Alba LCD19advdw, LCD TV and DVD, 2009
So it is 2 wires per tube and 4 tubes, not 2 , it seems.
Tried 2 CFL tubes on the monitored side and both light for 1 second.
So I can leave one CFL in there and use the other supply to test each TV
tube plugged-in in turn, surely 4 could not have failed at once, for 1
second.
