How many CCFL tubes in 30" display

Wondering if somebody can tell me how many CCFL's there are in the Cinema 30 inch display.

Also, if you've have taken one apart, how long are the CCFL's and what diameter?

I'm trying to find some replacements.

Did you ever find a solution? Could you share if so?

I have two that I would like to fix.




many thanks for asking. well it was a other problem. the CCFL's are not damaged. the line driver are defective.


oh, thank you for letting me seems you had luck in fixing it, I hope I will be able to do the same.


I have two 30" displays and they are both showing dimming and yellowing with age but are otherwise perfect. Would replacing the CCFL's help? Does anyone know where I should look to find out?

Here's one of the last sources I know of for CCFL's: LCD Parts.Net.

I think there are totally 16 CCFLs distributed horizontally & evenly at the back of the LCD. I don't know exactly how long they are, but they are at least as long as the width of the screen, so the illumination could be even.

I've been wondering why there is so little information about the aluminum displays (A1081, A1082, A1083). I'm pretty sure there are still many being used, and some may need attendance. Maybe could show some instructions on this.
