burnt fuse on boscam transmitter?

Is this a burnt fuse on this thing? I'm pretty certain I had it wired correctly. Is it true boscam has the red and black wires switched? Could anybody point me in the direction of the correct wiring diagram? This is what I'm tracking as of now.

Yellow to yellow (video)
Red to white (audio) not necessary
Brown to black (ground)
Correct?
Looking to use the replacement one I just ordered on my gopro black.

I don't know if that's a burnt fuse but I have that same vtx and that red and black wires are correctly labeled as in your 2nd pic.

I also run it off the balance plugs of a 3S battery with no issues, barely gets hot, just a bit warm.

Would running it off of a xt60 cause this? I've seen it done before. I've also seen this burnt exactly like this as well.

Have the same problem. My problem was that i connected Mobius Action Cam power input into Tx video in.

Now everything works but cant powersupply camera through Tx. Would be nice to know how to repair it, because it cost quite a lot.

Quite common to happen when there is a polarity inversion.

What TX is that is it the 400mW? I only have the 500mW and 200mW to check the parts.

So you put the cameras positive lead power supply in the transmitters video in? Camera red wire to transmitter yellow?

I don't think the type of battery plug has anything to do with it as long as the polarity is correct.

I'm confused, isn't that what I said? And on yours, you can still transmit, just not power anything? How did you test it. I'm afraid to hook anything up to this.

What part is it that was damaged? Find out the values of it and replace it.

I also had one burn up like that, not sure what the problem is with these tx. I know I had it correctly wired as I have two others. Just more wasted money

Hi there, I did wire my mobius to ts353 with an hobbyking osd ..
Did not check the polarity is reversed for the ts353 supply .. It did an electric spark as soon a I plugged the battery balance to the fat shark regulator ..

Then I soldered to swap the polarities .. but the ts353 don't seem to work properly : no red led on, the output of fatshark balancer is still 11.4 V ..

I'm kinda lost .. do anyone have a clue how to solve / repair this ?
Thanks
