When i connect cable to the cable tv port the picture is snowy. I verified that the cable signal was good by connecting another tv and its fine. I did get the samsung to work but we had to go through the cable box using Audio visual cables and go through the tv AV portsand setting(AV1) but now we dont have the cable box, just basic cable service.

1. You are not on the right input for the signaling device: Verify which input number (or type ie HDMI/component/video/Cable) your device is connecting to and tune to that input.
2. The signaling device is not powered on. Verify it is on and the cable is properly seated into device and TV.
3. The cable is bad. Try a different cable or use alternate type of connection.
4. The specific input port on the TV is bad. Move the connecting cable to a different port (ie from HDMI 1 to HDMI 2) and tune the TV to that input.
If you are using an Over the Air signal (OTA) with rabbit ears or and antenna use the TV menu to run an auto tuning scan of your local stations.
If you are using a tuning box (cable/satellite) over a coaxial connection check connections and tune the TV to CH 3 or CH 4 and check for picture. There may be a switch on the back of the box indicating CH 3 or CH 4.
Verify the batteries in the remote control
are good.
Verify you have selected the right input
for Cable/Satellite, antenna, DVD, VCR or Game Console.
Verify the cable/satellite box is plugged
in and getting power
Verify you are getting cable/satellite in
other parts of the house
Verify the VCR is plugged-in,getting power,
and turned on.
Verify that all wires are connected to
proper place
Scroll through input screen to verify you
are watching the correct inputs
Look at the FAQ on the manufacture's
website or user manual
The Basics
Before we
explore more complex tv troubleshooting techniques, we need to examine the
basics. First, we need to verify the TV is securely plugged into a power
outlet. Don't laugh, but failure to plug-in the TV is the number one reason
reported why electronics do not work. Second, you need to verify the remote has
fresh batteries. This can easily be overlooked. The remote can be working one
minute and not working the next, so replace the batteries Finally, verify
that all cables and connections are correctly and securely attached.
check the incoming signal connections, if a cable is loose or damaged end on the coax can do this either at the set or the box if one is used, if you have another set connect it where this one is at, either the set, a box or a cable unless the provider is having a problem in your area..
worst case would be the tuner in the TV has failed but that is rare, there are some ways in that case to get around the problem.
Hello,
With the cable securely connected to your new TV, go into the Menu setup features and tell the set to AutoProgram all cable channels. It will then search for every signal. This will take a few minutes but give it some time to scan,
If it cannot find anything then you do not have a proper cable or antenna signal.
Cheers
Try using the video inputs
What to do if you have an all snowy picture (blue screen or the TV displays unusable signal-no signal or no sync)
1 – If you are using a digital cable box or satellite receiver (make sure it’s on) and be sure your TV is set for either CH3 or CH4 (which ever you usually view it on). If you usually view it through video inputs (video1 or 2 etc.) make sure the appropriate input is selected.
If you still don’t get a signal see if you get picture using the DVD or VCR (if available) if you do than plug the satellite or Dig. Box temporarily into the place of the DVD (unplug DVD) you may have to use some A/V cables (RCA yel./red/wht like the ones on the DVD) to hook to the tv from the sat./dig. box. If you get a signal then the sat./dig box is ok. If not the Sat./dig box is not sending a signal and is either defective or needs to be rebooted (unplug wait 5 min try again).
2 – If you are using standard cable or antenna (source) if possible check that the source is good by connecting to another TV. Otherwise try running the source into a VCR and then out to the TV using video inputs (RCA yel./red/wht like the ones on the DVD) and then selecting the appropriate input. Try seeing if the VCR plays using standard CH3 (or CH4)
If the VCR plays on video input but not when connected to CH3 (CH4) then the tuner of the TV may be defective – see if you can use the VCR to change channel using the VCR remote. Be sure to vote/rate me if this helped Thanks!
Usually a snowy picture means that you have a bad ground connection. You should see that some channels are beter than others. Verify that the cable connection is good. Try a different cable if you can. If that has no effect, than we need to start looking at the tuner itself. If you can change channels but just have a poor picture, chances are that a resolder of the tuner section will resolve the problem.
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.
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.
