I WANT TO USE THE VIDEO COMPONENT INPUTS. What do I have to do? The display says no signal, even though I have the inputs connected to a video source. It wants to get a tv signal.


The signal that tells the TV that the source is on is broadcasted over the Green connection. Try another cable on the Green only. You won't get color, but you should get a picture. It could just be a bad cable. Some TVs you can Skip or Deactivate your inputs. Go into the menu and make sure the input is active. Lastly, whatever piece of equipment you are hooking up make sure it is set for Component and not Composite.

I bought a new samsung led 5 series tv but it keeps telling me i got no signal. the only connection i have is the antenna cable but it keeps telling me i got no signal even though iv done the whole auto...


Hi there,

Do you live in a house or some sort of complex? If you live in a home, then I would suggest verifying the connection to the outside antenna. If you live in a complex (apartment, condo, etc.) then the possibility exists that there is no outside connection (to any broadcast source) except for cable.

Good luck with that TV, my parents bought one in January and the picture is amazing.

Hope this helps some.

My lg tv (had since Nov) says no signal for the tv or dvd player. How do I fix this?


Try unplugging all inputs and the power cord from the TV for 5 minutes. This will allow the main board to reset.
Next, just plug in the power plug to the TV, power up the TV, and even though there is not a source connected to the TV, check at least three inputs and see what the TV will report on the screen for each input.
Next, turn off the TV, plug in all known working devices (Cable/Antenna, DVD, Blu-Ray, Cable/Satellite box, Game, ….) with a known working cables to the TV, make sure all the devices connected to the TV are powered up and on, and now power on the TV.
Now check to see if the TV is seeing valid signal for all the inputs connected to the TV.
If your TV cannot see any signal at any of its inputs (HDMI1, HMDI2, HDMI3, AVI1, AVI2, Component1, ……), then the main board has failed and need to be replaced.
Good Luck.

No Input Signal when PS3 is connected to TV

We have cable T.V. should we run the cable though T.V. when we use s-video cables or use cable though vcr then T.V.


I would hope that you would use a HDMI cable to connect your cable box to your LCD TV - why not display the highest resolution to your screen that you can. HDMI will transmit the 1080P high def signal to your screen. These cables can be found at Wallmart and Target or even Best Buy. Don't need the most expensive and or a 6' length or short will work just fine.
Then use your S-Video cable to connect your VCR/DVD to your LCD TV - This is not a High Def signal - only 480i if that. The P means Progressive or 1080 lines from top to bottom. the I means Interlaced to which means 240 lines once for field one then 240 lines for field two.
You may want to think of a blue ray player to which upconverts your older DVD's to 4x3 High Def resolution.

The screen shows ''Weak Signal'' and no picture, even though audio is coming through from both the Cable DVR box and Blue-Ray player. The cable box connects to the TV with an HMI cable - all five TV inputs...


Mine did the same thing once. I think all I did was hit the setup on the remote, and let it run back through all the channels and then it worked just fine.

I hope this works for you.

Trouble connecting DVD


NEWER TV SETS REQUIRE THE RIGHT CABLES, USE S-VIDEO OR AN HDMI CABLE WILL SOLVE ANY PROBLEM
ALSO SOME T.V SETS ARE JUST LIKE THE PLUG AND PLAY YOU HAVE WITH COMPUTERS, ONCE THE RIGHT CABLE IS CONNECTED AND YOU CHANG TV INPUT FROM YOUR REMOTE IT WILL PICK UP YOUR DVD

Surround sound


Hi

Your receiver is capable of video conversion, so there should be no problem using your component cable.

Does your TV accept component, or only S-Video? If you can run component to your TV, the best quality signal path would be using a component cable from your Verizon box to your receiver, and component from your receiver to your TV.

Make sure you have set up the video input correctly, so that it is set to accept the incoming signal on the correct sockets.

Multiple video inputs


Unfortunately, you cannot use the connectors at the same time. The S-Video connector overrides the standard video connector. This is why they share common audio left/right inputs. If you could use them separately, they would each have their own set of audio inputs. (S-Video does not carry audio signals on the cable.) I'm assuming that you are connecting your Satellite as an input to your VCR, and then your VCR to the TV via a video connection. The VCR passes the satellite signal through unless you are watching a tape, then it overrides the dish signal. You have a few choices here: 1. You can connect the coaxial (RF) output from the VCR to the TV, and watch the satellite and VCR on channel 3 (or 4). You can then connect the DVD via S-Video, and watch it on "video". This is the simplest solution, and provides the best picture quality for the DVD (with this TV), but lower quality for the dish and VCR. 2. You can connect the DVD player via RF (if it supports that), watch the DVD on channel 3, and connect the VCR via video. This will make the DVD picture quality terrible. 3. You can replace the VCR with a combo DVD/VCR unit. You can then connect the S-Video out from the combo unit to the TV. This is a more expensive solution. 4. You can replace the TV with a model that includes more inputs. This is the most expensive solution, but will allow you to watch your DVD over component cables (very high quality) and VCR and dish over S-Video. Ironically, the obvious choice, connecting the DVD as an input to the VCR (as a pass-through) simply WON'T WORK. The signal put out by the DVD player is "copy protected" (using a system called MacroVision) which the VCR will refuse to play, even as a pass-though. Best of luck with this. Given that you are trying to make this all work without replacing equipment, I recommend option #1, until you decide to break down and buy a shiny new HDTV. They are coming down in price every week, but only you can decide when the time is right.
