SOURCE: vizio L42, wont turn on

Usually when this happens, the TV is in Protection Mode. When the TV detects something has gone wrong inside, the TV will prevent itself from turning ON.
Try leaving the TV unplugged for 30 -45 minutes so the TV can discharge and reset itself. If this doesn't fix the problem, most likely it's a power supply board related issue. At that point, you may want to get a price quote from a local TV repair shop. The cost of fixing the TV may exceed the price of a brand new TV.

I unplugged the TV and let it sit for about an hour and now appears to be working as before. Still strange, have never experience this before. I could understand no volume.

My Vizio flat screen tv won't power on sporadically! The Vizio name lights up bright and the Vizio icon appears in the middle of the screen but sometimes that's all it does.

Unlock it but forget pattern


So don't shove it up. Instead of that pull out the battery and it will turn off your tablet. Then follow this: Press volume up and down at the same time, when you have it press the power button as well until you can see the lights turning on. It might take a minute but keep waiting. When you got that release the power button BUT keep pressing the volume up and down if you are doing it right you gon see the Vizio logo and then it will change to a triangle with an exclamation sign it it. When you got that you can release the volume buttons then tap the home button and you gon have a menu what we call Recovery Menu. You will find the instructions there how to hard reset your tab. You will loose all your info but you can use your tab again :) If you got any questions, let me know :)

My remote wont work with my tv


The receiver for the remote is on the right side. Do you have something in front of it? My remote will not work if there is an object on that side of the TV.

For the 42" plasma, you need to change your sustainer boards or your main board to fix the problem. If your TV is still under warranty, call 877-MY-VIZIO and they will have a technician go to your home and fix the problem for free.

For the L42 HDTV, you need to change the inverter boards or the main board. If your TV is still under warranty, call 877-MY-VIZIO and they will have a technician go to your home and fix the problem for free.
