Thank you for the picture.

As I mentioned, I looked into it, and this is an ADC failure, or Analog to Digital Converter failure. As told to me by our EMEA support team for your area, we do not support such repair on end user level and if you are a certified service partner or bring it to one, they have access to documentation telling what the fault is and how to fix it.

Hi Umar - I don't know the information you're asking for (because we don't service them here in NAM, only replace) but you are trying to service this if you're looking at the logic board and have removed it already. The only advice I can offer is to seek out a service partner in your area to see if they know the answer to the question. If anyone else wants to help and reply, it will be at everyone's own risk as I cannot condone working on this if you're not a certified service partner.

Hello,

I have the exact issue.

Did you fixed it?

Once I had access to webpage, now I do not have anymore with new batteries...

It said that was ADC fault, and AC mains wore more than 400VAC, even with AC not connected...

Thanks
