I have an Onkyo M504 Power amp. Some time ago one of the green lights (the left one) over the VDU meters packed up. It doesn't affect the performance of the amp, but I would like to get it burning again. Anyone any idea if this can be done by myself or is this a workshop job.

I read somewhere that these lights can be turned on and off but I can't find out where you can do this, I don't think this has anything to do with my particular problem but you never know.
