 Post subject: Backlight not working
PostPosted: Mon Sep 01, 2003 3:56 am 
Hi,

about two months ago I accidentaly spilled small amount of water on my PB G4 (550 MHz, Gigabit Ethernet) in the upper right hand side area (near the power button and the right speaker).

Luckily everything appears to be working normally except for the screen backlight, ie. the screen is dark (although I can see the desktop, etc. if I point external light straight into the screen and look closely), the apple logo doesn't light nor does the power button and the little light right under the screen in the middle. The strange thing is that the latter glows (or "breaths") when I put the computer to sleep.

I can use the computer hooked to an external monitor and it works fine but, naturally, it would be nice if I could somehow fix the problem with the backlight. So, would replacing the inverter board solve my problem?

Your online store states that the inverter board that can be purchased from you works in 400/500/550/667 MHz model series. Is this correct? I'm asking because I've seen different replacement inverter boards for the 400/500 MHz series and the 550/667 MHz series on some of the other sites that sell powerbook replacement parts.

Thanks for your help,
Peter

You spilled water right over the inverter board, so that is the first thing I would replaced. Hopefully that is all you need to replace. From what you describe it should be. The inverter boards are the same except for the 667 DVI models and above.

It is on the left hand side (near the power in) It looks like a rectangle with a piece missing from it, and is where the inverter cable plugs into. Make sure the able is securely connected. If that doesn't fix it, then you'll need to replace your display.
