Toshiba 50h12-reception problem with ant 1 & 2

I have cable tv and it is a coaxil cable, when i hook it up to the back of the tv set in either antenna 1 or antenna 2 the picture looks like it is scrambled, i have 5 other inputs on the tv set but all are rca type. the cable is fine because it will work on other tvs. there must be a malfunction in the 2 inputs that are coaxil. i cant find a converter that will convert coaxil cable into rca plugs. do you suppose if i took the back off i could figure out why the 2 inputs are bad, please help.

The tv has a built in decoder. if its scrambled it may be on the wrong setting. try resetting tv to factory settings and see if it sorts its self out. if not it may need the av board changing as it has a fault with the decoder chip.

SOURCE: basic cable scrambled on ANT input but not PIP

it sounds like you have the common problem with these models. The poblem has occured so offten that toshiba issued a service bulliteen about it. There is a problem with a cuircit board called the Hypermodule its a signal processing board/ the ideal situation would be replaced this board but it has happen so much it may be difficult to find this ooard so this board can be repaird. The secound problem is to fix this board 11 very very small parts called capacitors need to be replaced. i have also replace these and only someone advance in solder should attempt it very small. twezers and magnifer. You can hire someone but it very labor intensive. Our shop charges 300 just in labor It can be fixed but I would adviise its just no worth it

I have a toshiba 42HL196 tv and i am trying to connect it to an external antenna. I cant find a channel scan option in the setup menu. The menu on my tv is not the same as the toshiba video.

First check the current source. Press the Input button on the TV (second from the left) or on the remote (below 9) until the correct Antenna input (Ant 1) is selected. Make sure that the antenna is connected to Ant 1 (the RF connection closest to the back HDMI ports). You only use Ant 2 if you have a coaxial (RF) cable connection. Then press Menu and then try the Setup menu again. You should be able to access the Installation menu and Terrestrial sub-menu now. Change the Input Configuration for Ant 1 to Antenna before attempting to Program Channels.

If this doesn't work, try resetting the TV to the factory settings. You'll have to access the Menu, go to the Installation sub-menu and then select the System Status and then System Information. Select Factory Defaults and enter the PIN. See the manual for the default PIN if you haven't changed it. Then confirm the reset. The manual is available from the product support page: http://support.toshiba.com/support/modelHome?freeText=2841536 . The direct link to the manual is http://cdgenp01.csd.toshiba.com/content/support/manuals/userguides/su2846615/42hl196_om_e.pdf . See page 29 for the PIN. Then try accessing the Terrestrial menu and scanning for channels.

I hope this helps.

I moved and cant figure out how to hook my 4030 channel master antenna up again. I have a converter box and hd toshiba tv

INSTALLATION

Channel Master by PCT indoor antennas are designed to provide optimum reception of

UHF / VHF and FM signals. These antennas have 75 ohm outputs, which allow simple,

hassle-free connections to today's newer TV sets that have 75 ohm F type connector

inputs.

Simply attach one end of the supplied 6' cable with F connectors to the output of the

antenna (Fig.1). Attach the other end of the cable to the input of the TV set or VCR

(Fig. 2). Some adjustment of the antenna might be necessary for optimum viewing.

Model CM-4030 includes a built-in amplifier and separate power supply.

1. Follow the same steps as above for antenna to TV / VCR hookup. Note : Model

CM-4030 also allows for two set / VCR hookups with its unique dual output feature.

2. Insert the power injector into the back of the antenna (Fig. 3). Plug in the power
transformer to the closest electrical outlet (Fig. 4).


Google 4030 Channel Master Instruction Sheet for the PDF File with the diagram.

On the vizio 55' hdtv led lcd my mother just bought yesterday . I need to hook up TV cable which is a coaxial cable and the roof top Antenna which is also a coaxial cable but on back of the set ,there is...

Hello

On alot of cable boxes there is also an "ANT IN" that you can bring your rooftop antenna in to. When you turn the cable box off, it passes the ANT signal to the tv.

I hope this helps you out

How do we make my TV capable of receiving regular local channels without cable or satellite hook-up?

You would have to hook up an external TV antenna on the UHF/VHF band and run a coaxial cable from the antenna to the TV and plug in the "Belling-Lee" connector into the "Antenna" socket at rear of unit.. This should enable reception via "Normal TV"

Prong on RCA antenna cable too large for spot on Toshiba vcr/dvd

Hi, You need to look on the cable itself to see if it is an RG58 or RG59 or RG6 or RG9. On an RG6 cable the center conductor is larger than on an RG58, The RG6 cable is used for incoming cable, satellite ect. An outside antenna is not usually equipped with an RG6 unless it is of the new HD variety, which is meant to go to one of the newer tvs. You can remedy the problem a couple of ways, use the ant out on the tv if you have one or use an adapter that fits 2 coax cables together and use a RG 58 jumper from the adapter to the vcr. Good Luck!

Want to use DTV converter with my Toshiba 32AF42

If you're not on cable or satellite, you will need an antenna to get off-the-air reception. This TV does not have a DTV tuner, so you will also need the converter box. Depending on how far you are from the broadcasters' transmitters, you might be able to get away with an indoor antenna. Or you might find that you get few channels with the inside antenna and then you'll need something outdoors. There are a number of styles to choose from.

The antenna hooks to the converter box, and the converter box then goes to the TV. It can be hooked to the TV's "ANTENNA" connector. This should be covered in the set's manual where it shows you how to connect a regular antenna. With the box, your TV will always stay on channel 3 or 4 (depends on how you set up the box) and you'll change channels on the converter.

You can also connect the converter to the TV with audio and video cables like you would a DVD player. Most of the "coupon-eligible" converter boxes include direct video and audio output jacks. This gives you better picture and sound quality than by hooking it to the TV's antenna input.

Hooking up a converter box is like going back in time to when cable TV was new and you had to get a converter box from your cable company. Same way of hooking it up. Hope this helps!

RCA DRC8030N

That sounds about right if you have cable instead of an antenna cable. If it can't tune anything but 5 channels in, that's all it claims; set it to CABLE IN instead and try that so the tuner can get along with your cable box. If you really do have an antenna hooked up, get it away from whatever's reflecting signal and screwing up reception.
