Plumber

I'm looking for IR boards for my SDI HD out door security cam...actually cams. I need 6, which have failed in the last 2 years. They do not power up anymore. They really do not have a known name. They are form China. Although I'm a plumber, I know that I can repair these cameras should I get the boards. I have pictures of the boards, the cams, and even the box that they came in. Does anyone here know where one might pick them up? thanks.

Well, I guess nobody knows the answer to that one.
