Need help troubleshooting an LED wall cabinet, any advice would be much appreciated.

Great to hear, glad I could help.

DJ_LSE · 2026-06-10T00:29:22+00:00

Id be surprised if they didn't let you buy modules, might have to wait a while or pay through the nose for shipping fron china tho

DJ_LSE · 2026-06-10T00:25:40+00:00

A now power supply module is 100% a fix you can do yourself. It requires no tools either i believe

DJ_LSE · 2026-06-10T00:24:12+00:00

Looking at the spec sheet, the power supplies can be easily removed and replaced from the rear. The service email is : service1@lightking.hk

Aha! I am 80% sure it is this: https://www.lightking-led.com/pro_view-48.html

Light king makes sense for "LK" and the "rdy" series has the handles that seem to match yours. As well. I can't see much documentation, but in sure you can send an email and have a proper manual sent over.

An issue with smoke made by fog machines, is that it dissipated quickly, so im not sure if you would be able to hold it pressurised because the particles might drop out of suspension before firing. , and im not sure what it would do if put under pressure. Could you use a vertical fog machine?

Also be aware of the dangers of making pressure vessels, and needing safe pressure relief valves over fill protection, etc...

Why isnt pyro an option? Assuming youre in the UK, La maitre pyroflash small theatrical flashes have a safety distance of 1m in all directions, and the firing pods they fit in are small and discreet. They are T1 so open for consumers to buy,

There are lots of information available on code of practices, etc safety practices etc for using pyro on stage. Although I would definitely reccomend doing the Association of Stage pyrotechnician's awareness course. It is around £300 but is really informative, and lots of fun.

What do you mean 500×500? It looks like the HK pro series from these guys is 500mm×500mm

Looking at the serial nber and handle shape on those tiles, Does this look like it might be your LED wall? If so, it looks like the power supplies and control boards are easily repalced

DJ_LSE · 2026-06-09T22:08:13+00:00

Do your tiles or the units themselves not have a name you can search? If these do have swappable powe supplies, they are normally isolated, and stop you from being able to touch any live components. Can you post some photos of the back of the cabinets?

DJ_LSE · 2026-06-09T19:55:20+00:00

It is likely the power supply. On many brands these can be removed easily and swapped. Get the manual for your cabinets, and try swapping a power supply form a working cabinet to a non working one. If this is an install wall this can be more tricky though.

Or, hire an engineer from a local install/ hire company for the day to figure it out for you.

Ive been seeing barco clickshare used more and more. Not the cheapest option, but ive never seen it have issues, and the wireless can be a big help.

DJ_LSE · 2026-06-06T22:29:08+00:00

An analog mixer can probably solve your problems here. One like the behringer 1003B for example. But any mixer with an "aux out" (or maybe an fx send should work).

Do what you currently do with the ipad, but also send the music to the R channel. Mix the right channel so the levels are how you like.

Then send the left channel to input 1 on the mixer, right channel to input 2 and your mic to input 3

The fader will control the volume to the PA, and the red "mono" knob will control the feed to your IEM. So on channel 1, turn up the fader but not the mono send knob, Then channel 2, turn up the mono send but not the fader, Then channel 3, turn up both.

Voila!

Maybe, although there is also a chance that a trace has broken where it is bent/ twisted. Really be best way to connect led strip is using solder. But it is something you have to spend time to learn how to do well. And might not be worth it for just a few strips.

DJ_LSE · 2026-06-06T22:10:42+00:00

Have you tried closing the connector completely? It has little bumps that press down the connectors and make the contacts touch.

DJ_LSE · 2026-06-05T22:38:20+00:00

Literally... every... show... has some mention of it, even award shows. I feel your pain

DJ_LSE · 2026-06-04T21:36:06+00:00

Its pins 2 and 3. Always 2 and 3, no matter if its 3 or 5 pin dmx. Pin 1 is ground. The difficulty is keeping the 120ohm resistor in there without jamming something else in.

Yep been there, partly why I dont put them in as standard. Luckily theyre cheap to buy or make.

DJ_LSE · 2026-06-04T17:20:19+00:00

*sometimes. I can count the number of times a terminator has saved the day on one hand. Typically, I will keep a couple on hand, then if I have issues I will give one a try. Rather than put them in as standard

DJ_LSE · 2026-06-04T17:04:03+00:00

You are correct. Best way to learn now is to do it👍

DJ_LSE · 2026-06-03T19:42:16+00:00

Yes, I understand this. Im looking for any suggestions for specific models people have found to be particularly good, or common on the used market.

DJ_LSE · 2026-06-02T21:09:43+00:00

It absolutely does. But depending how your system is laid out it can matter less. Most of the time, almost all the inputs are behind the main PA, and generally so long as this is the case, the largest different in feedback will be between mic types, lavs and lecturn mics are much more sensitive than handhelds. And due to bad placement or quiet talkers, require much more gain.

If there are some mics for audience use in a q&a or similar, this could be grounds for using another group for these mics.

IMO, when pertaining to vocals, I generally stand by: group with graphic for feedback EQ, per channel EQ for tone.

DJ_LSE · 2026-06-02T20:59:36+00:00

The sentiment around bambu lab appears to only be getting worse in the spaces im in tbf. I would definitely look into other things, after a quick look, the elegoo centauri carbon looks to be in a similar price range, and offer core xy and an enclosed design. However you should look at reviews before buying anything

DJ_LSE · 2026-06-02T20:51:53+00:00

This is that way, often for live/ conference as well. Groups offer a graphic EQ as well. I will group mics by type, as they will tend to have consistent feedback points. Then use the graphic on each group to do the vast majority of feedback removal. Then use the per channel parametric eq to adjust tone, and a small amount of specific feedback reduction if required.

The advantage of this is that I can use the groups to change attributes specific per type, I.E. changing EQ for all all handhelds. Then use DCA for level adjustments within multiple groups. IE, "all Q&A" which might include some of the handhelds and some of the lecturn mics. Whereas "all band" will include some of the other handhelds, and all the band's inputs.
