Hello rqromero2,

Picture quality problems (such as lines, fuzzy image, or wrong colors)Check the cables and connections:
  1. Make sure that cable connections are securely fastened to the connectors and try reaseating the connectors. If connecting a device using component cables, make sure all three color-coded cables are connected correctly into the corresponding connectors.
  2. Check the condition and length of the cables. Cables that are longer than 3 meters (10 feet), become more susceptible to promoting signal degredation (small dots "sparkling" on the screen and image ghosting). Cables that have been bent or pinched may also cause picture quality problems. Replace the cable or try a different cable type.
    Press the CH button to display a different channel. Picture quality problems on a single channel or on all channels may be caused by the TV station signal (antenna) or the cable signal source.
  3. Make sure that the image quality issue is not coming from your source signal.
    For example: if the image quality issues occur while viewing TV, switch the source to a DVD player to see if the image quality problems go away.
    If selecting a different input source (using the remote control) causes the problem to go away, troubleshoot the source device causing the problem - adjust aerial antennas, call the cable company for assistance, and .
    If a picture quality problem occurs on all sources, the TV or its settings may be the cause of the problem. NOTE: Higher resolution TVs will make it much easier to view signal problems coming from source signals - especially TV signals. For example, if your TV cable company experiences heavy load on their system, you may be able to detect small miscolored squares that briefly scatter across the screen (macro-blocking). On a smaller standard TV, this type of quality problem is much less noticeable on a standard TV, but can become very annoying when viewed with greater detail.
  4. Open OSD to adjust the picture:
    Press the Menu button to open the OSD. Select the Picture menu and adjust the image as needed. 
    If you cannot adjust the TV to fix the problem, reset the settings from the OSD to see if the problem goes away.
  5. Unplug the TV from its power source. With the power cord unplugged, press and hold the power button for five seconds. Turn on the TV. If the image quality problems still exists across all types of signal sources, the TV should be serviced.

If this dosent solve your problem, letus know and we will find another solution,

Black and white picture with red lines vibrating with sound.

More info would be nice. Are you using HDMI or Component cables. If it is component cables (red, blue, green for video white and red for audio) Check your red and blue connection. Green alone will give you a black and white picture.
If you are using an HDMI cable, replace the cable to see if this changes anything or if you have another tv swap cables to see if problem stays with tv or moves to another tv.

I have a samsung sp42q2hl, which on the front of the tv say's it is a hdtv ready, and yet i cannot watch high defenition images or movies, also there is no hdmi inlet at the back so i'm not sure how you...

Use component to connect this will give yu HD picture,
On the back of the set you will see A group of 5 phono sockets Blue, Green, Red, These carry picture,

Then Red, White, these carry stereo sound.
Component video 0831d.gif
Component-video cable b.gif
Component video improves the picture quality even more by not only separating the color from the black-and-white portions of the picture but by further splitting the color information into two color-difference signals. When the picture signal is split up in this way, you get an unfiltered, uninterrupted image, with better resolution and greatly improved color saturation. And this is why component video is the predominant method of hookup from HDTV set-top decoders to HDTVs.

So this is how your set can produce HD picture from Hd source.

Hello there. Sounds like you have a frustrating problem. What I hear you saying is your television is not making any sound at all. Not even fuzz. Because your picture is also effected then that narrows down the scope of causes of the problem. Some things that can blow out the speakers and the tuner are: Improper amperage, improper polarity, a lightning strike, an improperly added tuning device, and a few other things like dropping the television. If you suspect one of the above then I recommend checking our online list of repair technicians in your area.
If this does not help then please give me your make and medel # for your television and list what kind of service (cable, satellite, etc.) and what other devices you have connected and I can get more specific.
Thanks and good luck.

Poor picture quality on my samsung HD TV

Hey xf1racer,

Based on the description that you provided, it sounds like you are using a bundled composite video cable to connect your cable box and TV. Composite video cables generally consist of three color-coded cables: one yellow, one red and one white. While the yellow cable is typically used to transmit the video signal to your TV, the red and white cables transmit the right and left audio channels respectively.

Red/green/blue bundled cables however, are often referred to as component video cables - each of the three colored cables is used to transmit a different portion of the same video image from one device to another, and require a second separate cable (typically red/white) to transmit an audio signal.

The primary benefit of using component over composite cabling is that many users may report a cleaner, more brilliant image on their TV as a result. Please keep in mind however that this is not a guarantee that changing from your current set-up to component cables will improve the picture quality on your TV, as picture quality is often based as much on personal preference as it is the actual configuration and settings of the equipment used.

Additionally, many retailers may suggest changing your current configuration to one using HDMI cables instead to improve picture quality even further. Unlike composite and component cables, standard coaxial cables, and S-Video cables which transmit analog signals, HDMI cables are designed to instead transmit uncompressed digital signals. This typically means that more information is available for your TV to process in terms of color hue, color intensity, as well as image resolution. Again, remember that any perceived improvements will be based on both personal preference as well as your home theater configuration.

Should you have any questions or lingering doubts, I would strongly suggest speaking with a Magnolia Home Theater agent at your local Best Buy™ store for more information. Most stores will have similar TV's on display using more than one type of connection, and sales associates are always able to provide additional suggestions if desired.

Hope this helps you out.

Go Ahead. Use Us.

Snowy picture


A snowy video indicates that your input signal is relatively weak. On the other hand, a noisy picture is when there are too much interference is super imposing on the video.

Snowy picture comes about when the signal coming in the RF INput (Ant/Cable) at the back of the unit is below a certain level. If this is the case, then it is not a problem with your TV but rather your aerial (antenna) or the cable from your provider. A way to verify that it is the ant/cable that is the cause and not a defective TV/tuner is to hook up an old VCR set to Ch. 3 or 4 to the RF IN of your TV using a short 75 ohms coaxial cable terminated at both ends with FP-5 connector. Play a known clear good tape and set your TV to Ch. 3 or 4 as the case maybe. If the picture is relatively clearer, better, then you have just confirmed that it is indeed your aerial or your cable (provider) that needs looking into. If on the other hand, the VCR signal is also snowy then chances are that you have a problem with the input stage of your TV including possibly your tuner.

For your aerial problem, antenna orientation or replacing with a higher gain antenna might help solve the snowy signal. For your cable problem, you have to call-in for service from your cable provider. If it is a TV problem, your best course would be to seek the services of a qualified TV technician since this involve electronic circuitry analysis, diagnosis and possible component replacements.

Additionally, you may try looking for any loose connection, loose grounding, broken wire or anything out of the ordinary in your connections.

Hope that this be of some help/idea. Pls post back how things turned out or should you need additional information.

Good luck and kind regards.

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.
