Cerbo does not boot anymore.


Hi,


I have two systems with a Cerbo GX and both died in the last few weeks.

On both systems is connected:
- Multiplus via VE.Bus
- GX Touch
- BlueSolar via VE.Direct


When I disconnect everything, the cerbo's still don't boot.
A week later, I tried powering them up again and one of them did. 10min later it died again.
When I opened it up I saw that the small CR2032 battery holder came off.
In the second one, that is not the case so that cannot be the main problem.

On the pictures you show I can see blown components. But also moisture marks. So maybe you are having condensation issues where they are installed.

Yes I agree with Alexandra - there is definitely water entry as you can see the drop marks on the shield cover plus the board has corrosion damage - try cleaning the board , especially were the multi connectors are and you maybe lucky that its just a small short between those two soldered connections - otherwise it will be a bin job I would think.
