Used wrong plug on my camcorder!! hELp!!
I accidentally used the wrong power plug for my camcorder. Nothing
happened. It didn't power on or anything. I didn't think much about it. Then I figured i might have had the wrong plug. When I finally did find the right plug for it, I plugged it in and nothing happened. It doesn't turn on, nothing. It was working before I plugged in the wrong plug. The power adapter it is supposed to take is an 11v plug. The one I accidentally used is a 9v. Did I blow a board or something? Is this irreversible? |

The only way I would think that it could damage it from plugging a 9v power
supply into a 11v camcorder would be if the polarity was backwards on the 9v psu. Check the labeling on the transformers and see if they both the same polarity.

As others have said, if it was just 9 versus 11 volts, no damage should have
resulted. If you of them had positive and negative reversed, then you quite likely blew a fuse or a voltage regulator chip. The fuse may be super-miniaturized and hard to recognize. If I were asked to repair it, I'd start with the first few components right inside the power inlet. Also... Try it again. Are you sure your 11-volt (correct) power supply is actually working? |

Or if it was an unregulated 9V wall wart which in reality puts our a much higher voltage than 9V. Dave |

And this is the reason I bought a cheap etching tool. Every wall wart, and power supply in the house gets the item name and model # etched onto the back of the power supply as soon as it comes out of the box. It really helps when all it says on the back of the power supply is voltage, and made in china. |

Besides the obvious danger to equipment, this is IMO a safety issue. Sure the chances of something burning up and perhaps causing a fire is remote, but it exists. This is one of my pet peeves. I wonder how much gear gets trashed every day because of this? Power plugs should be standardized so that 'one size' *doesn't* 'fit all'.... jak |

day because of this? Power plugs should be standardized so that 'one size' *doesn't* 'fit all'.... I agree! Amateur astronomers often have Meade telescopes and SBIG CCD cameras. Both run on 12 volts, a couple of amps. They take the same power connector. With reverse polarities. The SBIG gear has reverse polarity protection. The Meade gear blows a fuse and (if it's an early model LX200) explodes a capacitor which is upstream from the fuse. |
