How to replace an iBook G4 backlight

[wescoolya]

did you fix the distributator thing yet?

[scidsecret]

Oh... And you shouldnt place a drink near a computer that you are working on!

[scidsecret]

A better way to test if it's the backlight or inverter is to get a multimeter and test for current coming out of the inverter. From my experience, liquid damage usually causes the inverter to go (not the backlight).

[ilcongia]

ok thanks...but is the procedure to substiture it the same?

THANNNNNKKKSSS

[ilcongia]

Is it the same on powerbook 12"???i have the same problem i think!!!you are great!

[neotoy]

The bulb (CCFL) length is critical. Since the difference is only 0.1 inches I would assume that it will work. If not you can look around on lcdparts and find one that's the right size.

tu si que le echas cojones

[charlessmyth]

I wondered if it would not have been possible to measure the voltage of the inverter's output jack with a multimeter before buying a backlight, etc.

[neotoy]

Good point. That's what I get for assuming that it was just the backlight! It's also possible that both were blown, and I have no way of testing the CCFL so I'll never know. Luckily I am one of those crazy types who likes to take things apart just for fun.

[charlessmyth]

Sometimes the challenge is getting them reassembled. I recall taking a friend's hairdryer apart to mend the thermal cutout and spent over an hour clipping it back together. Made in Italy. No wonder their economy is in the toilet :-) A useful thing to have is a working secondary to swap parts, so long as you don't mind getting a reputation as a board-jockey.

Just admit, the display will be BRIGHT now. I need my back light changed too, the display is starting to get darker. Nice video!

@neotoy

It's not. The voltage and frequency are too high for a regular multimeter. You might try it but u risk damaging the Multimeter & inverter if u just connect it across the terminal.
