Question about Vizio P4 46 in. HD-Ready Plasma Television

6 Answers

Vizio plasma tv turned off..won;t turn back on

Our tv, which is 1 week old, just turned off by itself and we can't get it to turn back on by remote or by pushing the on button manually. There is power because the cable box is on along with the stereo which is hooked up to the same outlet. It is not the cable because the tv's in other rooms are working.

    I have what sounds to be the same exact problem. After only 2 months of owning the the unit, it randomly shut off and will not turn back on. It does have power because the VISIO emblem located at the base of the tv is lit up in its usual orange glow, but the tv refuses to turn on. The only difference is that I have a 42 inch model. Just out of curiosity, is this is a typical problem for the manufacturer, or is there a typical usage issue that causes it? Floating voltages or powere surges maybe?

    Same exact problem as the prior post with a 42 inch plasma. Owned the machine nearly two months to the day, shut it off on a sunday AM, Sunday PM, the unit will not power up. Unit is getting power, as the Vizio name plate is orange, but it will not power up.



    Pretty obvious Vizio has an issue with their power supplies.

    My 42 " vizio has the orange amber light but will not turn on. Just over a year old and has very little hours on it.

    I think our main power board went bad. Please advise. Thank you.

    My 26" Vizio is doing the same thing.

    I found that if I un plug it and wait a minute,then plug it back in and turn it on with the power buton on the TV it will come on. The remote will operate the tv then.Only when it is off for a long period of time do I have a problem,but I think it will only get worse. I have E-mailed Vizio Tech support with this problem. No answer so far.

    I own a Vizio P4 46" Plasma and after one and half years last week end I encountered the same problem with the power source(turned off and does not turn back on, despite the power light indicating green). I contacted Vizio and the out of warranty center and they are slow in responding. Should I contact a local repair person? or is this something I can fix on my own? If so, how difficult would it be and how expensive?

  • austinrp243 Mar 07, 2009

    i did have mine for more than a month and same darn thing happened to it, **** i whent to wal mart and they've got one on the display stand that wont power on either

  • mommacosta Apr 18, 2009

    Just last week I experienced the same problem. My family and I were watching tv when it just turned itself off and will not turn on. Its as if its unplugged. We have tried all the trouble solutions and still no power. So i decided to call the repair center, since its still under warranty, and have had nothing but troubles dealing with the representatives. I have given them all they ask for and still have had no luck. At this point I just want to pay to have it fixed or repair it myself. If anyone knows how please let me know. In the mean time I have a 1200.00 paper weight in my living room.

    I have a vizio VP422. It turned off by itself and won't turn back on. The yellow/orange VIZIO logo is lit up but the TV won't turn on.

  • Anonymous May 19, 2009

    I turned the TV off and when I went to turn it back on a few hours later it wouldn't turn on. The orange light is lit up but nothing works.

This sounds like the main power board went bad. If this is still under warranty, contact 1-877-MYVIZIO and they will have it repaired for you. if not, let me know and I will guide you to the right part.

I want to share this with you guy whose having problem with their Vizion TV. I have the same problem with you my Vizio TV died after two years, called up ITI and HD repair which Vizio recommends they are charging around $275 and NO WAY I WOULD PAY THAT. After reading all the blogs, I guy posted that be replaced the capacitor on the power supply, I opened my TV found out that 2 capacitor were pop-out, I order capacitor at digi-key it cost me around $4 and $1 soldering iron at Dollar store. After removing the bad capacitors, I was surprised the TV is working again for the cost around $5.

TV WILL NOT TURN ON BUT VIZIO LIGHT IS ON


The Service Plan from Walmart is an "extended plan" on top of the manufacture warranty. Your Tv is still under warranty from the manufacture.

50" Vizio Plasma reads "No Signal" on all inputs?


Well, your TV is still under warranty. That's the good part.
The only thing I can recommend without voiding the warranty is leaving the TV unplugged for 30min. That way, the TV can reset itself and hopefully correct the problem.

If that doesn't solve the problem, it's time to use the VIZIO warranty.
Here's contact info if you need it.

After turning on the 42" Vizio, the sound turns off


One week old? did you ever think about taking it back to the store where you bought it?? would be my first choice. unless you want a bunch of crazy answers or taking it to an authorized repair shop and waiting a few months for parts to come in and more time for the repair to take place.

Vizio 50 inch plasma -- remote not working


You can also try to take out the batteries and push all of the buttons with the batteries out of the remote. Then put the batteries back in and push the power button on the remote. If this doesnt work press the two TV buttons at the same time and the remote should be fine.
