[QUOTE="Burt, post: 845199, member: 68616"] The only difference between an open and short (or closed) circuit is that, like in Tommy case, when the short occurs the camera automatically turn the power off temporarily to the monitor to prevent the frying of the board.. An intermittent open circuit would not require the camera to be turned off and on again to reset the mosfet... With an open circuit, you normally would only get the flickering of the screen without the need to turn the camera on and off.. Another example of an open circuit is when you take the lens off without turning the power off on the camera... When you put the other lens on, the camera does not need to be turned off and on again, because it was just an open circuit you created by removing the lens.. For a short circuit to happen, there has to be some voltage (Positive) touching the frame (Negative), hence the name short circuit... If Tommy said that the screen comes on and off [B][I]without the need to turn the camera off and then on again[/I][/B], then yes, it would definitely be an open circuit.. If you use/move the monitor often, it pays to check for any dirt/dust especially in the middle of the mount where the ribbon is forced to slide against the metal frame... A tiny drop of silicon spray could help, but as usual the best cure is prevention.. [/QUOTE]
