jpgaribaldi, it is possible that it is the CCFL but there is also the possibility that it is your inverter circuit that has failed. There are a few transformers on your power board that drive the CCFL, one of them may have failed. I suggest you disassemble your monitor and take a good luck at the power board. For the 191T the inverter board is Samsung BN44-00041A Backlight Inverter. CCFL's are also available and are not that expensive, but we would need to know your exact panel. Again, for that you would have to disassemble your monitor.
