There is also a small PCB on the lower right that holds the circuits for the phones output.
So, what's inside the Denver DVD-141 DVD-player? It seems to be almost the same player as the EuroLine 6642M.
All these pictures are from my friends Denver DVD-141, so yours may not look exactly the same inside.

This is the inside of the Denver DVD-141. DVD-drive to the left, a board for the
IC's in the middle and the power supply board to the right. At the top (a bit to
the left) there is a
small card for the SCART-socket. There is also a small PCB on the lower right that holds the circuits for the phones output. |
The PCB that hosts all the IC's in the DVD-141 looks like this:

PCB of the Denver DVD-141. |
Here is a list of components and their function on the board above:
| IC | Function |
|---|---|
| MediaTek MT1369AE | DVD-Player Servo/Decoder/µP chip |
| AVS Technology AV3168 | NTSC/PAL Video encoder |
| MediaTek MT1336E | DVD-Player RF Amplifier chip |
| 2 x ESMT M12L16161A-7T | 512K x 16Bit x 2Banks Synchronous DRAM (143 MHz) |
| SST 39VF080 | 8Mbit (1M x 8) Flash memory |
| ROHM BA5954FP | CD/DVD-ROM Motor/Actuator Driver |
| Cirrus Logic CS4340-KS | 24-Bit, 96-KHz Stereo D/A Converter for Audio |
| ST C4558 | Wide Bandwidth Bipolar Operational Amplifiers |
| Atmel 24C02N | 256x8 Serial EEPROM |
If anyone has the datasheets for the MediaTek or ROHM BA5954FP circuits, it would be great if you could send them to me.
The DVD-drive is not a standard IDE DVD-drive as it is in many DVD players. It seems to be similair as the ones in the 6620/6650 / 6632/6652 players. This drive was marked with http://www.asatech.cc, which seems to be the manufacturers of the drive.

If you look closer at the DVD-drive, there seems to be very few IC's on the drive itself. So all the IC's needed to control the drive is located on the big IC board.
 |
Here is a closer look at the DVD head. I have taken this picture with the camera located right over the SCART-socket. |
 |
This is another photo of the DVD head from a different angle. |
Not much to say, it's a power supply with all the things that a power supply usually have:
 |
The PS in the Denver DVD-141. To the right you can see the small PCB that holds the circuits for the phones output. |
There is also a small PCB that contains the SCART-socket.
 |
The SCART has stereo audio output and a choice of RGB or Composite video output (RGB or composite is chosen in the setup menu of the player). |
If anyone has any more information about the hardware in the Denver DVD-141, or can tell me if I have made any errors on this page, please contact me.
