Is there a standard pinout for the 6 pin connector for these boards?
If I was sure that the inverter was getting the correct input, I would
be more comfortable blaming the CCFL. I will start looking for a
replacement though.

Is it common for a ccfl to blow after replacing the inverter?

Thanks for your help.

More to the point, it's likely a weak CCFL was the issue from the start, and
the inverter was shutting down- they do that by design. It's possible the
new inverter's shutdown detection threshhold was slightly different, giving
the illusion that all was well for a while. You may find the old inverter
works fine with a new CCFL, it's impossible to say for sure.

I can fix these things quite easily when they're in front of me, but it's
very hard to make accurate internet guesses.

Some inverters burn up if they are powered without a load as well

Ok. I took the CCFL out this weekend. What a pain. It does look like
it may have burned out. It looks like the connection on one side may
be burnt. I need to get some calipers and measure it and I will order
a replacement.

Thanks,

Andrew

Yes, often they can be a real swine to get out. Good luck with the repair.
