    Vizio vx20l - no picture no sound powers on, cannot turn off

    I've seen similar type posts for similar issues/models, but not sure if all the recommendations would apply. I've checked out the main fuses and the regulators and they all seem to be ok. Any other tips or next things I should check?

    Thanks in advance and much appreciated

    Check caps maybe... post pictures so we can inform you better what to check. I would say to check the inverter board but your tv might not have one. From the pictures...oh...wait... there are none.

            For each regulator list all three pins (the fourth tab pin is the same as the second pin) plus the part # on the device.
            Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!
            For service manual, schematic, boardview (board view), datasheet, cad - use our search.

              Vizio M65-E0 No Picture, No Sound
              by ggil44
              Hi I inherited a Vizio M65-E0 that isn't working. It must have been dropped on the corner because I found that the infrared circuit had a capacitor with one end broken off of the board and some green corrosion around the plug to the main board. I re-soldered the capacitor and cleaned the corrosion well and tried turning the M65-E0 on and I was successful. My problem is that while the back lights come on and appear to perform local dimming there is no picture or sound. It kind of looks like you are looking at the TV through a very dense fog, where changing the input on the remote will change bright...

              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...

              Samsung TV model UE50TU: rebooting, backlight, sound, but no picture
              by TR103
              Hi, I have a Samsung UE50TU with:
              - sound and backlight, but no picture
              - when it arrived, it had a picture for a few seconds
              - it keeps rebooting
              - without ribbon cable between the two panel boards, it does not reboot but I have no picture
              - without cable between mainboard and lcd panel, it does not reboot (but obviously i have no picture)
              - when i try a tape fix, its keeps rebooting, unless I tape off pin 1 (the innermost pin). In that case it does not reboot but I have no picture.

              - without cable between mainboard and lcd panel and with a jumpered...

              Samsung UN60EH6000F Black Screen, Backlight and Sound Good. Power Cycle Returns Picture
              by Mgiffune
              I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started β€˜fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.

              I ordered a supposedly β€˜new' Tcon board this time, and
              ...
