No sound and picture does not fit tv screen

You can certainly purchase a cable or an adaptor to connect the speakers to almost anything - this however is not the issue - z5300 computer speakers have an impedance of 8 ohms, whereas most home theatre systems will be set up to use speakers with an impedance of 4 Ohms or 6 ohms or 8 ohms - using the wrong type in the wrong configuration is very likely to result in damage. Also the speakers contain their own amplifier, and are designed to accept an input that has not been amplified to speaker levels before - most tv/dvd audio output will be amplified, depending on the model, so will almost certainly destroy your speakers unless you have a low amplification output on your tv/dvd. If you post back with the make and model of your tv and dvd player, hopefully i can find the necessary info to describe how you could make the connection if it is possible. Logitech says; "Logitech speakers are powered speakers and are designed to be used with a home computer. However, it is still possible to connect your speakers to many other devices. You can connect any Logitech speaker to any device that has a pre-amp mini-headphone jack. Home amplifiers will normally contain a standard ¼" headphone jack. You'll need to purchase a ¼" to 1/8th" adapter to connect your Logitech speakers to a home amplifier. Note: Under no circumstances should you connect your Logitech speaker system to an amplified output such as the rear outputs of a home amplifier. Doing so may cause damage to your Logitech speakers as well as your home amplifier." Hope this helps - please post back with details :)

SOURCE: No sound

What you may have is a cold solder joint in the audio section of the TV. To find this problem you will need a schematic, and mutlimeter, and a small audio signal finder. If you have a cold solder joint look in the audio section of the TV (The schematic will help you find it). use the audio signal finder to locat the position where the sound drops out, and then use the multimeter to find if the proper voltages are on the audio output components. This troubleshooting implies that you have the bacground in electronics, if you do not have a background in electronics I would suggest that you take the set to a qualified TV repair shop.

I encountered the same thing using the HDMI interface on my new TWC cable box (Motorola DCX-3200). After a little bit of research, I finally fixed it by changing the digital audio mode in the cable box using this procedure:

1. Be sure the TV is on and connected to the cable box.
2. Using the cable box remote turn power OFF.
3. Immediately press the MENU key on the remote. The USER SETTINGS menu should appear on the TV screen.
4. Select the ADDITIONAL HDMI SETTINGS >>> menu item.
5. The ADDITIONAL HDMI SETTINGS menu will appear.
6. Scroll to the AUDIO OUTPUT item and select this.
7. Change the setting from AUTO to L-PCM.
8. Return to the main page
9. Using the remote, cycle power OFF.
10. When the cable box is turned on again, you should be good to go.

I realize these instructions are specific to the DCX-3200, but there may be a similar setup option available in your cable box as well.

The problem here is that the cable box is by default configured to use Dolby Digital audio, which requires an additional 10dB of headroom to deal with the boosted LFE channel. If the cable operator hasn't taken pains to set the system up correctly (and most haven't, apparently), the digital audio level sent on the HDMI interface will be approximately 11dB down from normal analog line levels on the HDTV channels. Changing to straight linear PCM sets the TV receiver audio level on the HDTV channels to match the levels on the non-HD channels.

The only problem with this fix is that if you intend to feed a Home Theater receiver that uses Dolby Digital processing with the cable box output you will lose the Dolby encoding feature and be forced into straight 2-channel stereo. For a simple installation like mine where I'm just feeding the TV, this fix works fine. If you have a more complex setup that takes advantage of Dolby Digital features (when it's available in program material), you may have to live with the problem.

For a technical reference on why this happens, see http://www.megahz.com/specimages/Dolby/LM100%20Cable%20App%20Note%2011-05.pdf

Hope this is useful.
