I know there are other similar threads but I need answers tailored to me and how far along I am in repairs already.
I have so far replaced the LCD screen, inverter board, and inverter cable (individually) on my Early 2008 Penryn macbook 2.4ghz because my backlight keeps failing. I can still see the image dimly and external monitor display is fine.
The backlight will come on upon power up for a short time then go off, and for a short time doing the "brightness down then back up again" thing will work, and after that there's nothing I can do to get the light back on, not even restart.
After I replaced the LCD last night I used to computer solidly for around 3 hours but 4 or 5 times if I touched the screen or moved the laptop even the tiniest amount the backlight went off again. I closed it to go to sleep last night (not shut down) and this morning it is back to not coming on whatsoever.
So:
- clean the fan, logic board and apply thermal paste?
- Try ANOTHER inverter cable?
- Try to diagnose some transistor cold solder joints on the logic board?! (I'm not actually very computer savvy but have read this possibility elsewhere)
Please help and thanks, it's sooooo annoying!
