Incorrect Battery voltage

[newmi]

Hello,
Recently I've repaired a turnigy 9x,it was broken to reverse polarity. I changed internal diode, and works correctly except for one thing. The battery voltage is incorrect. Max voltage appear in the screen is 2V/ 2.1V. I only can change the value down range (0.1V-2.1V).
I thing this is for the internal voltage divider, but i dont see any burn resistor, or any component.

Does anyone have any idea?
Thanks and sorry for my english.

hello, I spend exactly the same. Burn the radio, and repair. But now it shows 1.1V battery.

I have the V2 fimware original. As fixed it yours?

Thanks for the help, I can not find info on the internet.

Sorry for the English, I speak Spanish.


Appreciate it your help, I'm frustrated because I can not find the problem.

Unless you have upgraded to er9x firmware you are stuck with the original voltage reading.

I know, but right now I do not have the USB adapter to install your flash Er9x.

Anyway, I think there might be something wrong with the splitter voltje, and while installing the new flash, I will have a measure wrong.

I have measured the two resistors, voltage divider and give me 5.1K and 2.7K correctly.

Someone knows that another component may be failing, and gives me bad measure?

thanks

OK, the problem was stupid. When removing the condenser, cut a copper track (12V), and there was never voltage to the voltage divider, which is between the resistance of 5.1K and 2.7. Therefore the micro, had not as knowing the battery voltage.

I attach a photo explanation. (in Spanish)
