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 binary 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 CD Player functions are as follows: the "Circuit Board" receives the electricity that the batteries provide. The "Circuit Board" regulates how the electricity is used, and what parts it is supplied to at all times, so that the player functions correctly. When the "Laser Motor" is receiving power, it spins the gears that interact with the "Brass Screw", which causes the "Laser Housing" to slide back and forth along the two "Stainless Steel Rods". When the "CD Rotation Motor" is receiving power, the disc spins around it at a variable speed so that it can be read by the "Laser Eye" from the middle outward.
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.
Parts
