[@kylenickels973]

@@FrugalRepair my issue is from top to bottom on the right hand side of the screen, about 5 inches wide. Every so often it'll flicker black and white horizontal lines. The TCon board is built into the mainboard. Ive tried 4 new boards and 2 new PSU. If I change the ribbon cables the issue will switch from the left to the right side of the screen. 1 long and 1 short cable the problem will be on both sides. 2 short cables it only happens on the right. Its very intermittent.

I bought an LG cinema 3d TV for $50 at a thrift store. It was made in 2013. It was brought in because, although it worked OK, it had some fine horizontal lines on the left of the screen. Before purchasing it, I remembered something about the problem from a You Tube video I saw a while back (Your one!). I took a chance, brought it home, reviewed your video again, used the trial and error technique to identify the problem lines, taped 'em up and BAM, the lines are now gone! The picture is now perfect. I can enjoy my 3d movies again. Thank you so much!

[@anjalymeldhose]

Amazing!!! Really..I have a two year old IFFALCON LED TV 55inch. All of a sudden it started having horizontal moving lines. As usual I called the customer care and a service tech visited my home. He said the panel is gone.Replacing it will cost about 85% of new tv cost. That's when I found your video and thought will give a try. I don't understand electronics or anything. I couldn't read whatever is written on the board.I tried the try and error and VOILA!! My tv is now working. There are few black lines in bottom left. But I don't mind those few lines in such a big tv.Even 4k looks good only. So thankyou sooooo much.

[@DIYDaveOK]

I just fixed a three-year-old Vizio M558-G1 by applying the opposite logic on the image vs control lines. Vertical lines dominated the picture, and removing the TCON cables revealed the problem to be on the left-hand side. From your video, wherein you pointed out image data is vertical and control/timing data is horizontal, that told me I had an image information issue. Before then, I had no idea which pins to cover. That data limited the shorted vertical image processor to one of six on the right and I inferred that meant six control lines. Covered them all, and the picture came back immediately with a shadow in the lower left corner. I then started working one at a time, starting with line 6, then 5, and *bingo*, the picture was back with no flutter. I put it back together and it has been running perfectly for about four hours now. You just saved me $1,600 I was getting ready to plunk down on an LG G2!! ❤️

[@rickdelpino472]

You’re explaining this more in depth!!!! Thanks!!! But I would really really want to repair the clock signal...I love too much my TV and want to learn more about replacement components.

[@FrugalRepair]

Thanks! My guess is that the problem is somewhere embedded in the panel. Maybe with the right tools you could get in there without damaging the panel. It would be tricky though. I would like to have a full schematic of the panel, that might help to pinpoint where the issue is.

[@Pfirtzer]

@@FrugalRepair I saw some guys on YT repaired it by cutting the connection on the board it self instead of using tape. I have a Samsung I got for free a 42'' inch or so, bought a Panasonic for 60 euro's a good one and 12 euro's for the remote. I have the feeling older tv's lasted much longer than the flatscreen do, they are just a throw it away.

WORKED!!! Thank you so much. I had a 58 inch Hitachi tv that had a suspected bad tcon board. Then my kitchen JVC Fire Tv panel board packed up. Not worth fixing the JVC but I used the Tcon out of the JVC as it was the same part number and make but version 4 rather than version 1 that was already in the Hitachi. Then it all loaded up (it had been dead in the garage for two years!) but it had the horizontal lines. Took off each cable and figured it was the right side. First attempt of tape in the middle didn’t work but moved it right a bit and second try worked! It’s not 100% but it’s 99.99%! Now I have a very happy wife as she can watch Strictly in the kitchen.

Bro, this basically fixed our TV. We taped over the left-most 4 pins on the left side ribbon (looking at the back of the TV, oriented right side up). The only down side is that it seems the red LEDs are affected by this. There are horizontal wavy patterns every time a lot of red is shown on the screen (like in Netflix, for example). Either way, our TV literally randomly started showing lines and color stains, and this helped us completely get rid of those, so our TV is watchable once again. Thank you so much, dude!!!

Any suggestions would be awesome, thank you.

[@FrugalRepair]

Good to hear you got the link. What you are describing sounds like there is at least one shorted LED module on the darker side. The reason you get full brightness at boot up is that the power supply ramps up the voltage all the way and then the short circuit happens to take it out some others LEDs (maybe it's localized to one of the LED strips).

Congratulations on the repair. Not sure about the line, likely it’s part of the internal lcd issue your screen is having. You might be able to minimize it with blocking a different row signal. But if you’ve tried all of the combinations then that may be the best you can get.

[@Kurtis761]

I've fixed 4 different models of LCD tv's with one simple solution. Remove the back cover of the tv, take a good can of compressed air, and blow out as much of the dust as possible. Make sure to concentrate around all the capacitors. And I'll guarantee you 80% of the time, this will fix your issue and the lines will disappear. So try this fix before contacting a repair centre, or even replacing the tv.

If you haven’t already, it might be helpful to download my PDF, I have some diagnostic steps in there.

[@Bada4ever]

If you use trial and error again, like you did in another of your videos, could you find which exact line or lines were causing the malfunction? Therefore, wouldn't less tape blockage boost the signal by chance? Thanks again for your content! I'm trying to fix horizontal lines on a TV given to me.

[@FrugalRepair]

Finding the exact cause can be tricky because it is likely something not visible (or accessible) inside the lcd assembly. So you need to do trial and error diagnostics from the outside (ie mess with the row signals) to try to narrow it down. The row signals are individual so there isn't a boost, per se. It's a bit complicated to explain but that's what I was hoping to do in this video, lol.

[@FrugalRepair]

Thanks. That’s great that you like fixing electronics! What have you been working on lately?

@@FrugalRepair My Vizio SmartTV has horizontal, fuzzy lines but it has a vertical roll as well. So this may not do the trick but I thought I'd try your trick with the tape (maybe need to block some of the Vertical connections as well?)..... I would take apart Halloween and Christmas decorations as a kid to get the motion sensor or lights to work again. Most of the time just taking connections apart and putting back together did the trick. And I fix cell phones here and there. But I love taking apart electronics to diagnose and fix them. I never knew how the pixels in an LCD worked, so cool to have someone explain it other than, "It's magic" (What my electronics engineering teacher told me about how radio signals work). Needless to say, I did not care for that teacher. Thanks again

[@ChristopherFiola]

Thanks for the hack! This did fix an horizontal line I had on my 4k TV. Only issue is afterwards I get some faint horizontal lines across but not very noticeable. For the tape I winged it and guessed right by trial and error and it seemed to do the trick!

[@FrugalRepair]

Awesome! Congrats.

Thank you @FrugalRepair! Very informative video and well explained. Now I have Philips TV (58PUS7855/12), and after taking a hit from the tennis ball by our youngest the horizontal lines appeard plus on the right side of the display around 8 inches from the bottom the screen is getting really hot so it started to melt the display and the plastic casing. Now I unplugged the ribbons from T-CON from both sides and indeed with ribbon for right side unplugged (S-L, left from the rear of the screen) the right side of the display is white and right side displays image with plethora of horizontal white lines. When I unplug ribbon for left side of the display the left side is white and right side displays better picture(still horizontal lines) and no image displayed from the bottom up to around 8 inches. This is where the ball hit the screen (I believe) and now very hot place (short) can be found on the edge of the display. Not sure how to proceed further. Much appreciated for any suggestions. Thanks!

[@FrugalRepair]

Sounds like the lcd cracked when the ball hit it. If so, you unfortunately, aren't able to repair the cracked screen.

@@FrugalRepair Thanks. What a bummer:). I was trying some more info. Stumbled upon info that using jest gun can help to return crystal to its compartments, but this probably pure luck:). It seems like liquid crystal spilled over the area and/or paths damaged causing short. Would send a photo here but it doesn’t let me. Wanted to give it a go before I let it go:). Cheers

[@dans9953]

Can still watch the TV and funnily it would be okish after a while but then can freeze and getting darker like image is stopped being fed to display at all. Trying to find some patents and not there yet, found Ambilight though:). The manufacturer is TPV who supposedly can use brand name Philips.

I definitely just started covering and uncovering lines on the board until i got a good picture and it worked lol 😂 thanks ! Merry Christmas!

[@edpax14]

You're a legend! thanks for sharing your knowledge. Question: can you change a broken LCD panel from a different brand or model? Is that possible?

[@FrugalRepair]

Thanks! Yes you can replace an LCD on the TV, but the issue is that it has to match what the timing control board is outputting. That is, all of the signals must match on both sides.

[@VALIANT_Electronics]

Yes you can, you need to check that vcc is the same, also, if the screen has an lvds cable or ribbon cable you need to check if they are the same kind, for example there are screens that are milimetrical so they have only one ribbon cable to the tcon this cable had like 50 lvds line or more, also you need to check if the screen had the same ratio, you cant replace a 60hz screen with a 120hz screen unless you have a converter, also they need to be same size, inches are not standar for every screen, you can have two 42" screens but one can be 2 or 3 milimiter bigger. Sony is compatible with samsung and lg is with any chinese screen

[@thulanisibanda5562]

Managed to fix my TV today. Thank you so much!

[@FrugalRepair]

Congratulations!

[@wetytbub]

Good job!Looking forward to a video, where you talk also about vertical lines issues and possible fixes.

[@FrugalRepair]

Thanks! I do have a TV that has vertical lines so maybe I will make a video sometime. Great suggestion. The jerry rig solution many times for that is to put non-conductive material on top of one of the electrical connections and force it down by screwing the frame down on it to create pressure on it.

Hi, I have been checking out your videos and thanks for sharing the quick diagnostic tips. I have an issue and still cannot locate the problem. My issue is the screen goes dark between 6-12 minutes with no noticeable lines on the screen and I have already tried swapping the t-con board. I went as far as outline the front screen off to check the LEDs and they function so I am starting to hit a wall and if you have any other suggestions I would love to hear them!

[@FrugalRepair]

Sounds heat related to me. Did you try turning the brightness down to 10% and see if it lasts longer? Or even put a fan on the vents of the tv to keep it cool?

Hey Rhys.. I have a question.. When you do a continuity test on the signal lines, cant that damage the sub pixels ? I am not sure what the average multimeter puts out for a continuity test or what voltage the sub pixels are running at so could the meter output cause secondary damage ?.

[@LuisMendez-nz2bn]

Have a Samsung UN55NU7100FXZA Model that kept recycling on and off. The standby LED would blink twice before it recycles again. This method you describe also worked to resolve this issue...It was also the screen on this model that was causing this issue. Thanks for sharing your knowledge.

Hi Reese. Thanks for sharing such valuable insights with us! I have an issue with my LCD where I see horizontal waves. They're moving continuously from bottom to top and are particularly noticeable with dark backgrounds. Do you have an idea of what the issue might be?

[@FrugalRepair]

I’d try the diagnosis in these videos. You’d want to isolate if the issue is in the lcd panel or on the tcon

[@pilotgundul]

Good luck! Biggest thing is not to put pressure on the lcd screen so it doesn’t crack. And always make sure the power is off while you are directly working on it.

[@rustymit6399]

Thanks so much for being here. I have collected all the things I need but am stumped at locating the clock pins. I’m working with a Sony tv and the board is an le650aqp. Is there a certain page or specific language to use to find which pins on the board are the clk’s. Thanks in advance for any help you can provide.

[@FrugalRepair]

You can use a multimeter in continuity setting to find pins that are electrically connected on both sides. Look for a group of them in a row and that’s probably them

[@rustymit6399]

Thanks so much, I’ll do that.

[@rustymit6399]

Good morning, I’m still having a problem finding the clk pins. The t con board has 4 ribbons and I’m not sure which set to use. Any suggestions?

[@sunilashok2902]

First I would like to thank you for the simple and excellent explanation.I have a Panasonic Fhd tv which started showing the horizontal lines. I opened it and found the t con board which was surprisingly an lg board ,identified that the left half was the reason for the horizontal lines and the tape actually fixed it. I have a question though where actually is the problem,is it the led panel or the t con board ?
