    e470vl

    I have a Vizio e470vl that is not accepting any input on the 3 HDMI ports.
    I figured this points to a bad chip.
    I have had no luck locating the service manual to do testing.
    Anyone have any ideas?

      Are they available to select in the menu?
      Willing to help but I'm no expert.

              Even if you find a service manual it likely won't help, The few I have do not have schematics and you would likely need a scope to trace the data lines. look at what ic is used for hdmi, find the pdf and go from there.

                      Yes, locate the hdmi ic, then try and find a data sheet for it, or post good clear pictures of both sides of the board, maybe it is similar to another brands main board.
                      Also vizio is prone to eeprom problems so it could be corrupt data causing the issue

                          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 E470VL got +5VSB, but no 12V
                          by Bugman1400
                          EDITED: I thought my Vizio E470VL has +5VSB and no 12v on the PS board, but after plugging the cable back in and testing the pins on the Main board I realized that I do have 12V. I assume the 12V is turned on when the ON/OFF switch is pressed. The Vizio light in front does go from Standby Orange to White when ON. But, I still have no picture or sound. Test values of PS board are below.

                          +5VSB= +5.09
                          12V= +12.18
                          PS_ON= +2.25
                          I_ON/OFF= +3.27
                          LAMP= +3.18
                          DIM= +2.97

                          Any more testing I can do on Main board or is it just a replacement?...

                          Hi.

                          picked up another TV. This time is a Vizio M65-C1. TV does not turn on. I had repaired another 60 inch vizio , Bad main board.
                          When power button is pressed, the Power led indicator on the bottom right, turns for a few seconds and then it fades away. No backlight or Vizio logo on screen. Removed back cover and repeated test.
                          This is the TV This TV is a little different from the Samsung I have worked on. Power supply is on the Left side, Main Bd is on the right side, T-CON , not in the picture is on the bottom. I am assuming that the boards in the middle are the LED...

                          Would someone please help troubleshoot a Vizio 47" TV Switch Mode Power Supply with 5 volt output fluctuating voltage. The voltage fluctuates at 5 the volt output and at the Pulse Switch Modulating IC at VCC. I have the following notes:

                          1. The 3 main filter caps all have approximately 167 volts steady
                          2. I have replaced 4 mosfets next to what I think is called the inventor transformer (big black transformer) pictures attached
                          3. I have replaced Fuse F102 with an equivalent
                          4. I have check all diodes and caps and they seem to be ok
                          5. I replaced the 431...
