I suspect it's the tubes. As they get older they take a little longer to ionize when they've been off for a while. Shoot, some that I've bought in Ebay took a day before they would strike. Once they're running, although it is a multiplexed design there are always residual ions in the tube during the dark period, and often for hours afterward, so it should come up instantly after a short break.
