Hi! bought the ta2020 MkIII kit from arjen a while ago.
I wired it up yesterday and im sure that i did the correct wiring. But there is a problem.
The powersupply that was supplied with the kit, when started the led is flashing on the power supply. and a clicking sound from both speakers and the relays is appearing. Its like a pulse. The same is for the Power LED on the arjen Board and the Over LED. I have video of it if requested.
Please help me, im just a beginner 🙂

something is shorting/drawing too much current - it's the protection kicking in. Mine did it when I was messing around with different LEDs. Double check your wiring.
Post a nice clear photo of your build and I can check for obvious errors. Also look for my post a few pages back - it has a good wiring diagram drawn by Arjen.
Next thing to do is take things out of the equation - try just the board and the psu (disconnect the speakers and inputs)
Then add things back one at a time till you get the problem again.
Edit:
Here you are - this is how the input side should be wired

Thanks! ill try it, im quite surtain that i did the input right, i have no channel selector so its simple.
Thanks for the advice! found the problem, Took out my potentiometer and the voltage from the powersupply was like 1,5 volts.. so i adjusted it and it works perfectly!
the short/problem will be on your 12v circuit somewhere.
does the PSU flash when it its plugged in on its own not connected to the amp?

Its fixed now! haha the voltage was turned down to 1,5 volts on the smps so, now i turned it up to max and the smps led is no longer flashing, the Power led for the amp board is fluid and the OVER just flashes for a milisecond when starting (i hope that means ok) So no problems! thanks for the advice tho
check the dc output with a multimeter if you know how just to make sure it's sitting nicely at 12v. The ta2020 can take a bit more voltage and I doubt that the PSU Arjen supplies could damage it but its best to check it.
