Question about Vizio L32 32 in. LCD HDTV
Same problems as several other consumers. A few weeks ago my Vizio L32 started turning off on its own several times throughout the day. I would have to turn it on again. After being gone on vacation the tv will not come on at all the yellow lcd light is on. I have tried unplugging from unit and wall and waiting, not luck. TV is only 2 years old I think a tv should last longer than that in this day and age. I believe this should be a recall item by the company since alot of consumers are having the same problem.
I used the LG code 0178, to program my universal remote, it was not a One For All remote but the code worked.
I can't remember where I found the code, but give it a try!

SOURCE: TV WILL NOT COME ON
hello, if it's shutting down and giving you trouble or staying on when you press the button, your set needs service. unfortunatly there isnt much you can claim if your waranty expires. there are different types of shutdowns caused by voltage spikes or drops. these sets operate at high heat and high voltages the parts go bad they loose there resistance and dont hold the proper specified loads they go haywire or dont turn on at all. so this is how they go bad even with short term use. you may want have it service. if the issue is constantly interupting your tv viewing if your set is not coming on at all. it is common with these newer lcd & plasma tv's. your fix is sort of simple a matter of exchanging or repairing a board or two. some of these fall of the stand and break instanly, i have heard of kids trowing wii's trough the screen glass. your tv is still worth its value if your main panel is good this is what the tv is built around. so if you have a circut issue maybe a button or panel that is fualty get it estimated and serviced.
hope this helps

Most likely the TV has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
But, I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists. Usually, cost under $20. And most cases the new part cost less than $15.
I hope I shed some light on the subject for you.

The issue you describe is consistent with a power supply board issue. This is the board where the AC goes to. This problem may have occurred as a result of irregular power supply, or excess power supply or power surge.
The TV is receiving current but cannot circulate or transfer the current to other necessary part of the TV because of the defective power supply board. You might be lucky it's just a blow fuse. Also a defective transformer can cause your TV not to power on.
All these can be checked on the power supply board.
But more often bad capacitors causes problem on the power supply board. I do not think the power board needs replacement, rather those defective capacitors is causing this issue. Open unit up and take a look at the power supply board.You will probably see one or more electrolytic filter capacitors that are bulged up in the top-not perfectly flat like the others.
The value of these capacitors will be different, most likely they will be somewhere around-820 to 2200uF/25 V( or /10V sometimes)
You can replace them with same values but I would recommend the voltage rating to be higher(like 35V for an original 25V) for reliability purposes.
What happens is,these bulged top capacitors will cause a low and unfiltered DC voltage=main board will malfunction(the relay will keep clicking until the caps are holding enough charge to bring the voltage up over a threshold point).
You can buy these capacitors at any Fry's or Radioshack store or you can order them online at vendors like "mcmelectronics.com"(look for electrolytic capacitors). After replacing these capacitor(capacitors) most likely the normal operation will be restored. Or you can by a refurbished complete power board to save you some stress.
Note: There may be also some other causes for this symptom ,like a defective T con board ,or main board,but the bulged top capacitors are the most common cause for this issue.
If you don't know about TV repairers, take the TV to the nearest repairman to fix the fault for you. Also, note that TV stores a lot of current, so wait a while before opening the TV back cover.
I hope this helps.

Tips for a great answer:
you'll need to do a master reset of the device
