Trying to revive some of my machines LC III and Performa 6115cd

6502
Hello,

After I moved 2 years ago, I am finally able to get my machines out and fire them.

I have two for which I want to make sure they work:

- a LC III in which I have a IIe card

- a Performa 6115CD with a 486 PC card

Both machines are chiming in when I power them up, but I can't get them do both or show anything on the screen.

I've tryed PRAM resets, replacing battery, and a few other things, but can't get them to pass the startup sound.

Anyone can help there?

Thanks

 
Tryed 2 different monitors. I also have a KVM, but I tried them both outside the KVM to make sure it was not the issue. Same results...

Caps, caps and more caps.

I was afraid that one would say that.

Since I pisted, I tried another LC I have and a spare MB for the 6115 with the same results.

Could the caps been wrong on all of them at once?

If so, I need instructions...

 
pull the cards out of both machines then try it… also the PM 6100,  make sure you have 3.6 volts on the battery, or you won't get any video.

The LCIII is known to not give you video if the caps are shot.

The PM6100 Should technically not need caps yet… but i mean they could! see if any of them are leaking… they could be starting to leak.

 
Yes, forgot to mention I removed the card too.

I will test the battery in the 6100.

As for the caps, I have not look at them very closely yet, but I did not saw an obvious leak either. I'll take a closer look...

 
Well all the LC's should all be do, all of mine were bad, just ask UNI he did them all for me last year it was I think, maybe the year before.  The 6100 is the same age pretty much, I just had to do my quadra 660 and my 6100 due to non boot.  So if they have been sitting even with non use they will age and leak, or dry up inside.  My 6100 didn't leak they were just all dried up, same with the quadra.  Might have been the fact there was more cooling, and more spread out, not sure of course.  

 
Well, that may be it then.

I am not a master of the soldering iron, nor that I'm probably not equipped with the state of the art soldering kit, but how difficult is it to do?

If they are dried out, can we just humidify them a bit? Ok, just kidding here... :)

 
Yes its pretty easy depending on how well you clean, and the quality of the soldering iron.

For almost 5 years I bought the cheap irons from radio shack and harbor freight.  One I got a soldering station with a real high wattage iron its like I was a sadist before.  It took so long to do anything before.  The iron would get hot, use it once, let it reheat and go again, rinse, repeat.  A real Iron gets hot and stays that way.

 
Can you point me at what you're talking about?

I' pretty sure I just have a pretty much standard iron tool. Bought it like 25 years ago for cheap...

 
Oh uniserver or anyone else probably know a better longer lasting model, I just went on amazon and bought a middle of the road 898D+ soldering station.  Then bought a separate flux pen, and a wire mesh cleaner rather than using a water sponge.  It has a hot air gun and a soldering iron so it does well for as little as I do now.

 
I googled it, what I have is not even remotely look alike of what I found! Just a plain iron stick. So I may have to invest in that before proceeding to anything to repair my Macs...

I'd like to have advice as to what's best for the price, what I should look for. I' min Canada, so I do not know if the same tools are available here...

 
Xtronic makes a good solid kit, It's a hakko clone. I'm a big fan of hakko! I believe it to be the best. If you get one of those 4 in one stations they'll can be quite handy. The hot air torch is great at removing old caps, just remember the more rotted and nasty the cap the more time you need with the hot air torch, if it takes 15 seconds per cap so be it, not worth getting frustrated, heat has to melt the solder, and the rot is like insulation. :( .
