Samsung TV Vertical Lines 

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 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!

For me it doesn't matter whether it worked or not,the video was educative and worthwhile. Thank you

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!

Hey Google, gimme back my 7 minutes....

Hey google - fix the tv.

Not sure why you are getting hate. It was entertaining (well, as entertaining as this kind of video can possibly get) and honest.

This didnt help me in any way by my problem with my gaming monitor but I got entertained so, thumbs up ! 👍🏻 greetings from germany

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.

Hey 2021!! This really helped me ! I fixed all the lines on my tv ❤️❤️❤️❤️

You drove my Google device crazy in your video.

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).

Hey Google remove the lines 🤣🤣😂😂

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 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!

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!!!

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 🤣

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.

Hey Paul... You are a good teacher...

My google assistant activated everytime you sent a command. Lol

great video paul ! i have one thin yellow line on 1 month old samsung 55" . i love taking things apart&back again. glad i watched till the end. i was about to tell my wife let's lay the tv on the table ...hahaaa

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.

Did you actually say "Thank You" to Google assistant ?

Haha the ending was too funny!!! Brutal honesty!

Remember !? Tony stark summoning Jarvis ...Casually...

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?

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.

Thank You, Paul. This video helped me to fix my television. I appreciate the time you put into making this.

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.

Nice demonstration of 'hey google', thumbs up sir.

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

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.

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.

try cleaning the connector from the T-con board to the panel.

I love this guy! Hey Google give me a full scan 😂 he needs his own show. The end was the best 😂 funny as fook

His reactions were like a low budget movie, was this even real😂😅😂😅

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.

Great! Now all I need is Smart Home system with Google Assistant and I can start this repair.

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.

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.

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).

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.

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.

As you know, swelling caps can shift frequencies of operation. A quick inspect of the tops of all the electrolytic caps may lead to a quick fix.

Good Video- I had a feeling that it wasn't going to work also but I picked up some tips-thanks Paul

Moisture on the frenel lens after sptray can do it. It may fry out but I think cleaners remove surface treatment.

Google, where's the nearest landfill?

You might want to try unplugging the cables that go from the T-CON to the LCD driver boards. You can then turn on the TV and see if the lines are still there. That will give you a good idea if the T-CON is bad or the panel. You can also run the TV with only one of the cables plugged in. Finally, you can gentle push on the FPC cables that go from the driver boards (the long boards that the T-CON connects to) to the panel itself while the TV is on and see if the lines disappear. The cables deal with the section of the TV that is around the cable. For example, with your TV in this video, it would be the middle cables. If that fixes it, sometimes, you can wedge something like foam between those cables and the bezel.

Paul, try the solution of Video ID "oVnGjwxF3MM": on the other side of flat cable, on display connectors, install that thick foam tapes that will softly press them).

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...

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

I just watched this today and i have the same tv i did exactly what u said but i had way more lines and i fixed it on god

Ka galing ni Goooogleeee eh🥰

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.

By the way plasma TVs don't use tcon boards.

LOL...when asked for more lights all 13 of my lights went full blast! Too MUCH...

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.

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.

ngl i would die for this man

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.

I just punched my tv and it's fixed. Old school works all the time

....perfect presentation......

Man !! i thought that you'll fix it in the end .... huhh cool technician

Stop saying Hi Google... You're messing up with my living room

“Hey Google” Turn the gas on 1am

He tryna flex his ps3

"Hey Google, add more likes and subscribers." Just kidding, good video.

Was this a google sponsor ad? Lmao

Wow....I just want to hang out and drink beer with you, bro.

This guy runs his whole house of off hey google. I love it

the problems usually in one of the transistors you have to check them and the small capacitors

Paul: Hey Google, when did I make my last video? Google: You mean the video where you tried to fix the toaster but failed? That was 48 days ago.

My advice. Toss it and get in line on black Friday.

My home assistant going crazy during this video lol

Hey google can you call for the service technician🤭🤭🤭

I've got a cheap Chinese 1080p LED TV worked for around 5month and I can tell you it was in perfect condition when the lines started to appear so In conclusion it's the cheap materials who made the problem occurre

Thanks for trying to fix it !

Hey Google, go grab me a Beer?! Ok, Hey Google, now go grab me a bat so I could blast the #### out of this TV 📺! And hey Google, while you’re at it, go grab me a second beer, on the double!

I like how you teach.

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.

Need to pull down to the panel Layers where the ribbon feeds in. Wedge glued connectors to a tight fit. Takes a long time.

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

Great video! Came here with the same problem! Gonna give this a try! Hopefully I get lucky 🤣. What did you end up doing btw? Did you get a new tcon board or a new TV?

My tv go black so I turn mine off and turn it back on and it work but it do it again

Nice try with best efforts.

Sorry sir how can't. Repairing this problem I have this plasma Samsung same this problem. Know that solutions

Paul, did you replace the Tcon board or panel?

He was able to command Google the Automation, I hoped Google could also able to remove the screw by Google Voice Command and other actions in freehand without any human physical intervention by hand! 😁😁😁😁😁

My Samsung 60" flat screen has a vertical 4" wide pixilation band. The strange thing is....it goes away for awhile and then it comes back. Its definitely the tv and not the Comcast cable source. I was with Samsung Tech Support for 45 minutes...only to be told to call a technician.

This guy is like watching Tony Stark and JARVIS work

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?

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.

Squeeze with your fingers (hard) the bezel edges all around until you find the sweet spot . I know that sounds like it couldn't possibly work. Don't knock it till you try it.

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

So are we just gonna ignore the fact this guy goes full on Tony Stark with his Google device?

YOU ARE GREAT SIR !

First remove the backlight voltage and try to put light on the panel, if you see the lines again then maybe is the panel if you don't see the live then it's the t-con board. Then try to put out the t-con board and soldering the pins around the chipset (most the voltage chipset not the cpu, big own), plug in and open TV and see if you have the same lines, after this try to reflow all the board and put it back again and see what happend. Because is color lines for my expirience i think is the t-con board 99%. When the panel is damage the lines are Black not color.

You will need check panel contact with P-address buffer board (bottom board in TV)

Hi do you now if parts for smart Samsung are same as 8 year old Samsung cheers
