    Vizio M65-C1 | Logo appears for 10 seconds then off
    by Bob1394
    I have used the search, and am stumped.

    My Vizio M65-C1, Vizio logo appears for about 10 seconds then goes off.Power LED blinks 15 times then the TV powers down.

    I have read through many threads on the M65-C1 including the following threads. I feel like I must be looking right past the solution to my problem:

    Dell u2311h 20000 seconds to black issue
    by ChIck3n
    So I've had this monitor for probably a decade now, and it's finally starting to fail. Began with a little sporadic flickering, then eventually started going black (power LED stays blue, can still see image on screen with flashlight). A power on/off fixes it for a bit, but then it happens again. Once it got to the point I was dealing with this every few minutes, I opened it up and just replaced all the caps (minus the big one) on the power board with new Panasonic ones. All the old caps tested fine on an ESR meter, and this worked for 5 days. But the screen just went black again today, so...

    Vizio E321VL - 2 Seconds to Black
    by bobbyskillz
    Hello, friends.

    I've been making progress with a Vizio E321VL that was victimized by an apparent power surge. On the PSU it took out the fuse, a SMPS IC (FSQ0465R), and a MOSFET (FQP13N06L). Now I have two seconds to black. After replacing those components, all the power at the cable going to the main board seems proper, except VBR_B drops from 3.3v to 2v gradually after the backlight goes out.

    I've poured over other threads here to get some clues, but none appear to have a solution for the same problem. I've tried disconnecting the IR receiver board; it didn't work....

    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...

    LG 37LG5020 and the tale of 2 seconds to black.
    by DrankinSAW
    I bought an LG 37LG5020 with a very strange issue.. it turns on, the display looks fine, but still, after 2 seconds, the TV shuts the backlight off..

    However, if i leave it plugged in for 20-40min.. the time it takes to shutdown the backlight, doubles (to 4 seconds)..

    I bought a new inverter, set to arrive on December 13th
