    I think you took a wrong turn at 6:22 "the blue line is not there anymore". With that half of the LCD disconnected, it defaults to letting the backlight through. Which means that red, green and blue LCDs are all transparent. So it's not that the "blue line" isn't there, it's that the pixels of the blue line have been joined by pixels of red and green, so it now shows white. So the symptom is still there, you just can't see it. It also teaches us that the type of fault is that the blue line region is behaving as though disconnected, even when plugged in to the T-conn board. That means the conductor from the chips on the T-con board to the LCD panel is broken somewhere (or a chip output on the T-con is bad). That doesn't narrow it down much, but it's so frequently the flex cable (or a chip-on-flex, "COF") that's broken that it would be there to look and poke around.

      I had the same thought as you, when he disconnected the half of the screen he should have realised that disconnecting it wouldn't help much in diagnosing the problem. Since the power supply was clearly working like it should have, and the tv displayed a whole image (at 0:33 it is clear that the image signal is there, becasue the white text "overwrites" the blue line, so it would display an image but only the brightness of blue color is shifted in that column of pixels for some reason), so replacing the main board was quite the unnecessary thing to do. I would have poked around the ribbon cables trying to find some speck of dust somewhere, or I would have tried tightening all the bolts (it's not common to fix something by thightening the bolts, but it's free if that fixes it, so worth a shot), or put pressure on the thin ribbon cables that are soldered (maybe even try to persuade the lcd to work with light tapping on the screen itself near the line) and if everything failed then I would have also decided on buying a tcon board. But i would have probably given up after replacing the tcon board and trying the things I've said, because it's probably something unfixable on the lcd or one or two of the traces on the thin soldered on ribbon cables are damaged and that's quite hard to fix. The one thing he did and I probably would have forgotten to try it is switching the two ribbon cables from the tcon, if you are lucky that's one easy fix.

    Ive "repaired" a microsoldered ribbon cable on a SONY tv that responds well to pressure by inserting a rubber shim in between the case and ribbon so that constant pressure is applied once the casing it replaced.

    • @joeschalk4263
      @joeschalk4263 2 года назад +1

      This was going to be my suggestion too. I did it from an old Sony from 2010 era. We used q-tips to keep the pressure on it and it still works today but the issue was more severe than a single line. This looks like a bad trace or maybe a shorted diode on the display board since the “tcon” board was replaced without success. Seems to be a zero or open voltage issue. I have an ONN 70 with the same issue that I was told to just trash from the factory due to this.

    Tried this and several other recommendations without success as yet. I only have ONE green vertical line, it is clearly dots running up and down. In that line there is one missing dot. Might that tell me anything? Like maybe it is the actual screen rather than anything else? Would love an answer from anyone with any thoughts on this. Thanks!

      @@peterwaldhauser1907 I tried everything mentioned on several sites. In the end it was the panel. No fix other than replacing the panel or TV. Too bad cause that set has a really great picture. I have a 65 & a 50. Probably gonna get a 75 to replace it. Sadly, most of this stuff nowadays seems to be junk, even Sony. Be sure to take the back off & run your finger or something along the edge of the panel firmly. That one works sometimes. Good luck!

    So when you disconnected each side of the TCin board and the side that had the blue line was white, of course there was no blue line. The main board is aka the Logic board, and, from what I understand, simply takes commands, converts signals, processes pictures, all the programming and control and such. The power switch plugs into that board and the AC plugs into the power supply board. The power switch being pressed complete a circuit momentarily and sends a signal to the logic board and then to the power supply to initiate power up, where the power supply then sends power to the processors in the Logic board and then to all of the lighting, and T Conn board so it can do it’s conversions of commands into the correct combination of RGB to produce the picture being sent by the Logic board from your input source. There are more chips on the PCBs adjacent to the panels so that means more processing. So I’m figuring the screen is divided in half, each side getting 64 connections via that notorious ribbon connector, one per side. I don’t know what kind if signal that is sending, but I suspect that it just continues to break down until each pixel gets its own signal, which must be the end result such that we can get such resolution. I’m sure I’m oversimplifying a little bit. But the dude tried the ribbon connectors a couple of times it seemed, and then decided the TCon was bad. Then, the one he gets is from another fix it dude, who declared a broken screen but that the TConn was still good. You know how when you short an extension cord, the breaker trips in the breaker box, potentially a longs ways away? Have some people considered that these things have progressively gotten lighter and of less robust integrity, but that they really are better pieces individually. The other night while preparing super glue to fix a broken connector, the bottle cap seemed locked but wasn’t and the bottle flipped over and over to the ground leaving streaks of super glue on a 55” screen I had almost fixed! I tried everything. Rubbing alcohol, fingernail, you name it, even 1000 grit sandpaper, but in a tiny spot. Well the screen was either toast already or if I couldn’t get the super glue off, it was still toast, so I carefully added progressively more and more pressure in circular pattern with rubbing alcohol on a microfiber rag, and got 80% of the glue off. Finger nail did nothing, sandpaper left scratches were I swear it never touch. Whoops. Ultimately, I got it down to barely noticeable, but what’s noteworthy here is not my screw up, but how much pressure I could apply without ruining the screen. I couldn’t believe it honestly. I mean rubbing about as hard as you would on a bathroom mirror to get a stubborn water spot out, and it always recovered. I did find a crack in that screen, but learned a lot since I had two identical TVs, one with broken screen, one wouldn’t stay with a pic showing. It would seem to turn off, but in reality it was just the pic, and the Tv and backlight were always on. I swapped parts with the other TV starting at the power supply, and nothing changed, even after changing the TCon board. That is until I tried to clean the two ribbon connectors with alcohol and carefully reseat them over and over, and over again, because I knew for a fact that the screen I was working on was 100%, just wouldn’t turn on, and in the process I would get no backlight, one side perfect, one side dark, one side with horizontal lines, and on and on, until I got it to only have vertical lines near the right side. Still convinced it’s in the ribbon connector. Maybe a connection in the middle if the ribbon is “compromised” and if it’s bent just right it works, and maybe the wind blows the wrong way and it doesn’t. So I’ll test continuity and then try the other ones, I’ve got four. Dude here made too many jumps in deduction and loose conclusions. The new TConn board may have issues. It could be maybe that when a screen takes physical damage, like a screen breaking impact, connectors touch that are not supposed to, and especially if time elapses, other components could be burned, shorted, open circuit from a burned connection, etc. So just because the screen is broken you can’t assume every other component is good. Especially in this world of microprocessors. They have safety measures and self preservation too, but not on everything. If you were to shirt two wires in your car before the fuses, where say power to the fan hits power for the computer, pre fuse, or post fuse, depending on voltage differences, amperage differences, or if hot hits ground in the wrong place for too long, which is the case in flooding damage. The systems never work the same again. Who knows what could be damaged by screens breaking. I know that with speakers, as I work pro audio for a living, if the driver gets physically damaged and there is a short on the voice coil or anywhere along the path, the amp will see that short, and the nicer amps will keep trying to perform, as “the show must go on”, but sooner or later, the amp will eat itself. Generally there are other symptoms. But you’d be surprised how oblivious people are to things which are telling them there is something wrong and they just blow it off as “one of those things”.
    What things? Those things my ass.

    I'd say it's still that display connector that's soldered on. Since we've determined the tv is toast because the most expensive part of the tv (the display/screen) cannot be salvaged here's what I would try. I'd get a hair dryer or heat gun and heat up that panel connection to maybe reflow the solder within the connection. If that doesn't work, I'd heat up the connection again and pull it off to see if I could re-solder it correctly. Again...we've already written it off. Even if you mess it up beyond repair, who cares?

    Thanks for the idea to bust it down for parts! Idk why I haven’t thought of that as I’ve been building PCs since 2007 and always sell parts when I upgrade. I only thought of selling the whole unit locally as is. Guess I was just so upset at the whole situation. I bought an lg cx oled and got 21 months of light usage out of it. Panel had 2000 hours on it. Went to bed with tv working, woke up 4 hours later to a thin yellow line down the whole panel. Lg wouldn’t help even tho it’s a defect. I guess I get it, but I’ve also heard many people on Reddit with much older oleds that got courtesy panel replacements so I figured I’d try. So I sucked it up and bought an lg c2. Paid $159 for a 4 year extended warranty. Something I never buy. If only I had bought the 3 year for $119 I could have saved myself a lot of money and heartache. Oh well lesson learned.

      No but it was funny. When I first watched the video I knew it was the panel. It was funny watching them buy all those parts for nothing and thinking he can sell them on eBay. The problem is with these TVs is that there's a lot of panels that go out and people sell the rest of the parts on ebay. There's a shortage of panels and plenty of power supplies, t-con & main boards. My Samsung 4K 32-in M7 monitor has a black vertical bar about two and a half inches wide, with a quarter inch wide white line, almost in the center of it. It's about the same width as the tab and in the same location. It's almost new, so no dust or dirt and I'm wondering if it's the main board or the screen. There is no t-con board in it. I watched another video where they said remove one of the ribbon cables next to the black line and see what it does. The screen was completely black when I did. I didn't try the other one, I wanted to learn a little more first. I cleaned the connection and put it back together and have the same problem. How do you know if it's the main board or the screen? I can buy another main board for a hundred bucks. But most likely it's the screen. So I bought another broken TV on eBay where the guy said it won't power on and he said the screen looks okay. But who knows sometimes you buy stuff on eBay and it has a bad everything as people repair TVs and then put all the broken parts in a broken TV to sell it on ebay. I literally bought TVs that had bad main boards, bad power supplies and a bad screen all at the same time. Then when you buy a part on eBay you not sure if it works.

    First of all... NONE of these type of problems would happen if they hadn't banned using LEAD in solder.!

      First, lead in solder is a HUGE environmental issue. It was banned for a reason. Second, bad folder connection Helen so there time, regardless of whether or not there is lead in the solder. Making such a blanket statement is useless.
      Third, microsoldering, rule a bit more involved than macrosoldering, is still trivial.
