    I've repaired the same fault on an LG plasma. See here

        What does it solder to inside the shielded box? There was what appeared to be a thin, flat wire that broke off.

            maybe we can tell if we see the inside that shielded box.

                I'm reluctant to start unsoldering stuff from the main board until I have a better idea.

                    The thin flat wire is the terminal that is connected to the center pin of Ant connector.
                    The tuner module has metal shield where the Ant connector is attached to it and the center pin of the connector is soldered to the PCB.

                        Mine was done in situ through the hole with a pencil iron and a little flux. No need for removal.

                            I cant seem to access where the thin flat wire connected without removing the metal shield. I certainly cant see it through the hole.

                                To be fair mine was a solder pad and not aflat wire so iI'm not sure you'd be able to properly anchor it anyway.

                                    • TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
                                    • Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault

                                    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.

                                    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

                                    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:
