    Vizio E470VL

    Vizio E470VL will not turn on. Amber Vizio light comes on, but screen remains black and Vizio light will not turn white. TV is unresponsive to the remote control and manual button on the TV itself. If I press power on either the remote or the TV, nothing happens. It doesn't turn off and it doesn't turn on. The amber light remains lit up. Cannot change input, channel, etc. Nothing but a black screen with the Vizio light lit up amber. The amber light will only turn off if I unplug it. Will not turn white regardless of what I do. I opened up the back and I don't see anything out of the ordinary. Any help you can provide would be greatly appreciated. I've attached a number of pictures.

    Thanks

    Re: Vizio E470VL

    I just finished writing How to test a voltage regulator. See my sig file below. It may or may not be your problem, but since it is a Vizio, it is worth 15 minutes of your time reading and testing it.

      Test all fuses and list them with a numeric result eg main board F2 2.6 ohms
      Please upload pictures using attachment function when ask for help on the repair

        It sounds like you're having a problem like I just had with a 42 vizio. I fixed mine by replacing the mainboard the other day. The symptoms were the same. I had power out from the power supply to the mainboard, but no power was coming back from the main board to the power board.

        Do a quick check of all of the regulators as previously suggested. They are usually 1117's that fail a lot on vizio's. Measure each leg to ground and post the readings here.

          Hey! how are you guys? i wonder if you could help me with this macbook 820-2936 that does not turn on. (Doesn't have green/orange light).

          History:
          this macbook came for a short on C6990 that blows D6990 and R6990 on his way. i re-placed the componets and it work again.

          A month later comes back again and has the actual problem (no green/orange light and dont turn on)

          The macbook can turn on with only the battery connected but in fact, dosent charge.

          Voltajes:

          PP3V42_G3H = 3.3v
          PPBUS_G3H = 12.2V

          Vizio SV422XVT blinking amber/white power light
          by What?
          Good day, hope all are healthy and cozy. I could use some help with my malfunctioning Vizio with a blinking power light. I have narrowed the problem to the main board but not sure what to do next. I guess it would be good to start with what I have done.

          Problem:
          I have no image, no sound, blinking power light. (left it plugged in overnight and it was still blinking the following morning). I tried the Vizio recommendations (hold power button for 30 seconds, press reset button, check the outlet is live)

          Power Board:
          I am getting 5v only. I have unplugged...

          PS5 Slim EDM-040 Only turn on 1 Sec, Blue light then immediate off.
          by dionzarek
          Hello everyone, I am new to this PS5 troubleshooting, I need help on diagnosing the problem. My PS5 Slim board EDM-040 that beep and only shows blue light then immediately turn off.

          I've checked the PSU its normal 12V. I've checked all the capacitors its all good no shorts, but there are 2 caps shorted, I think its near the SSD. You can look at the image attachment.

          When tested it only shows 0.003 while other caps show 0.4 to 1. WHen in continuity mode those 2 caps goes beep/shorted.

          Any help to where should I check on or suggestion would be very appreciated....

          HP laptop does not charge the battery, the light turns amber and then changes to white.
          by stevenallauca
          Hello everyone. I have a problem with an HP laptop, when connecting the charger the amber light comes on for 6 seconds, changes to white and does not charge, I have checked all the components with the multimeter and the values seem correct, I was guided by the diagram, I do not know if it is a problem with the BQ24728H charge controller, investigating it seems that the voltages given by the charge controller are correct, I made the measurements connected to the power source and without the battery:
          - ACN (BQACN) 19.6v
          - ACP (BQACP) 19.6v
          - CMSRC (BQCMSRC) 19.6v
          - ACDRV...
