    MYRRA 44969 (conforms to 61558-2-6)

    Yup. That's the little devil right there. I suppose you gurus are much more adept at finding parts than I am. Myrra doesn't carry the exact model any more and I was considering going with the 12VAC unit from them as well, once the footprint is identical. It feeds an LM7905 so I suppose whatever...

    MYRRA 44969 (conforms to 61558-2-6)

    Yup. Searched the site, even eBay and Amazon. the closest I'm getting to the original voltage on their site is 9VAC and 12VAC. Nothing resembling the original. Checked DigiKey also. Nothing close.

    Dim output on one color on LED PAR

    Hi 73's de Edd, glad to hear from you and I recall you've helped me in the past so thanks in advance once again. I've learnt quite a bit since you last assisted me but I still have so much to learn. I have ascertained that it is not an LED problem as the plate works fine on another PCB so it's...

    Dim output on one color on LED PAR

    Cleaned up the solder points a bit. Which cap were you referring to?

    Dim output on one color on LED PAR

    Yellow circles denote parts that were swapped out.

    Dim output on one color on LED PAR

    Yes. The soldering is poor but I'm getting a little long in the tooth and the components are tiny soooo.......those poor solder points are the parts I swapped out from an old mainboard just messing around looking for the cause of the problem. When the problem is resolved, I'll neaten up...

    MYRRA 44969 (conforms to 61558-2-6)

    Hi guys, I'm checking a dead DMX output on a Martin RS-485 DMX splitter and I've got a dead 120VAC~10VAC Myrra 44969 isolation transformer. I've searched online at DigiKey, FuturLec and AllElectronics with no positive results. Any ideas where I can source this P/S? Thanks!!

    Dim output on one color on LED PAR

    Well, first let me say it's been quite a while since I posted and the change up of the website took me by surprise and it took me a while to find out how to add a new thread but here I am. I have some LED PAR's in my lighting rig and one of them recently developed a problem. The units are 18 x...

    Brother P-Touch Labeller not powering up

    Hi all, just did some testing and the voltage input into the main PCB terminal with the blue/orange wires is fine at 12VDC from the wall wart through the voltage PCB so I think that would rule out the voltage input PCB so it's looking like an issue with the main PCB so I'm going to tray a little...

    Brother P-Touch Labeller not powering up

    Hi Wizards! I have a Brother labeller that died on me and I would really like to get it functional again. I've opened up the unit but I am in no way knowledgeable about how these units work. The unit receives 12VDC power from a wall wart and I am receiving 12VDC coming into the main PCB from...

    RGB Laser Power Board Issue

    OK. I'll check tomorrow and post an update. Thanks!!

    RGB Laser Power Board Issue

    I will ask the supplier. I can't do any testing right away as the unit is packed away in pieces back into it's flight case so I'll try to make some time, reassemble it and take some voltage readings off of those terminals on the main PCB. That's the right track, correct?

    RGB Laser Power Board Issue

    Of course I'll use a large enough power supply. However.....each individual diode driver PCB is switched on and off via outputs on the main control PCB (Picture 1, three small terminals on the bottom in a row). These three terminals run to each driver PCB (Red, Green, Blue diode drivers) and...

    RGB Laser Power Board Issue

    Yup!! These diodes are dead. I am getting new diodes to replace these burnt out diodes but these new diodes come with a separate driver PCB and they operate on 12VDC so I just want to confirm one thing. The existing power feed to the original diodes is via one 5VDC P/S so all I will have to do...

    15R Lamp Ballast. Worth trying to repair?

    Hi wizards! I suffer from occasional lamp ballast failure in my moving heads carrying 189W Phillips Platinum 5R lamps and 330W 15R lamps. The normal problems are ballast failure and lamp failure (lamps are rated at 2000 Hrs for the 5R so this issue is rare). The ballasts are fed by a power...

    RGB Laser Power Board Issue

    OK. latest update. I tried one of the replacement rear panel PCB's with the voltage control PCB and the problem is still there. So I did some digging and found a similar relay in a parts bin and changed it out and re-tested the unit. It powered up with no voltage to the 5VDC power supply then...

    RGB Laser Power Board Issue

    OK, did some further testing. There's a definite drop across all the outputs once the power supply is connected, even after I resoldered all the traces and checked everything for continuity and everything's fine on that side. I have the original PCB's and two replacements that the supplier sent...

    RGB Laser Power Board Issue

    Hi kellys_eye, all the outputs are paralleled so I didn't check the other outputs because, although there are three outputs, only one is used so I will test that later but logic dictates that I should get 1.5V on all. I'll resolder all the traces before I test also. I checked all the harnesses...

    RGB Laser Power Board Issue

    Hi all, I have a 1/2 watt RGB laser that was purchased quite a few years ago and it was DOA. Because of this, and a lack of spare time to fiddle, it's been packed up in it's flight case all this time and I basically was using the flight case as a trolley/workbench for other units being repaired...
