Serious issue: Enormous interference from Vero4K PSU

The Vero 4K has been tested and certified. Such an issue would have been noticed before by other users if it was commonplace. I suspect that your issue lies with the power supply. Occasionally these can go faulty (bad coil), or get damaged in transit. A user had interference here and a replacement power supply resolved the issue: Vero 4k power supply problems.

If you send me your order # we’ll get you a replacement PSU out.
I assume that you have not tested with another 5V, 2A PSU?
