I'd like to sign up to the dead Unitiserve Society, but at least my tale of woe has a happy ending.
About three years ago my US died from the dreaded blinking logo disease. After switching off (in the correct manner) then switching on you get the usual blinking logo but it continues to blink - for ever and never stops, a bit like the last twitches of a favourite pet before it goes to meet its maker. Anyway it was under warranty from memory and the good doctors at Naim brought my faithful US back to life.
About 18 months ago my trusty(?) US died again - if it is possible to die twice. Off it went to the Naim specialist who, after some careful diagnosis, furnished the appropriate treatment and it came back full of beans. This time however no free NHS treatment, there followed a not unreasonable bill. All was well for 5 months then the wretched US died yet again, yes three deaths. Back to the Naim specialist, yet another cure administered and all was well again. My eventual contentment was however shattered when my dealer said he had received another bill from Naim for this further bout of private treatment. Before I blew a fuse, the dealer informed me that he had advised Naim that charging twice for a cure that should last a little more than 5 months might not be ethical. Thankfully Naim agreed and we all lived happily ever after.
My faithful old US has since behaved impeccably and I was informed that Naim had ironed out a couple of hardware issues in the course of treatment. So I am happy to stick with the US so long as it doesn't catch some other dreadful disease and become poorly again.
I was beginning to think that the US was a bit of a hypercondriac, but it appears to have gained a new lease of life. (Bugger, I shouldn't have said that, tempting fate and all!).
