Chauvet Strike 1

The Chauvet STRIKE 1 is an outdoor-ready blinder powered by an intense 230 W warm white LED source. It is also an awesome strobe and a wide area floodlight. Its IP rated fan keeps it cool enough for use as a wash while IP rated direct power and DMX connections eliminate undesirable whips. An emulated “amber shift” warms the Colour Temperature of the light as it dims to mimic incandescent lights perfectly.

Known Issues

Symptom or Problem Encountered

Non functioning light. No display on the control panel.

I was told it's the PSU. It wasn't.

Causes

Shorted diode on controller board.

Solutions

Replace a £0.60 diode.

Disassembly Notes

These are outdoor lights and the cap head screws may have corrosion in the aluminium housing. Use penetrating oil if possible.

Remove the three cap head screws holding the display and control panel housing taking care to retain the washers.

The panel assembly will lift out. If the fault is as described the connectors can remain undisturbed. Some of the zip ties had sharp pointy ends, so take care with those.

Diagnosis

Without mains power connected check for a short across D2, adjacent to the inductor.

If short, lift one side of the diode (or remove it completely) and check the diode and the solder pads. In my case the short on the board went away.

If that's not the the fault, plug in the mains power and check the DC voltage into the board. The voltage to the board is 63V DC.

Replacing the diode fixed the fault. But as to what caused the failure in the first place?

I repaired two of these with identical faults.
