SOURCE: I bought panasonic blu-ray dvd

Hi there,

The best way to improve signal strength and quality for digital TV is to upgrade your aerial/antenna and fit a signal amplifier. This is fitted with the aerial and is not to be confused with the signal boosters available from electrical and TV retailers. Boosters are not recommended for use with digital TV and may not even work at all.

I don't fully understand the relationship between your Blu-Ray player and digital signal strength. I presume the problem is with the quality of recordings?

There are many myths surrounding TV aerials. The most common being that an aerial with more elements and which looks like a NASA satellite (X-Beam) is going to give you a better signal. These are often described as "high gain" or "wideband". This is totally false. The best and correct type of aerial to use is simply one that is good quality and correctly matched to the bands of your local transmitter/repeater.

You should also note there is no such thing as a "Digital TV aerial". Shops and installers frequently use this term, but all they are selling is an aerial compatible with a digital signal. From experience, these are usually "wideband" aerials which can pick up all bands from any transmitter, however what this means in practice is that is does not provide good amplification for any band. In my trade, these are referred to a "bacofoil" aerials. "Contract" aerials are also very poor quality. These are usually fitted in new housing developments, bought in bulk and are the cheapest available.

The other essential is to use good quality co-axial cable. The greater the distance between your aerial and your TV the more signal amplification is lost. With poor quality co-axial cable - called "low-loss" - this amplification is further reduced and it is more prone to interference. The best type of co-axial cable is double-screened, copper foil with foam insulation. This costs only a few £/$s extra over a 20m run and is worth every penny. It is also more resistant to moisture penetration which is another common cause of poor signal.

I can give you a mass of further information on this subject. If you are in the UK, I can even check transmitter details and let you know which type of aerial to use and recommend specific products with prices and supplier details. If you are not in the UK, I can still provide further information and examples of products, but you will need to do a little research of your own.

The essential thing is to determine whether you actually a new aerial/cable/amplifier or whether there is some other cause of your poor signal. To determine this, I will need some more details from you regarding your current setup, equipment and how it is connected.

Hope this helps. Please reply to me from within this page if you need further assistance. This is one of my favourite subjects and I don't see many questions about this on FixYa. It would be a pleasure to discuss this in more detail for once!

Regards,
BElectric

Very poor picture quality on LG 42" SMART TV 18 months old


This is probably due to poor quality cable or connections from the aerial. Digital TV needs better quality in both (F connectors and quad shield cable) than analogue TV did.

If all that is good then you may need a better aerial or even a signal amp.

Apex Digital LD4088 LCD TV has horrible quality on cable but fine quality with dvd or ps3


try if you are not, routing signal for comcast via the rear AV jacks--if poor reception that way not the set but the incoming signal.

Most people who are paying for cable or whatever do not complain hard enough--just accept lousy signal and pay for it.

If its poor complain and keep complaining----in most cases there are alternate signal providers eager to jump in.

Cannot get any digital channels since local digital switch over


The official line on this is that you should try and retune again, but there are some Panasonic models with similar model numbers to yours which have been specifically identified as having incompatibility problems with the Freeview retune.

However, your model is definitely not one which appears on the problem list, so it's worth checking that your aerial wasn't misaligned or damaged during the gales last weekend. In addition the Winter Hill transmitter is currently undergoing work until December which will significantly boost the digital signal and give it HDTV capability, so your box may have have been knocked out of kilter if the current digital service was temporarily operating at restricted capacity. Digital signals are by their nature much weaker than analogue tv and if you have a marginal aerial system which has been up for many years and which feeds a number of televisions in the house then it's definitely a good idea to see about upgrading your aerial system.

The difference in actual parts costs between a top spec aerial system and a poor one are surprisingly low, it's also easily possible with careful design and installation to get a better performance with poor parts than you can get with a poorly designed and installed system using top quality parts. One thing does hold true though: a well designed and installed system using poor parts will only last a few years before needing serious attention but a proper job can last up to thirty years.

If you're sure about your aerial system and retuning does not help, then you'll need to contact Panasonic directly. The first web address below will give you their contact number along with a list of Freeview boxes with known retune issues. A second web address which I've given takes you to an excellent Sheffield based tv aerial company which has an incredibly informative website.

Poor picture quality


First of all do you have a HD signal?
these sets are made for HD and most look good when you set the HD box to 1080i , the cheaper sets do not look good with a non HD signal.
check all inputs, dvd, HD air, and component and post which are bad to get more help

EVERYTHING YOU NEED IS IN MY LETTER BELOW.


1. On your remote, find the record mode button; it is near the bottom on the left side. This button sets
the recording speed for the DVR. Faster recording speeds provide higher quality recordings.
2. Look at the display on the front of the machine: it should say XP ( records 1 hour on the disc,)
SP ( 2 hours, ) LP ( 4 hours, ) or EP ( 6 hours. ) You can also set it to record 8 hours on a disc,
but the quality of the recording will be poor.
3 Press the record mode button until the screen displays the recording speed that you want.
4 Note: if the powers fails or the Machine is unplugged, the machine will automatically reset itself to
SP mode.

Trying to make DVR work after 2-17-09


I have been able to record down converted HDTV shows on my Panasonic DMR-EH50 recorder directly to the unit's hard drive and/or directly to a blank DVD-R disc.

I do not know of any DTV converter box that can provide the proper codes to the Panasonic DMR-EH50 to allow recording and scheduling of shows using the unit's built in TV Guide menuing functions (the program recording codes are essentially VCR Plus codes in the USA and VCR Video codes in the UK, and this technology was previously owned by TV Guide/Gemstar but was purchased by Macrovision within the past couple of years.)

When the DMR-EH50 is hooked up to standard RG-59/U coaxial TV cable, the cable company provides the specific VCR Plus recording codes, as well as auto setting the time and date information required for the TV Guide recording schedule menus. The VCR Plus recording codes are sent via the cable company through the coaxial cable to the end consumer's recording device. Since Gemstar's VCR-Plus patents are now owned by Macrovision, I am not sure of how this works (or will work) for non-cable/non-satellite customers or if such codes will be made available by Macrovision to record shows when one receives HDTV signals (or down converted DTV signals) from an over-the-air antenna.

Though the DMR-EH50 recorder can only record at Standard Definition (SD) broadcast resolutions, I connect the DMR-EH50 to my High Definition TV using the three progressive scan YPBPR output cables and switch my HD-TV into the YPBPR mode when I want to watch shows from the DMR-EH50.

YPBPR are the analog video signals carried by three color coded component video cables. The green cable carries the Y signal; the blue cable carries the PB signal; and the red cable carries the PR signal. The added benefit of using the YPBPR hookup is that you can 'up convert' a standard DVD disc (non HD Blu-Ray disc) in progressive scan mode to somethin akin to 720p resolution using the DM-EH50 (or any other progressive scan DVD player) to get a better quality image on your HD-TV.

Visually speaking, the same appears to hold true for playback of programs recorded on the DMR-EH50's hard drive even though down converted via the DTV converter box, and when played back on an HD-TV using the YPBPR progressive scan cabling hookup.

I also been able to successfully record programs from the DTV converter box to the DMR-EH50 recorder in both 16:9 wide screen and 4:3 normal aspect ratios, but again only in Standard Definition quality.

For NTSC and PAL formats, the correct aspect ratios for any particular TV (the rectangular height and width of your output resolution for a TV screen) can usually be setup correctly for most any DTV converter box by going carefully through the menus on the converter box. Though the converted DTV often will yield 'better looking TV' than cable, it's certainly not high definition however, as the purpose of any DTV converter box is * not * to yield a High Definition digital TV signal but a lower quality Standard Definition signal for viewing on older SD-TVs.

We must remember that what is happening here is that (by NTSC USA standards), we are transcoding (i.e., down converting) an over the air 1920 x 1080p (progressive scan) High Definition digital broadcast signal, captured by your over the air antenna, back to a Standard Definition 720 x 480 resolution analog broadcast signal (the 720 x 480 resolution is a 4:3 aspect ratio.)

Hope this helps a little -
