How to troubleshoot a Laboga Mr.Hector that doesn’t work, when LED diodes aren’t lit?
If your Laboga Amplifier isn’t working, and the LED diodes and control light are off, check if the main fuse is blown or if the power supply cord is damaged. Try using a different power cord. If the issue persists, contact Laboga service personnel or a Laboga retailer.
