I think the 'front end fet' or channel fet has failed
this amplifies the incomming antenna signal
however is the center pin of the antenna plug on the tv loose
inside the tv is a metal box this is attached too
it changed the UHF signals to a lower frequency range called an IF
the UHF signals are normaly have a path like this
antenna>>safety >>>amp>>mixeramp>>output to DTV decoder etc

the amp bit or connection to the tv is wrong
as its working quite well and gets like 2 channels

look inside the socket on the tv and examine it carefully for any bits of wire
or as i say loose connections
may just need to be soldered inside the can to reconnect the center pin

it will still give like 2 3 channels as the gap caused by the bad solder joint
will still allow some RF accross
so... its either a gubbed UHF RF amp or a broken connection or a short ... so...

Why will my new tv not pick up any channels when using the auto channel search


It depends on if you have cable or are using an antenna. If you have cable, make sure you have the cable that runs in between them hooked up to the correct spots. If you're using an antenna, you might need to get a TV converter box. A couple of years ago, they stopped making regular TV channels and switched to only digital channels. Most older TVs don't work with digital channels, so you need a box that will convert the picture. You can get one at any place that sells TVs (walmart, amazon, etc)

I have a VIZIO E552VL TV hooked up to an Over the Air Antenna and want to MANUALY put in channels NOT AUTO SCAN


Not sure if your TV is digital or analog, but I think an analog TV does not have the ability to perform auto scan, so you may be able to manually input the channels. As a kid, my dad installed a rotary antenna, and as it rotated and TV pictures displayed on the screen, dad noted the specific spot on the rotary unit; and every time we turned the set on, we just pointed the arrow on the dial on the unit to where dad noted what the channel number was on the unit, and the antenna turned toward that direction, and the pictured appeared on the screen.

I am moving tomorrow and won't be able to afford cable or satellite for awhile. I have a newer model Sanyo tv. Will I need a converter box or can I hook an antenna directly into the tv to pick u


If your TV has the screw-on coaxial cable connection on the back, then you will not need a converter box. You can attach an internal or external antenna and have your TV scan for digital channels. The converter boxes are mostly for old CRT TVs with analog tuners or newer home theater "monitor" TVs which are being produced without built in tuners.

How do I get local tv channels on my tv without cable hook up if I have a built in converter


You need to find out what antenna you need and the direction it should point to get your local stations. Antennas are given a color rating based on how far away the transmitter is that can still provide a good signal. The actual results may vary due to trees, hills and buildings.

antennaweb.org and tvfool.com are good starting points; just type in your address. Antennaweb.org is very conservative in the available channel list even with assuming you have an external antenna. Get the appropriate antenna and point it in the best direction for the channels you want. Connect it to the TV (coax) and set the TV to scan for OTA channels. (Usually the source or input must be TV and then enter the menu to set the TV to OTA signal and scan for all channels.) You do need an ATSC tuner these days.

If you are splitting the antenna signal to several TVs, you probably should add an amplifier to the setup.

I hope this helps.

I have the box installed and on. Now what do I do to get the local stations on my TV


What box - satellite/cable/digital-to-analog converter? This tv has a digital (ATSC) tuner built in. So if you are looking for OTA channels, use antennaweb.org or tvfool.com to find out what direction to point your antenna and what antenna you need. Then connect the antenna's coax cable to your TV. Antennaweb is very conservative and assumes an outdoor antenna. tvfool.com will list several more channels and the different antennas that are needed for various distances between your location and the station transmitters.

If you are sharing one antenna between several tvs or tv and other devices, you may need an amplifier in addition to the splitter. (Unfortunately, these can get damaged by surges as well. I've lost certain channels after a lightning strike turned the amp into a filter for one part of the RF signal spectrum.)

Once you have the antenna connected and pointing in the direction of the desired station, you will need to scan for channels. If this is the first time the tv is set up, you will be prompted for menu language, the input type and then asked if you want the TV to auto-scan for channels. Otherwise, hit Menu, use the left and right arrows to get to the Channels menu option and press the + button in the center of the arrow keys. Next use the up and down arrows to set the incoming signal (if needed) - the item is labeled Cable and is a Yes/No (again press + to select item and to enter the change). Continue down to the Auto-program and let that run. You can add/remove channels from the resulting listing with the Channel Skip/Add option just below Auto-program.

I hope this helps.

GE Model 20GT360 TV and digital antenna problem


Are you connected to a digtal converter or just a digital antenna? If only to an antenna then yes you will most likely pick up one or two low power UHF stations that are still able to broadcast in analog.

I can't scan DTV channels on my vizio 52''


do you have antenna or cable? if you have antena hook directly to the coax, go to menu, TV, tuner and pick antenna and scan. If you have cable hook directly to your coax repeat the previous step but pick cable instead of antenna. Notice if you have a cable box, you will not need to scan for channel since it will be on channel 3, 4 or any other input you may use.

Dont know how to get cable channels , i just get local channels.


Hello.

It sounds like you need to change a setting before running the auto or channel scan. On the same menu screen that has the option for running the channel scan, you should see a setting that has next to it the word "AIR" or "ANTENNA". If this isn't changed to "CABLE" or "CATV" then the TV will only scan for a limited number of channels because it assumes you have an antenna hooked up to it instead of a cable line. This is the same for all TVs. Anytime someone runs a channel scan on ANY TV and they only pick up a limited number of channels, they need to change the setting I've described. And remember, it will be on the same menu screen that you go to in order to run the channel scan.

I hope I've provided you useful assistance and that this information allows you to make an informed decision as to how to proceed from here.

Please let me know if I can be of further assistance.

P.S. On some TVs, autoscan is called autoprogram.
