Talk about good timing - one of the Sleep Number bed displays started to loose LCD segments while we are at the GNR. This is good news since the bed manufacturer was one of the vendors attending GNR.
When I told the guy what our display was doing, he gave me a new unit (you cannot just replace one part of the system - you get a new air pump and controls.) He said they were having some problems with the displays in the RV environment so it was redesigned a little with surge protection for the display.
Here is
a link to how I changed mine out.
