Hello,

my Einstein 640 doesn't turn on anymore.
Can you tell me how to check if the fuse is ok ?

Thank you,
teikidev.

The fuse is on the back panel of the light, behind a screw on clear plastic cap. Unscrew the cap, and pull straight out on the fuse (which is a reddish-brown color). If you or someone you know has a multimeter, you can check for continuity from one lead to the other. Otherwise, you can try the spare fuse that came with the light.

I tried the spare fuse but nothing changed. Still down... :(

Is there anything else to check ? Or maybe a combination of buttons to restart the unit ?

No button combination will turn the unit back on. If you know you are using a good power souce with a good power cord, then the unit will need to be sent in for service.
