Q: does apple replace capacitors on IMac G5's PowerPC

My iMac G5 PowerPC's screen pixelates and then freezes.  I read that it could be capacitors that need to be replaced.  Does Apple still work on the old G5's or should I take it someplace else?

iMac, Mac OS X (10.5.8)

    It's old enough that you'll need to find a third-party repair source. Even some early Intel iMAc are now classed as "vintage."

     

    If you post a rough idea of where you are located, perhaps someome will know of a trusted repair place near you,

    You may have a problem with the video chip.

     

    Here is how to tell...

       Shutdown your machine.  Hold down the shift key.  Poweron.  Bootup will be longer.

         Wait awhile while you harddrive is being checked.

       An article on how to boot into safe mode.

    Runs OK in safe mode...

    Running in Safe mode leaves out some video drivers.  Which results in your machine not using advanced video hardware. As luck would have it, you can run the safe mode video drivers in normal mode. 

     

    Here is how:

    Look through the above thread.  See the second page.  You don't have to read through the first page.  Just go to the part where I try a solution that works.

     

    Using the safe mode video driver results in these limitiations:

       -- OpenGL acceleration is not supported on this mac

       -- Your mac lacks quartz extreme acceleration
