Well, as someone said earlier, a fellow (in the UK, I think) retrofitted a Sony (Sharp) single-CCFL panel into his 9300 (I think it was a 9300).
Then, Waynet tried with a nice high-end 2-CCFL WUXGA (Sony--Sharp mfg?) panel, and had real problems.
As far as I know, the differences between the two panels were:
1) failing panel was 1440 x 900
okay panel was 1920x1200
2) failing panel was two-bulb
passing panel was single-bulb
Try it, see if it works! You really have nothing to lose, and maybe much to gain.
EDIT: Dammit I gotta watch my editing...
What I meant was:

okay panel was 1440x900
