Q: iMac G5 PPC white lines all over screen???

I really like my iMac G5 PowerPC G5 and just recently I noticed one blue vertical line on the left side of the screen. I turned on my iMac this morning, which was three days after noticing the blue vertical line, and there are now white lines that are about half an inch thick covering the entire screen! I can hardly read anything on the screen. Is this a hardware or software issue? How can I fix this problem???

 

If you can help me it would be greatly appreciated,

 

Thank you

iMac, Mac OS X (10.5.8)

    Perhaps the lcd is going bad.

     

    G5 has these hardware issues:

    -- bad capacitors on logic board

    -- bad capacitors in power supply

    -- badly soldered video chip

    -- Allan Jones 

        There were several Mac models with flat panel displays that had bad displays. Most had serial numbers beginning

        with "W8"---the code for one specific factory. This affected PowerBooks as well. If that's the case, the rest of the  computer is probably fine.

    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.

    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.

    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.
