Hdmi ports don't work

None of the 4 HDMI ports work. TV works, I can plug Tivo or Roku to TV using the red, yellow and white RCA plugs and these components work, but when I use any of the 4 HDMI ports there is a greenish-blue screen. I thought it was Tivo, so Cable company replaced Tivo and they don't know why the HDMI ports don't work.

Is the HDMI port 2 work? Try to turn it off and turn it back on. If it is still not working then the HDMI ports have gone bad. You will need to replace the main board.

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.
Here's contact info if you need it.

SOURCE: Vizio L32 32 in. HDTV LCD HDMI input not working

I recently had the same problem with my vizeo hdmi port # 1 going bad. Tried everything to fix and called vizeo. There solution for a master reset was turn off tv and unplug from the wall. then hold down the power button for 30 secs and let go. plug the tv back in and hold down the volume down and input select buttons down on side of the tv for 15 secs. release the buttons and turn the tv on after powering down all the components connectd to the tv. If this does not work they told me you need to have it sericed for a bad hdmi input. Hope this info helps anyone out there. It didn't work for me. Its a bummer cause the tv is well taken care of and only 18 months old. Best of luck to all others.

Does the DVD player have a HDMI port out ?
If so you need a HDMI cable
Or the DVD player might have an AV out port that is RCA ?

I have a DVD/VHS player that uses RYW RCA connectors and a new 4k TV that has HDMI slots, plus one yellow and one blue round slots, neither of which fit the RCA cables. How do I connect them?


The red, white and yellow plugs from the reciever will plug into the red, white and green input plugs on the TV. Be sure to select "AV" mode on the TV and not "HDMI". The Green plug on component inputs is the Video input. Otherwise you can find an adaptor that will go to your hdmi ports via the rca jacks!!

How to hook up a Roku2 to Sony KLV-S32A10 TV with A/V cable (yellow/red/white Ports)


If you plug into the box and TV with the composite plugs then you need to change inputs. Your TV is currently set to use HDMI. You need to change the source with your remote.

I can't get the video to work so I can use my roku. How can I watch roku?


Which way did you connect the roku? HDMI or with the yellow,red and white RCA cable? If you used the HDMI cable, look on the TV to see what number is on the input port. Select that number when you use the input button on the tv or the remote. Same goes for the RCA cables. Each input has a number next to it.

Connecting wii to Sony bravia tv


If you have an old V.C.R that has Red, White and Yellow sockets for AV and it still works then plug it into the RF socket tune the V.C.R to your TV and connect your Wii to the Red,White and Yellow R.C.A connections and you should be playing in no time. I have done this myself on a new Samsung TV it will work. If you have no V.C.R and you have HDMI sockets in your TV you can buy an adapter to convert the existing AV port on the Wii to HDMI then simply connect a HDMI cable (if you have 1 if not they are cheap enough off eBay starting at $6.00+AUD or around $20.00AUD Retail) to the Wii and then the TV ensuring that both the TV and the Wii are powered down prior to connecting any cables at the back. The HDMI Adapter for Wii is available on eBay from $5.00 AUD to $24.95AUD depending on the country you purchase it from. If all else fails a second TV with Red, White and Yellow RCA plugs will work but also the most expensive of the fixes. All fixes suggested will work. Good Luck I hope this helps.

I HAVECONNECTED ALL MY SPEAKER WIRES,HDMI CABLEAND CONNECTED THE YELLOW AUDIO CABLE.POWERED UP THE DVD BOX BUT I ONLY GET SOUND FROM TV.the tv is a new 47'' LG.


If you are using HDMI cable you will not be using the YELLOW RCA plug sine the Yellow pug is for composite video. Analog audio uses RED (RIGHT) and WHITE (LEFT) for sound.
How exactly youhave the whole thing setup? through the receiver or just between the TV HDMI port and the HDMI port on the DVD player?
You will also need to setup the HDMI sound set up to send the sound through the HDMI cable or through the audio analog RCA ports.
More info needed. Hook up per DVD and TV user manuals

I Have just bought this reviever (Yamaha Rx-v365)and im just trying to work out how to best connect all my devises. I have Tivo, Lg DVD player with both yellow, red white cables and blue green red cable...


Hi, firstly some terminology:
yellow cable - video composite (worst quality)
white/red - stereo analog audio
blue/green/red - video component (second best quality after HDMI)

You are correct that RX-V365 doesn't do audio over HDMI. Moreover it also doesn't do any video processing, which means composite video input will go only to composite video output (and not to component); compoment input only to component output and HDMI input only to HDMI output.

If you have more devices of same video output (in your example the component blue/green/red), you can connect them to TV via the receiver. But if only one device of same video output, you can connect it directly to TV. There is no reason to go through your receiver for video.

For audio, you can use either the analog stereo white/red cables (rx365 has 5 such inputs) or better use digital SPDIF connection, which is slightly better quality and more importantly supports 5.1 sound. There are 2 types - coaxial (orange RCA plug, can use basic rca cable) and optical (square black connector). Receiver has 1x coax spdif input and 2x optical spdif inputs. Look at your other equipment to decide which cable to use.

For the analog audio inputs, I think you can assign it either to composite video or component video. So for DVD audio white/red plugs, you can choose if either Video composite yellow plug named DVD will be used, or component blue/green/red named DVD will be used.

Hi, Just bought a 26" sony bravia tv. I don't use cable or satillite. I just need to find out what kind of cable I need to connect my panasonic DVD player to the TV and which port do I plug it into?


The best quality would be a HDMI cable, if your DVD player has a HDMI port on the back.

Any of the HDMI ports on the TV can be configured to take the audio over HDMI (digital audio) or over a separate rca stereo patch cable (menu option in the TV for analog audio).

So if your DVD has HDMI, just buy a HDMI cable and you're done. If you cannot figure out how to switch the audio input, there is no big harm in just installing a separate RCA patch cable between the two for the sound.

The next-best would be a component-video cable (Red/Yellow/Green) RCA cable, with a separate red/white RCA audio cable.

Alternately, if your DVD has a S-video port, that is comparable to component video. Then you would need a separate audio cable as well.

Last but not least, if your DVD player is ancient, it may only have a yellow video out connection, then red/white for audio. You then just need a standard yellow/red/white RCA component cable.

My wii connection is black and white


You are connecting it into the wrong input. The Wii comes with a RCA cables that should go into the Video (composite) input that has yellow, red, and white. The component input will not work with the RCA cable input. Plug your Wii into Video1 and you should get the right colors. There should be another HDMI on the side of your TV, there are inputs located both on the back and side of the TV for your convience.
