SOURCE: the cable coax male connection is disconnected from the television

The coax connector you describe is called the F connector and the silver box it is attached to is called the tuner. The original F connector or a replacement F connector can be soldered back into the tuner, but the metal frame of the tuner must be straightened out and the center pin must be delicately reattached too. This is quite an easy job but requires some labor, assuming that nothing was jammed into the tuner when the F connector was out and the coils behind the F connector have not been disturbed. I usually charge about $40 to reattach F connectors but if I have to replace the tuner I charge about $50 because it is a lot less labor to replace the tuner and they can be purchased for about $25.

SOURCE: Connection to Dish service

Your t.v is having only RFin , and if you connecting dish receiver , normaly their are two o/p for receiver one is RF and two is for audio out and video out. if your connecting direct RFout to t.v RF in then you have to tune the t.v in all bands. if your receiver do not having RFout facility, then you have to connect AV out to converter and then RFin of t.v. if you having a vcr, then connect AVout of dish receiver to vcr AVin and then vcr RFout to t.v again tune the t.v and pwer on the vcr.

SOURCE: digital to analog converter box hookup

You will have to go to Radio Shack or Wall Mart, maybe Home Depot and get a matching transformer. That will have spade terminals on one end to connect to your tv and a round (75ohm male thread) to hook to your converter box.

I need to know why the no signal is coming on and icant tune tv

Okay if you have no signal signal first thing to do is make sure you have that either HDMI or the coax cable connected if you do have them connected and you're using the coax cable and air antenna need to switch the TV to air in the settings menu if you have a cable connector that uses coax you need to set up your cable that is most likely why

What causes pixelation only on digital 9 TV and there subsidiaries

Pixellation is a weak and noisy signal coming in. Digital HD needs a good signal at the antenna socket on the back of the TV. You need to have good quality quad shield coax cable down from the antenna, and preferably crimped F-connectors at each plug and socket. You may even need a new digital antenna if you are making do with an older analogue one.

Your other stations will also improve.

I have reprogramed a LG tv and it keeps says no signal after receiving 5 to 11 stations

Sounds like you need a better antenna or an amplifier for you antenna. But check first you antenna coax connection to make sure the electrical connections are tight. Also check your coax for breaks in continuity. You can do this with an Ohm meter. You should have near zero resistance center to center of the coax and same for the out shield. More likely the problem is not your coax but a weak signal from over the air. Also check to see that your antenna selector on your TV menu is not set to Cable but rather Air assuming your are wanting to pick up free over the air signals and not cable.

Picture breaks down on some stations saying no signal or signal weak.

2 possible solutions, 1. If you have any type of dish network, go into the service part of the menu and check the signal strength usually a signal on any of the transponders less than 70 will cause this on some channels due to thier own signal. You can have either a tech come out,( sometimes for free, or you can adjust the dish very i reat very small increments so as not to diviate from the correct izmuth setting originally aimed at. to do this, you can do it yourself by selecting signal strentgh meters on the menu and raising the volume so you can hear the repeated blips while adjusting the dish. The sound your looking for is like the old Pong game on atari. The faster the blips, the stronger the signal. Slower blips mean your aligning the dish in the wrong direction.

2. Check your coax cables. If their old, they may not support the bandwidth being sent through it. Check at connections, ( All of Them) they wear with age. Is the cable itself at the connection protruding enough to enter the receiving female part. When you unscrew a coax at the connection, it should have about 1/8" to 1/4" copper cable past the connector and in clean, good, straight condition. make sure they are tight, and good luck

Most of the channels breaking up despite auto retuning

could be one of a few things,
low signal strength, aerial out of line with transmitter.
bad coax connections losing signal strength.
coax broken inside, or old and not low loss.
Get the aerial checked for direction, half a degree out of line over a few miles and you will lose a lot of signal strength, as will old coax (aerial cable) and if you are using an unshielded coax you could be losing signal strength through the cable itself. Replace the connecters and try to use a straight run of cable instead of having joins in it as these joins, even if using connecters, will cause a weak signal. If yiu are running more than one tv off your aerial, invest in a booster.

Remote Antenna

I suggest LMR-400 cable, but generally most any coax cable will do. As far as your connectors, I suggest visiting RadioShack or The Source for these, remove your existing antenna and bring it with you to determine what N-Connectors you will need.
