They actually did. I replaced thousands of these phones (at no cost from NEC) for our customers as well as other vendors. At this point you are talking about a system that has been EOL for what 15 years now? I would also make sure they didn't inadvertently turn the contrast all the way down. From what I was told it's the connector or connecting cable that goes bad. BTW, the super-display phones never had this issue.
