mikey5791
        Hi,

        This monitor previously is my main working monitor which i have been using for 8~9 years. Yesterday, when i switched on my pc from fresh to power on, the monitor is just black no display. I started dismantle to look inside the monitor power board but nothing looks suspicious or burnt. So i took my external ccfl inverter to try to power the monitor ccfl lamps which consisted of 2 lamps on upper part and 2 lamps on the lower part.

        Found out the upper ccfl lamp which is supposed to connect to cn304 on the power board did not light up. Then i installed a used working...
