I just did the test you said, and my one good CCFL rack lights up good on both bulbs on both ccfl connections, and the other rack has the bulb out on both ccfl connections.

Re: Hannspree hf237 problems
UPDATE:
with screen fully disassembled we tested both pairs of CCFL's. the one pair lights up fine for 2 seconds, then out.
the other pair, one light, lights up, and the other light is dead. and it makes buzzing noise.
i will be adding pics of the boards and CCFL's
