I got a monitor here i wonder if anybody has worked with. Its a very high resolution 22.5
inch. I need another power supply I think. Can't find any documentation, Sony bought the
company out and closed it down, cause the technology was too advanced. So I
have a 200 dpi $10,000 monitor I need documentation for, namely the power pins.
Model MD22292-B2 or IBM 9503-DG1/DG3. I don't know if Sony ever sold this model
and used another #. Its a 6 pin connector.

I had IBM looking up #s but the docs listed on the website are not available.

Luck, I found the old broken supply. Things listed at 16 volts 10 amps.
Probably uses all 6 pins.

You probably won't find documentation. Just fix the original power supply,
any competent tech should be able to.

Maybe I will try to fix it. Such a hard deal trying to find another 16 volt supply. I
found one for $300. The IBM is on back order @$150.

Delta supply used in IDtech IBM model, now Lenovo, but monitor not
available due to Sony.

If you want to make something really cheap here you go..
http://www.lowes.com/lowes/lkn?actio...=cr&lpage=none

Just have to recitfy it and build some regulation..

That looks way too small and cheap to be 10A, I think 1.0A is a lot more
likely, looks like a doorbell transformer.

You don't want a linear power supply for that kinda power, it'll be a boat
anchor.

Hmm.. Now I go back and look at what it is you're probably right.. I thought
that was really cheap for a 10A transformer.

Well here's another thought. Couldn't you just get two 16v 5 amp SMPS for a
laptop and wire them in parallel? I've never seen it done, but I can't see
why it shouldn't work any different than wiring 2 batteries in parallel.

16 volt supplies are hard to find. I did find one by Acopian for $270.
I can get the orginal with some wait for $150. I looked at the supply
and its varying voltage constantly resetting. Nothing obvious I
can find.

Did you check the ESR of all the electrolytic capacitors? That's where I
start when diagnosing switchmode power supplies.

Probably doesn't have to be 16V exactly, 14-20V or so would probably be just
fine, but I don't think the original supply should be hard to fix. If you
don't know how, take it to a tech who does.

A lot of IBM laptops use 16V power supplies.

I didn't check the caps. I'll give it a shot. The supply is on order, but
that might be a problem since its not in stock. The logic seems a bit too complex
to troubleshoot without a diagram. You would think that the problem is likely a heat
overload problem.

I wouldn't. I would think the problem is likely bad capacitors, I see it all
the time, probably 80% of SMPS problems.

Yes, bad capacitors are the major cause of capacitor failure.

They fail for a variety of reasons, age, heat, electrical conditions, there
was a large batch with defective electrolyte.

Usually when they start to go, they work better as they warm up.

There are 15 V power supplies on eBay. Some may have enough adjustment
range to give you 16 V if that is absolutely needed.

I got my ESR meter and will check today.
The OEM supply has a coaxial looking supply cord. It has a little red
wire running through the center bundle for a sense line. I don't see
anything like that often.
