Aquarite Gold line, only power light comes on

Aquartie Gold LIne r1.40 board

Curious if you have ever run into a situation wherin only the power light comes on, the display cycles ,and what issue may be.

i can change between metric and readings but the display is set on AL-5 wont allow for the AL setting to be changed? I have a video up here: https://youtu.be/EEG1usx2Yno
