John Doe: Hi Tampatec, i've got the 3647-0072-0150 main board, the exact TV in this video. On the main board I'm missing 4v on the inverter on pin 13, the power supply to main board cable. Before i picked up the TV the person before me put in a new power supply from shopjimmy and a "good" master inverter from ebay. Where do you think i should start looking? I have 3v on pin 12. I tested the power supply, i've got 24v on inverter supply, and all 5v standby.
Monae Artistry's Hair and Makeup Blog: Where is the part 2 of this video where you fix it?
Brian Hinson: Hi, I have a Vizio M550nv HDTV that I was given. The original symptom was, once it was plugged in, the logo would flash amber/white but the screen would not come on. I found a video that instructed me to do a “pc cold boot/hard reset” by unplugging the unit, holding the power button in for 30 sec, plug it back up, and after the logo stops flashing amber/white, see if it would power on.
It DID power on and worked just fine for about a week. [it did power off a couple of times but I was able to repeat the above procedure at restore power] Now the amber light will come on but that is all. I cannot get the screen to power on no matter what I do. I replaced the power psu board per suggested by several videos I watched but the symptom was unchanged at all. [$68 mistake] I have visually inspected all components for burned, bulging or damages parts but all looks good.What Is your opinion?
Bryan Slagle: have backlights and replaced all boards.replaced econ once and then went out
koloasurf2012: Video is out of focus and too much moving around but the video is informative just annoying to watch with all the moving around.
Raymon Artopee: I checked and the vizio does illuminate orange when plugged in but does not illuminate white when power button is manually depressed on with remote.
Trainwreck4207: i have a p series 50 inch and it wont turn on. doesnt even click. please help
Street Guru: Mine looks perfectly fine, least to my eyes, the cord works for sure on it and there's no visible damage aside from the little burn that I did that was localized and doesn't touch anything. I wonder if it's as simple as a power on button malfunction at this point.
seaboyblue: Hello Tampatec. I have a question for you aboutmy Vizio TV. Can I get your email address please?
showtime1285: Mine just recently would not turn on one day so I unplugd it then powered on with remote n it worked fine but every day or few days I have to do the same thing n think I'm causing long term damage by unplugging n plugging back in all the time:/ any way to fix this problem or what causes it?
TheNo1Studda: I have a Vizio VW42L FHDTV10A and there are no blown capacitors anywhere and the tv will not turn on or off and the Vizio does not like up amber.
observer17: Great video, very informative.
Gonzalo Martinez: I replaced both my boards for my vizio e420vl n now it turns on but flashs white for a second n goes bad to black empty screen. I need help

Adrianne Barcenas: E47OVL I have a vizio. I was watching it then all of a sudden it turns off. It still gets power bc the word vizio is orange but it won't turn on. The vizio light won't even turn white indicating that it's on. I was told it might b the power board. What's your opinion? And how much would it cost to get it fixed?
Versa Slappers: where do you buy this stuff like the power supply etc?
Raziel Cain: I have the same board and scorching on my power supply board, I ordered a new power supply and it still did not fix the problem. On the slave and master I had four more blown capacitors. I replaced the caps as well and still there is no power to the backlight. Looking for your next video. Thanks.
ShellacSoup: Vizio is awful
James Caballero: Tampa, i have one doubt my VIZIO M470NV powers on, light blinks amber/white then goes solid white and the V appears on the screen, but after a few minutes goes off and does the same blinking thing and repeats. For what I been seeing I believe is the POWER SUPPLY BOARD? any thoughts? as oppose to your video the tv goes un step further (the logo appears on screen) so is still a board issue? thanks hope you can help me.
