No, it's a different case here. The antenna is just a trace on the pcb. All keys seem to react.

Hi everyone,

I'm trying to fix this RF Bose remote (model nr. 420129) for a friend. After applying supply voltage the display shows the Bose logo, after a short period of time it goes dark and the MCU enters a sleep mode. It wakes up after a key is pressed, the display remains dark all the time after the start up sequence.

Sometimes it can still be paired with the main unit and you can control it for a short period of time, then the unit stops reacting again.

The pcb is clean, there are no signs of corrosion. The voltages look adequate.

I read the dump from the nvram and rewrote it several times without errors, but the problem remains.

Maybe anyone has a working dump I could try? Or other ideas I could do?

Thanks,
Michael
