Question about Panasonic SC-HT720 System

Dvd movie playback

During playback of any dvd movie, the system sometimes stops suddenly and returns to the blue 'start up' screen. Repair technicians claim the problem is possibly a thermal(overheating) issue but can not identify which component.

Techies may be right- the only way to find out is to get a cool breeze around the unit- a fan say- whilst in operation.

Denon dvd player freezes in the same place on certain dvd's also sometimes willnot start to play disc unless re-inserted several times. Model D-M51DVS


sounds like its stoping during layer switch, if the player is old its needs to be cleaned. its best to clean it once every 20hrs or so. if you do not have a disk cleaner you should go buy one first. if the player is new return it and get the best dvd player you can buy for any amount the toshiba xde. this player is phenomenal, the best you will be amazed. no i dont work for toshiba but ever since they started making hd dvd players(i know they stopped)there players have become the best. trust me if you dont think so just return it. no harm done. if you want a blu-ray get ps3 I dont like them either but i have to admit after buying (for movies only)my third blu-ray player it is by far the best one. almost as good as the toshiba on standard dvd playback but not quite. good luck.

I have a magnzvox MPDD845 8.5" TFT Monitor Portable DVD Player


The sound you are hearing is the lens attempting to focus. Since it seems to recover, this could be an alignment problem or just a connection problem. Without seeing the waveforms of the tracking circuit, I can not say for sure. If this is a new unit, return it for warranty exchange or repair.

LG LRA-750 goes to PAUSE during playback.


Hi Andy12345,

It sound like the LRA-750 processor board has developed a fault, it may be in its remote IR sensor circuit or the main micro-controller. If it's still under warranty I'd take it back the the store where you purchased it and get it exchanged. Some LG items have a warranty of up to 3 years, check yours on-line, at the LG website.

Regards,

DVD Freezes during playback


it might be that you are playing a dual layer dvd in the player. The player needs to focus on the second layer of the movie, and that might be why the dvd freezes. Leave it there for a while and the dvd should continue if it is this situation.

DVD player stops frequently during playback


Yes first try to clean the laser with a lens cleaner. If that does not work you can then try to take off the cover and clean off the lens manually with a slightly damp cotton swab and alcohol. After that turn around the swab and dry the lens with the dry side of the swab. If that doesnt work then it Probably is out of alighnment or the spindle motor is bad, and is most likly not worth the bench charge for an estimate.

Freezing?


any commercial films are written to what's known as dual-layer DVD discs, which are like two DVDs sandwiched together. Movie studios try to pack as much cool stuff as they can onto a DVD, so by the time you add movie trailers, documentaries, and other special features, the amount of space necessary far exceeds the 4.7GB capacity of a regular DVD disc. Using a dual-layer disc expands the capacity to 9.4GB, which is enough to hold the movie and many extras, depending on how long the film is. What you seem to be experiencing is a problem related to the DVD player changing layers (when it must adjust the focus of the laser to read the second layer of the disc), which is usually indicated by a brief pause during playback. In the early days of DVD, many players had difficulty during the layer change, which could cause the DVD player to lock up during playback. In other cases, a badly formatted or damaged disc could be the culprit, so you should check the condition of the DVDs that are giving you problems. Since you mentioned that sometimes they work, your problem could stem from a scratch or a fingerprint. But, if the condition of the DVD is flawless, you may have to consider getting your DVD player repaired, replaced, or exchanged (since you mentioned it was new). Since it is a portable DVD player, you may want to try running the DVD player when it is plugged into an AC receptacle. This will at least rule out any relationship to the battery, though a remote possibility. But, portable devices do strange things when its battery is low.
