Background and Identification
A DVD player is a device that plays DVDs produced under the DVD-Video and DVD-Audio technical standards, which are two different and incompatible standards. Some DVD players are also able to play audio CDs. DVD players are generally connected to a television so users can view the DVD’s content. DVDs can contain movies, TV shows, or other content. The first DVD player was developed in 1997 by Sony Corporation in Japan in partnership with Pacific Digital Company in the United States.
Regardless of the specific make and model: all devices of this type contain an optical disc drive that has the following two major sub-components:
- a motor with a spindle assembly to hold and rotate the disc
- a laser assembly that moves radially and reads the disc (from the center outwards).
One of CyberHome’s most popular DVD player models is the CH-DVD 300, which reads DVDs, CDs, and MP3s that are 12 cm and 8 cm in diameter. This model features 24-bit audio Digital to Analog Conversion (DAC), a 90 dB Audio Signal to Noise Ratio (SNR), and an 80 dB DVD Dynamic Range.
CyberHome DVD players include the name “CyberHome” in the lower left-hand corner of the device’s front face. The player’s model name is generally printed underneath the “CyberHome” name.
The most common DVD player problem is generally trouble loading or reading disks. If the player is having trouble loading or reading discs, the problem is almost always mechanical. Try these quick tricks:
- Nudge or slide the laser assembly back and forth in its track, using your finger or some sort of plastic tools like a spudger or a pen cap
- clean the laser lens (with 90% isopropyl alcohol and a q-tip).
