LM14A problem

[nobody@xxxxxxxxxxxx (Dave Houston)]

I have an LM14A, reliable for several years, that has started acting up. I
wonder if anyone else has seen this behaviour. When it is turned off, it
slowly fades as it always did but now, just before turning off, it flashes
full on briefly before going off. Light bulbs normally last me for years but
I had to replace this one after only brief use shortly after this odd
problem appeared.
