    Vizio 42" Plasma - P42HDTV10A - Turns on but can't change input

    So I picked up a dead Vizio, changed out the caps on the power supply and got it working, but now i can't change any of the inputs/menu/channels either from the remote or the side controls.

    Thoughts as to which board is bad?

    Re-seated the connector to the button board? Or, it could be a stuck button on the button board causing the TV to ignore remote control input.

      Does it switch on and off from the remote?

        No it does not...

        Leaning towards replacing the logic board.

          I would try the switch board first, just in case, it is usually cheaper too.

            Tuner board?

              No, the board with the buttons on it. Is it separate?

                No, they are separate. I'm going to try and detaching it and seeing if the remote works then to see if it's that board that's bad.

                  820-02020 Super Weird Issue: Keyboard Input Character Map "Wrong"?
                  by ugamazing
                  So, I have a really bizarre issue that I'm struggling to identify the cause of. Working on an 820-02020 board with some bizarre keyboard/input-source character mapping. My suspicion is a possible damaged SPI ROM (U1970), perhaps, but I'm really not sure in this case:

                  1. The issue is pretty weird, but when installing MacOS, I noticed my WiFi password did not work. I quickly realized the special characters (!@#$%^& etc) were not mapping correctly.

                  2. I noticed the keyboard layout/input-source is defaulting to JAPANESE every single time I restore the board. I am not...

                  Vizio E701i-A3 Vizio logo flashing then turns off
                  by Super360
                  Ok so here's the story. I was watching tv one day when all of a sudden I heard a pop from the back of the tv set and rushed to unplug the set. By this time the tv already had smoke coming out the back. It was not storming or inclement weather that day to cause a power surge to the best of my abilities. When I opened the tv up, I found that the three capacitors on the psu (highlighted in red) were all bulging and looked they had exploded. I replaced all of them right away and when I went to start up the tv after the "fix" it started just showing the flashing vizio logo as soon as power...

                  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.

                  Vizio M60-C3 powers on, perfect logo, turns off
                  by ossroy
                  Vizio M60-C3 powers on, perfect logo, turns off. If you don't touch anything it will repeat this process by itself until it is unplugged. Not the "button board" since I disconnected the cables to the main board and the problem persisted. So I'm fairly positive something is going on with the main board, but want to know if there is a fix for this other than replacing the expensive mainboard, which may eventually have the same problem. Also, heat sink was hot as hell when this all started. Unplugged for a few days and same thing happens.
