Good luck getting information from the OEM. |

Here is a webpage that can help http://kiloohm.info/smd4-resistor/ Any chance you can locate a similar unit and take a peek inside? J |

I assume that if they do, then it might cost a pretty penny as the camera unit itself is not cheap around here, but who knows, maybe I get lucky. It would obviously be much cheaper to just fix the current board, if at all possible. Regards, Jannie |

Also, even though I considered it, I wouldn't want to buy a unit, open it up just to peek and then put it back together again and return it ... just doesn't feel like the right thing to do. I'm also on the lookout locally for 2nd hand units, but it seems that people rarely sell the camera unit on it's own, it's usually the full intercom system. I might still get lucky, but time will tell. Regards, Jannie |
