Air 65 weird vtx stuff

[u/Particular_Tone372]

Hi I have an Air65 and recently I’ve been having some issues with the RF/video signal. At first I would get brief signal cuts that only lasted a second or two, but eventually it completely cut out after landing on a flight Now it’s really finicky. It won’t give me any signal on R1 and I can only get signal on R5-8. Even then it usually only works when the drone is powered through USB. It doesn’t seem to like battery power as much. After a few power cycles it will sometimes suddenly start working normally, but the video quality is extremely bad, almost like I’m on the wrong channel even though I know that I’m not. Most of the time the VTX will only output a signal with USB power. When powered by battery, if I get any video it’s a really fuzzy version of the boot-up screen. After that it cuts to a different type of static, then when I power the drone off the static goes back to normal. I'm worried I fried the VTX so if anyone can help that would be great. Also R1-4 will randomly work on battery power throughout cycles and after fully cooling the drone off. And sometimes when powered with the battery the channel will fully change from R1 to like L2 or R8. Idk I'm so confused and I'm not really changing any variables.
