Chauvet Strike 1

This is a template page for creating new pages for devices, troubleshooting them, part lists, and other repair info.

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.

Diagnosis
Without power connected check for a short across D2, adjacent to the inductor and check again.

If short lift on side of the diode and check again. In my case the shirt went away, as this diode was short.

The voltage to the board is 63V.

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.
