Are you sure your cable coax source is broadcasting any unencrypted digital channels, and is the signal strenth relatively good? In the Channel Scan, you need to also specify the source/input type as digital, and be sure to use the coax connector marked DIGITAL Cable (or similar). Begin the autoscan--it will take a while as the TV tries to tune any/all digital signals--most of which, if you're cable provider is like 90% out there (interested in profits), this might take 15-20 minutes, and will likely end up in lotsa black non-broadcasting detections (placeholders for on demand content), but hopefully, you'll find a 1/2 dozen or so 'clear' unencrypted. If you know the channel of a KNOWN digital local, tune to it, even if the picture is not initially visible. The lock-on takes a few seconds and if a signal is weak, it may take a long while if it can lock on at all. Usually, you'll find your local PBS stations on unencrypted channels from your cable provider, along with major network tv stations (NBC,ABC,FOX,CBS), but it all depends on what the cable provider allows. Don't expect them to tell you what exactly is free either! Underground webs will list your provider, Google to find out what to expect, and don't expect what you find to be all accurate. If you're in a decent reception area, and have any sort of an antenna, you'd likely pick up some of the OTA HD broadcasts, maybe even with just a coathanger :), just to verify that your QAM/OTA tuner is functioning.

I hooked up my tv and I only get sound on the dvd not when I am watching just the tv


This makes me believe you have either a bad connection with your coaxial cable to the tuner or the tuner may need serviced.

Connected the coaxial cable to the tv but got no channels. the tv turns on but all I have is snow


Some possible things to check:

1. Are you trying to receive off-the-air broadcasting? If so, you'll need a digital converter box. This set doesn't have a digital tuner, so there won't be any channels for it to receive without the converter.

2. Are you connecting a cable from a cable converter box, satellite receiver or FiOS set-top box? Your TV will need to be set to channel 3 or 4 to see the signal from the device.

3. Make sure the center wire in the plug on the end of the cable isn't bent over, and that it extends far enough (about 1/8 to 1/4-inch) to make a good connection.

4. Do you know for sure that the cable you are connecting is working? Is there actually a signal on the cable? It may be disconnected somewhere else (at a splitter, for instance) or there may not be any signal source.

5. Have you tried another TV to test the cable? If the cable works with another set, the tuner or antenna connector on the snowy set may be bad. If the cable connector is tightened too much when hooking it to the TV, the connector may be damaged and this can cause the snow.

Start by checking with a known good TV. If that one is snowy, you can check the other possibilities. If it works, you'll know the problem is in your set and can decide what to do (repair or replace).

Hope this helps! Thanks for using Fixya.

N 0 tunneing signal


Most of these TV's are equipped with a on board digital tuner and most people think well heck I'll just hook it up to the cable outlet what the hay. But little do they know there cable company wants you to have there box fer you tuner to work. Make sense?

1. Call the cable company and ask for digital signals to be sent without a box (requires a cable card).

2. If your not using a cable company network and trying a antenna your going to need a Digital antenna's and you also going to need line of sight (no not like sat dishes) I mean pointed at the Broadcast antenna.
if your in a rural area umm your going to need a outside antenna.

I feel what you got here is:

1. ether a OTA over the air antenna and your two far away.
2. or your trying to connect to a cable network that is broadcasting locked digital signals.

Ether the case you must investigate but 9 times out of ten that is what it is.

Or

1. you tuner is bad(not hardly)
2. the connection is bad.

Ether case here you need to investigate, please do rate my solutions and click the accept button for my efforts.

Coaxial output broken


If the connector end is not damaged and the tuner circuit board is not broken, you can solder this back onto tuner, and solder the end back on the circuit board. You should take the tuner out to do this proceedure. A TV shop usually charges $50.00 to do this.

How do we adjust our tv


You didn't mention anything about a cable box, VCR, etc. which might be connected. A snowy pic. means simply, inadequate signal is reaching the tuner, or the TV tuner itself is bad. If the first is so... check your cabling. If you have a VCR or DVD player hooked in between the cable box or outside antenna (whichever is the case), VCR (RF or ant.) out should go to the TV, VCR antenna (RF or ant.) input to the cable box. Also check the cable wire itself. If you look at the end of the cable, you should see a relatively thin center wire. This center conductor is what carries the signal. If it is missing, bent over, or too short to make contact with whatever it is connected to, you will have a very snowy pic. If you have a spare TV, connect it in place of your "new" TV, to narrow down the problem. Lastly, if all is well with hookup, cabling, etc. the TV might have a problem. Sometimes the tuner has a component defect, or the coaxial connector can be broken.

Connecting VCR/DVD combo to TV


If that is the only input that the tv has it's still usable. Just plug the Cable TV or antenna cable into the DVD/VCR coaxial input labeled "in" (instead of the TV's) and hook one from the DVD/VCR's "out" to the "in" on the tv. Turn the TV to channel 3 or 4 (depends on DVD/VCR settings) and use the built in TV tuner on the DVD/VCR to change channels.

Can't get cable channels, only goes up to ch. 13


First check and see if you are on Cable or Ant. It sounds like you are on ant. Change it to cable. If you are on cable then it's you tuner, you need to replace it.
