    Almost always it will buzz if that is the case.

      Well, there's no buzz so I guess that's promising.

        You need to check in a dark room, if the panel does not glow, then something is wrong, but otherwise, I expect a dim glow to be visible.

          I checked it in a dark basement after the sun went down. I don't see any glow whatsoever.

            Very odd, it does worry me that there is a panel fault, but I have never heard of an LG with it...
            It could still be a Y-buffer fault. Cannot rule that out at present.

              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...

              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...

              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

              TV Model - LG OLED77G1PUA

              Got the same exact TCON board from TVPartsToday and replaced it. But didnt transfer the EPPROM data (didnt...

              Sony xbr-65x900c main board issues?
              by jb_Bak
              Hey guys great forum glad to have found it. I bought a Sony XBR 65X900C cheaply because it didn't work. No signs of life at all not even a light/led. All I hear is a brief high voltage sound when I throw the power to it.

              Didn't see any obvious signs of damage so right away started checking voltages. This is what I see:
              Power Board Connector that goes to Main board
              CN6401
              Pin 01 NC
              Pin 02 NC
              Pin 03 "BL_ON": 0V
              Pin 04 "N/C"
              Pin 05 "STBY 3.3V": 3.5V
              Pin 06 "GND": N/C
              Pin 07 "AC_OFF"...

              Panasonic TC-P54VT25 No image. A or D board?
              by canadaboy25
              I have a Panasonic TC-P54VT25 that will power on and prime the display but there is no image at all.

              The panel is primed as there is a slight glow from the entire panel. This means the problem should be logic related. The service manual also confirms this and recommends replacing the A or the D board.

              I have tried to get the TV to display the test sequence but I have been unable to and I don't even know if this TV has a test sequence or not. I tried following tom66's instructions in post #3 on this thread https://www.badcaps.net/forum/showthread.php?t=26790. There was...
