colorbar colorbar smd fault

[jason5d]

We have a Chauvet colorbar SMD with a psu fault.

 

Looking inside on the 13a side of the psu.

When I switch on I see a spark leap from a capacitor

to a copper coil, there's also a loud crack.

There's no visible damage throughout the whole light

 

I'm a good solderer, does anyone have thoughts on which

components to swap in the psu as a new one for the colorbar costs

a fair bit.

To be honest Jason, you need to refer it to someone who already knows how to repair switch mode power supplies. They are definitely NOT something to experiment on without all the necessary safety gear in place (current limited supply, mains isolating transformer etc). Sorry not to be more helpful but there is a seriously lethal amount of energy stored in even a small SMPSU and it often remains there even after you've disconnected it from the mains.

Is it a separate psu module, if so just replace the module, Chauvet sell them as spares. DrV is right, they are nasty things to work on, I am experienced at fixing smpsu's but I would still replace the module where it is possible to buy one.
