Question about Panasonic SC-HT40 System

Picture problems Installed suround sound system and TV has snowy picture when reciever is turned on. There is no picture quality loss playing a DVD just when the satelite reciever and suround recievers are on. the TV is also a Panasonic 5 yrs old......could this be an unshielded cable problem? i dont understand how only the satelite picture reception is degraded.

    the subwoofer is down on the floor 3-4' from the satelite reciever and the first fix i tried was to move the speakers away from it. there is no effect by the magnets in the speakers when the reciever is off, this is where the confusion stems from. the degraded picture only happens when there is power to the surround reciever.

    We are having a picture problem on the lower channel numbers, 2, 3 ,4, not as noticeable on the higher channels Tried moving the receiver and speakers, but it didn't solve the problem. Using a 42 inch plasma television, and connected to cable.

This could be an unshielded cable problem. Also magnetisam from speaker(s)(i.e. subwoofer) could affect signal from satelite antenna, or could affect satelite receiver if it's near.

    Yes, it was the cable. Even then I move it around behind the TV to get a great picture. Also I changed the RCA dvd/vcr line out cable and that improved the sound(bad cord!). Thanks!

How to set up a home theatre system ?

Considering a home theatre system, you will have to connect both the audio and the video cables of your home theatre system to your DVD player, so let us first start with the connection of the audio cable.

Step 1:Firstly you must find the digital output point on the back of your DVD player. It will be labelled as "COAXIAL" or "OPTICAL". Some of the DVD players may have both the Coaxial and the Optical output. In that case you must connect only either of them. Both the outputs require different kind of output cable. The Coaxial output uses a standard shielded RCA cable which is plugs in an RCA jack which is labeled "COAXIAL DIGITAL". The Optical output uses a fiber-optic cable which has a square shaped connector at both the ends. Both the outputs deliver almost the same quality of sound but the Optical cable sometimes allows us to prevent ground loops. Both these digital cables do not carry any video signals. Now connect either of these to the digital audio input which is at the rear of your reciever.

Step 2:Now you must connect the video cables. Before you start doing that you must decide if you want to connect the video cables through the A/V reciever and then connect it to the TV or just directly connect it to the TV. By connecting the wires to the A/V reciever and then to the TV usind two separate cables has its advantages in which you find convenience if you want to switch the reciever to watch a DVD and also you will be able to see the on-screen menu on your TV. By directly connecting the cable to the TV you will find it easier but again you would not be able to see the on-screen menu.

Most of the DVD players will have three video outputs. Connect all three of them inorder to recieve maximum video clarity from a DVD. It is necessary to have component outputs on your TV and/or your AM reciever inorder to connect all the three video outputs. In case you dont have an component output then you will have to connect only one s-video cable to your TV input. This s-video cable is a single cable with a multi pin plug. In case there is an component output for your TV. then you will require three cables(RCA) which have different colour codes(which are sometimes binded togethr). the colours are usualy Red , Green and White. Using the component output gives you the best video quality next to which is using the s-video output. The DVD player may also have an HDMI or DVI connectors. These help in maintaining the video in its digital form rather than converting it to anolog form.

Step 3: Make sure you dont turn the volume of your surround sound too high in which case any one of the speakers might call attention to themselves. In other words, in case the volume of the surround sound is too high then sometimes one of the speakers on your rear may call your attention separately. Hence it is recomended to keep the volume in its optimum level. Many of you might even wonder if the surround system is actually functioning properly until you experiance an of-screen sound such as a phone ringing at the backround or the sound o thunder in case of a rainstorm . Hence you must know that a surround system is not for loud noises and rather to experiance a three dimensional environment in between a movie.

There are certain things which you can do inorder to experiance a better feel using your surround sound system. Few of them are as follows,

1. It is advisable to get a test DVD which will help you adjust the surround sound levels and make maximum use of the system. For instance get a Sound and Vision magazine home theatre tune up DVD. IT will help you in maximizing the effects of the system.

2. Always remember to keep the central channel speakers setting at low. In case the setting is high then there is a loss of clarity of speech.

3. Try changing the seating arangements around the surround speaker system. Sometimes you might feel better audio quality at certain positions.

4. Always keep the brightness of the TV on optimum range. This is better for viewing more particular details in the picture quality as well as increases the life of the TV. Hence high brightness will reduce the life of the TV as well as give u less details on the picture being viewed.

5. Always have the volume of the sub-woofer at medium when you play music and then gradually increase it to how much ever necessary.

My BD530 player doesn't play all movies clearly. Some come cover good others re all snowy

When properly connected to a High Definition display or TV, Blu-Ray Disks (BD) should play crystal clearly. Inserting an old "non-Blu-Ray" disk (or the original "DVD") in the Blu-Ray player will display a comparatively "fuzzy" picture. This is the difference between High Definition and Standard Definition. A "BD player" can not "upgrade" the picture quality on DVDs to that of a BD or High Definition picture.

Rent, purchase or choose Blu-Ray Disks (BD) whenever a choice is offered to view the High Definition version of a movie or video. Selecting the DVD version will provide the lower quality or Standard Definition version of the same movie or video.

Check the covers or disk itself to determine if the movie or video is in DVD or BD format. That will tell you what you can expect for picture quality.

I hope this helps & good luck! Please rate my reply - thank you.

I've bought a panasonic sound surround dvd player and want to link it to a sky+ box and tv so that sky will play in sound surround. Can you advise on the wiring configuration please?

look at the back of your tv does it have a audio out RCA jack?
it should do plug in the surround sound into that using RCA cables

if your tv does not have audio out RCA jack then you can

get a adapter which makes scart connectors turn into RCA jacks get that off ebay

plug the yellow line to the tv and connect the red and white to suround sound
but with this there are a few problems sound will only come out when surround sound is turned on and skys sound will never play out the tv
if you switch to a PS3 or something it will not play suround sound

yuo best option is the RCA plugs in the back of the tv

because you have not written the model number of the tv or the suround sound i cant help any further

yes it could ba the cable itself even, but i suspect more the tuner circuit or tuner itself may have bad solder connections. Here is another test for you to try, plug another dvd or vcr, or xbox etc. into the back, using one odf the inputs. See if this works like the built in dvd. if so it will be more likely bad connections in the tuner or surrounding circuit. good luck.
