    LED Driver unit with no output

    OK. I'll wait for some more feedback on both threads. I'd appreciate and views or workarounds on the other thread. It's a great piece of equipment and it's sitting down in pieces waiting on a solution.

    LED Driver unit with no output

    I'll probably order a couple of the SB3100's and SR160's in the interim from Digikey just in case and keep them on hand. I checked the NTE573-1 datasheet and I see that it handles a higher voltage so I'll keep that in mind when I'm ordering. I've started a new thread as I'm trying to modify a...

    Suitable substitute part

    Sorry about this late reply. The problem is, once I'm finished using these units for any jobs and they don't give me any problems, they're packed away in the warehouse until the next job. One of these did fail a couple years ago (not failed actually, it was broken off the pcb by the magnetic...

    TG3 Electronics Keyboard modification

    Hi all. I recently purchased one of these TG3 backlit heavy-duty keyboard/touchpad combos for use with a Leprecon LP-X24 lighting console but I've run into problems. The console functions perfectly with a regular keyboard and mouse but the when I connected the TG3, the touchpad section...

    LED Driver unit with no output

    Yes they do. http://www.steveselectronics.biz/ But I normally purchase hard to source parts from Digikey and have them shipped down to me but I normally have to let the order build up to a sizable amount then order. On to the good news. I installed the NTE578, powered up and everything appears...

    LED Driver unit with no output

    I'm in Trinidad in the West Indies. If the unit powers up, I'll still order spare SR160's and SB3100's just in case. I'll install the regulator, power up, and update you in a bit.

    LED Driver unit with no output

    I tested the NTE578 prior to installation and got 0.28VDC from one side and OL from the other and I think this is correct because the diode is supposed to allow current flow in one direction only according to the info I read. I then installed the NTE578 and checked readings at the LM2575 pin...

    LED Driver unit with no output

    Well, the SR160 is not available. Neither is the SB3100E. I got an NTE replacement, NTE578. It's the same type of Schotty Barrier Rectifier but the datasheet I got is very vague (and I don't really know what I'm looking for when I read it). It's rated at 1A 90V. Will this function properly?

    LED Driver unit with no output

    Thanks! I'll pick up whichever one's available, install it with the regulator, power up and update you accordingly.

    LED Driver unit with no output

    What value would a "meatier" diode be?

    LED Driver unit with no output

    I removed the diode and the number is SR160. I did a search on Google for information on diodes and these act as a one way switch for current flow, and I should get an OL reading when metered and low resistance when the leads are reversed. Did not know this so another day gone, another thing...

    LED Driver unit with no output

    OK. I lifted one end of the diode and took resistance readings as follows: Negative tester lead from Pin 3 to Pin 2 = 10.7kΩ. Pin 3 to Pin 4 = 14.5KΩ. Positive tester lead from Pin 3 to 2 and 4 = similar values as listed above. Does this signify that this diode is faulty?

    Great. I'll post my findings in a bit.

    LED Driver unit with no output

    Here are the closeups. Let me know if they're good enough. As far as connectors go, it's just the 120VAC/24VAC transformer going into the board then 8 LED outputs being fed out. The only thing connected is the transformer to supply power for testing.

    LED Driver unit with no output

    No signs of burnouts. The previous page has the pictures i originally posted. If you need closeups of specific areas, let me know because I don't have a clue where to start to look for faulty parts.
