Snowy picture on certain channels and only sometimes
Recently the Comcast cable had a problem with service and the cable kept going on and off ever since then certain channels have been really snowy/fuzzy and other channels somewhat fuzzy, could it be a problem with the TV now or could it be the actual cable , it used to never be snowy/fuzzy, is there any settings we can check on the tv

Try to go under the setting with the cable box and see if it has a switch to choose HD channels first. What cable companie do you have?? It could be possible that you will need to call to get HD service.
Sometimes the HD channels tend to be be late in the programming guide(I have comcast of Virginia and most channels are 700+)

Depending on your cable provider, some of the HD channels may be present. If so, these are ususally located in the upper channel numbers. It sounds like you are receiving some of the HD lineup. A cable box will probably allow you to view more HD channels including the premium HD channels if you subscribe to them.
You should not be noticing a delay with the HD channels only. If this is what you are experiencing without a cable box, then it would be an issue with the HD tuner built into your TV set. LG customer service can let you know if there are any software updates available for yourmodel that can resolve this. Additionally, if you are getting your sound from an Home Theater system then you will notice an echo if using the TV's built in speakers at the same time. This is sometimes mistaken as an audio delay. If you are using a home theater system, be sure to disable the speakers that are built into your system.
In all likelyhood, you have a bad ground somewhere in the cable. Try other channels through the VCR. If the ground is the problem, there will be a cluster of channels that are snowy with the rest being clear. Check the cable itself and all of the connectors along it.
If the cable and connectors are good, the tuner or power supply of the VCR could be faulty and cause this as well.
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.
If you are on cable, first run the cable wire from the wall directly to the TV, eliminating any cable box and/or VCR. If channel 2 is snowy but the rest (especially 3-6) are clear, it is most certainly a cable problem and not a TV problem. The TV uses the exact same circuits for channel 2 to 6 (VHF-LOW) so if the tuner was bad and 2 was snowy, 3, 4, 5 and 6 would be snowy too. Bring a second TV into that room, disconnect the cable wire from the RCA and connect it to the second TV. Is channel 2 on the second TV as snowy as it was on the RCA?
You could have a bad spitter or a fitting could have come loose.First thing to do is to take another TV set right next to the bad TV set and plug in the cable to the other TV set to see if the same issue happens. If it does there is a cable issue. If it does not have a snowy picture, then you should call the store where you purchaced the set for exchange or service. Good Luck
