    Vizio E321vl Won't turn on only amber Vizio light

    So I got a Vizio E321vl that wont turn on all I get is the Vizio name on front to come on amber. The problem that started it all was the power cord was chewed on while it was on and now it has this problem. As I was testing the voltage I happened to notice that the Vizio light had gone off even though it was plugged up and has not come back on

    I read this already and didn't find much

    1)I have a multimeter and measured the voltage across 5.1sb when the Vizio light was on they were all at 4.94 and after they were all ~5.1-5.19
    2) Tested the PS_ON it stayed at 0.00 even when the power button is pressed.
    3)I tested the main capacitor it registered at 168 then would go to 174,171 and then back to 168 and repeat
    4)The fuses on the logic board read F1 at 5.13 and F2 at 0.00


    from this point I don't know what to test and or what is wrong with it any help would be appreciated.

    I tested the voltage regulators with black on ground(one of the screws) and they all registered zero volts could that have to do with the fuses

      The fuses can be tested; measure the voltage on both ends, with the red probe on one end, black probe on the chassis of the TV.

        main fuse on power supply is 0.03 and the two fuse on the logic board are F1 5.13 and F2 at 0.00

          Both ends?

            F1 gets 5.13 on one end and 0.00 on the other and F2 get 0.00 on both ends

              Macbook pro A1278 820-2936 No light/turn on
              by Adogabriel100
              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....

              I have a similar problem... I got an old MBP for free, but wont turn on... Only green light on charger. I measured these voltages. If i try to do an smc reset using keyboard, nothings happen, wont go out the green led. I dont know how to continue, please help me.

              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
