When tv is turned on with cable channels picture is snowy. when dvd or vhs tape played through tv the picture is snowy


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.

No digital picture on digital TV


Are you getting a snowy picture, If so, you`re still on analogue. If you are on a digital channel with say no signal, you should get a blank screen with either a message saying no signal or a dot on the screen. Ian

Their is no more you can do.

Bought a proscanlcd hdtv 32lb30Q unable to get cable signal


Hi and welcome to FixYa,

Initially, pls confirm if below is how it is wired using a coaxial cable and not 3cable RCA to RCA:
  • Charter Digital Cable > DVD/VCR > TV
If yes and your concern is snowy or no signal on the TV screen, might it be that you have to power OFF the DVD/VCR when selecting channels on the TV itself (including when channel setup is being done).

Alternately, you can tune the TV to channel 3 and let the DVD/VCR do the channel selections.

Pls post back results. Good luck and thank you for using FixYa.

What is your TV input connection? Are you using Antenna? Cable? Dish?

The Unusable Signal sounds like the TV is not getting a signal. Does your TV have a built in HD Tuner?

If you are using Antenna you might want to try setting up the connections and it should search for quality channels that you get good signal strength. If you are on channel 2 and there is no over the air channel 2 it may say "unusable signal".

Snowy picture


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.

Keep us posted.

Snowy picture


Hi,

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.

Ther is a test you could do is you had the proper equipment, and that would be to inject a know good RF signal into the tunner F connector and chech tha point where the RF/IF is converted to audio and video, to determine if the proble is a bad tuner or not. The equipment is a VA62A Universal Video Analyzer. Its a great piece of equipment for this type of work. another thing you can do is get an RF Modulator from Radio shack and input a video and audio signal in to it and set it to channel 3 and connect the F connector to the TVs F connector. The set the TV to channel 3 you should see the picture and hear sound in channel 3. The VA62A is best because you can set it to emulate all of your channels from 1-87 standard TV and Cable TV. In any event a test needs to be run to see if the tunner is at fault.
