Hi Campbell,
Sounds like it could be  your starter unit is on its way out, or possibly
moisture is manging to get into  end caps  but could also be your tube
going,
A simple test is to switch your lights on  and observe  the starting unit if
it keeps flickering  then twist it as though you were going  to remove it ,
this sometimes allows the lights to stay on ,  if that doesnt work  then
would look at end caps to see if they are ok.
Hope this helps
Andy

I had an issue where one end of my Jewel lights fell into the water for a
while and had exactly the same symptoms you describe.

Basically I slightly opened one end of the "solid bar" containing the
electronics, propped open with a bit of wood and left in the airing cupboard
a day or two. Sealed using hot glue gun and black aquarium silicone and
lights have been fine for last two years. I always keep my old tubes after
changing every year (my algae starts up after a year indicating new tubes
needed) so they can be used to verify the unit is still working.
