    Vizio E48u-D0

    I picked up this tv for next to nothing today. Everything seems to work good except the backlight. It flashes on and off repeatedly until I pull up the menu, then it’s fine. I’ve noticed the SmartCast app on my iPhone allows me to adjust the backlight. I figured out as long as I keep it lower than 60 it seems to work perfectly. If I go past 60 the flashing starts again. I updated to the latest firmware hoping that would fix it but obviously it didn’t. I also noticed what appears to be dried syrup from a spilled drink on the power supply. I cleaned it up as best as I could but it had no effect on the flashing problem. I’m thinking it’s either a bad led strip or the power supply has issues. Your thoughts?

    If you can turn the backlights level down and the backlights stay on longer then I suspect the LED's or the inter connectors issue.
    Please up load good clear pictures of the back of the TV showing all the boards.

        You can see where the liquid ran down the chassis.

          Seems like typical weak/bad led/s, you could run the backlights as low as possible, that gives you an acceptable picture, might last quite a while like that.
