SOURCE: No surround sound when attaching hdmi to TV

Try running the optical TOSLINK cable from the TV to the receiver. If the TV doen't have a digital optical output, then try going into the menu on your cable box and setting the audio output to the digital optical out. Also check your TV menu and make sure NETCOMMAND is diabled. Some of your newer HDTV have Netcommand that allows the TV to control other devices through the HDMI cable.

SOURCE: The LCD screen is dark with no sound or picture when turned on.

I had the same problem after having a Vizio for 2 and a half years. I left the room for a minute, i came back and the screen went black. There was still power to the unit and you could see that the back light was working, just no picture, no sound, and you couldn't use any of the buttons. The only way to turn it off was to unplug it. It would then start up, with the Vizio logo going from orange to white, and then do the same thing all over, no pic or sound.

HOW I FIXED MINE:Look through the back vents for a white light to make sure the backlight still works. I ordered a new "main PCB" from tigerdirectparts.com (you can also use searspartsdirect.com). This is the circuit board with all of the inputs on it (hdmi, cable, etc.) I opened it up, disconnected the old one, put in a new one and now it works fine. I used both serial numbers on the board to search for it online. It cost me $144 to do it, but that's better than $450 for a new TV. My tv is the vx32l hdtv10a. I hope that helps.

For me the part number was either (depending on the vendor) : 0171 2272 2174 or it was 3632 0212 0150. Check your circuit and see if any of those numbers match up.

SOURCE: HDMI signal cuts out for

Mine did the same thing where the screen would go black for a few seconds and then the picture and sound came back. I would try (1) switch HDMI cables, (2) try a different HDMI input in the back of the receiver, (3) try different input in the back of the TV. None of these seemed to work with mine. I finally ended up running the cable box direct to the TV and only run the audio through the reciever via coax or digital. No more problems. I think the HDMI inputs in the back of the reciever have a problem continuously carrying the signal if it is the leaset bit weak.

If you are trying to connect it in composite mode (the one yellow video cable) it won't work with the PIP turned on which is how it comes from factory. This is crazy as it means that you cannot see anything (menus) on the screen to disable it. I have a walk through guide here to turn it off blind or the other option is to take the STB and connect it to another TV via Component or HDMI and then turn off the PIP.

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.

Error message: HDCP unauthorized. Content disabled. Get audio but no visual


It is a Roku vs TV interpreation of HDMI. IMO it is Roku being too protective. No other box in the house has a problem with any of TVs or cables. New cables did nothing and the cables were the latest and gold plated. Reboot the Roku and it works....for a while until it comes back.

Some TV's & cables are not HDCP compliant . Sometimes you can replace the cable to fix the problem & other times you have to replace the tv because its not HDCP compliant . First check to see if your tv is HDCP compliant .

How do I connect my new roku?


You could see something for sure.

Verify the input you have the Roku plugged into is the one you currently have selected on the TV.

If that doesn't work, plug use a paperclip to press the small "reset" button button the Roku.

You can also choose to perform a hard reset:

Hard reset

If a soft reset doesn't fix your problem, a hard reset may be your only option. This will clear all data off the Roku 2 and reset it to factory default settings.
1. Remove all cables except the Power cord.
2. Using a paper clip, press and hold the Reset button on the back of the device for about 15 seconds.
3. Continue to hold the Reset button, then remove the Power cord from the back of the unit.
4. Release the Reset button, then plug all of the cords back into the device.
The Roku 2 should walk you through the setup process again.
You can also accomplish a hard reset by selecting Settings > Factory reset > Factory reset > Yes on the device's menu.

Finally, try using a different HDMI cable.

Let me know if any of this helps.

Can roku be used with a cable box or do I just have to use one or the other?


If you have another HDMI port or A/V cable available on your TV, you don't have to unplug the cable box from the TV. You'll only need to connect the Roku to the vacant Input ports (HDMI or A/V) and change the input source of the TV accordingly.

WE JUST BOUGHT ROKU , HOOKED IT UP , CAN'T GET ANYTHING ELSE TO COME UP


Hi,

You must match the TV's input connections and the Roku output on your remote. This means if the Roku's output is connected to your TV's "HDMI 2" (or A/V 2, etc.), you must be able to select HDMI 2 (or A/V 2, etc) on the TV - either with your remote or pressing a button on the TV itself.

Sometimes, the TV will skip over unused inputs when it was first set up. This is done to reduce the number of button presses to go from say "HDMI 1" to "HDMI 4" by programming OUT the HDMI 2 & HDMI 3 choices.

You'll need to program IN the input that your TV uses to connect the Roku if it isn't already available. You MUST connect cables properly if not using HDMI. RGB is Red-Green-Blue and must be connected to RGB jacks at the Roku and TV for a picture and the the White & Red (left and right) audio must connect the the corresponding Red / White audio jacks - or it will provide strange results.

Make sure the power plug is connected to an outlet that is ON and connected to the power jack on the Roku box itself. Unless you have a defective Roku box or TV, it SHOULD work. You can try using a different HDMI or A/V jacks on the TV to determine if it is the TV jacks or not.

Good luck!

My roku streaming device is froze on this blue screen and will not change?


Glenda, Are you connected to your tv by HDMI or AV cables?
The blue screen is usually an indication of one of two things.
1: The HDMI cable has come loose but not entirely disconnected (Turn off Roku and TV unplug the HDMI cable from the Roku AND Tv and reconnect them making sure to seat the ends securely and turn on TV and Roku in that order)
2: your TV or receiver may not support HDCP (a content copy-protection solution) over HDMI. This is generally true for older TV models that have early HDMI implementations that do not follow current standards. Try connecting your player with the included A/V composite cable instead.
