Samsung Plasma PN64D7000

Have you tried different HDMI cables?
Have you tried switching the ends around?
Are you sure you changed your TV inputs to the correct one?
Not all LG TV's will sense an HDMI connection and offer to switch to the new input.

I know it sounds ridiculous but I had an HDMI Cable break just sitting there. Also they now have HDMI Cable that are Unidirectional, you can plug them in backwards.

If you hookup your TV directly to the coaxial cable, bypassing the cable-box, do you get a few channels? If so, then the coaxial cable is carrying a signal, which is good.

How are you hooking the output from the cable-box to the input(s) on the TV? Coaxial output port on box to coaxial input port on TV?
Red/blue/green "component" outputs on box to matching inputs on TV? Red/White audio outputs on box to red/white inputs on TV? HMDI output from box to HDMI input on TV?

You have to "tell" the TV which of the inputs:
* coaxial (with TV set to Channel 3 or 4)
* component
* HDMI
to "listen" to.

make sure that the tv is in "HDMI" mode. If there are multiple HDMI ports on your tv then check to see which one it is. You should see HDMI 1, HDMI 2, etc. Then when you are sure what port it is in on either your tv directly or using the remote press the input button until the desired input is selected. So for example, if you have it in HDMI port one, press the INPUT button on either your tv or remote and cycle up or down until you select HDMI 1 and that should do it! sorry if it doesn't!

Depends on what type of ports your HP has and what type of ports your Samsung TV has. The easiest connection is to try to connect using the ports that they both have. Otherwise, if they have different ports then you will need some type of converter that goes between the two of them to make them communicate.

Most computers have a VGA port, does the Samsung TV have a VGA Port? New computers have a HDMI port, does the Samsung TV have a HDMI Port? If so you the connections that are alike or you will need a converter.

Once you have them connected, you just have to select the Input on the TV. Most times if you use VGA then you select PC or Computer as the input. There should be an HDMI input selection if you use HDMI connections.

Reboot the computer and the display might appear on the tv. If not you will have to hit some keystrokes to toggle the display between the computer and the tv. Most times on the computer you will hit the FN function key and one of the F1 thru F12 keys that controls the display on an external. The correct F1 thru F12 key will have LCD/CRT on it or it will have the icon of a display. Press and Hold the FN function key then hit the correct Function key (F1 thru F12) that toggles the display.

Most TVs will have HDMI and RCA component and composite jacks. Some TVs will also have a VGA port. Your laptop will have a VGA port. (If the laptop is fairly new, it may also have an HDMI port.)

Not all TVs will support an HDMI signal from a computer, so the VGA signal is often better. However, that limits you to SD (anything with HDCP will fail.)

Very few TVs ship with the HDMI or component cables. However, there are some vendors who do package the HDMI cable with their TV. Without knowing which exact model of TV and laptop, I can only make a few suggestions. I know that the TCP42ST30 (Plasma 42") doesn't have a VGA port.

Look at your laptop for any external monitor port. VGA ports are generally blue female ports with 15 holes (D-Sub). If your TV has a matching VGA port, get a standard VGA monitor cable.

If you have the VGA port on the laptop but not on the TV, you can try a converting from VGA to HDMI. (You may need a DVI to VGA adapter and either a DVI to HDMI cable or a DVI to HDMI adapter.) Note: this gives an analog signal (RGB format) to the TV. You'll also need to make sure that your VGA port is active (in the BIOS for some computers) and then set your computer to send the signal to the external monitor. It is best to turn off both the computer and the TV before connecting the two. Then turn on the TV and set it to the correct input before turning on the computer. (In Windows 7, I set the video signal for the external monitor by right clicking on the desktop and selecting Graphics Properties. Set the signal to the external monitor and click Apply. Then click OK (in the external monitor's screen).)

If this doesn't work, you need a VGA to component video converter. (Not a VGA to component video cable - those are for projectors that read the RGB signal.) See http://www.ramelectronics.net/audio-video/video-converters/vga-rgb-hv-to-component-video/c10000-c11200-c11215-p1.html .

Some laptops come with an HDMI, mini-HDMI or a DisplayPort option. For the latter two, you will need the appropriate cable with that end and the HDMI connector on the other. Then connect the TV and the computer as described above. (Note: my TVs accept a computer signal at the HDMI port labeled HDMI/DVI. However, you need to make sure that your TV understands this signal. It isn't the same format as that from a set-top box. My laptop has VGA and HDMI out; the desktops have VGA, DVI and HDMI (on one).)

If you add a comment with the model of your TV and laptop, I'll be glad to give you more specific options to connect the TV and the computer.

I hope this helps.

(A DVI port is a digital video out option with ~21 pins and is usually white.)

If you just bought the PS3 use your composite cables that came with the system. Turn the PS3 on and go to the video settings, set up video input to HDMI. After you've done that plug your HDMI back into your PS3 and try turning it on. If that works go back to video settings and change the resolution to 1080p. If that doesn't work make sure your T.V. is on the same input that the HDMI cable is plugged in. If it is and still doesn't work try switching to a different HDMI port. If switching to a different HDMI port doesn't work try a new HDMI cable. If the new HDMI cable doesn't work then there is a problem with the port on the PS3 which would require a repair.

Hi,things you will need,

• Video game console
• HDMI cable
• Audio/visual cable.

1. Plug in your video game console's power source.
2. Connect one end of the game console's audio/visual cable into the corresponding slot on the console if you have an older game console. If you have a newer console, insert one end of an HDMI cable into your console's "HDMI OUT" port.
   
3. 
   Plug the red and white ends of the audio/visual cable into the corresponding red and white audio inputs located on the back of your Vizio plasma TV if you have an older game console. Plug the yellow cable into the yellow "Video In" input. Depending on which model of Vizio TV you have, the yellow input may be located either right next to the audio inputs or it could be located a few ports away.
   
4. 
   Plug an HDMI cable into one of your TV's "HDMI IN" ports, if you have a newer console.
   
5. 
   Turn on your video game console and your Vizio plasma TV. Press the "TV/VIDEO" button on your remote to cycle through the various inputs. You should eventually get to an input that's displaying your video game console's home screen.
   

I think that will do.

Have nice day.

video input malfunction.....

Hi.

To start ensure that each time you connect or disconnect the HDMI ports both TV and connected device are off.

Also ensure that HDMI input is active, as detailed here.

HDMI connectors carry voltage, and connecting the HDMI cable while TV or device is on may easily damage the HDMI port, making it unusable.

The HDMI 3 and Component 3 are separate input. The component input may work, and HDMI port may still be defective.

To test the port do the following:

Disconnect TV power cord, and connected device (eg. Receiver, DVD etc.).
Leave units disconnected for five minutes.

While power is disconnected, test connecting on port three a device that was previously working on HDMI 1. Also use a cable that you know is working.

Connect back power with HDMI cable already connected. If HDMI 3 is still not detected, then the port is defective.

In that case ring Pioneer at the number listed on the owners manual.This model is often advertised as only two HDMI inputs. Call Pioneer to ensure the third port can be enabled.

The HDMI input along with others is located on the a/v control panel of which would have to be replaced. I haven't seen an input jack yet with a part number attached for any model. I would suggest call a service center for a diagnosis.
