Samsung TV--fire hazard??

Possibly a bad HDMI cable connection. Remove cable,
then reconnect, with the plugs firmly in the jacks. If that doesn't
work, then borrow an HDMI cable from a friend and see if that
fixes the problem.

First what make/model of TV do you have? Does it have a digital tuner? (Manufactures had to add digital tuners at various times depending on the TV size)

Next what type of antenna or cable (basic, digital) do you have and how is it connected to the TV? Is it an indoor or outdoor antenna and is it pointed at your area stations? See antennaweb.org or tvfool.com for details on where your local OTA stations are. (Note: antennaweb assumes an outdoor antenna but is very conservative in their list.) Antennas can be turned by the wind.

Do you have an amplifier or a splitter in the system?

First, remove the amplifier or splitter and try a direct connection to the TV. (I've had amplified splitters turn into signal filters after they failed. Then they gave no signal out from certain bands. Many areas only have UHF digital stations.)

Next check your cables for damage and try replacing cables. (I recently had a cable in the wall get damaged and had to rewire that outlet. The TV got good signal if I ran a direct line across the floor to another coax jack.) Alternatively, try connecting the TV to a different coax jack.

The final thing to check is the TV's inputs. They can fail. (I lost a few analog TV tuners to a lightning surge.)

I hope this helps.

the hdtv you bought is not the right kind for avs and component cables.
yes, i know its a pice of **** now that i explained it. if you still can return
the tv get a different one like a panasonic or a sony anykind exept samsugcuz they r *******

Follow these steps: Component Video Connection 1. Get a component video cable. This cable has 3 sets of connectors, one each for the red, blue and green color signals.
2 Match the connectors to the appropriate video output jacks on the DVD player. Component video outputs will normally be labeled Cr/Cb/Cy. The Cy output jack is matched to green, Cr to red and Cb to blue.
3 Run the cable from DVD player to the TV. Most TV connections are made from the back panel, but this may vary.
4 Match the connectors to the appropriate video input jacks on the TV.
If using S-Video Connection
1 Get an S-video cable. This cable has a single round connector with 4 pins.
2 Attach one end of the S-video cable to the S-video output jack on the DVD player.
3 Attach the other end to the S-video input jack on the TV.
Composite Video Connection 1 Get a composite video cable. These types of cables are frequently bundled with two-channel audio cables. Composite video cables are tipped with yellow plugs.
2 Plug one end of the composite video cable into the composite video output jack on your DVD player.
3 Plug the other end into the composite video input jack on your TV.

You might want to check the sleep timer. Go into the menu and make sure that this is not the problem first.

Let me know if i can help you further.

So you are connecting the laptop to the TV using VGA port of the TV, right? To get sound in the PC input mode, you need to use the PC audio input jack (green jack, mini 3.5mm jack) not the RED and White RCA audio input, they are for Composite Video AV inputs. That is how I have my laptop and TV setup to watch Netflix.

Connect the RF (cable wire) to the CABLE RF jack on the back of the TV. It sounds like you have it connected to the AIR RF jack. Next, press the ANT button on the remote. Not go into the TV SETUP menu and do the auto program again. This should fix your problem, best wishes.

Hello,

That does depend on the PC, but I'll assume it's a pretty standard PC.

You ideally need a Male 15Pin VGA cable to Male 15Pin VGA cable. (aka A normal Monitor Cable) The same as you probably have connected between your PC and Monitor.

Your TV has a 15Pin VGA Female socket on the back, this cable plugs into here.

For Sound the TV has what looks like a headphone socket next to the VGA Plug. You need to use a Stereo Jack Plug to Stereo Jack Plug Cable. 3.5mm. This goes from your PC's Audio Line Out (rear of the PC) to the Plug on the rear of the TV. It is usually marked Aux In or PC Sound.

Enjoy, The PC will look great on the Tv.

Yes it can be replace only if it just a connector adapter connected independently unto tv tuner. But if it is with the tv tuner as a whole. You will replace the entire tv tuner. Just bring the part as reference to your favorite electronic store selling tv parts.

The TV should have two ANT coax jacks in the back, one for air and one for the cable line. The one on the right side should be the one you want. It could be that you've plugged it into the left one, which will not work for line cable.
