            OP, you got a good picture then it disappeared... wth!!!! :-(
            I would say you are close then. One question, when the picture happened to be good, what was the input?

                You need to try other inputs and signal types.

                        Not tried any other inputs I just tried ps4 via hdmi but tv is not switching to hdmi so looks like I need a remote to change source, tried several lg remotes I have but none working this tv, (except for power on off), looks like I will have to get a remote for this tv to change its source

                          :-( guess your "friend" didn't have enough money to give away the remote... :-)

                          have tried reloading the firmware?

                            The tint evindently depends on the picture content..

                                a quick look at the manual appears to indicate you just need an app to control the set.

                                  will get a remote for it, and take it from there, ie changing source, reset and update etc

                                    An hint to get replica remotes at lower prices, search on ebay the remote with the tv model followed by remote, then view some of the results, in some of them there are the remote code, model, then search for that code.. i usually pay them 10 euro with a good replicas...

                                          looked at the app but did not try it looked like I had to pair the tv with the app via wifi settings on the tv, can not access any tv settings at the moment
                                          remote I have ordered has been posted first class so should have it tomorrow all being well

                                            Hi,
                                            I have a VIZIO E70-E3.
                                            Symptoms: Black screen, no picture, but LED backlights are working.
                                            I probed the power board and voltages are as listed on the board.
                                            Main board appears fine, too.
                                            I believe the problem is either a bad T-CON board, or connection to LCD, or bad LCD.
                                            There are two separate ribbon cables feeding the LCD.
                                            If both are connected, the screen is black.

                                            If only the ribbon cable that feeds the right side of the screen (when viewed from the front) is disconnected, the left side of the screen shows picture and...

                                            LG 82UN8570AUD ~ TCON or PANEL?
                                            by kca
                                            Hello all ~

                                            Hope this finds you well. This LG 82UN8570AUD (April 2021 model) 4K UHD television has full audio capabilities but video is compromised / problematic.

                                            When I picked up this large LG tv it had a full black screen upon startup. Previous owner said it just went black one day. No popping sound or anything else of note.

                                            I got the display to work by taping off several traces of the right-hand side ribbon cable on the TCON that leads from TCON to PANEL. However, despite dozens and dozens of attempts to find the right combination / range of traces taped...

                                            Samsung LCD TV no picture backlight on no 12v at tcon
                                            by shelby5041
                                            hi
                                            i have a samsung lcd tv

                                            it powers on with sound and backlight but no picture

                                            all voltages from PS are good 12v 3.3v and 5v

                                            whats odd is that at the tcon i tested voltage across the fuse on the tcon and i get 0v

                                            i figured main board issue..so i ordered a used main board....when i put replacement main board in i still have same issue

                                            no 12v at the tcon fuse

                                            i disconnect the panel ribbon cables to rule out any panel issues and i still have no 12v at the tcon fuse

                                            This was my main TV for the last 6 years. I'm not inclined to throw out a $2600 TV so quickly so I'm trying to investigate the issue.

                                            Problem
                                            TV was disconnected from power for 6 months during construction. When I plugged it yesterday picture was fine, after 30 seconds it dimmed then started developing horizontal lines, picture then starts to ghost vertically until it degrades into vertical streaks. TV always displays a perfect picture when cold. I can unplug TV for 5 minutes and plug it back in and picture is restored for 20 seconds. I can also keep it in standby mode...

                                            Samsung TV model UE50TU: rebooting, backlight, sound, but no picture

                                            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...
