    Video issues present. Pulled logic board and seems there is a possible burn but I'm not sure. Can someone post a pic or direct me somewhere that shows what this looks like? I have made this into a tinkering project.

    Capacitors look good
    Powers on so I assume power supply is good

    Guessing logic board bad or video card bad. Any suggestions would be appreciated. Thanks

    The attached picture shows the area of concern... I think its alright but am not 100% sure. If someone can tell me what they think that would be great. The are of concern is the discolored dots right below the U3 chip pictured. Thanks

    If all is ok I plan to ty my hand at reflowing or reballing the video chip.

    Thanks

    iMac G5's are terrible machines. Honestly --- I'd tell you to take the HDD out while you still can, and sell it on ebay. Add 50 bucks and you'll end up with an early intel iMac. Much better solution.
