No, you weren't alone: my recent experience also suggested that the live departure boards were somehow blank!
Rather puzzled as to why I was just seeing a blank white space on my screen, I scrolled down - and found the actual departure board information, in a separate box below the other 'left and right hand' advertising boxes?
I suspect it's something to do with the inclusion of the platform information that John R flagged to us recently: the addition of one more column of information on the departure board view, as some PCs see it, seems to have caused the departure board itself to be 'squeezed' down to below the white space you may be seeing?
Sorry, I'm hopeless with the technical terminology needed to explain this properly - I just know what I can see, and how I solved it!
