I have a followup question. I spent most of the day today replacing the 25 1800 uF and 1000 uF capacitors on my mother's old A1058 iMac G5, trying to resurrect it. 6 of the capacitors had obviously bulging capacitors.
Before the replacement, LED 1 would light up, then LED 2 would briefly light and go out. Now LED 2 lights up solid, but LED 3 doesn't light up. I reset the SMU, still can't get LED 3 to light up. Furthermore, the screen is most certainly not getting a signal.
I am fairly confident I reconnected the inverter properly (checked it twice), so I am curious what people would suggest I try next. Do the LCD displays actually fail (maybe due to the blown capacitors) often, or is this more likely still a motherboard issue? Any suggestions for what to try next would be appreciated.
P.S. - I do not have an external display adapter to test with at the moment (I am trying to see if I can borrow one).
