Question about Vizio L32 32 in. LCD HDTV
Immediately after turning tive on, it turns off seconds later
SOURCE: 42 inch LCD Vizio. "no signal"
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!

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.

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

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).
