Martin Logan Purity - Light goes from Blue to Red continuously - I need help

[majin tcz]

I need help.

One of my Purity's signal light is switching from red to blue (mostly red) continuously. While its red I can hear a very low volume of whatever signal I send to it. Then it will switch to blue and get a full volume regular signal, then after like 10-15 seconds switch back to red.

Any help would be appreciated.

Hola majin tcz,

It looks that you have a power supply problem. For better service for the Purity model, contact Martin Logan service dept. At the power supply, there is the Bang and Olufsen digital power amplifier. This unit could be the culprit too. This model is easy to service. Just follow the Martin Logan service steps to find the cause of the problem.

Happy listening!
