Trouble of Focus with V4 Miniscope

[alexis.fa...@gmail.com]

Hi,

Thank you for this amazing V4 tool.

I have an issue with Focus. With a V4 that we use for 2 years at least, everything was working fine, but now we suddenly loose the focus ability.

I have try to realigned the EWL ring with the lens, but I am not sure how it have to look like.

However, there is cement on the PCB going to EWL, it was working before but may be there is another issue.

I send you pictures.

Did you have an idea, or things that I need to test?

Thank you!

Alexis
