Hi pals,
I just got a - externally looking - fine 6100.
I tested the power supply: OK.
I replaced the 3.3v battery: OK
I looked for macroscopic leaking from the capacitors: OK
the HD works fine, I connected it to another Mac: OK
I turned it on: black screen, no BEEP
5V, 12V stable: OK
reset PRAM
quick on-off-on
It turned it on: black screen, no BEEP, no HD activities
I did then a closed inspection at the mother board, and I saw some sign of corrosion (see attached photos) close to some SM capacitors.
It did not look so bad to me but I decided to do some cleaning with isopropyl alcool and a cotton swab.
WTF!! A small capacitor went off a very very tiny one, I believe it is a capacitor (it is visibile in a one of the pics). The fact that it went off some easily it means to me that the capacitors have leaked significantly.
I'll recap the mother board, but the tiny capacitor is very small, probably beyond my skills and tools.
Can anyone please provide some comments?
Enjoy the photos
Please be kind to me
thanks
