    Re: TCL L65F3500FDS issues - Tcon, panel, or ?

    I've ordered the replacement tcon board from the US, so this thread will likely be on hold for a few weeks.

    I have reassembled the tv for now, but I can say that unplugging the tcon board resulted in a crisp white screen with no distortion. I never saw any colour tests but I didn't unplug the ldvs for very long

        you can see that what it seems a tcon problem (screen divided into 2) is in fact a mainb. one, you can do the test of that user, unplug the tcon lvds cable and see if a self test appears.. Anyway if you say that dismounting the screen bezel and touching screen tabs makes big difference in the video then is a screen problem..
        Touching the tabs did nothing. Fingers crossed is the tcon board. Will update in a few weeks once the replacement arrives. Thanks to everyone who has replied

            when you say "unplugging the tcon board resulted in a crisp white screen with no distortion" ... did you mean "totally" as in both tcon to panel cables at the same time.... or just one of them?

                Well yes, unplugging both would turn the entire screen white; but unplugging either the L or the R cable, by itself, would result in just that half going white.

                    ok but the half. that wasn't white.... what did the picture show? feed in a good test pattetn (ie. color bars) and look carefully at the result. go from there.

                        Replacement came in. I installed it only to realise it was missing a connection (see picture, top right of each board). Not ldvs, but not sure what its function is.

                        Anyways. Plugged everything else in and flicked it on. Problems has changed but it all still seems pretty fucked.

                        Soooo I'm selling it off to the next person who wants to have a go. Thanks for all the replies in here, maybe one day I'll return to the tv repair game, but for now I'm gonna do it the easy way and just buy used

                            You bought the wrong board. The number you should have quoted when ordered was: the number on the white paper label and NOT the number on the board.

                                    Sony KD-65A1 Repair – 4 Red Blinks Error
                                    by AK_777
                                    Hi everyone!
                                    I have a Sony KD-65A1 TV with a fault – 4 red LED blinks. After disassembly and visual inspection, I found that the G76 power board and DKA board had been replaced. It is also possible that TCON was replaced, but I am not sure – there are a few marker marks that could be factory-made.

                                    Based on assumptions, the previous service attempted to solve the issue by replacing potentially faulty components. I decided to investigate further, found a service manual, and figured out a way to power up the power supply unit autonomously and put the OLED panel and...

                                    Sharp LC-80LE844U Blinks 2 slow, 5 fast
                                    by joblo37pam
                                    It's been a while since I've checked in here or needed input on narrowing down what to replace on a TV repair, but I've got one on my bench now that has me wondering. The lack of part (board) availability means I may need to do some component-level diagnostics, and a second opinion is always good when it comes to that.

                                    The issue - Sharp LC-80LE844U does not display. Power light comes on for a while, then you can hear a relay click off and the light blinks twice slow, then five times fast. Service manual points to 'Panel Power Supply Error' with this code, but isn't much more help...

                                    Driving a Sharp TCON/panel with a universal main board
                                    by advant
                                    This thread is about trying to get an Universal Main Board to work with a Sharp TCON and panel.

                                    I have a Sharp LC-46D85UN TV that has had a main board issue. Since this model is from 2009, I am not able to find an exact replacement of the main board. Instead, I decided to see if I can future proof this tv by getting a Universal Main Board (T53U21.2) from China to work with the Sharp TCON (CPWBX4291TPZA) and panel. The universal main board supports a 8 bit dual channel LVDS interface whereas the TCON requires a 10 bit dual channel LVDS input. I have modded the LVDS connector to match...

                                    Sony XBR-55A8G 4K OLED image ghosting/jumping around

                                    Hello All,

                                    Hoping one of you wizards might be able to help me, I'm new to TV repair, I'm trying to troubleshoot a ghosting/jumping image on a 4k 55in Sony XBR-55A8G OLED TV.

                                    I have tried re-seating all cables, and lightly manipulating the cables while the TV is on to see if the picture changes with pressure on any of the cables/connectors. I also replaced the TCON board and the ribbon cables connecting the TCON board to the panel, the issue has not changed with the replacements or with any cable manipulation / re-seating.

                                    I saw some people had success...

                                    Hi all,

                                    70" LED TV is Sharp LC-70LE650U.

                                    Initial problem was horizontal lines and slow motion lurrs on the bottom left of the screen. So I removed both the left and right ribbon cables from the T-con board and tried to clean it with alcohol and when I put it back, this issue appeared. I tried carefully reinserting the ribbon bon cables but same thing. I checked the traces of the ribbon cables with magnifying glass and everything looks good. I cleaned the small jumper ribbon cable on the left side of the screen which cured the horizontal line and slow motion blurs...
