Lexus rx330 Radio has power but no sound?

It is buried behind/under the right rear seat and the rear luggage compartment area. There are two connectors. The test will show 12 volts on two white wires in the larger plug. If you getting power and grounds and you still have no sound out of the radio and all the other functions of the radio light up normally and work normally you're probably looking at a bad amplifier. This particular Mark Levinson system had issues with the amplifier's. You need to have it sent out and repaired. I normally recommend that the radio head unit and amplifier sent out as a pair so that they can be tested together.

This details will help.Thanks.
