    Hello guys
    I have been flying with my phantom for 8 months.My setup is;
    PHANTOM 1
    PMU V2
    DJI MINI IOSD
    FATSHARK ATTITUDE 250 MW FPV SYSTEM

    Yesterday, i tried to fly with 2 parallel battery for the first time.
    As i powered, the phantom played abnormal voltage sound and i cut the power in a second.
    After i tried to fly, Everything is normal but dji mini iosd dissapears as i increase the throttle!!!!!!
    Video signal is working 1KM but no iosd.As soon as i land iosd comes back????

    1-I disconnect GOPRO mini iosd works in the air like it used to be i can see via fatsharks(NO VIDEO-YES IOSD)
    2- if i connect them properly it works only at Motor start(idle).Little increase iosd starts to blink and eventually off.
    3- First time i tried to connect mini iosd to pc(iosd software) via micro usb cable(samsung cell phones) it did not connect to pc?????????
    Which part should i replace?
    -PMU V2?
    -Mini iosd
    -mini iosd cable/gopro av cable
    -something with fatshark?

    By the way i powered the fatshark rx via balance cable with double battery(may damage the av cable somehow)

    Thank you guys
