Question about Vizio Televison & Video

1 Answer

Out of no where my Vizio won't show cable, Blue Ray, or shows on Roku. One of the HDMI ports hasn't worked well for awhile so would have to switch HDMI ports to watch Roku or Blue Ray, but overall worked ok. 2 days ago can't get anything to work. Hand I first turn on Blue Ray main screen that says brand name shows up then goes black also can turn Roku on & browse through shows/channels/movies but when I try to play anything a pale purple screen says HDCP UNAUTHORIZED can hear sound but no picture. Cable tv doesn't show anything not even tv guide. Tried different HDMI cords & even bought 2 new cords....still nothing..TV is about 3 yrs old. Any ideas?

You may need to change the HDMI board in the tv. it will be the hole board the parts are just to small to replace them all to get the HDMI board working again. find a second hand replacement. should be fine with another known working one.

SOURCE: TV wont detect HDMI Devices except a pc.

Something is wrong whith the HDMI jack it's self, or the electronic switching is not sensing a signal is present. In either case the board that has the HDMI jack you are using needs to be replaced. Most all these boards are double printed, Multi-layered or both which prevents replacing the jack it's self. I do have a question though, do you only have on HDMI jack on the unit or do you have another one available.

I haven't had any problems with my VIZIO, but I have had several really good experiences with their service people, so I would recommend calling them up. They have great product guaranty and if for whatever reason you got a defective item I'm sure they'll help you out.

SOURCE: I have a VIZIO LED/LCD VF551XVT hooked up to a

I have the same set, same problem with one of my MOTOROLA boxes, but not with another. I have a SONY TV that works fine with this new MOTO box, but the new VIZIO does not. The audio is coming through the HDMI cable just fine, and the fact that it works when you cycle power on your TV means it's the SYNC between the TV and the BOX. I have the identical problem and am taking back the MOTO box for another one. I spoke to VIZIO for about 45 minutes trying different things. They think it's the MOTOROLA box, COX (my cable company) thinks it's this particular box, who knows.

SOURCE: "No signal" sign on TV screen using HDMI selector

it sounds like a refresh issue, double check you selector and make sure it fits the refresh of the tv. i had this once with a sharp where the tv was 120hz and the selector was 60 and it created a no signal and when it did come in it was jumpy. if you have a 120 tv then selector should be the same.

Vizio model VA26LHDTV10T roku stick will not fit into HDMI port. Stick too long. How can I connect roku stick?

Get a short HDMI cable extension, with a male connector on one end and a female connector on the other. Best Buy may offer them. There is also a very short HDMI adapter that allows up to 90 degree turn so the Roku will lie outward., also available at Best Buy or TV specialty stores. Finally, try using the HDMI side port on the TV's right side (to your left as you face it).

Vizio tv says no signal on any of the hdmi ports

Unfortunately, you fried the HDMI controller. Not necessarily part of the power supply "main board." (Not sure which board is the HDMI controller in your specific TV. It's usually a separate board by itself). Easiest workaround is to use the "Component" cable connectors. The downside is you only get 720P. However, most cable/satellite and _all_ antenna signals are only 720P anyway. Most people only see 1080P when viewing Blu-Ray discs. Aside from replacing the HDMI controller, the cheapest workaround for multiple source connections is to buy an HDMI to Component Converter A/V box, which allows you to connect multiple devices to one box with one set of Component cables connecting to the TV. Then select various "sources" via the box.

Just hooked up the streaming stick to HDMI to the TV. nothing is showing up, What do I do now?

Sounds like you have a bad connection on either your roku stick or your HDMI PORT.Does you ROKU stick show a white light if not check power cable or electrical plug.
Try wiggling ROKU stick just a hair or push it in and out until you get a signal..A purple screen with the words ROKU should show up on TV.If you have a bad port on TV it would have to be replaced but this is rare,if you have a second port on tv try that.Have you tried your ROKU stick on another tv?Does your streaming stick go in vertically or horizontally,if it goes in vertically it may be pressing against side of tv prohibiting a good connection.You could try a HDMI cable, plug the HDMI cable into tv and put ROKU in other side of cable.There is also a restart button on ROKU stick push it and it will start blinking,if it doesn't light up you may have a defective ROKU stick.

Sony KDL-40NX711 HDMI PORTS STOPPED WORKING. EVERYTHING ELSE WORKS FINE. WHAT WOULD CAUSE THIS TO HAPPEN?

Sounds like everything works. Your remote has an input menu. Have you cycled it around to the right component? i.e. HDMI1 or HDMI2, or DVD, even PC?
If not, try that.

My blu ray 3d dvd player will not show picture on blu ray discs only sound but will play regular dvds correctly

The video for blu ray disks come out of the HDMI port and that has to be connected to the TV for video. If it is connected, make sure the TV is switched to the correct HDMI port on the TV (assuming you have a flat screen HDTV).

LG blue ray won't play sound from RCA sound bar. HDMI cable is hooked into HDMi slot on TV

the details you provided were very vague, however from my experience when a device is connected to another device via and audio capable hdmi cable, that device renders it audio output to the device its connected to and normally turn off all other audio outputs beside optical- I would assume there is an option in the blue ray player to turn off hdmi audio, which will in turn activate other audio outputs- you may also look for audio out port on your tv, it is ideal to connect the sound bar directly to the tv set audio out ports. To sum this up,
if you plan to use your player via hdmi cable you need to turn off hdmi audio output on the blue ray player and the plug an audio cable from your blue-ray player to your sound bar
you may also as i said connect your sound bar directly to your tv, the issue is most tv sets now a days do not have an audio out port, if you do then everything you play thru your tv will have audio via sound bar
there are several way to go here but unless your sound bar has hdmi av switching capabilities (im sure not) this is one of the most simple--Good Luck.

My color is showing but its mostly blue and yellow and the red is not showing at all

If you are using composite cables one of the three cables could be bad. Try re seating the cables. If it is a HDMI cable try a different HDMI port. If still not working try swapping cables from another device. Also make sure you are choosing the correct source on your remote.

How do I get from 480 to 1080p on my tv? I have an HD box on my vizio 42 inch tv but my channels are still showing 480?

1080P is a quality you'll only get with a blue ray quality video. Therefore, you won't get 1080P on cable tv. If your cable provider has HD channels available, you'll be able to get 720 or 1080i quality video (on those channels only). For the best quality, make sure you are using an HDMI cable. Just be sure your cable box supports an HDMI output. Your Vizio definately supports that type of input. If you have a PS3 or alternative blue ray player, you'll be able to watch 1080P.
