Camera lost power mid-flight

[Socaljj]

Went flying today all was well for the first 5 minutes then I lost power to camera. landed safely as the rest of drone worked well. I tried power of then on to no avail. I searched these forums for a pin out of the hot shoe so I can start troubleshooting. I know one was posted here but for the life of me I can not find it.

It would be greatly appreciated if someone would point me in the right direction to find it.

thanks

I guess you can spend time checking other things first, but given the power failure occurred during flight, the problem is probably a blown fuse, commonly referred to as the "K" fuse. That will be discussed in Step 3.

1.) Check the Hotshoe. The "power" is battery voltage. If it has normal voltage, then it's a camera issue. DO NOT make contact between Power and PWM. That will instantly result in the need for a new mainboard. Given the consequences of a minor error here, you may just want to skip this step. OR, If you have another CGo3 or CG03+, you can just mount the other camera to see if you have voltage.


2.) If no voltage, dismount the hotshoe and ensure it is plugged in.

3.) If the hotshoe is plugged in and still no voltage, remove the Typhoon H top shell and check the camera connector and the K fuse.
The camera connector is the one right in front of the fuse.
The fuse will LOOK perfect. You have to check it with a multimeter.



4.) The fuse in this link is what I used to replace mine. No problems so far. The only place I found the EXACT fuse was a vendor in China, with a three month estimated delivery.

Thanks since garage (work area) is 100 degrees now will check first thing in AM

Is the OP in US? The eBay seller doesn't ship to Europe. Can't see why it's only a fuse.

100% sure is the K fuse. Watch this

Checked the power to the shoe 0 volts. Checked continuity of the k fuse dead open. Ordered K fuse to replace.

Thanks for the help

So this is a rare item?

Probably not to someone more familiar with this stuff. I had a hard time figuring out what I was looking for. I still don't know how "fast" the original fuse is.

It would be of great value if someone can provide the specification and a source for the original fuse.

This is the partial information I have:
1.5 amp SMD fuse, US size 1206, Metric Size 3216

UPDATE: Got the fuse (golly it is small) and now have power to the shoe...BUT... no joy as the camera is still dead. Now to search on camera fixing.

Thanks for all who helped it was very useful.

Did your slip ring cable is still intact? I will check that first for the continuity for each cable sometimes when you look at them look like they are OK but you can't see inside the cable. I always use a multimeter on ohm position to check the continuity.

Once I verified that the fuse replacement was successful I knew I was past my comfort zone. So I went to :
