A600 faulty power supply ?

[Giana]

Dear all,

One of my A600 stopped working.
It does not boot anymore and only the caps led remains green.

I decided, first to check the PSU voltages.
Here are the figures :
-10,2v instead of -12v
5,1v instead of 5v
11,3v instead of 12v

Do you think the PSU could be faulty or the figures above are within the normal variation ?
When switching off, the PSU does a little air sound : "pfffffiiiiit".

Now about the A600. I think about a recap. Do you think, according the caps led, capacitors could be the faulty items ?
Can't do the recap myself since I do not have enough experience with soldering tiny components on pcb, I'll have to find an Amiga repairman : someone to recommend ?

Many thanks for your advices.

When you say "one of your A600 stopped working".  This implies that you have multiple A600's.  The obvious question here would be, have you tested it with a different power supply?  If you suspect the problem is caused by a faulty power supply I would swap with a different one as a test before thinking about recapping.  Good luck!

Or, test the suspected faulty power supply with one of your other A600's! :p

Giana, Where are you located?

His avatar info states he's in Switzerland.

@Giana

Some suggestions for repair near Switzerland...

Hey,
I just have one PSU since I use one A600 at a time.
I know, it's stupid, I should source at least another A600 PSU ....

Here are the figures :
-10,2v instead of -12v
5,1v instead of 5v
11,3v instead of 12v

5v is the important one, the others being mostly optional

Do you get any video output?  Black screen?

I suspect it may be capacitor issue which is holding reset low (high?).   If it's not already been re-capped then it's long overdue (same for your other A600s).

Three goes the charm !!  Each morning.. switch on A600 and nothing. So I do the old Ctrl-Left Amiga-Right Amiga and ... nothing... Third time is the charm and always works so a  Ctrl-Left Amiga and Right Amiga and like magic she always works. Or you could try talking to her nicely. That has worked also for me.

I have like 100 Amigas and not one is capped. They just work.

Like this one today.....

If I were you I would get another power supply.

Until they don't.

And you open them up and find the caps have eaten through your motherboard.

Oh well, I guess if one goes, you still have 99 others to play around with. :lol:
