    Vizio GV47LFHDTV, No Picture, No Sound, No Powering off

    I want to say that whoever created this website/forum are geniuses. I have gained knowledge and a better understanding of the new model tv's. This site has helped me alot, AND I mean alot.
    THANK YOU BADCAP!

    My dad's Vizio GV47LFHDTV had a black screen issue. The lights along the bottom were lit (amber color) and they were non responsive whether by tv or the remote, either way It could not be turned off.
    I did some research and found other people had the same issue.
    Long story short the problem was the mainboard and that problem is VOLTAGE REGULATORS.
    I order 2 from ebay, swapped them out and voila, the tv is back on. This problem may have a been addressed already but I wanted to share my experience and contribute to the site.
    I included a picture showing the location of the regulators. There are YouTube links that helped me out with testing and soldering.
    Thank you Badcap and contributors. You all have helped me and keep up the good work.

    Vizio M65-E0 No Picture, No Sound
    by ggil44
    Hi I inherited a Vizio M65-E0 that isn't working. It must have been dropped on the corner because I found that the infrared circuit had a capacitor with one end broken off of the board and some green corrosion around the plug to the main board. I re-soldered the capacitor and cleaned the corrosion well and tried turning the M65-E0 on and I was successful. My problem is that while the back lights come on and appear to perform local dimming there is no picture or sound. It kind of looks like you are looking at the TV through a very dense fog, where changing the input on the remote will change bright...

    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...

    by TR103
    Hi, I have a Samsung UE50TU with:
    - sound and backlight, but no picture
    - when it arrived, it had a picture for a few seconds
    - it keeps rebooting
    - without ribbon cable between the two panel boards, it does not reboot but I have no picture
    - without cable between mainboard and lcd panel, it does not reboot (but obviously i have no picture)
    - when i try a tape fix, its keeps rebooting, unless I tape off pin 1 (the innermost pin). In that case it does not reboot but I have no picture.

    - without cable between mainboard and lcd panel and with a jumpered...

    Samsung UN60EH6000F Black Screen, Backlight and Sound Good. Power Cycle Returns Picture
    by Mgiffune
    I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started ‘fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.

    I ordered a supposedly ‘new' Tcon board this time, and

    Samsung UE60KU6079 backlight okay mainboard responsive, no picture, no sound
    by Ierwin
    Hello everyone,
    Ive got a UE60KU6079 on the workbench that is giving me some headaches trying to troubleshoot.
    The previous owner stated that there had been white dots on the screen which from the description sounded like some lenses fell of the backlight LEDs.
    He had opened the TV from the back, trying to get to the backlight, supposedly gave up, reassebled everything and gave the TV to me.
    I expected the worst like ripped COF cables or a cracked panel but could not find anything like that yet.
    Anyway I still fully expect that there has been something seriously damaged...
