taranis have problem power with external modul

[Lincon]

Hello everyone,,,

i have problem with taranis x9d plus . I tried use a external modul OPenLRS , but seem taranis have not output power . I also try flash firmware for RX XSR but it can not work . I check by VOM volt , it is zero . All connect is exactly

So anyone same my problem ? i use Opentx 2.2 . who know check component on mainboard ?

Have a look on the back board. The power is switched by the P-channel MOSFET Q2. The gate of this is switched by the n-channel MOSFET Q1, with the gate of this driven by a signal (active high) that passes through R2.

any idea what i could do to get signal back on my taranis x9d signal pin in the module bay? its supose to read aprox 0.3 volts with a meter but i have 0 volts .
the vcc pin, that is the middle pin of 5 pins total that are back there is showing battery power but i cant flash firmware to any receivers and my r9m dosn't work either.

thanks jeff
