FLUORO CCT. HELP PLS

[tense]

Hi
Can someone help me with a circuit to drive a low voltage (6 volt)
fluoro tube from 6 volt input, I have one but is not working, it has 6v at
the tube but it won't light (the tube is ok). The circuit consists of a 3
leg IC, 3 capacitors, 1 resistor, a transformer and a trim pot, but I don't
know which component would be faulty. The IC has 411 and D882-Y written on
it and is mounted in a heat sink.

NOTE- remove 'e' from my email address to respond.

Thanks Barry

I'm guessing your "IC" is a 2SD882-Y transistor, where Y indicates the
hfe range.

I think Franc is right with the part number however I've found the
transformers go faulty quite regularly IME.
