    Vizio VW26L HDTV10F Lines on screen and shuts off randomly

    I have a Vizio VW26L HDTV10F that has stopped working recently. It powers on, but the picture is weird, and then it fades into the normal blue screen. If I leave it sitting there, sometimes it will power itself off after a few minutes. I took the back off and didn't see anything out of the ordinary, so I thought I would ask for some advice. Would you think the Main Board, or the Power Supply would be the fault?

      Perhaps that is a "no signal" screen and it is powering off after a few minutes -- may be normal behaviour?

      In which case try attaching a source and see if that shows distortion too, also can you try accessing the menu and see what it looks like.

          After I let it sit there for a while it finally clears up, and says no signal, but in the pics, is what it looks like when I first turn it on. I can't access the menu, or input either, until it warms up. It doesn't always shut off, but it does occasionally.

              Get a hairdryer, turn the TV on and make sure it is malfunctioning, then heat up that large processor and heatsink in the middle of the board. If functionality comes back quickly, repeat the test a few times to confirm. You will likely discover the processor needs a reflow or you need to replace the main board.

                  Okay, I'll try that, and get back to you soon. Thanks!

                      Vizio E70-E3 Two white vertical lines
                      by brad2157
                      I picked up a Vizio E70-E3 for free that shows Vizio logo and then goes to a black screen. Original owner said he started having wifi issues and then he tried to reset the TV and that's when it wouldn't boot up any longer after his reset attempt. I picked up a replacement main board from eBay that matches the same model # board as the original from the TV.

                      Original main board - Shows Vizio logo when TV powers on, then goes to black screen. Doesn't boot up. No screen issues with any lines on start up Vizio logo.

                      Replacement main board - Boots up fine, but starting...

                      TCL 55S425 few horizontal lines, potential failure on both side of panel/buffer board
                      by howardc64
                      All left and right refers to looking from rear of TV (or looking from front with TV upside down)
                      • TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
                      • Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault

                      by x_orange90_x
                      I got this tv yesterday and it shows a screen full of colored vertical bars and horizontal lines that move, change, and dance around. When the set is powered on there is a slight buzz from the tcon. I removed one ribbon at a time and this was the result:

                      Right side connected, left side disconnected = half image on right (somewhat distorted, see photo attached) white screen on left. NO buzzing from TCON

                      Left side connected, right side disconnected = right side black, left side white with distorted horizontal lines near top of screen. Buzzing from TCON

                      I swapped...

                      by viking509
                      I recently replaced the led backlights with LB65041 LED Backlight Strips and after putting it back together the backlights work but there are only colored vertical lines only in the center of the tv. I can see the Netflix logo (jumbled) after a minute or less the screen went dark. When I turned it on again the lines were back. Then I replaced the t-con board but the same vertical lines in the picture. My question is what is my next step? Could it be a source tab bond issue? A buffer board issue? Could I have loosened a connection to the panel when replacing the backlights? Should I replace the...

                      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.

                      Assuming...
