Camera, A/V Tx, no image in goggles?


Very new at this, probably a simple fix or compatibility problem: Lumenier CU-690 Ultra WDR camera using separate 12VDC power source, connected to Immersion RC 5.8 GHz A/V Tx (tried power at 7.4V and 11.1V), red Tx light on, but no reception at FatShark HD goggles. Tested goggles with same Tx on different model, goggles work fine. Tried all 7 channels on goggles and 2 different channels on Tx. Connected powered camera to video monitor, monitor said "no signal" (bad camera?), will be able to test Tx with different camera tomorrow. Any other ideas for tests? Or go ahead and tell me I'm making a dumb newbie mistake somewhere. Equipment used at links below. Thanks.

If you have{OSD} on screen display,It will need to be powered up also.
I have been told that the system should be powered up in this order,VD TX,Quad if you have OSD,VD RX,then goggles,this is only here say.
I will be going out to the field at 5:30 tomorrow,you are welcome to come out,
and we can try to trouble shoot with me FPV set up.
Also the switch on the bottom left off the goggles might need changed?
Or give me a call,I think you have my # from the text I have sent you.

Thanks Dennis. I think I have this one resolved, but will call you with a couple of other questions. Robin.

Does anyone know a good source for the small, 3 and 4 pin connectors with leads that plug into board cameras like the Sony Super HAD CCD 600TVL? I'm running the camera through a filter that uses the same connectors and need a few more. Thanks.

They may be called 'molex picoblade', or 1.25mm JST. I looked up the camera and getfpv suggested it's a '1.25 mm 3 pin cable', which google images suggests is the molex picoblade.

Here are a few links that may or may not help:
Cheap plugs if you want to crimp your own.
An ebay auction, ~$6.50 for 10 of them.

These look right to me, but you should check to make sure they match what you expect them to look like.

Thanks for the links. I had found the Hanson Hobbies source you listed, but just wasn't sure if that was what I needed. I ordered several options of 3 and 4 pin connectors with leads on the eBay link, so hopefully I'll get what I need. I'll have plenty of extras, so if anyone needs one, just let me know, glad to pass them on to others.
