Problem is direct "ingress" of the terrestrial signal from the TV station (off-air) on to the cable along with the signal from the cable company. Typically caused by faulty/bad/cheap connectors and cables. If you are certain that the signal is clean from the cable company, then the best solution is to replace the cable in your home with good quad shielded cable, with good tight connections made. You could start by checking all "F" connectors top see that they are snug. An amp may increase the signal enough to overcome the ingress and help a bit, but it usually just amplifys the same signal.

SimplifydigitalJul 11, 2014 - This handy guide will help you fix simple digital TV reception issues with Freeview, satellite and cable TV set top boxes. ... If you're suffering from poor digital TV signal, it may be possible to fix reception issues quickly, at home. ... We're here to run you through how to fix TV ...
Try the resetting the TV. To do this unplug the power chord from power socket, and wait for atleast 45 minute. TV will reset itself. The try to get signals.
If your TV receive poor quality telivision signals, captioning may contain errors, or there might be no captioning at all. Some possible reasons for poor quality are automobile ignition noise, electic motor noise, weak signal reception or multiplex signal reception like ghosts etc.
If reset also didn't help you, the tuner inside your TV is defective, or weak. It should be replaced with same type and number. OK.
The pixellation on cable channels usually indicating poor/weak cable signal. You may want to have the cable signal strength check out by the cable company, check your cable connection at the entrance of the house to make sure they are clean and tight, try connect and disconnecting them. You are not the cable company cable box are you? My had to be replaced twice by Comcast, they were running very hot.
1. You could have the cable plugged into the wrong port.
2. How old is the TV? If it isn't brand new, It's probably analog, and won't work if you're trying to pick up an antenna signal. For that, you'd have to buy a digital converter.
3. Do you have a cable box? If so, your TV should be set to one of the "Video" channels, not the numbered ones. Try hitting "TV/Video" on your remote until you see a picture. Make sure your cable box is on.
4. Everything else would pretty much boil down to poor signal, or broken equipment. Call your cable company if you have cable to determine if it's a signal issue.
I assume you have cable. The cable HD and digital channels are usually sent in Quadrature Amplitude Modulation (QAM). The cable companies are required to send local channels in the clear but not so for any others. Regular (basic) channels may be clear or scrambled. USA many not be but HBO will be.
So you have 1 of 2 problems: (1) your TV does not do QAM or (2) they have scrambled the channels you want to see. Questions: (1) Have tried direct Over-the-Air (OTA, ATSC) reception for your locals? (2) Can you see the HD local channels on cable? (3) Are you paying for an HD box from the cable company to have the channels decoded? If in doubt contact the cable company.
Current Samsung TVs do do QAM and OTA HD. Alternatives are Dish or Direct to get satellite with an HD receiver using HDMI or 5-cable RCA. Costs are comparable but OTA wins, hands down.
The channel guide is a service just like closed caption. Rumer has it that it's not going to be around for much longer. The only fix is to unplug set ..wait awhile till memory loss occurs...plug back up and do a setup. Nothing in the TV will cause partial guide. Weak signal could and cause fuzzy picture too. Complain to cable company. But brightness problem is something else.
It sounds like a problem with the tuner in the TV set. Hook up a VCR through the video inputs and hook the cable through the VCR and if the picture is still snowy, the problem is the cable. If the picture is clear, the problem is the tuner in the TV set. If you wanted, you could simply leave the VCR attached to the TV set and change cable channels through the VCR, or have the TV serviced. Good Luck
no they are not related. ur tv seems to have a defective tuner(inspect also for possible cold solder inside the tuner). remote control can be clean using a cotton swab with a little isoprophyl on it. clean the contact on the pcb.
