Thoughts on repair after lightning took out modem and iMac
My in-laws gave me their iMac that got taken out when lighting hit the cable TV lines in their yard. Two cable boxes and the connected TVs are dead. The cable modem was dead. And the iMac that was connected directly to the cable modem doesn't work. I don't think any lighting energy traveled through the AC power lines into the house, just through the cable lines.
So I'm working on the theory that the logic board absorbed a lot of energy from the modem. Interestingly, this computer was repaired under AppleCare a couple of years ago - the logic board was replaced because the Ethernet port was not working.
The computer won't start up. Nothing appears on the screen. The power button will start the fans and I can feel air coming from the top vent. I can power off the computer by holding the power button in.
The computer is mine to keep. They've already replaced it with a new one. I've got plenty of computers and I'm not going to run a life-supporting medical device on this thing. But I feel the call, the challenge, to bring this thing back to life.
A logic board is a given. Other parts and components that may need repair or replacement:
- Power supply
- Display components, inverter, etc.
- LCD display
- Hard drive
- Bluetooth adapter
- WiFi adapter
- Optical drive
So, what do you all think about how deep I may get into this before it works again?
