Only av input is working LG 42LC7D TV

Hi James,
The main board of your TV is not accepting HDMI input. You can use another AV input to watch the TV or you have to change the main board.

HDMI is an input to the TV not an output. You select the appropriate input e.g hdmi 1, hdmi 2 on the remote. There can be a return signal the other way but the cable has to support that. Try a different hdmi cable.

Tries tv and those cables or satalites boxes unplug,replug it back like about an hour later for those pay boxes to reboot and upgraded it softwares.Tv to do a whole resetting itself back to the factory setting.Than go into the tv Menu.Go into Video Setting,go down and do a resetting back to factory setting.By doing this steps for every components devices that hook to the tv HDMI hubs ports on the tv Tuner signal board to reboot and resetting too.Have very good chances all the HDMI hubs ports on the tv to work again.

Hi, it depends on the kind of TV your using...


How to Hook Up a Receiver to an HDTV

Though it utilizes the most sophisticated technology on the plant, an HDTV is extremely easy to hook up to a receiver. Home entertainment systems are designed for compatibility, whether it is a cable or satellite receiver, a DVD player or a stereo sound system.


Instructions

things you'll need:

* HD television
* HD satellite or cable receiver
* DVD player
* Stereo receiver
* AV cables
* Cable connector
* HDMI cables


Examine the back of your HDTV. You will see a series of input jacks for AV cables, (typically color-coded white and red for audio and yellow for video), as well as an antenna input and one or more HDMI input jacks. There will likely be a number of them, but each one should be distinguished with a label ("video," "cable" or something similar).

Attach the cable connector from the cable or satellite receiver to the antenna input on the back of the TV.


Connect the AV cables to the DVD player, VCR, stereo receiver or whichever other component you wish to connect to the television. The cables should line up by color: place the white cable in the white input jack, the red cable in the red input jack and the yellow cable in the yellow input jack. All three cables from each component need to go into the same label input jacks. Usually, they will all line up in a vertical row.


Find the HDMI output jack on your receiver or DVD player (some receivers will not have them--they are necessary to receive a high definition signal--but can still play on the TV through the cable connector or AV cables). Attach one end of an HDMI cable to the output jack of the receiver and the other end into the input jack on the HDTV.


Turn on the TV. Access the menu with your remote, and follow any instructions it gives you. Your HDTV may require a few additional steps to complete the hookup of the receiver (though not all of them will).


Access the "input" button on your TV remote. This will allow you to switch the TV signal to one of the cable connections you have just made. For example, if you attached the HDMI cable to the first of two HDMI input jacks, the TV will flash "HDMI 1" on the screen to tell you that is where it is receiving its signal.

Tips & Warnings

*

Not everything that can be hooked up to an HDTV is capable of playing in high definition. The signal needs to be HD as well, which means that only HD broadcasts, HD DVDs and Blu-Ray DVDs can play in full high definition (though "upgrade" DVD players will allow normal DVDs to play at an enhanced picture). You can still hook receivers up to an HDTV, and it will still play broadcasts from them as clearly as the signal permits.

This kind of tv u must have cable or satalite tvs pay broadcasting signal cable,so u have a box .Tv have HDMI ports or RCA AV component cable input?The incomming broadcating tv signal go to the cable or satalite boxes.Than u use a HDMI cable or RCA AV component cable go through those boxes than to ur tv HDMI input ports or RCA AV component cable input holes.

You have to change the input on your TV to what jack you are plugging into. Look on your remote for an input button.

Well, your TV is still under warranty. That's the good part.
The only thing I can recommend without voiding the warranty is leaving the TV unplugged for 30min. That way, the TV can reset itself and hopefully correct the problem.

If that doesn't solve the problem, it's time to use the VIZIO warranty.
