    Vizio TV won't turn on

    I'm having a problem with my VIZIO SV422XVT 42-Inch Series 240Hz TV.
    Whenever it is unplugged or looses power it won't turn back on. The Vizio logo flashes orange/white and the power button is unresponceive. There are no visable problems on either side of the boards or any swollen caps.
    I've tried the power button reset which worked once but never again. I continued trying to turn it on periodically by unpluging and replugging and that too worked a couple times. I have replaced the power board on a guess. That didn't help but for some reason I was able to turn the TV on about three days later. So my question is by what kind of magic does this TV operate? I can't figure out what allows it to finally turn on.

    I bought a UPS for it so if I can get it to come on once more I will hopefully never have the problem again.

      VIZIO M65-C1 Does Not Turn On
      by Mulp
      Hi All,

      I am having an issue with my Vizio M65-C1 where it does not turn on. When I plug it in the stand by light on bottom left of screen turns on (white) then fades away. If I press the power button it turn back on and then fades until it is super dim.

      When I remove cover, there are no illuminated leds on the main board, I've seen others with a red/blue led that turns on.

      I've done some research and what is interesting is my voltages all seem slightly different from other people. For example +5/3.5v is 3.48V when on which is different from others on here....

      MSI GF63 THIN 11UCX (MS-16R6) LAPTOP WON'T TURN ON AFTER RESTARTING
      by RdeveLabs
      To all the members here...

      Let me tell you a little bit about what happened to my laptop (MSI GF63 THIN 11UCX model: MS-16R6) that “maybe” you know how to solve this problem.

      So before this problem happened, my laptop was running smoothly. When I wanted to restart my laptop, it looked fine at first. But after I waited for this restart process to take a long time, until finally I panicked (because the restart process did not finish plus the laptop screen only showed a black screen), I immediately pressed and held the power button to force the laptop to turn off. But...

      Acer Aspire 4520 won't turn on after reboot
      by robante15
      Hello, I have an Acer Aspire 4520 from a couple of decades ago and I want to repair it solely for nostalgia.

      It happens that when I turn it on after having been disconnected for a long time, it turns on without problems, it tells me that the BIOS has been reset and that it will load the factory settings, if I tell it to continue, the computer turns on and everything works fine.

      The moment I turn it off and want to turn it back on a second time, or restart it and try to start it again, it no longer gives an image, and it no longer responds.

      If I remove the...
