Vizio E502AR turn power on in AM the vizio logo comes on and then it shuts itself off. FYI- last night we had an update come in when we first turned it on..help it is maybe just a year old. We did try unplugging it, we also tried the hard rest.

Old messages and bcipollina is gonna get to read this resonse twice; sorry-
If it just fails to turn on or ignores the remote, the
main power supply is probably at
fault and without some technical background and a couple of test instruments,
you will not be able to do the repair yourself.
What you can do though is; unplug the set, let it
stand overnight or at least several hours, remove the back panel and look for a
separate board with mostly larger components on it; it will have a ferrite core
transformer on it and several larger capacitors which are cylindrical and
mounted vertically to the board.
Before touching anything inside,
especially on that board, allow several hours to be safe since the larger
capacitors can hold a painful voltage charge for some hours.
If you see signs of overheating
such as discoloration of the board material, it may not be repairable but if
you can find a part number on the board, you might be able to buy the power
supply and install it yourself.
If there are no signs of heat
damage to the board, there may be companies offering to repair it as a
subassembly instead of repairing the whole set which could be much more
expensive.
If you choose to replace or have it done, the power supply still may not be at fault since most
are capable of switching on and off if a downstream problem is causing an
overload.
BTW, from what I have read about Vizio, I think they are close relatives to iLo which was also sold by Wal-Mart.
Quality control anyone?
SOURCE: only vizio light come on then nothing. have to unplug to turn off
there a problem on power side.. chage the ic and the resistor going to ic and check also the signal diode.
SOURCE: vizio 47" lcd no picture no sound has power
this could be one of two problem. first, check if you have back light. If you do then the problem is with the M/B. Second, if you don't have back light then the inverter is bad and needs to be replace.
SOURCE: no picture or sound, light comes on in the front and have to unplug tv to turn it off.
I had this exact problem on my Vizio 47" HDTV. I removed the speakers and all the screws on the back cover. Took the cover off and located the fuses on the largest circuit board. The are in the upper right hand corner of the board. There are 3 of them in a row labeled LF 1.5, LF 3.0 and LF 3.0. The are white in color with copper ends. I took a volt meter and measured continuity across all fuses individually and found the LF 1.5 to be blown. The guy at the electronics store sold me a barrel 1.5A fuse and told me to soldier it across the top of the blown fuse. It took an extra set of hands but the TV works perfectly.

For the cheap guy like me who will probably do more harm than good:
Also check for the F3 Fuse on that same main input board. It is located in the upper right corner. Hard wired fuses; very small. You will see F1-F4 (F4 is empty). You can solder a replacement fuse right over it. I would recommend piggybacking the fuse with a fuse you can replace. Will need the holder and a new fuse. 6 bucks.
Doesn't solve problem, but I can go another 2 1/2 years and the wife won't blame me for screwing up the TV in the first place.
