    Vizio vo47lfhdtv10a no display

    Hi,

    I've got a Vizio vo47lfhdtv10a tv that, when I got it, wouldn't power up. I opened it up and found a bad capacitor on the power supply board and 4 bad caps on the inverter boards. I replaced all of them with low esr caps. One of the pictures shows where the bad cap was on the power supply board, the board was pretty charred, and I re-flowed all of the solder connections in that area.

    After doing that, the TV now powers up, but I do not get a picture. The Orange led turns to White on the front.

    I checked the voltages on the power supply board and they look good. I also checked to make sure that the fuses were good on the inverter boards, they are.

    Along with the "no picture" issue, the power on/off button works very inadvertently, sometimes working, and other times not.

    Is there a way to test the inverter boards?

    Please let me know if there are specific voltages you would like me to check. Like I said above, I did check them, and but there may be some voltages that I should check that I was unaware of. Or you may want me to recheck ones, which is fine.

    Thanks!

      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.

      by m1ch43lzm
      Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
      Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...

      Looking for help with a Viewsonic VP230mb where the backlight comes on only momentarily
      by lostone
      Hello, I came here after finding some similar questions asked on other monitors and hope someone here can help me get an ancient Viewsonic VP230mp (23" 4:3 LCD) back to working condition.

      First a little background, I have a background in computer and electrical engineering, and I'm smart enough to know I know nothing about LCD displays and how they work. For this topic I'm as green as they come.
      When the display is turned on the viewsonic logo displays in the uppper left for 2 seconds then the screen goes black, the power LED is green (on) and when a computer is connected...

      Hi.

      LG OLED77G1PUA - No Video / Audio after a TCON Board change and Software Update
      by Hakuu
      Hi There,

      This TV was auto switching off after few seconds with some vertical lines on the screen, so got a new TCON board and replaced it.

      After replacing the TCON board it was working fine and i set it up with everything, used for few hours, then had the bright idea to update the software on it. During the update process, TV switched off and now no audio or video. No relay switch sound.

      More Details
