The minimum value that justifies repair keeps going up, and probably exceeds the vaule of the unit. In the meantime, "repair" is getting replaced by "replace" even under warranty. Do check to make sure that you are not dealing with a
power or connection problem, which you can chase down yourself with a multimeter. If all the connections are good, and
power is there, then you may best replace it.
An electronic device that is totally not working - dead - is actually better news than one that is partially functioning. The partial definitely needs repair, while the total stoppage may be a bad connection.
I had an interesting example of the repair/replace shift here a few weeks ago. Beautiful french door
refrigerator, under warranty. The dealer chose to replace the whole thing, over $1,400 worth, rather than repair the ice maker....
