    Vizio TV Model e321VL stuck on Vizio logo screen

    Hello! After the disappointment of my TV not working I researched on the internet and learned that particular model was prone to the stuck on the VIZIO logo problem.

    I tried factory resetting it but it didn't work, so I took the back off and took pictures for you guys. I know nothing of TV's, so I can't identify a loose/bad connection just by looking at it. I'm so willing to put in the effort of fixing this, I just don't know where to start.

    I know that there's already a lot out there on VIZIO TVs with similar problems but I can't use those resources without first identifying the main problem. That's where I'm hoping you lot can help.

    I'm not sure if this is relevant or not but I first encountered the problem 3 weeks ago. It was the week I was leaving my college for winter break so instead of trying to fix it I unplugged it and left for home. When I came back from break I plugged it back in and it turned on! I was so happy. It worked for two days, and then I plugged my computer in using an HDMI cord, used the TV and unplugged the cord. Later that night it didn't turn on :'(. When it stopped working the first time it was right after I unplugged my computer from the TV via HDMI again.

    It could have nothing to do with the main problem but I don't believe in coincidences. At the same time I feel like HDMI can't break a TV like that.

    Anyways, any advice you guys can offer will be worth a million! Thanks in advance.

    Here are the pictures I took, hopefully they are clear enough:

    I'm a newb when it comes to TV repair myself so wait for the more experienced folks to give you advice, but after doing a brief google search it appears the problem could be a bad eeprom.

    If the eeprom needs to be replaced it would require soldering. If you don't feel comfortable doing the soldering yourself I saw a repair service on ebay that's $45 or you could buy a replacement main board for around $50 (used on ebay) or $70-$85ish new @ shopjimmy.com).

    Again I could be wrong so don't do anything until you get more replies from the more knowledgeable folks here. I was just bored and figured I would research it a bit for you.

    good luck

          voltage regulator are the three legged devices and yoy need to see what the voltage is on each end of the fuse have you got a multi meter? if you have and not sur what setting to put the meter on post a picture up and we can advise you is your main board exactly the same as the one in the picture?

            Yes the pictures are from my TV, I'll post closer pics whenever I get the readings. I have to go out and buy one, thanks for your help. Do I need a voltage regulator and a multimeter or just one of those two? I don't want to spend any more than I have to.

              Check all voltage regulators. 3 pin ones on the mainboard. Ones probably out of spec. U18 possibly. On the power supply probe the ps_on pin and press power on button. Do you get 3 when pressing the button?
              Did I leave the soldering iron on?

                a multi meter for a start the rest you can order on line if needed/want to.

                  I haven't bought a multimeter yet to check, it'll probably be a couple days but as soon as I get those number's I'll let you know.
