G5 randomly shuts off. What is problem, how do I fix it? Is it software?

Question

My G5 Isight randomly turns off. I ran diagnostics on hardware, but it didn't help. Is it software related, and do I have to re-load the original software? If I need to get it fixed, best way to get that done? Tips appreciated.

Answer 1

I am trying to figure out how to say this in a way that makes sense…
There were actually two REA programs, one of which applied to certain first generation 17 inch and 20 models of the iMac G5 family where specific symptomatic behavior was present, the other only for the second generation 20 inch model. The first REA covered both a power supply and the logic board, the second covered the power supply only.
In the first case, though both components were changed by service providers, seldom were both components actually bad. The primary issue involved defective electrolytic capacitors on the logic board.
The serial number ranges are of no consequence, because both programs ended almost a year ago, and neither covered machines which were otherwise eligible if more than three years had passed from the date of first sale.
It's relatively easy to determine if you are affected by bad capacitors, and if you write to the electronic mail address in my Public Profile I will reply with a short guide as to how to make this determination. It's not likely both a power supply and a logic board, although both conditions are sometimes present. If you are affected by a bad logic board, only refurbishing or replacing your board will correct the issue. If you write, include the serial number of your machine so that we can narrow the range of issues, and determine it's service history.
The refurbishment process costs $ 189.00 and the power supply is typically $ 139.00 to replace. As I indicated early, it is seldom the case that both parts are at fault.
