Newby here. Ok, so I bought a Boscam FPV TX, iosd Mini and GS and following a very helpful YouTube video I got it all soldered in neatly and securely and working fine for one flight. Then, being a conscientious P2 owner I thought I would do a cycle on my battery. Of course I forgot to attach the antenna to my Boscam Tx, and promptly burnt it out. Bugger! I checked inside for damage and it appeared ok, and the P2 still flew fine. So thinking I had learnt a lesson, I ordered a new Immersionrc Tx (see where this is going?). After 2 long weeks of waiting, the carrier pigeon finally arrived with my part which I excitedly slap on and plug into the plugs I had soldered in for my Boscam. Being that they were the same...WRONG! Making sure I attached my antenna I powered up and was treated by a little flash and electrical smell. Not good. Too late I find a post on a forum about the reversed polarity and frantically rewire everything, but of course to no avail. End result: P2 that flys fine Iosd mini and GS getting power (green lights) Immersion rc TX no LED FPV obviously not working And most worryingly, this molten blob and scorching where the fpv/ iosd plugs into the P2 (hopefully shown in the attached pic). I'm guessing the blob used to be a diode or something! Anyway my questions are: Can that damage be repaired and if so how? Is my new FPV Tx likely stuffed? I am clearly not an electrical wizard, nor do I have any fancy testing or fixing equipment so please be kind and basic in your responses :mrgreen: UPDATE: Following my post I tried the other thing newbies never do to the frustration of regulars, and used the search function. I realised I am not unique in my predicament and tried the option of powering the fpv directly from the battery wires. This works but I am interested in what I have damaged and whether this is a safe solution?
