Powerbook G4 Backlight Not Working

kkkk let me be the boring generic forum lurker brb, Ok guys, I have been having some problems with my Apple Powerbook G4 1.67ghz 1gb ram 15 inch model it is I've tested the voltage at the logic board connection socket. I've already replaced the Inverter AND CCFL tube (very fiddly) and still have the same problem. However, the cable is more likely the culprit, so I'd say that's a better place to start than the inverter. navigate to this website 03/18/2010 by lemerise Show 9 more comments Add a comment 0/1024 Cancel Post comment Are you sure you want to delete this zzzzzz?

Then, I saw an article on the internet stating that I shouldn't put a meter across the outputs because it could blow up the inverter board.

Accidently burnt out the old inverter whilst probing - just after reading about NOT doing that... Oh yeah and, by the way, I know it's the backlight because I can see the faint images on the screen AND the laptop works fine when connected to an external Is there a way to test the inverter?

Here's the technique I used for testing an Inverter... If so, then something to try would be to max out the screen brightness (and leave it on max all the time) and short together pins 4 & 5. It's not a piece of cake to solder the two wires to the lamp. Man, this one is tough.
