Sounds like The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts http://electro-medical.blogspot.com/ It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

We are trying to hook up a VIZIO sound bar model#S3820w-Co to our Vizio TV we also have Directv and a dvd player hook to this tv which wire do we hook from sound bar to Tv


If the TV and sound bar have an optical connector, then get the optical cable to connect the two. If not then use the audio out jacks on the TV and don't forget to change the audio set up to switch the sound to the sound bar.

Could you please tell me how to reset my tv? I have a blue screen


What should I do if my TV screen turned black, blue, or gray? print.png Print try this.

Proceed with the troubleshooting steps below only if you're seeing:
  • Black, blue, or gray screen
  • "No Signal" message without the DIRECTV logo
Note: If your TV screen appears "frozen" or you're seeing wavy lines or overlapping images, try this.
Solution 1: Check that your TV is set on the right input
[img border="0" alt="Image" src="https://cdns.directv.com/cms2/global/icons/sm_cl_blu__number1_icon.png">Turn your TV and receiver off and back on.
[img border="0" alt="Image" src="https://cdns.directv.com/cms2/global/icons/sm_cl_blu__number2_icon.png">Using your DIRECTV remote control, press the TV Input button to cycle through TV inputs (Component, HDMI, etc) until you see a picture. If nothing happens when you press the button, try programming your DIRECTV remote to control your TV Input and try again.

Note: You can also try changing the TV Input using your TV remote.

Still not seeing a clear picture?

Solution 2: Reset Your Receiver
[img border="0" alt="Image" src="https://cdns.directv.com/cms2/global/icons/sm_cl_blu__number1_icon.png">On some DIRECTV receivers there is a red reset button located inside the access card door on the front panel. Press it, then wait for your receiver to reboot.

Note: If you cannot locate the red reset button or your receiver does not have one, unplug the receiver's power cord from the electrical outlet, wait 15 seconds, and plug it back in. Then press the Power button on the front panel of your receiver and wait for your receiver to reboot.

Hdmi cables input 1,2,3,4 which input goes to the tuner, direct tv box, blue ray on vizio E550i-AO


The choice is entirely arbitrary. You may connect any accessory to any HDMI input. I recommend you connect the device you use most (probably your direct TV box) to HDMI 1, your second most frequently used device to HDMI 2, and so on, but it's really a question of your own preferences.

You need to make sure that is has enough signal, if you have poor signal, you will get pixels(as oppesed to snowy picture on CRT televisions) make sure all plugs are plugged in correct, and try diff inputs from DirecTV to the Tv to ensure its not the HDMI input thats faulty. Good Luck.

Vizio 42" LCD. Flat screen. Won't display CC on setup screen using HDMI input. Have a Sharp tv on another Directv box and it shows CC via HDMI connection. Problem with receiver or with TV? Costco's "Help"...


CC is a feature of the TV. All TVs are different in features and the Vizio is limited on its features due to cost. To eliminate the directv receiver connected to Vizio TV just swap with the receiver connected to Sharp TV and see if CC is displayed.
