Re: 9xr Pro not power on problem.

The resistor is 47 Ohm, parallelled with capacitor. Fixed that couple as well. Hopefully this will keep the device alive for a while... Thanks
PS attached the photo with c79 circled, for future reference. I'm not sure why it is coupled with a resistor, but it is.

Re: 9xr Pro not power on problem.

Yep, of course, it was my ohmmeter which is not sensitive enough. However, the problems are still there. It doesn't want to turn on again. C79 is fried, probably the current from power source went too high. Could you please share its value as well? And looks like C79 also has (uh, had...) a resistor...

Re: 9xr Pro not power on problem.

Thanks Mike
Good news that ended up with desoldering R9. Although the readings on R9 itself were as fine as 0 Ohm, the traces were disconnected. Fixed.
Sorry for hesitating :|

Re: 9xr Pro not power on problem.

Hello guys, probably you could help with my case as well. I accidentally shorted PPM1 pins (antenna/ground/bat+), so 9xr pro won't turn on now. Voltage at bat+ pin is around 2.50v; R9 is ok, C1 and C4 broken (my fault, now not sure what the values are to replace). What else should be checked, any id...
