One Tube stopped working
Update: I took out the defective LED Board and plugged it direclty into the controller. All LEDs on the board light up blue, exept for one which is red... Ive alsy ruled out that its one of the wire bridges by switching them round. Its always the last LED board in the chain that does not work if connected to the others.
any ideas what to do if one of the 4 tubes has stopped working?
