Hi,
One of our Powered PA speaker starts to drop out every 30 seconds after it has been on for about 30 minutes. It actually switches off completely and then comes back on in 5 seconds like clockwork. It stays off the exact same amount of time every time.
1. Tried another XLR Cable - No Change
2. Tried running from another Mixer - No Change
3. Tried another IEC Power cord - No Change
4. Tried in another power outlet in another location - No Change
5. Removed and re-inserted the Fuse - No Change
6. Ran it at a very low level with a full line level signal - No Change
7. Ran it on Volume level 3 with a weaker signal off the mixer - No Change
8. This speaker has a massive Heatsink and it was not even warm but we put a cooling fan there anyway to see if it made a difference - No Change
9. The input on this a combined XLR/JACK . We tried JACK from the mixer and JACK to the speaker - No Change
10. We use this for a Band. We even tried a Music player - No Change
We have used these speakers extensively gigging with no issues until now. The other speaker is fine.
I think we have tried just about everything we can without taking it somewhere else.
I anyone can suggest any other things to try it would be much appreciated.
Thank You

What make and model is it?
It sounds like a problem with a switch mode power supply, but guessing without more information

Have you called the manufacturer about a warranty or repair? If they'll replace the plate amp (or parts) for free, that's infinitely better than breaking it open.

No warranty (got a few years out of them. Expired) or service centre in Australia unfortunately
Thanks

Yeah that is an internal issue, an audio equipment experienced electronics repair shop or technician might be able to find the problem.
Probably blown power amp , so power supply starts feeding it, and detecting a short self turns off, very hard to impossible to solve without schematic or authorized service.
Write straight to Soundking for help/advice, at least get the schematic or service manual, otherwise get tready to junk the plate amp and install a generic one there.
Not the same thing but the alternative is junking the whole speaker.
I usually treat orphan mystery brand stuff as disposable, sorry.
Here in Argentinab lately it´s very common to find *small* PA companies or Clubs using mixed brands of powered speakers; looking behind you either find a large piece of plywood covering the original amp hole with a couple speakon connectors mounted on it (and certainly an internally mounted passive crossover) , or maybe an adapted generic plate amp, same thing.
*Speakers* in general are good and worst case easier to replace, but complex DSP processed power amps, not so much.
