    Vizio Model# E370VL television
    I tried to turn it on after unplugging for 1 hour, but it would not stay on (only for a few seconds and then shut back off). It displays the Vizio logo on the screen and then shuts off. I called Vizio and spoke to a rep and went through the steps to try and correct this issue (uplugging the unit and repeatedly pushing the Input button and changing outlets, but nothing helped) the rep told me that she did not have any other ideas.

    I called our local cable company to see if they could help me, but they could not assist me as I needed to contact the TV manafacturer.

Please confirm the model number of this TV, is it a Vizio L37? I am checking into this now for you.. The first thing to try though is to just unplug the TV from the power source for a good two minutes, let it sit unplugged, then replug it back in and see if it still does not come on.

Let me know what happens when you do that, and confirm the model number.

    When it comes on, does it display anything at all on the screen? Or does the power light only come on, and then it all turns off again? I'd venture to guess that it doesn't come on past that, nothing ever comes on the screen?

    Yes this is definitely not a settings issue, or input issue even. It is actual hardware failure in the TV unfortunately. If you spoke to someone higher up at Vizio support they could confirm this for you. Sadly it could be a number of boards causing this, or even a flaky power supply that is causing one of the boards to short out. Do you have a voltage meter and would be able to take apart the TV and test the power supply to see if the correct voltages are coming out?

    Regardless though it is a hardware problem for sure... and is going to be quite expensive to fix even if you do it yourself.

    But let me know if you want to try and can test the power supply?

SOURCE: Vizio VX32L No Display and Can't Power Off

Old messages and bcipollina is gonna get to read this resonse twice; sorry-
If it just fails to turn on or ignores the remote, the main power supply is probably at fault and without some technical background and a couple of test instruments, you will not be able to do the repair yourself. 
What you can do though is; unplug the set, let it stand overnight or at least several hours, remove the back panel and look for a separate board with mostly larger components on it; it will have a ferrite core transformer on it and several larger capacitors which are cylindrical and mounted vertically to the board.

Before touching anything inside, especially on that board, allow several hours to be safe since the larger capacitors can hold a painful voltage charge for some hours.  
If you see signs of overheating such as discoloration of the board material, it may not be repairable but if you can find a part number on the board, you might be able to buy the power supply and install it yourself.
If there are no signs of heat damage to the board, there may be companies offering to repair it as a subassembly instead of repairing the whole set which could be much more expensive.
If you choose to replace or have it done, the power supply still may not be at fault since most are capable of switching on and off if a downstream problem is causing an overload.

BTW, from what I have read about Vizio, I think they are close relatives to iLo which was also sold by Wal-Mart.
Quality control anyone?

SOURCE: westinghouse LTV30w2 has blank screen and audio

What you have is a darfon V144 board (junk). it's a simple fix if you know how to use some basic tools and a soldering iron. Get an led (i used digikey's PN: L10041-ND) and solder it from pin 10 to pin 16 on the OZ960 chip on the inverter board. If you need the chip layout type "OZ960 pdf" in google. Hope this helps.

I had shut my tv off and was working fine before I had done so: I whent to turn it back on a few hours ago and when I turn it back on it goes to a blank black screen.

Sounds like the input might be incorrect? I would turn it on and hit the input button, make sure it is set where you want (for example, hdmi 1).

My 55inch LG 3D smart tv is not working properly. When you turn the tv on the LG home screen comes on for a few seconds, and then the screen goes black. What is causing this

it's set to the wrong input device ? the one you currently have it pointed to has no input

also it's possible that cable plugged into current input channel has gone bad or become disconnected from it's source
Hdmi cables are unfortunately famous for this as they have no Lock device to keep them inserted into ports

most TV's nowdays shut off if not provided an input for a few minutes

Blank screen

Any error message about inputs? Maybe that clicking sound happens when iit connects to the selected input, but nothing is connected. Can you scroll thru all the inputs? If so, turn on any devices connected to the JVC and scroll thru each input to find the one you're looking for.

Emerson TV no picture, but still have sound

If this is an LCD TV, show a flash light (torch light) on the screen from a safe distance.
If you can see the picture, the backlight has gone off and might need
of a qualified service technician.

I might of hit the wrong button when i was trying to switch inputs... The screen asked for 4 number password but i never had set one. So i just turn the tv off and on but now my tv shows vizio on the...

Dear Sir:
Follow this step:
Turn on the TV and grab the remote. In most cases, you will need the original remote to unlock the TV if you aren't sure of the unlock code. If you don't have the original remote, you will need to purchase one.

  • 2 Look at the screen. If you see a blank screen with a red key on the bottom of the screen, press 'Function' and 'Mute' at the same time. This should unlock the channel. This is an option for people who want the TV to stay locked but, want to be able to bypass the lock to watch a certain show or channel. All other channels will remain locked and the TV will fully lock when it is turned off.

  • God bless you

    TV screen goes blank but power stays on

    Sounds like the CRTs are going into protective blanking due to the vertical output ic needing to be resolderd. Try resoldering the vertical IC that may possibly fix the issue.

    Screen goes blank

    This sounds like a power supply problem in this DLP TV set. Best thing you can do is to call the manufacturer in the owners manual, or go back to where you purchaced the TV set and see where they send the Akia TV sets to be serviced. good Luck
