Description

This product is a dated 1994 RCA CD Player. It has 42 distinct parts.

How It Works

The CD Player basic operation comes from laser reading magnetic data encoded on a CD and feeding that information through the circuit board where it is translated to an electrical current which is fed through the jack to a person's headphone.

The components are the input control devices such as the Play, Skip, and Stop buttons; data modifiers such as volume and bass switches; power supply; circuit board and appropriate wires and ribbons; laser tracking assembly which allows movement of laser eye as CD rotates; and CD rotation motor.

Current Status

The CD player currently spins a CD and displays information on the LCD screen, but does not actually read any data from CDs. Speculate that the laser eye has been damaged and does not relay any information to the circuit board.
