I plugged my US 120V power adapter in a 220V socket and blew the transformer. After getting a new power cable, my ESX turns on fine, loads up with full text/menus and presets play/light up, but the Valve-tube lights are gone/extremely dim, with NO sound output. Replacing the tubes doesn't help. Any ideas?

I don't know, but running the test procedures in the service manual could give you more information.
