Question about Cyberhome CH-DVD 300 DVD Player

3 Answers

Freezing? The DVD player will play some DVDs and not others. It would play and then the screen will turn blue and then play again. I tried cleaning the disc but that does not work. Sometimes, it would not play a new DVD.

Hi This is a common fault, and unfortunately, there is only a slim chance it can be economically repaired. I've seen it caused by an over-heating video processor I.C., but also a weak laser, where basically the laser looses it's place and the video processor "hangs" on the last frame of proper video. The good news about that, is that a dirty lense can cause the same symptom as a week laser due to trying to read through dust, so a cleaning could possibly clear up your problem. Now, it's a long shot, but there is also another scenario we often see. If you have an older tv, without A/V inputs, most people connect their DVD to the A/V inputs on their VCR, and change the source on the VCR to AUX. This works fine on some DVD discs that are not big budget films, so it will play some discs perfectly. As soon as you put in your favourite "Terminator" DVD, what you get is a perfect picture for a while then blue screen, then normal picture etc.This is due to copy protection built into the DVD. If you are indeed connected through a VCR, and your tv only has RF input, then you can buy an RF modulator from your local electronics store, and connect through it instead of the VCR. Good Luck!

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.

Wont read some discs

This is a indicator that the laser pickup assembly is failing. Try a DVD cleaning kit to clean the laser lens, if no change it is far cheaper to replace the player than have it repaired.
