I took this receiver to their shop on 21 June and was told they would be able to diagnose the problem by Mon. or the next Mon. I called in early July and was told someone was actually looking at it now and they would call me. Today, 15 July, I went into the shop and was told the parts to fix it "might" cost around $200. They told me it would work "intermittently". As soon as I plugged in the receiver, the same warning light came on immediately. Now the receiver will not power off. Would not recommend this business based on my experience.
