Question Alesis HD24 dead

Hi,

I have an Alesis HD24 for that I've been using for some time. Last time I went to use it I tried powering it up and the fan came on but no lighting on the front or anything would happen. There was a loud signal that would come out of all of the analog outputs. I'm looking for a repair center or some advice on repairing it.

Thanks,

Kirk Thompson

There is an HD24 Yahoo group that can probably help you out. They have lots of very knowledgeable folks.

Google HD24 Yahoo group. I am not sure if you have to join up to ask your question. I am an HD24 owner and joined a few years ago. I get emails from the group every day. I bet someone there will help you out.

See my last post....
Note ...this repair requires whosoever attempts it to have knowledge of Testing and repairing SMPSU's,
And all rails should be tested disconnected from the unit first
Be warned !, or you will have a very expensive doorstop.

Sorry if offering a large group of world wide users is bad info. Maybe one of them can answer his question about where to get his HD24 serviced?? I guess that is not a good idea? I never suggested he repair the unit himself.
Why don't you point him to a repair center so he can get the unit fixed?

HD24

Thanks guys, I am a member of the Alesis HD24 group and I too get emails daily. I have asked and got hundreds of answers. The one I wish I could get would be.. (example) Yeah Jimmy Williams does all my repairs and he is reasonable.. his number is 123.456.7890.

I didn't mean to get an uproar started here..

Thanks,

Kirk

You might just want to call Alesis and ask whom they would recommend.

I wonder if there is really anyone at "Alesis" anymore, or if it is just the "high-end" label for Numark? Yes, I am bitter that they have abandoned the HD24 and not even produced an equivalent follow-on product.

I have a rebuilt HD24 power supply module which I bought to try to fix my HD24, but it turned out that there was nothing wrong with the power supply, so my "spare" is sitting here on the shelf gathering dust.

My HD24 (which I converted to XR with the EC2 upgrade) died in transit back from Europe as checked baggage. Apparently there is a hairline crack in the massive motherboard. Chances of fixing that are apparently zero. :-(

Those power supplies are pretty easy to fix, at least according to my tech, Jimmy Williams. Usually the switch transistor is out, put a new one in. The rest is diodes and caps. There are other parts that switch on the fan and stuff, that is probably ok. They used pretty small filter caps on those, like 330 uf for the negative rails. Use 1000 uf or more and that helps.
