You've probably blown a diode or fuse of some sort.
Cam manufacturers are notorious for not providing any kind of circuit
protection except for a diode fuse or some sort of solid state fuse
protection at the intial path on the board.
If you are proficient at circuit analysis and repair you can usually
do a visual trace and find the culprit.
They do make every effort to hide it though and with the
miniturization on most small hand held DV cams it might be a trick to
find it.
An honest repair shop will do the repair for a not unreasonable price.

cheers I opend the unit up and found what looks like a small smounted black
diode?? very small with three little legs 1 from the top and 2 from the
bottom
I dont know what it is but it has a bubble mark due to heat. I can just make
out some number I think its says on it 352A?
I havent a clue what the component was more or less next to the power
input..


Cheers Ray

You said it has a heat blister, so it almost certainly needs to be
replaced. With any luck it took the brunt of the reverse polarity and
there is no further damage...

digikey.com and mouser.com both have this part listed, but with long
lead times - not sure where you might get one soon, perhaps someone else
can help.
