I have searched on google and found ALOT of people who have experienced this same problem, but nobody has bothered to post the soloution?

 

For no reason, my iMac G5 17" has suddenly started to display, what appears to be in only Finder, small black vertical lines.

 

Now these small black vertical lines, appear in the icon areas.

 

For example, the "icon" area of the mouse, that whole box area that you get to draw your groovy new mouse pics is all vertical black lines.

 

Also any desktop icon is covered in vertical black lines.

 

The "window" around Safari, has a few black lines arouned it and it makes it generally hard to read anything that is displayed through or with the help of Finder.

 

Surly there is a fix for this and its not the iMac just suddenly for no reason dying..??

    First off, your machine is old enough any software updates that are available for it will only be on

    http://support.apple.com/downloads/

    Secondly, what is the icon between the Dashboard and the Mail icon?

    Third have you tried to run the hardware test that came with your Mac?

    Unless you installed anything else Apple did not ship with the machine, it is doubtful this is anything other than hardware problem, even if the test comes back negative

    TenFourFox is innocent, OK! (I use it myself).

     

    As only the Finder seems to be affected, I have a nagging feeling that this may be caused by a font conflict, i.e. a damaged system font.

     

    Have you checked that?

     

    Another thing. You wrote:

     

    For example I know on one bulletin board someone had fixed this same problem by deleting the com.apple.universalaccess.plist file (which at reboot will reset itself)- however that file already does not exist on my machiene so that must have been an intel based unit they were on.

     

    It should definitely be on your Mac in Home/Library/Preferences, but I doubt that is relevant.

    Atleast it seems like graphic card issue. I have the same machine and I am currently battling issues with it also. In my case there was artifacts like that and much more, I got them solved by changing couple capacitors... some other issues are however still present. If it is a real GPU problem, then there is basically choises for either reball or reflow the chip or get totally new chip and then solder it back or then get a new logic board. These models however are more prone to capacitor flaws on motherboard or power supply rather than GPU solder faults.

    I mostly agree with you. I bought my G5 iMac three months after they had been declared 'end of line' (and were thewrefore sold at a discount), when the first Intel iMacs came on sale. That was six years ago. I bought it to do certain specific tasks (converting 50 or so family videos to digital media including burning them to DVDs, scanning the family photo archive (goes back to 1855) of nearly 16,000 photos to create a digital archive, etc etc).

     

    It has continued to do all I ask, flawlessly. There are things I cannot do which I probably could do on an Intel Mac, but so what?

     

    But of course our G5s are 'old' in computer terms, but again, so what? My car is 9 years old and has no problems, I am 68 years old (wish I could say the same!). Reliability is what counts, not keeping up with the Jones's!

    I'm not bad mouthing TenFourFox, or the G5.  I just happen to know what a graphics chip issue typically looks like.  I had one with my iMac G4 which wasn't too different.  It appeared the same style only over my Realplayer window after it automatically changed resolutions on the display for me.   Apple ended up diagnosing it to be a graphics chip issue.  I got it with an older version of Google Earth on my iMac Intel Core2Duo but don't currently have the money to rule out anything else.     Thankfully I rarely use Google Earth, so I don't run into the issue that often.

    You can't use the installer disk from another vintage or model Mac on your Mac.  Call AppleCare for replacement installer discs if you lost them.

    Well it is either caps or bad solder joints. Cannot be fixed with any tests or software tricks. If it is caps, replace them, if it is solder joints, get them reflown or reballed.
