Faulty Acme dynamo 250 mirror not moving !

[hiltonent]

Hi everyone need soom advice one of my acme dynamo 250 mirror is not moving , light comes on etc but mirror dont move ,
I took the board out of 1 to try it on my other working dynamo and that mirror is now not moving ive also tried the motor to see if thats faulty but its working fine so im pretty sure i need another board or some to see if they can repair it... anyone know where i can get another board or someone to have a look cheers

Sounds like a chip failure, but could be dry joints on the board as can't see any burnouts.
If you can work out the pin readout to the motor loom and see if you get voltage when powered up it would narrow it down. Chauvet should offer a spares service if its the chip. But don't attempt if you're unsure. EBay sometimes comes up trumps if you're after a complete board.

Hope this helps

Been looking for a board but no luck :( been to a local dj shop they said a new board from prolight will be around £60 which is way to high

With the unit powered on and the motor connected is there resistance if you try to move the mirror?

No cant feel anything , Once i plug in my working board from my other working dynamo it comes on and works perfect .

If you can get the writeing off the two chips where it says U5 that looks to be the stepper driver. If you can get a like for like a quick solder of a new one and it should work again unless its a worse problem!
