    Vizio M470NV input (remote) problem.

    I've got a M470NV I just replaced the main logic board on.
    It now boots to the setup screen, and wants me to go thru the setup menu, but it's not responding to the remote keys.

    The remote I have is the double sided model XRD2BR.

    The volume keys work on the remote, and the osd changes the volume, but that's all I can get it to do.

    I'm not getting anything from the jogwheel when trying to change the menu selection from home use /demo.

    Thanks for looking.

    Later,

      Have you checked or replaced the batteries? Is the cable from the IR remote sensor cable pluggerd back into the main board? Is the sensor circuit board in its orginal place and the sensor is not blocked? Does the led on front of the tv blink when operating the reomte?

          Batteries are fine, as I said the volume controls work fine, I'm wondering if this main board needs a different remote than the original.

              That can be the possibility. By the way, the new board has the same PCBA numbers as printed on the barcode sticker?

                  The guy I got the tv from gave my what he thought was the remote, but it turns out its the remote for a smart bluray player.
                  (It has the app buttons, and the qwerty keypad on the back)

                  Looks nearly identical, I just didn't examine the part number close enough.

                  Grabbed a universal remote, and the tv worked fine.

                      Vizio D65x-G4 Volume changes on its own
                      by karthur
                      On this Vizio D65x, the volume will change on its own. I don't mean like during commercials where the volume will increase. I mean its like the (+) volume button on the remote is pressed and the actual volume dialog is displayed on the screen going up. It will do this, then the volume may start going down. It might go all the way to "0"or it might stop at a different number, then start going back up. The whole time its doing this, the volume dialog is shown on the screen.

                      It wont do it until it has been "ON" for 20 or 30 minutes, so it does seem to be heat related....

                      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 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...

                      Vizio E55-DO firmware corrupted?
                      by Lee M.
                      I was given this set and do not have the original remote. It will turn on with the power button and display "oobe V1.1.12 firmware V0" but that's all it will do. It does not respond to the input select button or volume button. I have a remote from the cable company and programmed it for Vizio and it will turn the set on and off but that's it, no response from any other buttons. The white standby led comes on bright at first and then dims but stays on while the set is on. I pulled the back off and looked for anything obvious like loose connectors, bad solder, bad caps and didn't find...

                      DeLonghi AC Remote only accepts 3V
                      by cstout
                      Hello all, I've been looking into this portable air conditioner's remote control and can't find what could be causing the problem - or possibly this remote is just terribly designed.

                      The remote only works at exactly 3V - if I drop it any lower, using my bench power supply, to say, 2.9V then the remote will not flash the display and turn off. I don't have any AAA batteries that are exactly 1.5V each so I'm not sure if this remote is designed this way - to only use the freshest possible batteries, or if there's a failed component in the mix.

                      I can't find any schematics...
