Shine a flashlight at a low angle across the screen while it's running. If the picture is there, you can see it.

I've replaced CCFL on about 8 sets, and had only one go easy from start to finish. eBay is full of the CCFL lamps - search "backlight lcd tv" for replacements. They are measured in mm length.
Also, if you are going to troubleshoot LCD sets, this tester comes in handy:

I have the HR Diemen TL1040 (mine was 90 bucks, but was the original back in 2004, before the Chinese made them), and it is a great go-no go tester for CCFL backlights for LCD TVs, monitors, and laptop screens.

I'm pretty sure that what you just described is what happened to my TV as the splash screen shows up fine but then it craps out once it goes to the source screen (e.g. tuner, HDMI, A/V etc.), I did shine a flashlight into the screen while it was powered up and I saw the screen but there was clearly no light source (like you said bad CCFLs) although what was weird is that I had a 12v power supply that was at 1 amp and when I hooked it into the TV and powered on the TV, the TV worked fine albeit with a high pitched whistling noise but it had a backlit screen and everything which when that happened I initially thought maybe a bad power supply so then I bought it a new power supply and plugged it in thinking that would fix the problem and no dice, for some reason when I hooked up the new power supply it went back to just showing the splash screen properly but then after that nothing even with the new power supply so its got to be something else causing the issue.
