    I am trying to repair a LG W2452V monitor that I had lying around. It seems I am missing the cable going from the main board to the headphone-jack/control buttons boards. The connectors look like the one in the picture: they have 11 pins each and are both male. Does anyone have any idea what the name for this kind of cable is?

    P.S. I have been searching for a name for the past 2 hours and I hope it's not something obvious. connector image

    display - Why would I get an electric shock from a VGA cable connected to an LCD monitor?
  • CoffeeBean

    While arranging cables tonight to prepare to plant a new workstation, I got an electric shock from the VGA cable (that was hooked up to a seemingly good, yet older LCD monitor).

    Of course, when the monitor was powered off, it didn't happen, but when we plugged it back in, I got the same jolt, and decided to trade monitors before electrifying a brand new workstation.

    Does anyone know exactly what goes wrong inside an LCD monitor to cause this? I know older CRTs were shock-worthy, but I never expected it from newer technology.

    There's an electrical fault in the monitor. I hope it's under warranty.

    It is NOT the signal for the picture, which is extremely low voltage and high frequency and cannot be felt. It's probably a short in the monitor which has put real voltage on a cable meant only to carry a signal. Unplug it, leave it unplugged, and either get it fixed or dispose of it.

    Nothing to do with "new technology" here--the problem isn't in the technology, it's a wire making contact with the wrong part.

    but I never expected it from newer technology.

    Why not?

    Somehow the signals needs to be transferred from a to b, in order to do that they need energy of some sort. Electricity is the way to go..

    Wherever Electricity comes into play, there always is a chance to get shocked, however mild or severe.

    In order not to be shocked, Electricity need to run into the earth, thus the technical term "to ground". If you get shocked it's mostly due to faulty grounding.

    Faulty grounding results in YOU being the medium it (the electricity) needs to run into the ground (a complete circuit), thus shocking you.

    The shock is due to electrical signals (from the monitor) flowing through your body. The signal is always present(when monitor is on), just that it needs the circuit to be completed. Normally when you connect it to a workstation, the circuit is completed by the workstation. But when you hold it, its you who complete the circuit & hence the shock :).
