Hi, you ever find a solution for these issues? I've got the same things going on over here. Started happening after last month's firmware update. I've also resorted to turning the tv off and then back on again to get the video going, but lately I've had to do that at least twice before the video comes on. Unable to stream from my Plex server on the same network now as well. Finally got fed up enough to check if any others were facing similar issues.
Unfortunately, I continue to have the issue. I did send in a request to Vizio support. The following was their reply:
Thank you for your recent inquiry with VIZIO. I would be more than happy to help you. I apologize to hear you are having difficulties with your VIZIO TV. I would recommend performing a power cycle on your TV and re-seat all of the devices that are connected to it. Please follow the steps in this order: 1. Power off the TV. 2. Unplug the TV from the outlet. 3. Disconnect all devices from the TV. 4. Press and hold in the power button on the side or back of the TV for 30 seconds (while it is unplugged from the wall). 5. Release the power button. 6. Plug in the TV. 7. Reconnect all devices. 8. Power the TV back on. Please also try to reset the unit. If you have a menu button please follow these steps: 1. Press the Menu button on the VIZIO remote 2. Select the System option 3. Select Reset and Admin 4. Select Reset TV to Factory Defaults The TV will restart and begin the initial setup again. If you have a cast model, please locate the buttons on the side of the TV, you should find 4 of them. The bottom two would be input and volume down, these are the two we need. You would need to press these two together for 5-10 seconds, until a bar appears on the top of the TV. Then, you need to press the input button (the bottom button) for 5 seconds, until the screen goes black. This would cause a factory reset to the unit. Once this is completed, please follow the prompts that get displayed to set the TV up once more. You will need to re-pair your smartphone or tablet using the VIZIO SmartCast application during this. If no change after either, please test another device to the unit. Does the second device have the same issue? If so and you have had the unit for less then a year, please provide us with this info: -The serial number of your device -A copy of your receipt -Your physical address -A valid contact phone number -A photo of your full TV, powered on, with the issue present (if applicable) If over a year (& not purchased through one of the select few retailers like Costco or HSN) then you are outside the one year warranty provided by VIZIO. By all of the symptoms you've explained you are going to need the TV repaired. I do not have the schematics of your TV in order to diagnose this. You would need to consult a technician in order to properly diagnose the issue since many issues cause similar symptoms. I do not want to advise you of anything specific, and have you purchase the part and end up wasting your time or money. Unfortunately the cost of repair or part is not determined by VIZIO but by the parts/repair facility, however if you contact them they will be able to give you a quote. VIZIO currently has one partner company who is certified to perform repairs on VIZIO TV's. You can reach them at ITI- (888)248-2708. ITI's hours are Monday-Friday 8am-8pm Central. Thank you, Ashton VIZIO 800 Stevens Port Drive Suite DD750 Dakota Dunes SD 57049 Phone 877-878-4946"
I had already attempted the steps provided above (both of them, due to the excellent help found here) before sending off my request. It looks as though I will have to call in some diagnostic help to fix, what is probably a board that went bad. That, I have yet to do. I may just scrap it for a new set, and use it as a secondary set, with the added bonus of turning it on/off twice. Please keep us updated if you find a solution.
