Possible Causes

Tripped circuit breaker, Faulty power cord, Blown internal fuse, Defective AC filter board

How to Fix / Troubleshooting

Safety first: Before assuming an internal fault, verify the outlet. Do not open the unit while it is plugged in.

Steps:

  • Outlet test: Plug another device into the same outlet to confirm power. Reset any tripped breakers or GFCI outlets.
  • Inspect power cord: Check the Cavin cord for visible damage. If damaged, replace the cord rather than attempting to repair it.
  • Internal fuse: With the unit unplugged, remove the rear panel and look for an AC filter or small board where the power cord connects. Check for a replaceable fuse. If blown, investigate for shorts before replacing.

Repair: Replace a blown fuse only with the same rating if no obvious short is found. If the fuse blows again or the AC filter board is burnt, replace the AC filter/power board or main control board as appropriate.
