Hi Everyone,
Attempting my first recap job.
After cleaning and recapping, I start up the computer (with the back access door removed). Loud chimes, happy mac, 7.5.5 begins to boot
HOWEVER around 30 seconds later one of the capacitors begins smoking and is glowing bright orange. I immediately pull the power cable out.
The capacitor had disintigrated. It was one of the two located near the PRAM battery, at spot C184. C13 was also pretty hot to touch, but may have been because of its proximity to C184.
Original capacitor: 47u 16v
Replacement capacitor: 47u 20L (so 20v?), Tantalum
I desoldered the severely burnt and damaged capacitor at C184 and tried another that was identical to the one that had just self-destructed.
However, now the computer no longer boots or responds to any key-press on the keyboard. That said, the capacitor was starting to heat up again, so I removed the power.
Any ideas on what would cause this behavior would be appreciated. Also, I'm wondering if when I was pulling out cables while the one capacitor was glowing hot and smoking I damaged the ADB controller and that is the reason it is no longer powering up?
Thanks
