    Vizio P50HDTV10A Image problem

    I have a Vizio P50HDTV10A with this image displayed on the screen. Before this happened it would put a horizontal ghost image down one inch to three or four inches briefly when an image had a bright background over a darker one. Now it just has that image.

    Thanks,

    Kenneth

      One of them or both?

        Would it be one of the Y buffer boards or both and is there any test to check?

        Thanks,

          Moved from troubleshooting guide. This problem deserves a thread of its own.

            Should I try one at a time?

              There are methods on the internt which describe how to test buffer boards

                Common fault is a blown FQB46N16 FET on one of the buffers.

                Ysus may be on its way out as well. I did a similar repair on the buffer and the tv came back to life but only lasted a couple hours before the same FET blew again... I replaced it again and put a heatsink on top of it, but this time the TV started showing signs of flicking picture (symptoms of a bad Ysus)

                  Vizio V585-J01 dancing lines and image doubling
                  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...

                  Vizio E500i-A1 Monochrome (black & white) image
                  by NSkyLab
                  Hello, I have a very weird issue with my Vizio E500i-A1. It works well except it only shows monochrome (black & white) image. TV signal is b&w, all HDMI inputs are b&w. At the same time the TV menu is colorful. Of course I tried to change color/saturation settings, it doesn't have any effect.
                  I tried to do factory reset. The TV setup screen was colorful, however it didn't help, all inputs are still showing b&w picture.
                  Checked voltatges on MB and all seem to be fine.
                  UPDATE: tried to play an .avi file via a built-in media player. The media player menus are colorful,...

                  Thinkpad X1 Carbon "LMQ-1MB 12298-2 48.4LY26.021" VCC3M problem
                  by Zeonalbasta
                  i have a problem with thinkpad X1 carbon gen 2 "LMQ-1MB 12298-2 48.4LY26.021"
                  The laptop was turned off because the MOSFET was not transmitting voltage. After checking it turned out that the gate pin on the MOSFET was the problem, because it was producing an inappropriate voltage. and it was discovered that the problem was with the Think engine, so I decided to reprint each pin, and finally the mosfet could work properly. However, there is another problem, even though the voltage has been supplied to the laptop, it still won't turn on, there isn't even an LED indicator. After double...
