You should NEVER try any non standard power adaptor on a camcorder even in an emergency, as camcorder electronics are super sensitive to incorrect voltages which may also have RAW unstabilised & unsmoothed DC, as can be had from some supplies used to power portable radios / tape machines or some CD's. However IF it stopped working when you removed the supply then there is a slight chance that it will start again when a "properly charged" battery is installed, so unless you try that it cant be taken for granted that the internal fuse has blown. (IF you are lucky and have not damaged the logic circuitry)
