Review NaN of
, from Vail, Colorado, USA
Price Paid:
$0.00 Summary: Got one of these into the shop for repair... "Wont read DVDs" says the customer. After doing the usual lens-clean it still won't read a DVD so I decided to check the internet for information. ACK! Ok, so it'll never read DVDs.
I've noticed that the C-Cube (LSI-Logic) ZiVA-4.1 decoder/display chip does get hot enough to fry an egg on (LSI says the chip should have a heatsink on it to prevent skips and errors...hmmm...). But, as the ziva is used in several other DVD systems, I doubt it's the chipset thats causing the "won't read" issue.
After some more diagnosis I've determined that there seems to be an issue with the laser head. The unit will read an MP3 cd just fine but it seems to have a real issue with DVDs... I guess this could be the root-cause of all the problems we've seen with this unit.
Upon reflection I would guess the problem could lie in the differences in AC power specifications between the US and other countries. In the US we use 110v/60hz power while just about everywhere else uses 220v/50hz power. Perhaps the power supply board has a bug in it's design for US power? Strengths: Does have a lot of features thanks to the ZiVA chipset which does the following:
Full disc playback compatibility: DVD, Chaoji VCD, VCD, and CD-DA.
Embedded 10-bit, 4-DAC digital video encoder outputs YCbCr, RGB + composite sync (EuroSCART), or CVBS/S-video.
Supports NTSC, PAL, PAL-M, PAL-N, PAL-Nc, and PAL-60 (Q-PAL).
Full NTSC and PAL decoding.
Dedicated 50-MIPS audio DSP delivering 3D audio, (including Spatializer™ N-2-2), DVD-Audio, Dolby Pro Logic™ decoding, Bass Redirection, RealSonic audio technology.
Dedicated Dolby Digital, MPEG-2 5.1- channel decoders.
MP3 Decoder.
DTS digital out.
2/4-bits per pixel OSD.
Zoom and fade-in/-out functions for still and motion pictures. Weaknesses: Great components assembled by trained apes. Even the Apex unit (essentially a PC DVD rom connected via IDE to what ammounts to a PCI video card) outclasses the DVD-711 in just about every way. Similar Products Used: Sony ES gear, Denon, JVC, Panasonic, and countless others.
