Mac Mini G4 Flickering Screen at Start Up

Hi,
I have a mac mini G4 1.5 Ghz running 10.4.X. Last week the lcd screen started flickering.

The screen starts off fine when we restart. But as soon as it displays the apple logo, the flickering starts. It flickers (vertically) so bad (& wierd colors) that we can't even see well.

We tried to zap the PRAM but didn't work. Neither did restarting from Apple installer disc worked.

Then we changed the DVI connector, didn't work.

Changed to a different lcd monitor, didn't work.

Opened the computer and dust-sprayed, didn't work.

Does anybody have any idea? This mac is only 1.5 years old and is the first lemon we got from Apple. Unfortunately we didn't purchase extended warranty because I have used at least 20 different mac models (including refurbished ones) since early 90's and never had this type of problem.

Thanks for any input.

Did you check the wires?  Sometimes if you pull one loose it flickers.

Does this have a graphics card or is it on board graphics? The problem could be there. Also might test with a CRT monitor.

Hi, has this mini been opened up to add more memory?
I would suggest that before you conclude that the ATA bus is damaged, open the mini up and see if the ATA connector is still connected to the motherboard. (It's the same connector for both drives).

Mac mini display problem


Sounds like your monitor is not set right. Is the monitor LCD or CRT type? You can open system preferences from the top of the screen under the apple icon. Try and see if you can adjust the resolution settings. Also if you have an LCD screen set to "auto" adjust to reset the screen. Good Luck.

Help to change new HD in Mac Mini PPC G4


If you are unable to boot from the CD's, and you are sure they are the CD's that are supposed to come with that model (the bundled CD's/DVD's are model specific), you may either have bad RAM or other damage to the logic board.
Try holding "D" when you try to start up from the discs instead of C, this should launch a hardware diagnostic utility. Run that, and see if it finds any other damage to the machine.

Mac mini does not recognize web cam.


Mac's have a set of built in drivers that list a group of brands they support with out additional drivers. I can't remember which ones but they tend to like logitech cameras a lot better. They like iSight camera's the best.
