I've now had four or five light rings fail on my Sweet Sixteen. At my most recent service (March 2013), my dealer replaced the connector piece and/or the wiring too on the advice of HQ, but only a few hours into using my machine again, yet another light ring has started flickering/strobing. She said if this one went, then she was stumped and something might have to be done to 'a board'. She's currently away so I can't call her. If I have to return my machine to her, it's another 3- to 4-hour round trip (the freight is WAY more expensive than the fuel to get to/from her dealership in the city).
This small part has cost me a lot of time and money -- in trips to/from Perth, in postage, in frustration at not being able to use my machine as intended, in time taken to swap out a light ring either by her or by me.
I love my machine and my dealer provides awesome support and service, but I'm thwarted at every turn by this darned light ring. I'm also not alone. Several members on the informal Yahoo! Group for the HQ_Sit_down_Model have reported light rings that have failed, but I'm the only one in that group who's had more than a couple fail.
What do I do next? Please don't suggest that I call HQ headquarters as I live in Western Australia and the time zones don't match.
If there was a faulty batch, has HQ changed their supplier of these light rings? If so, how do I get one of the newer ones?
