Back up, reverse, rear view camera.

[Korisnik]

I'm interested if anyone had experience about this before. I had bought one on ebay and accidently switched polarity when I wanted to conect it on a battery. I have never manage to start it , to get the video (I've conected it properly and only thing I couldn't find is NTSC on this monitor, only PAL SECAM and some "n with numbers " type I found).
The question is did I burn it when I conected it (wrong) first time and if yes is there any kind of fuse in these cameras to prevent this happend?
Also there is a posibillity that it never worked (came like that).
Is there any solution for me to try to get video; or just to throw it into trash? Thanks.

Take it back to supplier.....

You followed all instructions and it wont work!

Must have been faulty when you picked it up!

Providing you bought it from an eBay Trader all your normal consumer rights apply. This is despite any terms and conditions to the contrary on their shop or sale pages which are unenforceable.
However, if you purchased the from a private seller, providing the goods were as described, caveat emptor (let the buyer beware) applies.

Yes. I have one dilema about this, could I make some problems (burn it), because I have switched (mixed) polarity when I have connected it first time (plus(camera) on batery minus and minus(camera) on bateries plus - it' 12v camera). If this caused any damadge than it is my fault, if this can't cause damage than it's not. Could I cause damage by switching the polarity? Thank you for your suggestions.

where are you ? you mention NTSC that is for US tv's in the uk we use PAL. i don't think it will work as ntsc if it is a pal camera.

I have switched polarity (mixed polarity) when I was conecting it first time, that is probably caused problem. I think that problem is solved. There is a small voltage satabiliser and two resistors betwen camera and 12 v battery source; camera should get 3.3 v with that stabiliser and I didn't got those 3.3 but 12v. It seems that one of those resistors is blown and stabiliser shows OK. when we measured it. We tried it without those resistors and couldn't get those 3.3 v. Problem could be a stabiliser too because there isn't anything else more (even if it's shows OK. when we measured it). It isn't worth of trying anything further(I didn't payed it that much), becasue i would have to get those spare parts and mess with it. It is NTSC cam and I had that system on the tv I have used to try it, it is written short on this tv as N4.43 an N 3.50(it is ntsc mark). Thanks for suggestions.
