Only the older Analog type televisions get snow from lack of signal. The modern Digital TV gets pixilated. like missing pieces.
And on re-reading the title of your question, it does say CRT...... As in Cathode Ray Tube. (I thought they were all gone now, all around the world) Anyhow.... has your country switched off it's analog tv transmissions. This would give you snow. Because there is no Transmission. Seems unlikely they would stop transmission in the middle of what your watching.
So
Do you have a Digital Set Top Box feeding the TV? This would pick up Digital TV transmissions and convert them to your old CRT TV Screen. Knowing this should help you diagnose the problem.
Check the antenna input to your digital box and connections from the STB to your TV. They probably use a Yellow video cable and a Red & White (Sound Left & Right). You didn't mention if sound was still there?
Perhaps someone has pressed the remote control and the TV has jumped to one of the Antenna Channel inputs rather than the Video input (Yellow Video input)?
Might be that Simple.....
Good Luck
U follow the tv owner manual instuctions for scanning for the DTV free over the air broadcasting by the tv stations signal yet.Do that first,still have a message weak or no signals.Buy a newly design Digital antenna or have a roof antenna already hook it up to the tv,follow the owner manual rescan it again will have all DTV free over the air broadcasting tv channels.
Basically you are not going to get good quality TV reception on an internal antenna unless you live very close to the transmitter aerial with no significant metal structures (including buildings) in the way. You may get a slight improvement by placing the antenna near a window and away from any large pieces of metal or other electrical devices, especially any with a large magnetic field (anything with a motor in it). You may improve the signal / noise ratio by making sure that you have good quality, foil screened (satelite grade) cable between your antenna and TV set.
If the building has a (shared) roof top antenna you might get a better signal, which can be boosted using an in-line signal amplifier from that - but only if it is pointed at the right transmitter. However, as you will be installing the amplifier close to your set it will (just like the amplified antenna you are using) also amplify any electrical interference picked up by the cable as it passes down through the building - including from cars outside.
However your best bet is going to be cable or satelite TV
digital air signals are weak and fussy. They are easily lost by having trees or large buildings in the way too.
The best thing to do is install a long range roof top antenna and re program the set. Be sure to aim the antenna correctly. if you cannot use a roof top antenna you can try the indoor digital antennas,but less likely to work consistently
If you're in the US, you will no longer get antenna signals because the US has recently switched to digital. The TV you have does not have a digital tuner and you'll need to purchase a digital converter box that converts a band of analog signal to digital.
If previously some of your channels were freezing or pixilating etc. this indicates a problem with your signal hence the reason why some of your channels have returned, this depends on the strenght of the sincoming signal. Check your antenna connection & cable if that doesn't help, then check your antenna has not moved off alignment & if so re-position it.
Ok first I can save you some money. Take your "HDTV" antenna back. There is nothing different about the antennas needed receive analog and digital signals. If you got reception without your converter box, use the same antenna with your converter box.
Next let's see if there is a problem with the box. Hook up a television with the antenna. How many stations do you get? Now hook up the same television & antenna, but this time put the converter box between the antenna & the TV. Do not turn on the box. Now how many stations do you get? If the number is different, the box is not allowing the antenna signal to pass through. That is bad. You want your signal to pass through the box so you can still pick up stations that don't broadcast digitally. Some areas of the country will not be covered by digital stations from all major broadcasters when the changeover happens in Feb.
My suspicion is either you did not have the antenna hooked up to the converter box when you searched for channels OR you are in an area that is not yet broadcasting digitally.
I hope this helps you solve your problem. Thank you for using FixYa and feel free to add more questions here by using comments.
If you are using an antenna the signal is too weak to broadcast the tv station completely, it is asking you to move the antenna to get better reception, if you are using rabbit ears you can move the antenna pretty easy, if you are using an antenna that is on the roof it's not as easy, if this is the case you can go to an electronics store or Radio Shack and get an antenna booster it should help you
Hey adam, check that antenna wire! It's probably pulling out at the antenna/magnet end.
Adam, I checked that and sure enough, it was pulling out. So I put on a new antenna and problem solved!
Thanks Adam!
