Hello,
The main board on MA500VZ has 3 warning lights for each channel. The light that is lit in the picture is the output fault indicator light. This means that there is a hard fault or short some where on the channel 2 output module. This needs to br removed to check for shorted output transistors or open components.
Thank you for your advice, I take it you ment channel 1 though as channel two is working fine
