    L42 won't power up!

  • Sashas Jun 10, 2008

    Same here - remote is dead; I tried to turn it on manually - dead, too. But the yellow (standby ?) indicator is on, so it seems to have power supply.

    anyone have a solution yet to the tv not turning on??? mine just stopped working last night. standby "vizo" light turns on so i know there is power but screen is just blank. 

  • Anonymous Jul 06, 2008

    Mine won't turn on either. There's nothing wrong with our power supply. I'm not sure how this is a solution.

    Ours did the same thing 3 days ago. We turned it off when we went to bed and when we got up it wouldn't come on. The yellow light is on, but the screen stays blank. The warranty just expired, wouldn't ya know. Technical Support asked me to try the "old standby", turn it off, wait a minute and turn back on, but it didn't work. Their only other suggestion was to call a certified Vizio repair service.

    Same problem, started having problems to turn on and then didn't turn on anymore and ligth is yellow. Tried to unplugge it but didn't work.

    My tv is a year old and it started 6 months ago to do weird things. It would come on but only the sound would work and not the picture, it was just a black screen. We turned it off and then on again and then it would be fine. This happened a few times. Now today we turned it on, a few seconds of working then went black, now it won't turn on. The yellow light does not come on either. This sounds a little different then the other's problems, does anyone know what I can do?

  • herbola Jan 16, 2009

    I have a very similar problem. When you press the on botton, the power indicator turns from yellow to green, but the screen and sound never come up. After 5 or 6 seconds the indicator returns to yellow.

    My L32 is about 4 years old and after 2 years the screen would randomly go blank but the sound was still there. Typically within 10 seconds it would be back to normal. Again it went blank but this time it didn't come back on. Brought it to a TV repair and they said it was the "main light" powering the LCD... so I'm tearing into it and found that I can get the normal looking screen for 8-10 seconds then the power goes back to stand-by. I can repeat this brief operation over and over again. I ordered a new main board (3320-0032-0150) based on some of the posted solutions. Was this the right action?

  • bjd33 Jan 27, 2009

    8 days ago my Vizio 32Lhdtv10A made a loud pop (gunshot loud) and went off and would not come back on. Even the standby power light was out. After reading some of these posts I took the back off and saw a charred black area and apparently a blown resistor/transistor on the power supply board. I ordered a new one using the part number on the board (0500-0507-0180) but was sent a different part (0500-0502-0102). The part supplier says these are interchangeable parts but the tv still won't come on or show even standby power. Any suggestions?

    my vizio 42" will click on but just to a blue screen that says NO SIGNAL, then it proceeds to turn off by itself

    You need to send that particular part back and insist on the original one that goes to your tv . Be firm about what you want. Your television was not made with "interchangeable" parts. Also look at the other components around that charred area and see if there are any others that might need changing

I bought my 42" plasma Vizio 17 days ago and this problem just happened to me. We were watching and it just went off and it won't come back on. The tv clearly has power as the yellow light is on, but this tv simply won't come on. I called Walmart to verify I could return (I can) and they said they have two others that were returned sitting in back. I imagine this is going to force Vizio to do something soon, I can only imagine how many of these things are going to start failing in the years to come.

Ck u33 on main board part number 1117 reg. ic

Posted on Aug 27, 2014

Had same problem. Replace main board and now works just fine. You need to take the back off and under the metal cover in the center of the tv is the main board. The part number should start with 3320-xxxx-xxxx. Don't get confused the power board is on the right side and the interverter is on the left side.You can purchase the board from Vance Baldwin. sign in as a guest. I will warn you the cost of the board is high.

I solved it long time ago - just unplugged it for a minute... Though this model doesn't seem a happy one - my sound sucks.

My TV won't come on

Hello Linda,

The set will need to be diagnosed to find the problem. There could be an issue with the power supply or main board but get it checked out.

Won't power on

Check your power outlet for any loose contacts and ensure there is power. Try connecting the TV to a different power outlet.

Switch off TV manually, switch off power, remove plug and retry after 48 hours.

If problem persists, please refer it to a qualified service technician.

My toshiba 32av500u wont turn on

Please check the power outlet. Try changing to a different power outlet. Look for jammed on/off switch on remote or on control panel of TV. If nothing works, better refer it to a qualified service technician.

My tv dont want to turn on

Check power connections. Try different power outlet.

If it simply wont do anything,. you will need to contact Vizio. It is possible the tv has simply fried itself.

No power coming through even red light won't come on tried different cords. That didn't work either. And we had the tv on a surge strip along with the computer and it is fine.

Try plugging the tv in a different outlet in the strip. Maybe the outlet it was plugged in during the surge got fried. I would bet thought the fuse on the power supply has blown and needs replaced. You will have to take the back cover off of the tv to find the power supply. Good Luck!!!! Hope this helps.

It won't turn on

I replaced 3 capacitors and fixed this problem. They were 1-10v 1000uF and 2- 10v 3300uF electrolitic board mount capacitors. Easy to spot on the power board, the tops were bulged up. $5.54 later it works perfectly now.

My vizio 32" LCD TV will not turn on and the standby light will not come on either.

First try plugging the tv into another wall outlet, see if the one its in now is off. Make sure the ac cord is well fitted into the tv and the wall outlet. If still no power (and no warranty left on the tv) remove the back cover and check the fuse if blown replace it. If the fuse is good then the power supply board needs to be tested. If you know someone who's technically savy let me know I'll walk them through some testing steps to find the problem. Get back too me..

This is the best I can do over the internet.......

32 inch vizio will not turn back on, just stays orange in front

Try unplugging the tv and holding down the power button for 30 seconds than pluuging it back in and if it does not come back on the tv will need a repair to the power supply, just call tech support and make sure to have the serial number and the reciet handy so they can get you registered on the support system. Hopefully your tv is still under the one year mark than the repair will be free if not it can get expensive fast. Me personnaly have worked for vizio for about a year now and honestly this is a very common problem with theses tv's.

No Power to a Vizio VX32L

My best guess is to check for blown fuses or the power board when bad inside the TV.
If that doesn't work, looks like you'll have to pay a repair shop to find out what's really going on.
Sorry I can't help you further.
