Samsung TV Vertical Lines
Вставка
- Опубліковано 26 вер 2024
- I have an older Samsung plasma TV that developed some colored vertical lines during the past year.
Most of the time a simple cleaning will fix the problem so that is what I am attempting during this video.
It may work, it may not. It could be a number of other things, I am simply trying something that doesn't cost anything and that anyone can do at home.
Hopefully what you see here can help you if you have a similar problem.
Thanks for watching.
Watch my update video here: • Update: TV Vertical Lines
This model is Samsung PN50C550GIF-XZC
The T-Con board is LJ41-C3382A
** UPDATE **
Here is how I eventually fixed mine. If you remove the back panel, you will see all around the outside edge of the panel something called a COF (Chips on film) it is a flexible circuit board that is glued to the panel which is how it makes its electrical connections. The glue has probably let go in one area. To find it turn the tv on and press the film all around the panel until the lines go away. This is the spot where the glue let go. You won't be able to re-glue it but if you put something non-conductive against it so it will always press that spot while the cover is on then it should complete the circuit and the lines will go away. I can't guarantee it will work but it doesn't cost anything to try.
Thanks Paul. Even though it did not work on your Samsung in this video, your advice helped me on a 2 year old Hisense 55 inch TV that I picked up on facebook marketplace for free. I learnt from you how to disconnect the cables and I cleaned them with an alcohol swab. I put it back together and it works perfectly. The problem was the picture was displaying perfectly but would fade out after 5 minutes. Cleaning it and reattaching the cables fixed it. I am over the moon.
cmon guys.... this guy actually awesome for what he did for smart access to everything and best instruction ever.. if he fixed the tv by just changing the tcon board will make him star..
Thank you. There are so many people giving me bad comments that it is nice to finally have a positive one. I appreciate the time you took to write this. Have a nice day.
Thank you so much for this video! I tried this on my TV and it worked! I used a can of compressed air instead of the contact cleanser though. I fixed my grandparents TV with the help of this video, and saved them a lot of money!
wow
For me it doesn't matter whether it worked or not,the video was educative and worthwhile.
Thank you
This didnt help me in any way by my problem with my gaming monitor but I got entertained so, thumbs up ! 👍🏻 greetings from germany
Not sure why you are getting hate. It was entertaining (well, as entertaining as this kind of video can possibly get) and honest.
Hey 2021!! This really helped me ! I fixed all the lines on my tv ❤️❤️❤️❤️
Hi Paul,
I just came across your video, and I really thank you for the time and the candid explanation. Greetings from Buenos Aires, Argentina.
I don’t feel as confident in trying this as I did at the beginning of the video but I’m gonna give it a shot anyways 😂 thanks for the video!
How did it go?
@@chato209 it exploded and Zeus died
@jass singh are you speaking english?
@@DanielMartinez-gz5ou haha.
Paul, thanks for taking the time to do this video. My Samsung 46" (UN46B6000VFZ) TV has the vertical lines. Cleaning all the cabling didn't get rid of the lines. Maybe it's my T-Con board and it's time to replace it or the entire TV.
On a side note, I'm not sure I understand all the negative comments left below. I find it great that you took the time to put a video together for this problem. And as far as your use of your Google device, I was kind of impressed so keep it up...
Thanks again Paul.
Thank you for the kind comment. I don't get many on this video.
There is one other thing that you can try. Remove the back and you will see all around the outside edge of the panel something called a COF (Chips on film) it is a flexible circuit board that is glued to the panel which is how it makes its electrical connections. The glue has probably let go in one area. To find it turn the tv on and press the film all around the panel until the lines go away. This is the spot where the glue let go.

I can't guarantee it will work but it doesn't cost anything to try. Hope this helps.
@@PaulPomerleau I tried the COF thing with no change at all. This screen shows horizontal lines stacked vertically, see link; photos.app.goo.gl/MS9pZS9QKNQeAtCF8 Whenever anything is displayed the vertically stacked horizontal lines appear. If the TV is on with the source turned off (nothing being displayed) there will be NO lines at all. I did place an order for a new T-Con board and am waiting for delivery. If this doesn't work, then that's that... Again Paul, thanks for the assistance and advice. Jerry
@@PaulPomerleau Hi Paul, today you made my day by talking to Google and telling her to do thing for you, That was so great..... So kindly show me on how I can talk to Google the way you did
Please....
Hey Google, gimme back my 7 minutes....
😁😁😁👍
Amen
Brilliant!
Lol

You drove my Google device crazy in your video.
Hey google - fix the tv.
Haha, I never thought of doing that. That's very good. Thanks for posting.
Hahahahahahaha
Google: buy a new TV. Here are the option....
My gosh your the type of person that's funny 😂
😂😂😂😂😂
Thank you for making this video no solution for the lines on my TV but I laughed for a good Solid 10 minutes I appreciate you 🤣
My Samsung has vertical lines. We wiggle the connection where the antenna connection enters the back of the tv to make them disappear. I attributed it to a bad connection at the cable connection point. Have not gone any further.
Hey Paul... You are a good teacher...
Thank you.
Hey Google remove the lines 🤣🤣😂😂
No
😅
Sorry, i cann't help you with that!! But im learning!! Lol
😂😂😂
Google: Go and buy a new TV
My google assistant activated everytime you sent a command. Lol

6:36 - Exactly what I said and how I said it when I realized I put together the second piece of my floating bookshelf the opposite direction after completion and mounting.
Thank You, Paul. This video helped me to fix my television. I appreciate the time you put into making this.
I feel as if you aren't being truthful with your comment.
@@BUSTRCHERRI LMAO
Ya me to🎉🎉🎉
The TCON sends out timing for the panel over a limited number of lines for horizontal and vertical line data for the panel. There is a TAB panel PCB that takes this data from the TCon over two or four flexible cables and distributes it to a further 6 or maybe 8 serial to parallel chips mounted on the flexible plastic tabs between the Tab pcb and the panel itself. This is how a couple of lines becomes hundreds on the face of the screen. Several voltages are also delivered to the panel. The two important ones are a positive one driving the panel cell high with charge and the other is a negative voltage to suck the charge back out quickly. Any panel missing either voltage or both at proper values makes the image seem to ghost or some floating random shading effects. Any break or short in the serial data results in partial images, no image, vertical lines or sectional images.
My 2c worth now.
The problem looks to be occuring on either the connection from the tab pcb to the plastic tab, the actual chip that is on the plastic tab, the connection from the plastic tab to the panel or finally the thin film transistors made on the panel itself. Seems to me to look like a Tab to panel failure in the middle section. If you have seen this progressively get worse from a single line to multiples then the bond between the plastic tab and the panel has degraded. If they suddenly all appeared slightly then got more opaque, then look at the tab pcb resistors and capacitors in the middle section, one may have gone low or high in resistance. The fact that the fault is progressive as it goes down the screen seems to me to show the chip on the tab is not able to drive the charge in the vertical lines hard enough and there is leakage occuring across a couple of outputs.
More than likely, the tab needs either rebonding or replacement. Both considered out of economic repair as rebonding takes a fairly expensive machine (lucky if one of those is near your location) and replacement means you'd have to buy the tab with it's chip from somewhere (knowing the right one to get as well as the same rebonding problem once you have it).
Some people just press the tab harder onto either the PCB or the glass to see if pushing down on the bond improves the image. Commonly done in Sony's with packing under the metal frame, but not so much that it broke the glass. The bond is done with a special tape that when heated and squeezed, formed shorts vertically top to bottom in the tape, but not wide enough to short sideways between tracks. Pressing sometimes re-establishes the bond (momentarily).
Wow, excellent write up. Thank you for taking the time to do this. It will help many people who are having issues with their TVs. Thanks again.
Thanx for your efforts, really helpful
Nice job. I have question where is the t-con for my lg 49uj634v i cant get it for replacement or are some built-in in the motherboard
@@saddle1940 Thanks Stephen!! I have the same tv as shown in this video; with the same issue. I have replaced the control board twice. So are you saying one of the 6 cable ribbons are bad? Thanks in advance!
Did you actually say "Thank You" to Google assistant ?
They are going to take over the world someday. Better to be nice to them now. Lol !!

@@GuacSause you don't get it, they're becoming stronger..
I like the way you presented the video. But as the saying goes, if Plan A doesn't work, go to Plan B - maybe replace the t-con board?
Turns out the flexible circuit board strip going around the panel have contacts that are glued in place. The glue came loose. You can't reglue them so I used a piece of plastic to wedge the circuit against the panel to keeps the contacts together and it works well. It is only a signal wire, no power so it is safe.
Paul, thanks for the tip, I'll check it out. I've replaced the TV now but just want to see If I can bring the old one back, kind of a challenge. I will check on your tip, at this point I've got nothing to lose.
Thanks again! Really appreciate it.
Remember !?
Tony stark summoning Jarvis ...Casually...
Some panels are easy some are tedious... Easy ones have a ribbon connector on both the tcon AND the panel itself. If cleaning the ribbons doesn't help, the tcon might be bad. Only ever is the panel bad if it has had trauma. The hard TV's to fix are ones that have glued on ribbons on the panel. Those require a heat gun and firmly pressing the ribbons. It won't always work, and if it doesn't, consider soldering the ribbons instead of the original glue that's on them. Simply apply solder to the ribbons only, then align them to the panel, and heat gun it till the solder melts. Don't forget the flux!!!
Finally, someone who gives a constructive comment instead of the others who tells me to delete the video. Thank you for posting this.
My lines where caused by spraying glass cleaner, directly on the screen, instead of applying to the cloth. The cleaner must be able to penetrate the seal. First time it happened, it was still under warranty and repaired with a new screen.Remembered to apply cleaner to cloth and no problems, until forgetting the last time I cleaned the screen, and now have the lines again, and out of warranty.
I have a few red and black vertical lines in the middle of my 10 year old Samsung 52 in tv but they fade away after about 45 min. They do come back when the tv is off for awhile.
Good Video- I had a feeling that it wasn't going to work also but I picked up some tips-thanks Paul
Great cool video, im here because im looking at bringing a Sony Bravia back to life so to speak, it is displaying vertical lines at one end of the screen
Did you fix ur TV, my bravia too displaying vertical lines at right end 😔
I replaced the back light strip on one of my tv's and it works perfectly fine now. Check into it.
Wow, that was an eye opener. to bad i put my tv in the trash, i could have cleaned the connections first then trashed it.
First fix it twice, then trash it once.
Thanks for making this Paul! Thankfully I'm just dealing with one small line vertical line, but I may attack it this weekend! We shall see.
Me too... so‽
Did it work???
Hello Paul, great content. Since it seems that you know your fair share on the subject Im going to ask you. I have a Samsung TV that displays lines a short time after being turned on. If I turn it off and wait some time, when I turn it on it takes like 40 minutes or so for the lines to appear, and once the lines are there they get worse over time. This lead me to believe that this is a temperature related issue with the TCon board. Should I replace it or do you think that it is something else. I know that it isn’t the panel since the line positions and patterns aren’t always the same and sometimes they appear and sometimes they don’t. Thank you for your time and quality content.
I agree that it seems to be a temperature problem but I don't think it is with the T-Con board. I would guess that it is with the adhesive around the perimeter of the screen. Your panel is a matrix with horizontal and vertical lines like a window screen. The circuit strips are glued to this around the edges at the back. When the lines are visible try pressing on the strips until they go away. That would be the place where the glue is letting go. This would be the first thing I would try. Good luck.
Paul Pomerleau thanks, Ill try that before buying a new tcon. There is a detail I skipped in my description which is that if I switch inputs from HDMI to cable/air, the lines are not visible in cable. It is when the lines have gotten worse for continuous use that they appear on every source and not just on HDMI.
I have the same exact tv with lines a bit worse than that, but they come and go. My neighbor put it out on the curb and I took it in, hooked it up and the lines didn’t bother me. It was made in October 2010 and he’s had it when he moved into his house back in 2011. I have had it since June 2020. I don’t want to try to fix it because I use it on a daily basis. If it gets worse, I might try it.
I love this guy! Hey Google give me a full scan 😂 he needs his own show. The end was the best 😂 funny as fook
....perfect presentation......
Sorry sir how can't. Repairing this problem I have this plasma Samsung same this problem. Know that solutions
Great! Now all I need is Smart Home system with Google Assistant and I can start this repair.
I have had the same problem on my Samsung TV and fixed it. First remove the backing plate. Make a stand to hold the TV perpendicular to your table. Put a big mirror before the screen so that you can see the screen while you stands behind the TV. Turn on the TV. It is relatively safe if you keep your fingers away from the high voltage module. Touch every connector on the TFT controller and ALSO the connector on the panel. Finally you will see which connector is the most wanted one. I think the upper-middle connector for the panel is the one you are looking for. Good luck!
How did you fix it? Fixed the connector with tape?
@@vangelescu Clean the fingers with cotton buds and WD40 and then reposition the connector with hot glue.
Dar Hoo “fingers”?
@@vangelescu Gold plated tips on the connectors obviously.LOL
@@darhoo6470 loll... so my son hit out 65 incb samsung smart tv with a ball. And we are seeing those lines. Will fixing the connectors still fix the issue or are we screwed for good?
try cleaning the connector from the T-con board to the panel.
His reactions were like a low budget movie, was this even real😂😅😂😅
Google, where's the nearest landfill?
My tv go black so I turn mine off and turn it back on and it work but it do it again
That tv DOES NOT have a t-con board, that is a plasma tv. The board you are looking at is the logic board. LCD tv have timing control boards (t-con).
Yep... I second that - deffo a logic board!
Have the same issue but i discovered that the ribbon cable that connect matrix board on the lcd burnt out ...and I realy not sure if I can change that...
Paul, did you replace the Tcon board or panel?

By the way plasma TVs don't use tcon boards.
Its a Plasma tv not lcd,no TFT and no tcon board, It looks like tcon board but it is not. Called LOGIC BOARD in plasma tv. The problem of your tv is could be the X-BUFFER.
Right...
televizor samsung LE 32 D 559K the picture is doubled and has vertical bars on left side . can you help
Moisture on the frenel lens after sptray can do it. It may fry out but I think cleaners remove surface treatment.
Hahahaha I have to admit, you used google for everything else up to the "scan circuit', I had no idea what you may have had going on, but it was funny any way.. Good to see you thought, haven't seen anything for a while.. I mostly watch because of the Victory videos, but I enjoy all the stuff you do.. Keep on entertaining and training.. I would never have even tried what you just did, although it don't look very hard.. Funny thing is my dad was a TV repair man way back in the 60's.. Have a great day Paul...
I also had vertical lines in a Samsung TV Just running doing a complete setup of the TV - like when it was first put in operation solved the problem. Part of the set up is to have the TV re- scan for channels . Resulted in no more vertical lines. No dissemble of TV was needed.
Hi do you now if parts for smart Samsung are same as 8 year old Samsung cheers
I can't say for sure but I think they would not be compatible. Electronics changes a lot in 8 years.

yes cats can be fixed. However if you wait until they begin spraying they will continue to have the ability to spray.
Man !!
i thought that you'll fix it in the end .... huhh cool technician
😂😂😂😂😂😂
Tv's with a loud built in speakers has the potential to cause this kind of problem because of the vibrations, and LCD panels rely on a lot of contact points which is mostly secured by glue. I just avoid using built in speakers and isolate the speakers from the TV.
I like how you teach.
Bad panel you need to check the VGH and VGL signals and learn how to either tape up the signal to block the short in the panel or bypass the VGL from the drive board to the COF chips VGL with a insulated wire. Basically you got a short in the panel that needs connecting up. I got the same problem and bought a new T CON and the lines are still present. There's loads of tutorials on how to patch the panel up regarding those signals but it will mean removing the panel and doing some soldering.
Thanks for trying to fix it !
Paul did you ever fix the issue ?
Yeah, if you remove the back you will see all around the outside edge of the panel something called a COF (Chips on film) it is a flexible circuit board that is glued to the panel which is how it makes its electrical connections. The glue had let go in one area (apparently it is a common problem). To find it I turned on the tv and started pressing the film all around the panel until the lines went away. That was the spot where the glue let go. You can't re-glue it so I put a non-conductive wedge (I used plastic) against it so it will always be pressed at that spot while the cover is on and the lines stayed away. I ended up getting a new TV so I donated this one (and yes I did tell them about the mod). Anyway, this is how I got mine going again. It may not work for everyone but it did for me.
I have a Samsung QLED monitor for my Xbox Series X. I get vertical lines all over the screen on start up. After about 4 - 5 minutes, they disappear?? I've tried different HDMI cables to no effect. Any thoughts please?
You will have to take the back off the TV. Then around the outside edge of the screen there is a flexable circuit strip that is glued onto the contacts of the screen. This has probably let go in the area of there the lines are. With th TV on, press around the outside edge near the lines and see if they go away. Once you find the area you may have to wedge something in there to keep it constantly pressed and then put the back on. It will be difficult to reglue the circuit strip so wedging it is probably the easier way to do it. Hope this helps.
@@PaulPomerleau thanks Paul, I'll give it a try.
my hdmi ports werent working so i took out the board and baked it in the oven for 10 mins now it works. maybe try that with the tcon board because over time the solder loosens and reheating it mends it back together
Hey great tip, thanks for sharing. Glad you got yours working.

Would parts of a Samsung 40 inches, compatible with a 42 inches Samsung? (Chips or board)
Probably. Search for the board part number and it will tell you all the different TV's that it will work with.

Hey man I saw this video and I had a question first I want to tell you how the tv Got damaged this tv was shipped from another country at first nothing happened to the tv but after like 9 to 12 months the tv started showing lines and I have been using this tv for over a year before it was damaged and the tv is pretty Dusty too so please help me I don't wanna spent a fortune on fixing it

That's not an lcd tv it's a plasma tv try cleaning the buffer board connections on the bottom of tv
Thanks Paul.
I have a similar problem but I would have hoped by now Samsung would have posted a solution since many people are having similar problem. I have a TV repair shop and a background in electronics. An earlier post was spot on that the problem is either a high scan voltage or a low discharge voltage especially if the lines cover a range of tabs. There are adjustments that are possible for these voltages by changing the values for Ref resistors on the TCon board. You need a schematic for your particular model and don’t rule out the change in values for components of circuits shared across the problem coverage.
Was this a google sponsor ad? Lmao
I remove tcon pcb ribbon then turn on i have no picture but still have vertical lines so this means tcon pcb not fault. There is another pcb at top which i feel may be the power for leds.
This guy runs his whole house of off hey google. I love it
One of the circuit touched the ground of the display. You have to unscrew the board touched the ground and put a spacer in between the board.
You should check VGL voltage and ckv signal that might be short in side the panel just cut the signal ckv1 and ckvb1 and same 2 and three and then both cutted signal from panel side connect to the ground and check if ok or if not then try to connect with vgl that around -10 dc volt. Hope this solution work
Nice try with best efforts.
Hey google can you call for the service technician🤭🤭🤭
How about picture tube
You can use 91% isopropyl alcohol to clean the contacts as well right?
Yes you can use 91% but it would take longer to dry so make sure not to use the equipment for a while. 99.9% will dry the quickest.
@@PaulPomerleau Someone in my area selling a 55 inch tv for 100 dollars. It is a Samsung TV and it has the vertical lines, I tried to ask them the model number and they have not replied yet.
It turned out mine was the flexible ribbon circuit board that goes around the outside edge on the back of the screen. It is glued into place and some of the glue let go so the contacts disconnected. It is very difficult to re-glue it back on but if you can press all along the perimeter until the lines go away then find something non-conductive to put there that will hold it in place when the back is put back on, that should do it.
"Hey Google, add more likes and subscribers." Just kidding, good video.
LOL...when asked for more lights all 13 of my lights went full blast! Too MUCH...
I blew it with air on the little holes on the back and bam they were gone ...if tv by a window it pretty sure dirt..im on day 5 still working
What little holes on the back? Did you remove the back panel of the t.v. first?
Haha the ending was too funny!!!
Brutal honesty!
Tear a piece of playing card (may be fold it to make it thick) and put it between the plastic border and the screen panel where the line has appeared.
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!

@@PaulPomerleau Thx for the quick response Paul. Got it the day you posted but 4got to respond. Anyway, I had already tried that thoroughly with no success. I even tried it a second time as it seems the most likely culprit. Never once was there even a flicker. Since there is a missing (dead?) pixel, I am guessing that may be what caused it and that it is likely the panel. That would make it unfixable without replacing the panel. Really a shame. 60" set, less than 5 years old and really great picture. Ppl say it looks as good as my 4Ks. Thx again! I will probably throw it away and get another one.
How old was the tv when it started having issues?
About 10 years, that's why I thought it was caused by dirt. Turned out to be the ribbon cable around the perimeter of the screen became unglued.
