Model M LED Panel help.
« on: Sun, 22 February 2015, 17:17:41 »
Does anyone have a spare Model M LED panel they don't need?  I could really use one.  It will connect to a 1993 1391401 controller.  I found a topic on it on here from March 2012, but didn't want to pull up that thread and necro everyone on it.

I don't know where to get them.
I believe I may need the ribbon too, but I suppose I could use cat5 wire if I need to.

Order one from Unicomp.  They aren't listed on the site, but you can open a support ticket with them to get one.

That's interesting.  I just don't want them to mess up and give me one of those 42H controllers or something.  I'd probably have to send them a picture of what I need, and hope they have it.  You may be right.  I just don't understand why they wouldn't have them to order directly on their site to begin with.

I think the part number for that LED PCB is 1393296.

Ha Ha Ha Ha

42H controllers are the only ones that I have ever experienced failing!

I guess I could just make one if I have to.  It doesn't look too hard to do.  I was hoping someone just had one lying around.

Yes I found it there.  If you read my first post, that's the thread I was referencing.

The Model M that I bought didn't have working LEDs either, and I fixed it jumping the ribbon connector with wires. It seems that the ribbon was somehow disolved or fried with overcurrent , maybe because of water ingress at some point in its lifetime.

The wires I used were telephone extension wires, which had the advantage of being single filament wires, easy to push through both connectors.

Luckily I kept the pictures:

91652-0

91654-1

91656-2

It would be very rare for the small LED pcb to be damaged, it has no logic in it, all it has are LEDs and a connector.
If the LED were damaged, you could solder new LEDs with your favorite color (blue, red, etc). There is a current limiting resistor in series with the LEDs on the main board, so you don't have to worry about the mainboard.

Cheers!

Also, in my case, I had tested conductivity between the ribbon cable extremes, and there was like 1Mohm there, so the ribbon was no good anymore, not even after careful cleaning.

I need a LED PCB.  Does anyone have one at all?

If I were you, I'd make my own out of a cut piece of solderable breadboard PCB, just a bit of soldering required:

       http://www.amazon.com/Solderable-BreadBoard-matches-tie-point-breadboards/dp/B0040Z3012/ref=sr_1_1?ie=UTF8&qid=1424660769&sr=8-1&keywords=bread+pcb

       http://www.amazon.com/Solderable-BreadBoard-matches-tie-point-breadboards/dp/B0040Z6OK6/ref=sr_1_10?ie=UTF8&qid=1424660769&sr=8-10&keywords=bread+pcb

but they should be available for cheaper at a local shop or elsewhere.

The model M LED pcb is extremely simple. A common wire and three individual wires to the LEDs. Mind the polarity, I think VCC was common and gnd was sinked individually for each LED.

Cheers!

Yeah thanks, I may just go to my local Radio Shack or something and find one.  Maybe get a few LED's while I am at it too.

I'd just like to say that this is the best way of handling very old threads.

Don't necro them - start a new thread and post a link to the original one :)
