Brought a GE model 27gt722 tv...can not pick up all channels on cable. Usually once you hook up cable wire to tv cable is automatically on least that is how it was on old tv

Depending on the cable company, some like Comcast have gone mostly digital meaning when you connect the TV directly to cable without a cabe box you will only get around 35 channels. The only way to get around that is to get a cable box. If you have Comcast service already they offer what they call a DTV cable adaptor which will allow you to get most cable channels. These DTV adaptors in most areas are free for the first two per household. I hope that helps : )

Hi, I bought this tv at thrift shop last week. No instruction manual available. I got cable from Time Warner. Got the cable signal and got tv working. 3 days later no cable. I don't know how to...

If using a cable box then you want to set the TV to channel 3 or 4 as the cable box will output to one of those. If no cable box then its possible the TV's tuner is bad or your cable company only transmits in digital form requiring a cable box since this TV only has an analog tuner

Rca model f36649 s-video hookup to laptop computer When I hookup s--video cable to tv & HP Pavillion dv9000. I get nothing on tv? I have tried putting tv on channel 3.

Depending on how many hook ups you have on your tv it may have a factory designated channel. Example: Video 1, Game, etc. I know my TV has several different video channels. It's more a matter of trial and error until you find the vidoe channel for your oulet. Input channels are usually found before channel 1. Or look on your remote and see if it has a button to switch the channel to your input channel. Good Luck.

Cannot get the cable to show on this tv

If the TV is connected to a cable box using 1 solid cable (RF ANT) your needs to be on either channel 3 or 4.
If the TV is connected to a cable box using 2 or 3 RCA cables, your TV needs to be on AV 1, 2 or 3.
If the TV is connected directly to the cable, go to MENU set the TV to cable and program channels.

Good luck

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. -Ken

Cannot connect zenith vcr to zenith tv thru cable box

Hello mcgillicu390,

From your VCR you should have an (RF OUT) and an (RF IN) Connector (these also might be marked as ANT IN and ANT OUT, or CABLE IN and CABLE OUT).

The same goes for your TV (RF IN), (ANT IN) or (CABLE IN).

Now, take your Coaxial Cable (Cable with screw on or Push on connector with a wire in the center of it) and connect it to the TV (RF IN), take the other end of the same cable and connect it to the VCR (RF OUT).

Then connect your cable TV set top box or antenna to the (RF IN) of the VCR.

If you are using a cable box set your VCR and TV to Channel 3 or 4 (depending on your area)

If you are just using the VCR and an antenna set your TV to channel 3 or (depending on your area).

That should do it for coaxial connectivity.

If you are using the composite video and Audio cables to connect to your TV here are the directions for that.

Looking at the back of your TV you will see Three RCA type connectors colored as Yellow, White, and Red. Yellow is Video, White is your Left Audio, and Red is your Right Audio. They should be marked as (Video IN), (R Audio IN), and (L Audio IN). *note these markings may not be exactly like what is written, however the indicators should be close to what you are seeing.

Now look at your VCR, you may see a lot of RCA Connectors (up to 6 of these connectors) don't worry, you are only looking for the ones that say (Video OUT) (R Audio OUT), and (L Audio OUT).

Once you find the connectors on both pieces of equipment, take the Yellow, Red, and White tipped cables and plug the in their respective jacks Yellow tipped cable connects VCR (Video OUT) to TV(Video IN). Red tipped cable connects VCR (R Audio OUT) to TV (R Audio IN), and finally White tipped cable connects VCR (L Audio OUT) to TV (L Audio IN),

Once the cables are connected you will be able to use the composite selection on your remote to view the images from your VCR, the VCR in this case will be acting as the tuner for your TV with out you having to set the TV to channel 3 or 4, you will just have to use the AUX or whatever setting on you remote that allows the composite video to display.

I hope this helps,

Thank you,

Doesn't get all cable channels

With the menu set to cable signals, the autoprogram should catch all of the cable channels. The Cable Channel option allows you to use either channel 3 or 4 as the "cable" channel. This is when you have an external box that you use to tune in cable rather than the TV directly. The easiest way here is to autoprogram the TV while playing a VCR tape. That will insure that channel 3 is included.

Does the autoprogram fail?

Channels disappear

Because your problem appears after 1 hour... suggests me that your TV's tuner unit or cable box is at fault.

After the unit generates heat, the components (capacitors) in the tuner is affected and throws off the frequency of each channel.

  • if it is the TV monitor's tuner rather than the cable box, then you would have to have it serviced by a repair facility.
  • if it is the cable box, just call your cable company to replace the box at no charge to you.
Good luck!
