Hi Michael,

The first thing to do is to remove the top panel and inspect the two fuses on the main amp board of the channel that is not working. You will probably find that one or both of these fuses are bad. Unfortunately when the 1080 starts blowing fuses it is usually an indication of other issues that will cause the fuses to blow again in time. That would probably require a trip to a service depot, unless you are handy with a soldering iron?

Thanks,

Andrew
