I went to raise my top.It did not respond.It said "Roof Failure. See Manual" on 2007 Volvo C70

The manual said "Hold the 'top up' button for several seconds and do not release until top is completely up and locked." It went up without a problem. The manual says "Do not lower roof until roof is serviced." I am a retired auto mechanic, and I'm tempted to lower the roof in order to look for possible problems or areas that may need lube? Has anyone had experience with solving this problem? Thanks.
