So I picked up an LC580 and everything seemed fine. Caps weren’t leaking. It powered on and ran good.  I decided to wipe the drive and reinstall. During install all the sudden it went dead. Just powered off. No smoke, no smells.  If if I hit the power button it makes a series of high pitched...

Ok. Update. I found that pin 11 of UC8 had no continuity. So I resoldered the joint and it is not working 100%. Apart from the fact I still need to address the logic board. 

Ok this is on an SE/30 that I’ve been trying to get working for a while. I took it to JJ Dasher and he was able to get it to this point.  It does boot to the finder. But at every stage it has this weird double image thing going on.  Has anyone encountered this before.  Before anyone asks, yes...

For me this was an interesting project. I had a IIcx growing up. So I bought a IIci. It wouldn’t start. So I recapped it, still didn’t start. Replaced both HC132 chips, still nothing. It had what I would call, serious damage from multiple cap leaks. I then found some of the vias that tie to the...

As an added note, the clock wasn’t working. As in settings were being retained, but time wasn’t passing. So I desoldered the RTC chip and put in another from another board I have. That fixed that issue. Guess the battery that blew up and leaked ruined the RTC chip. The unit seems to be 100%...

Ok. I fixed that issue. The 132 did have a pin that was not making contact with the board. Rather than mess with it I just desoldered and replaced it.

Ok. I didn’t have a chance to delve into it too deeply last night. But it’s good to know about other suspect areas. The PS is not the issue, I have three good power supplies, it always does the same thing. I’m hoping to have time tonight.

Already mentioned in my original post.

Oh. Thank you. I'll change out those chips tonight. The schematic is perfect for checking continuity. I'll see if the traces are good.

Ok. I'll go ahead and replace them. I'll let you know how it goes.

Nope not keyboard. I do have two keyboards. It does this whether or not the keyboard is even plugged in and it makes no difference which keyboard is used.

So I'm far from an expert and new here on the forums. I just successfully recapped and repaired a IIci. However when it's plugged in it powers on by itself and when you shut it down it powers back on. Not the worst problem, but I would like to fix it but I don't know what the cause is and I...

I had three IIci boards, one of which had a battery that exploded. The one with the grenade in there was the only one that was fixable so far. All three boards were recapped, but only the one with the battery issue responded to the treatment. So while that may look bad, it might work out ok. On...
