    LG 42LV5400 panel failure or internal board?

    My gut tells me panel failure. The menu shows the same condition.

              Only a guess for me but don't think it is panel. Lines look like they go across full screen. Usually panel is only on part of the screen.
              I assume no responsibility for any stupid suggestions I might post.

                  As it's an LV i'd suspect it's the BGA on the mainboard.

                      i'll put a vote in for main board. looks too even to be panel to me, but it is only my guess.

                      you will always be able to isolate it a bit more by disconnecting one side of the t-con and see if the fault changes at all.

                          check lvds cable...reinsert it or apply wd40 to both connectors..this will fix this problem.if not then motherboard is suspect

                              Hi,

                              Your symptom looks a little like the issue I had with a 42LV5500.
                              Here is my post.
                              https://www.badcaps.net/forum/showth...light=42lv5500

                              I didn't believe that baking the main board in the oven would fix the problem but the tv is working for well over 1 year.

                              Good luck - I bet it's a main board issue.

                              Mike

                                  I'll try to reflow the processor and see if it makes any difference. Thanks guys.

                                      Just reheated a LV5500 on the BGA, came back to life. I'll vote mainboard, main processor

                                          +1 did a few of these.

                                              Well, seems like that's what it was. A shame this thing doesn't have Wifi. Would any USB wifi dongle work or does it have to be an LG branded one?

                                                  Firestick should work.

                                                              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.

                                                              I’m troubleshooting a Westinghouse WD55UW4620 with a strange, very repeatable failure mode and I’m looking for insight on whether this points to the panel itself, T-CON/FRC board, or mainboard.

                                                              Any ideas as to what would cause these symptoms?

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

                                                              Hi all,
                                                              I have an LG 55UC970V-ZA (around 10 years old). The picture is normal right after power-on, but after ~2 seconds vertical bands/lines appear across the screen. Then it clears again, and the issue repeats in a cycle (roughly every 2 seconds).




                                                              Symptom (repeatable):
                                                              - After power-on, the picture is normal for about ~2 seconds.
                                                              - Then vertical bands/lines appear across much of the screen.
                                                              - It happens on everything, including the LG boot logo and the TV’s own menus/OSD, built-in apps, and all HDMI inputs.
