    My Vizio tv will spontaneosly turn off. At first I thought it was a remote frequency problem (neighbor in area on same frequency) but I have moved and the problem continues. Any suggestions?

    I'm having the same problem. I turn it on and it turns off in a matter of seconds.

    I have the same problem...but it turns off a few minutes later. I turn it back on, and it does it again. I tried cleaning it out. I tried using a fan in the back, thinking it was over heating and it hasn't changed. In fact, it has progressively gotten worse; by that I mean, it turns off sooner and sooner. Very annoying. My TV is about 3 years old and is the 42".

    We are having the same exact problem. Today I turned it on and I can only see a blue screen & at the top it says NO SIGNAL. Then the TV (GV42L) turns itself off. I have had the TV just under 3 years. It has been doing this for several months. Today is the first day that I got the blue screen.

Just hold down the input button on the right side of the tv. This is the bottom one. So,
With the tv off,
press and hold the bottom button (input)
when the tv turns on, and you see the input menu
release and press the button to put the tv into a mode that works!
Thanks

SOURCE: My Vizio 37' flat Screen TV Closed Caption wont turn off

If you have a digital cable box, turn off the box but leave the TV on. Hit the "Menu" button on the front of your cable box and a setup menu should come on. Use the cursor buttons on your box's front panel to go down to the "Captions" option, which is probably set to "Enabled" and hit the right or left cursor button to change it to "Disabled." That should solve your problem.

SOURCE: New 32 in flat screen Vizio tv will not turn on no

I had the same tv, same problem. take the back cover off and look for the 250v ceramic fuse (looks like a glass tube type, but is porcelin) For ease of replacement and a cost of about $00.80. I would start there. If that does not take care of it, than you can move on to the other options.

Assuming the Vizio name is the powerlight, then this is your problem and solution........................The caps (capacitors) in the powerboard are going out. This is a very common problem in all class and price ranges of modern lcd and plasma tv's/ monitor's. I don't know if this problem has been like this for awhile or it just started, but either way, if the tv takes an abnormal amount of time to "warm" up then it most likely will go out all the way sometime in the (near) future. If you have a tiny bit of will and knowledge ypou can open the unit and get to the print board. Examine this for "popped" capacitors, they will have a buldging top instead of a flat one. Im gonna try to include a pic of them here, if i can get it this time, I've tried bfore lol. But you can google image a "popped" or "bad" capacitor and you would be able, with ease, to diagnose if you have any of these. Usually only one or two. Radioshack sells capacitors (couple anyway) for $1.59 each. MAKE SURE the replacement is of the SAME voltage or HIGHER, or you will be right back replacing those 2. Every capacitor has a negative pole marked with an (-) on the side of the capacitor(by one of the "legs", always puit the negative (-) "leg" of the new capacitor in the same hole in the printboard as where the previous negative (-) "leg" of the capacitor was ( a capacitor with the negative and positive "legs" put in backwards will result in the new piece "popping" as sson as you turn it on!!) make sure the "uf" rating (for example the most common popped capacitor is the 1000 uf) is the same as the one you are replacing. I needed 1000 uf, 105 c and 26v (volt) ratings for the 1 capacitor I needed to replace to fix my LG 19" lcd panel monitor I found by the trash that the light came on off, but it didn't come on. I replaced that capacitor with ; 1000uf, 85 c and 36 v (volts0...It works fine eventhough the volts and the temperature rating (36v and 85c) was not the same as the (26v(volt) and 105c ) capacitor I removed !! Further, I've replaced capacitors that had the celcius rating of 105 with the only ones Radioshack had, namely 85 c(celsius) they have been working great, but I'm not sure about any effect, nor have I heard or read (yet?) about that making an urgent difference. Many threads that I've read people have done the same, so we should be ok (my stuff has been running good for a while longer then most brand new ones!.............(all these ratings ; 'uf ' and 'c' etc are on the side of the capacitor you are replacing and on the side of the ones you are replacing them with)...For all this all you need is the cheapest solder gun u can find (I bought one for $7.99 at Radioshack), a camera (to take pictures as you go to remember how to reassemble the unit) and, once you have your materials, 20 minutes to replace 2 or 3 capacitors and you are good to go...Most monitors and tvs (lcd/plasma) I've seen you have to lay flat on the ground/bed/blanket etc, to work on (screen side down). Usually there are 2 or 3 screws (or a few more) to remove, then you will have to carefully (its comes off easily most times)insert a flat screwdriver inbetween the casing and gently pry it up as you go around the whole frame. Sometimes you have to remove the little washer arouind the cable input orso, just be gentle and you cant go wrong. Once insidet here will be a box with wires running to the sides etc...unplug, gently, these wires and open the box. Inside you will find 2 or 3 circuitboards, check them all for "popped" capacitors, replace, reassemble and plug it in....Have fun becoming an overnight tv mechanic lol!

If this has helped you (or not), please rate, thank you

SOURCE: my vizio flat screen tv

You have faulty electrolytic caps in the power supply section of the tv. Capacitors with reduced quantities of electrolyte take longer to charge compared to normal ones. That is the reason its coming on after you repeat the on/off sequence a few times. If you are not good at soldering, replacing the power supply should do the job. It should cost you about 75-100$. Let me know if you want to do it yourself(please get me the model number of the set as well so that I can find you a replacement).

it had no cord because it was no good

Need code for my vizio tv i bought a ihip remote control for my tv


The instructions on letting the Hipi remote to seach for the code that came with my remote are not correct. I used the instructions from HOWTO.COM and printed below. There are two changes from the printed instructions. The first is to push the <TV> button after the <Code Search> button. The second is that the <Enter> button saved the code not the <MUTE> button.

Instructions
1
Turn on the Vizio TV.
2
Aim the Jumbo Universal Remote at the Vizio TV and hold down the "Code Search" button on the remove for roughly 3 to 5 seconds. The LED lights on the Jumbo Universal Remote will come on.
3
Press the "TV" button at the top of the Jumbo Universal Remote.
4
Start pressing the "ON/OFF" button repeatedly until the Vizio TV turns off. (This took only a few tries for my Vizio TV)
5
Press "Enter" on the remote immediately after the Vizio TV turns off to save the code.
6
Test the Jumbo Universal Remote by trying to control the Vizio TV with the remote. If the control doesn't work with the remote, repeat the entire process.

My 42" Vizio LCD Tv Turns on/ wont turn off or display picture.


If you haven't tried it yet, pull the AC plug and let it sit overnight. Your set and most later ones do have microprocessors in them that can have 'lockup' problems similar to a resonal computer crashing.
If it still isn't responding to set-mounted or remote controls, you may have hada power supply failure.

42 in lcd vizio "no signal"


if the TV have a no signal sign which means most of the important part is missing. Try checking your connections. The best way is to hook up a dvd player using AV input (the yellow, red and white). make sure that you turn the device on and whatever input you connected the device to is selected. if your TV is a P50HDM model, the TV will shut itself off after a short period without and input connected.
