[Elphel-support] elphel NC353L-12V Kit defect

[Olga Filippova]

Hello Viatcheslav,

We can send the new 10353 board to you, if you think you can disassemble the
camera and replace the board. In this case please ship us back the 10353
board, so we can test it and find the problem.
The other option would be to ship the camera back to Elphel, and we will
replace the board here.

Best Regards,

Olga S Filippova
