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

Are you trying both machines on the same monitor? 

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...

Did you try a different cable?

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...

Forgot to add, but the IIe and PC card may have some to do as well...

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. .

Hi Uniserver,

Is this what you're talking about:

http://addison-electronique.com/catalog/category/view/s/station-a-souder-et-accessoires/id/146/?p=2

It is called XYTRONIC, maybe just a typo on your side.

If so, which model do you recommend?

That company will also probably have the capacitors in stock, they sells a lot of them.

something like this...   ebay.ca

man that looks nice... it comes with hot tweezers and everything else...  and it also looks like a hakko clone.

they have sold a whole mess of them!

Hi Uniserver,

Thanks, but no thanks! You really helped me choose something that look very cool, but you also relaxed my pockets by $150 U plan expenses! I think it is for the best, I hope. I'll just need to be patient, but with a kit like this things look easier than with a standard soldering iron. Should arrive in 2-3 days from the other side of the country? I'll see if that is true!

I just took a quick look at your website too. You already have a list of requirements for many models, that is great...

But on your main page you show:

Do you want stock capacitors? I can do that!

Do you want Tantalum capacitors?, I can do that!

Do you want Radials? Ceramics? Organic polymers? I can do that!

I'm no expert, and I'm not sure what does it means/changes for any of the variant shown here. I will need to order a bunch of them, as I guess most of my machines will start showing signs of age sooner than later.

I will test them all before going on.

I'm more of a Fan of MLCC Ceramics my self... I just love those little guys... but the only way i can get a good price on them is to order a reel of 2500 straight from japan.

Humm, I guess I do not need 2500 of them, especially that I will requires many different ones, which makes probably over 10000+ total. Wow...

Are you reselling them to us if asked (and have them available too)?

if you have specific questions you can just email or PM me.

and don't forget about Trag, he sells cap kits.

Thanks Uniserver.

I will contact Trag.

You've been of great help so far. That is, if I can make the recap myself, otherwise, I just burned $150 on an amazing soldering kit

It will look nice on your workbench at least! 

hahaha

<== I have to remember that I'm only a 6502, not an 68LC040 like you

Hi Uniserver and al,

I finally received my soldering station today. Amazing kit... There is many tools and tips included with it, just amazing!!!

I will need to try and test it a little before doing serious work on computer boards. I have, just as a coincidence, a Klipsch Promedia 2.1 sub on which I had to change the terminals on the back (a plastic terminal broke). I did the soldering with my old iron, but I thing there is some bad contacts in it as it does not sound right. So probably it will be a good starting test elements

I'll probably will need, especially for mother board caps'  soldering, to buy a slimmer solder roll, mine may be a bit too large to solder very small pieces. 

Lot of fun coming to my bench! I'll need also a good high chair, now I'm working on my feet which is not optimal...
