When turning the tv, the logo comes on. Then shortly afterward, the unit turns itself off. I have seen post about this same problem that suggest it may be a power supply regulator ic chip. Does anyone know the part number of the chip?
My Vizio E322AR White Vizio Light comes on when plugged in, then slowly fades to "Off". I unplugged and replugged - same. I held down the power botton on the side, and plugged in... same. Vizio light comes on (White) and over 5 seconds or so... fades out to nothing.
Remote doesn't do anything, buttons on the side don't do anything.
Going to pull the back off and look for bad Capacitors, and test fuzes for continuity. Wish me luck ... will report back later with results.
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.

This is the only place I founf that carries the

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.
SOURCE: Vizio E550VL won't turn on. The vizio logo just flashes orange.
Good day!!!!
That problem is usually cause of faulty capacitors on the power supply board..
Just follow this instruction to fix your TV..
1. Open the back cover of your TV.
2. Look at the power supply board..Its normally connected to the power cord..
3. After that,,try to look at the actual image of capacitors if it is bulged on the top so that you can easily determine the bad capacitors..
4. After that,,try to replaced the bad capacitors using soldering iron and soldering lead..replaced the capacitors only with the same type ratings and value..
5. Some of the capacitors not bulged so its better if have a capacitance meter
