    Please Help with Vizio M420NV Problems

    I've replaced both the main board and the power supply board. The logo now goes from amber to white when powered on and I see the LED backlights flash on when powered on via the remote.

    But I get no video or anything visible on the screen.

    The main board appears to be a new one and I obtained it on Ebay. Is there anything I'm missing here?

    There is a small power button board that has a jag wheel.. but I'm hard pressed to say that is failing.

          Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
          Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...

          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.

          Problem

          This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....

          LG OLED77G1PUA - No Video / Audio after a TCON Board change and Software Update
          by Hakuu
          Hi There,

          This TV was auto switching off after few seconds with some vertical lines on the screen, so got a new TCON board and replaced it.

          After replacing the TCON board it was working fine and i set it up with everything, used for few hours, then had the bright idea to update the software on it. During the update process, TV switched off and now no audio or video. No relay switch sound.

          problems with LG OLED 55EC930V, t-con board LC550LUD-LGP1
          by randaz81
          I have an LG OLED 55EC930V.
          The problem started a couple of days ago: tv working, but no video, only audio.

          I opened the tv and I checked the parts. The mainboard has the red led on, which means that it working correctly. The power board supplies 24V correctly.

          I focused my attention on the t-con board, LC550LUD-LGP1, I disconnected it to observe it carefully, no signs of damage. Then I mounted it again and I reconnected to the tv.

          After this, the tv started to show a different behavior: it turns on and then, after few seconds, it turns off....
