    Vizio VX37L. Tv turns on no picture,no sounds.

    Just got a vizio vx37l for $25 off someone off craigslist. Press the power button to turn it on. Front logo lights up. Backlights go out. Shows a white line and then screen goes black. But backlights are still on and tv won't turn off with remote or by power button.

    Check power supply. Got all the right voltages from the power board. Read on here that this vx37L have bad main boards. But I don't whats bad on the board my self. Need help diagnose it. Oh yeah got 5 volts and 12 volts at the main board fuse.

      You need to test those 3-pin Voltage regulators on the main board.
      Please read this post and report the readings in format as requested.

          Vizio E701i-A3 Vizio logo flashing then turns off
          by Super360
          Ok so here's the story. I was watching tv one day when all of a sudden I heard a pop from the back of the tv set and rushed to unplug the set. By this time the tv already had smoke coming out the back. It was not storming or inclement weather that day to cause a power surge to the best of my abilities. When I opened the tv up, I found that the three capacitors on the psu (highlighted in red) were all bulging and looked they had exploded. I replaced all of them right away and when I went to start up the tv after the "fix" it started just showing the flashing vizio logo as soon as power...

          Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
          by Tynan Dill
          I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

          Upon bringing it home and plugging it up, it showed a standby light.

          I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

          The screen seems to blackout and stay black, but with a flashlight I can see the display.

          With my Playstation 4 connected via HDMI, and running a game I can hear sound.

          Vizio M60-C3 powers on, perfect logo, turns off
          by ossroy
          Vizio M60-C3 powers on, perfect logo, turns off. If you don't touch anything it will repeat this process by itself until it is unplugged. Not the "button board" since I disconnected the cables to the main board and the problem persisted. So I'm fairly positive something is going on with the main board, but want to know if there is a fix for this other than replacing the expensive mainboard, which may eventually have the same problem. Also, heat sink was hot as hell when this all started. Unplugged for a few days and same thing happens.

          My kids are getting antsy waiting...

          MacBook Pro 14" M1 Pro Turns on functions then turns off when I plug in USB C cable
          by Stephen
          MacBook Pro 14" M1 Pro Turns on functions then turns off when I plug in USB C cable to reset the computer. I disconnect the battery fully and then reconnect it and it won't turn back on. After letting it sit for a day I plug the battery back up, and the MagSafe 3 cable and it powers on and stays ons, once I plug in a USB C cable into the port closes to the MagSafe port it turns off and the Amber light turns off and won't turn on. No water damage, nothing, I want to do a DFU restore to wipe the computer since the customer stated they did an update and ever since it just decided to not work...
