    What to do? Got new board.....

    I ordered a new main board for the Vizio I'm working on and one connection is different on it. Can I simply remove the connector on my old board and solder it to the working board? If so would I need to remove the other connector from the working board or can I just leave it on there? I'll post pic to show what I'm talking about....





    Thanks for the help!

      Is that connector for a subwoofer in the back of the TV? If so, you probably can't put it in, because there are some other missing parts which would drive that subwoofer.

          No sir... It connects to the power supply. It's the left connector in the pic.

              Might be additional power for audio amplifier - without it - amplifier may not work or it may not be as loud.

              Your photos are too small to make much out on.

                  I can do better pics if need be. I just had my phone on me at the time. So it's ok to go ahead and hook it all up and try it out without that one connection?

                      Got everything together and all works like it should, sound, pic. The only thing that doesn't work is the wireless card. So would that one connection have anything to do with the wireless?

                          Do both boards have a WiFi module?

                              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....

                              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

                              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...

                              TCL 55S425 few horizontal lines, potential failure on both side of panel/buffer board

                              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
