Hi all
 
I have an Atomic 3k on a rig, doesn't repsond to dmx and flashes randomly no matter what i do with the dips,
 
guessing it is a dead dmx reciever board....is this a seperate part in the atomic or is there just one large insane board that does all the HT/LV and SELV?
 
Any info and suggested suplliers of parts would be most welcome,
 
cheers

Have you tried reversing the polarity of the DMX input?  If I remember correctly, Martin liked to phase invert all their gear from the regular convention

Hi
thanks, that went out several years ago,
all products since the mac 250 have been the right way round,
but good shout

It is all one PCB if I remember rightly. Have you checked the obvious i.e. is it getting good DMX?

I have the schematic somewhere if you need it.  It's all on one surface mount board but they're not too tricky to work on.

Illuminate,
I haven't scoped the line, bt its mid chain and everything after it is happy, channels above and below are all happy too
, i had a suspicion it might have been reflections in the unterminated line affecting just those channels. (obviously i tried it on different channels to dis-prove this.

I have not tried it connected directly to the desk to see if the same fault persists, this is the next obvious step, i'll take down 20m of dmx cable and patch it direct.

back in there on friday, so i'll have a proper play

thanks

Ceharden, that would be awesome!

I am fully experienced in hand building smt stuff, so i could potentially just replace the knackerd ICs if i can trace them well enough.

thanks

Best to try running the unit on it's own directly from the desk to see if you still get the fault. Is the DMX terminated?

If there is a fault on the main PCB board, i can repair it. Repaired a lot of the Martin Atomics, and have all the circuit diagrams & mods. PM if you need it looked at. Simon

Do you do other Martin boards?  I've got an Ego 03 board thats been dead ages - £185 for a new board simply isn't worth it!

I have repaired one or two, but the main problem with them is that the board is a four layered PCB board & the usual fault is around by the SMPS voltage adjuster circuit. When the board blows, it also blows a track between the layers of the PCB (which is near impossible to repair). So that is why i have choosen not to repair any more of the ego PCB's. Sorry. I think also this is why Martin has discontinued them as well.

had a similar problem with an atomic in a club i used to work at...
both atomics went down with the same fault... said it was receiving DMX wen nothing was plugged into it... and wouldnt respond to anything... and one would randomly go onto blinder mode and trip things out.... sent em both back to martin and got them back 2 weeks later after they replaced the main PCB

I know what the fault is, send it to me & i will repair it. PM me.

Hello Swenk,
I have exact the same issue with one of my atomics,
how did you manage to solve the problem? Did you replace any ic or component?
Many thanks,
Teccon

Do you have any spare 518 PCB's?

More faults... One of mine seems to trigger itsself but still responds to the desk. It's not an easily repeatable fault as it seems to happen rather randomly. All will be fine for a few hours then it'll trigger a few flashes every min or so, sometimes it'll go into blinder mode. I think its also chucking out some kind of signal as the sunstrips and led Pars next in line were triggering a little as well......

Any Ideas?

Sunstrips are bastards for chucking spurious data back down a dmx line, are you sure it was the strobe at fault? Did you try it on a clean line direct from your buffer?


Posted By: simonp1100

Check the strobe directly via your DMX desk first, i am assuming that you have terminated the last item in the DMX line with a terminator plug ??? & that the strobe is the only thing in the chain that is faulting ?????.
It sounds like one or more of your fixtures in the DMX line could be interfering with the strobe or it could be down to too much current draw on the rig & resetting the strobe (had this once & took me ages to trace it). Good luck & hope this helps Wink.

Hi all following the thread. I have a Martin Atomic 3000 unit I've picked up that's dead no sign of life.

Does anyone know where I can pick up the service manual/schematic ?

Thanks
Andrew

I can repair most atomic PCB's so if you get stuck and it's not the fuse get in touch!

Hey, I know this is from 2008. But I just had 1 of my atomics quit working. The "flash" light is just steady when ever it has power and martin says that means the pcb board is bad. But I dont have the funds to replace it. And nothing looks burnt. although r136 doesnt look great it looks like it could be fine. So I cant tell if its bad. Have you had experience with this before?

I could use that schematic if you still have it. I have an atomic that appears to stop functioning whenever it receives DMX, but still works on standalone mode.

Check you have no problems with connections on the XLR sockets as well as any problems with the pads of the these as well on the PCB board, then check for continuity on each pin of the XLR to R103 & R104 (R103 to pin 2 on XLR & R104 to pin 3 on XLR).

Check R103 & R104 they should be 2.2 Ohms & check D102 & D103 for shorts, if these components are all fine then it maybe IC102 (SN75176B) bus transceiver chip. Clap

An old thread but a useful one, I have a atomic 3k and the lamp seems to dim its output after a second when triggered, dims by around 70%

Any ideas guys ?

Have you done the usual checks of another unit with exact same settings next on same DMX line followed by swapping the lamp (after it's cooled and not touching with your fingers? Very poss a lamp issue, what colour are the ends of the tube? Also, The dips are often the first think to go so give them a wiggle and a spray clean, then..... 

There are many repair techs that just bin the boards and a few that like to work on them. If someone could cheaply create a replacement back panel and reliable electronics (push buttons not dips, LED display, separate LV and HV boards).... they could easily bring back to life hundreds of Atomics and make a few quid....

Just putting it out there..... Crowd funding....

Swapped the lamp out and same issue, the lamp had scorched ends but so does the other 5 I have lol.

I’ll give it a try with the dip switches etc, not looked at that, tried several DMX options and still have the issue 🤷‍♂️

they do dim when used as a blinder after a couple of seconds as they are sucking so much electrical current the greed things lol, never seen them do it when strobing though, maybe it's in low power mode, check the dip switches on the back
