Flickering Backlight after replacing inverter and inverter cable.

I have a black Macbook Core 2 Duo A1181 (last 4 # of serial are: F0P2) running Mac OS X 10.6.8
I started having trouble with the backlight on my screen a few weeks ago. The screen would go black after opening it up occasionally. (Note I could see my desktop and icons, it was just as though the brightness has been turned all the way down.) This problem became more frequent as time went on. I could usually fix it by closing it and opening it a few times. Then it would for for a variable amount time before going dark again.
I started with the two cheapest parts I thought it could be based on my research on this site. I replaced the inverter cable first, which seemed to make things better (darkness came less frequently), but did not fix the problem. Next I replaced the inverter board, also which did not entirely fix the problem. Now when the backlight goes out, I can usually make it come back on by turning the brightness all the way down and then back up again. Sometimes I have to do this 2 or 3 times before the back light stays on. Just reset my SMC again (which I had done before I replaced any parts). Haven't had it go out again, but I only reset my SMC 10 minutes ago.
I am wondering what I should try next to fix this problem? Could this be the CCFL backlight lamp? If so any guides for replacing that? (I understand there may be some soldering involved, but I'm pretty handy. I hope its this, as its a relatively cheap part). Or is it the whole LCD screen going bad? Lastly could this be the logic board (even though I can always see the icons on the screen even when its completely dark? I'd hate to spend another $150 replacing the screen (when I'm already in it $75 and haven't fixed anything yet) only to find out its the logic board (which I am not willing to pay >$500 for on a laptop of this age).
Oh, by the way, sometimes the screen will flicker as it goes dark or as I am turning the brightness down and up.
Thanks.
