Frequently Asked Questions - DHT230NT DAEWOO

My Daewoo DHT230NT player does not turn on. What should I do?

Check that the power cord is properly plugged in and the outlet works. Make sure the on/off switch is in the ON position.

Why is there no picture on the TV?

Check that the TV is on and set to the correct AV input. Ensure the video cables (composite, S-Video, or component) are properly connected and not damaged.

The sound does not work, what should I check?

Check that the TV or amplifier is set to the correct audio input. Ensure the audio cables are connected correctly (L/R) and the volume is not at minimum.

The player does not accept a DVD, what should I do?

Check that the disc is compatible (DVD, VCD, CD...) and that it is not scratched or dirty. Clean the disc with a soft cloth from the center outward. Ensure the disc's region code matches the player (region 4 for Mexico).

The remote control does not work, how to fix it?

Check that the batteries are installed correctly (AAA type) and are new. Point the remote at the sensor within 7 meters and remove any obstacles. If the problem persists, replace the batteries.

How to use the Karaoke function?

Plug a microphone into the front MIC jack. Press the OK button on the remote to activate Karaoke mode. Adjust the microphone volume using the MIC VOL knob on the front panel.

How to change the subtitle or audio language?

During DVD playback, press the 'LANG' or 'SUBTITLE' button on the remote repeatedly to select the available language. Note that not all discs offer multiple languages.

The player makes a humming or crackling sound, is this normal?

A slight hum may come from the transformer. If the sound is distorted, check speaker connections and keep audio cables away from power cables. If the problem persists, contact a technician.

Can I play MP3 or JPEG files on this player?

Yes, the Daewoo DHT230NT supports CD-R/RW containing MP3 and JPEG files. Insert the disc, the menu appears. Use the directional keys to navigate and select files.

ESS66x8-04 REV-A1 ES66x8 + SANYO DV34 PICKUP + OUTPUT

Background

This DVD design is based on ESS Vibrio-II ES68x single chip DVD mpo and servo processor. The ES68x is built upon ESS proven Programmable Multimedia Processor architecture with integrated servo DSP. A complete DVD design using ES68x RF-Amp can support all major popular optical pickup hooks. With ES68x unity memory architecture, the whole system memory is reduced to a minimum. ES68x provides the best price performance DVD solution in the industry.

System Clock Requirement

ES686 requires a 27MHz clock to operate. This 27MHz can either be generated externally and feed into pin 3 and pin 4 or thru a 27MHz crystal attached to pin 2 and 3. This 27MHz will be used for all video processing reference. In addition, internal multiplier will generate a much higher operating frequency for the internal RISC DSP code to operate. Audio clock is generated from ES686 by its internal PLL circuitry.

SDRAM Usage

E66x8 support the use of higher density 4Mx16 SDRAM. A single of 4Mx16 SDRAM is sufficient for the whole system to operate.
