How to troubleshoot a ProScan PSB3787W with no power?
- DDr. Kimberly Gordon MDAug 6, 2025
If your ProScan Speaker System has no power, first ensure the adapter is securely connected to both the soundbar and the wall outlet. If it's still not powering on, the soundbar might be in power-off mode. Try pressing and holding the POWER/SOURCE button on the soundbar or pressing the power button on the remote control to turn it on.
