    VIZIO M65-C1 Does Not Turn On
    by Mulp
    Hi All,

    I am having an issue with my Vizio M65-C1 where it does not turn on. When I plug it in the stand by light on bottom left of screen turns on (white) then fades away. If I press the power button it turn back on and then fades until it is super dim.

    When I remove cover, there are no illuminated leds on the main board, I've seen others with a red/blue led that turns on.

    I've done some research and what is interesting is my voltages all seem slightly different from other people. For example +5/3.5v is 3.48V when on which is different from others on here....

    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 V705-H3 Won't power up
    by EazyBone
    This TV has the white light on the front. When you click the power button or hit the remote nothing happens the lights stays solid. I checked the main board for the voltage for that signal and everything is fine.

    The power supply is giving 13 volts and 2.7 on AC detection. Zero on PSOn and nothing changes when hitting power. The led lines show zero and those caps won't turn on
    ​​​​​​ it seems the PSU won't turn on to supply voltage to LEDs. The main caps sit at 170v.

    It's odd to me the led lines go from PSU to main board and THEN to LEDs.. as a note....

    MSI GF63 THIN 11UCX (MS-16R6) LAPTOP WON'T TURN ON AFTER RESTARTING
    by RdeveLabs
    To all the members here...

    Let me tell you a little bit about what happened to my laptop (MSI GF63 THIN 11UCX model: MS-16R6) that “maybe” you know how to solve this problem.

    So before this problem happened, my laptop was running smoothly. When I wanted to restart my laptop, it looked fine at first. But after I waited for this restart process to take a long time, until finally I panicked (because the restart process did not finish plus the laptop screen only showed a black screen), I immediately pressed and held the power button to force the laptop to turn off. But...
