(SOLVED)Samsung 32" LCD Backlight switches off after 2 seconds
downunder:
Yes, wise to replace it. Even one pinkisk CCFL can trip the backlight error.
Re PSU voltages, I simply don't know, but what's that cap sticking out sideways in the top of the picture, obscuring the board number?

I couldn't get a 1200 uf cap , so used 2 in parallel...
What do those tubes cost in Aus, I am trying to locate them here?
Turnip:
Tend to use tubes from screen smash sets, and 32 inch is pretty popular.
Most have wired ends so fitting isn't much of a problem although can vary a bit in length for any screen size.
Best of luck - Chris.

Expect 1200uF in not a preferred value. A 1000uF would have been adequate for the job, but no matter.
Not sure of price or availability (as they are often classed as part and parcel of the panel). I've never changed one in a Sammy. I know that Sharp ones have been available at considerable expense.
There are firms that deal in LCD parts including CCFLs. You could try fleabay or go with Chris's suggestion if you have a wrecked 32" lying about.

Found a good 2nd hand ccfl tube, popped it in and Bob's your Aunty!! So in conclusion, I changed all electrolytic capacitors on PSU/Inverter board and fitted 1 replacement ccfl tube. Thanks to all.
