I am using an eachine tx5258 with its original antenna (I ordered better ones, they haven't come yet). I have not flown my drone yet. Whenever I plug in the battery the VTX and my monitor are connected, This is evident because the screen goes from static to black. A few seconds after plugging in the battery each time the display on the VTX which states info about channels fizzles out, and the monitor screen turns to static. The VTX each time becomes extremely hot, I've also noticed that it stays on longer the first time I plug it in. It was not an expensive VTX, so I have no problem buying a new one. But I would like to figure out whats wrong with it. There are other problems, like no OSD and no video, but It is difficult to troubleshoot those problems with a VTX that doesn't stay connected.
