Well, I've found another remote, which worked without any issue. So no problem on the receiver side.

Yes, harmony remote doesn't have a feedback.
I monitored today the activity on the spi interface between the transceiver and the mcu. Sometimes you can see some activity after a key press, sometimes not.
Could not find a system behind it.
I'll try to find another remote for testing....Leave a comment:

I would still expect some output on the display. The RC behaves erratic, thus I asked about a known working firmware dump for testing.
I don't have another original remote, but with my harmony elite I can control the main unit without a problem.Leave a comment:

You mean the push button itself?...Leave a comment:

Yes, after removing the white foil I tested all keys - they are all NO and closing every single one of them causes a wake up. The current draw looks fine for me - about 5 ma on start up, about 3 ma when awake and almost zero when asleep.
I noticed another strange behavior. There a light switch on the buttom side, which turns on LED Backlight of the keypad and also wakes up the MCU. This wakeup works always, the LEDs however sometimes don't react.Leave a comment:

Im monitoring the current draw with the lab psu and in addition the mcu sleep/awake state with thermal imaging....Leave a comment:

Unfortunately, this didn't have any effect. All contacts are clean and open. Still the same behavior.Leave a comment:

Thanks, I will try it tomorrow. I actually tested the frequently used keys and the reaction of the MCU (wake up) was adequate, but I didn't check all of them. I hope I'll get this white stuff off without damaging it.Leave a comment:

This was me, adding a cap in parallel for testing. Doesn't look that bad in reality...

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

well, it's completely disassembled now, there were no loose parts inside What kind of noise do you mean?...

Bose Lifestyle 650 remote malfunction
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...
No activity results to display
