Hi Guys
We have a 2007 Autotrail tracker with the inbuilt entertainment system obserview CM-680_D with SV10.21rf monitor. the camera works ok and TV visual is working just no sound!! the dealer has said that for £100 they can change a diode, has any one had the same problem ? and is there a quick diy fix?. RS or other supplier and a wiring diagram? Regards Tony B.

1) Checked all the basics like cables not come loose, disconnected all the power from the Obserview box for a while to reset it, checked the batteries in the remote etc etc etc.
2) Used a digital multimeter to check that there was a 12V supply coming into the Obserview unit. Also to make sure that the isolator switch was working correctly. There was 12V going into the unit, so I could tick that box.
3) So from this I figured the problem must be one of the Obserview box itself, the screen, or the cabling between them.
4) I called Sargent Electrical who did the electrical installations for Autotrail, were helpful and in turn put me onto SCS Components - the company who did the A/V equipment and reversing camera etc for Autotrail back when my motorhome was built (2008). You can contact them on 01924 893656.
5) SCS were extremely helpful and gave me some guidance on where the fault may be via process of elimination, starting with the cheapest thing first! Initially they said that given there was 12V going into the Obserview box, that the fault could be in the Obserview unit itself. Thankfully they still supply these so I paid for one and they sent me one out in the post. It was easy to swap over and test. Sadly it didn't fix the issue!
6) Spoke to SCS again and this time they suggested the screen itself. The good news was that they also still supplied these but, sadly, they're not produced in large volumes anymore so the cost was a bit eye-watering (I think around £400). Anyway, they sent me one of these out, I plugged it in and bingo...we were back in business with a nice new screen. Taking the old one off is fairly straightforward, flip down the screen and just 4 screws to remove and one cable to disconnect/reconnect. Job done.
7) SCS offered to refund for the replacement Obserview unit but, given it was fairly cheap (I think around £50 from memory) I just decided to keep it just in case one day it also packs in!
