Hi,
I am new and hope someone could help me out with my problem. I bought for curiosity a faulty Flir One Pro (USB-C). The device shows no operation at all, no lights after trying to switch on neither a light after plugging in the charging cable. So I opened the device an checked battery voltage. It was just 3.2 volts. I charged it up with an external charger and tried it again.
Unfortunately this doesn't helped. If I plug in the charging cable I just get ~50 mA. When I hold down the power button for several seconds it jumps up to around ~370mA. But that's it! Nothing more. Maybe someone has experience with this device and could give me some ideas for more debugging?
Maybe the suspect is the BQ24295 chip? While holding down the power button and getting around 400mA the chip gets warmer, not sure if it could prevent the device from turning on?
Thanks for any help in advance!

It is unfortunately in russian, but it seems to be a similar issue. Maybe someone knows, what they have exactly done?

I understand russian.
he has 2 units, 1 working another not working. no power.
he did nothing good here on non working unit. he tried to find the cause, but no success.
later he just done another job on good unit to resolder cpu.

Flir One can - and will - die with vastly different symptoms. Some are easy to fix (re-connect battery, replace battery, ...), the others are non-trivial and likely end up requiring reballing.
With what you're seeing, there's a decent chance that the CPU attempts to boot, so you should serial output. Can you check that?
