简介

If your Abask A8 Dash Cam is not functioning properly and all other possible causes have been ruled out, it may be time to replace the motherboard. The motherboard connects the most important internal components of the dash cam and allows them to communicate with each other.

If a motherboard needs replacing, your dash cam will likely not work at all, failing to power on altogether. Follow this step-by-step guide to replace the motherboard and get the Abask A8 working like new.

Before you continue, please unplug the camera from its power source and hold the power button down for 10 seconds to avoid dispelling leftover energy. You may also wear an Anti-Static Wrist Strap to prevent electrostatic discharge.
