Hi all,
I've recently dismantled a friends old Apple iMac A1311 which would no longer turn on. I've removed the hard drive and got the data off.
It's an old machine now, not worth much and she's replaced it, but I wanted to try and fix it anyway. A quick removal of the power supply board showed some scorch marks underneath and black smoke stains in one corner of the device. It's not clear to me even from looking up close as to exactly which component has failed: I don't have the experience yet of knowing the failure characteristics of the various power supply components.
We're in rural New Zealand and the 230V mains power fluctuates wildly. Since moving here I've had a number of electronic items (eg: laptop chargers and other transformers) fail on me after years of faithful service elsewhere.
For those of you more experienced than I, where do you suggest that I start? I'm quite keen to start attempting to test and replace components, with some guidance.
The AcBel model number is: OT8043
The Apple part number is: 614-0444
