Hint needed: Taranis X9D plus EU pre 2019 starts only after unplugging external battery

Post by dkasteli »

Hi,
I have Taranis X9D plus pre 2019 version. I did not use it for few years. It was stored in garage. Few time a year temperature was below -5 degrees Celsius.

I tried to start device. Withiut success. After that I replaced external 2000 mAh batters. I also replaced internal CR1220 battery with new one.

Now situation is like this: device starts up only aster unplugging/plugging external battery. After start I can shut it down by utilizing on/of slider. Display turns off. But I can not start it up again again without first disconnecting/reconnecting external battery.

To me it looks like shutdown did not finish correctly so system can't startup. Same situation is when SD card is present or notr.

I checked many things on internet and I'm running out of ideas. Maybe I'll replace board.

Ayn hint? What else could I try? Is it possible to connect to Taranis via terminal emulator to check logs of operating system (e.g embedded Linux)?

Any hint would be highly appreciated.

Thanks and regards
Darko
