So I'm a former ET, and I had similar symptoms, and did a bit of these steps too, and had similar results, but didn't think to wedge pieces in. Not wanting to take the time (since I've got a toddler running around and my wife HATES when I start opening electronics up and she's stuck playing toddler ref), I took it to a pro.... Bad choice. They turned it on, decided the panel was bad and claimed I should buy a new one. I'm glad someone took the time to show this video and hope more folks see it.

This is a excellent video. He is ABSOLUTELY correct. I am a 40year + electronics technician. These TV's are easy to fix compared to what I repaired. I repair to the component level. I have replaced SMD IC chips ,etc. I am learning these new TVs and find videos like this to be very good. Nice job dude!
Thank you for the kind comments. The older TV in this video had florescent backlights. Here's a second video showing where similar symptoms on a newer TV with LED backlights was caused by something completely different: th-cam.com/video/raicZqT-qVo/w-d-xo.html Good luck. Thanks for commenting!
My TV sharp aquos 70 inches was showing a half black screen display and I found this channel and read through the comments below. I didn't want to take the tv off the wall and disassemble. I read one comment and it said to hit the tv top frame and the tv worked fine. Wow it fixed mine, too. I used a lint roller and tap tapped on top of the left side of the TV because the left side was black. So if you have the same problem try this! Hit the top of the TV. Good luck! 2022
Thanks a lot for your teaching. Though I'm not an electronics technician, now I'm learning about the inner parts of TV set. That is why I got trashpicked 46" & 48" LCD TV sets. These are under repairing in my hands. I'm not sure to fix it. Come to Korea and roll around some big apartment building. You can easily get several abandoned TV sets. Appreciate your easy speaking. I'm a deaf in English.
Great video. I was able to confirm this was the problem with my TV by simply squeezing the top of the TV frame. The picture was fine while I applied pressure and would come back when.i released it. Took it apart, located the ribbons and switched them and also cleaned with contact cleaner. Problem solved. Thank you very much
I watched your video but didn’t feel like taking the tv apart. Gave it a light tap on the right side about half way up, and it started working perfect again! Thanks anyway
There's a guy that fixed his by hitting it with a rolling pin. Short video but rather funny. Obviously loose cable but definitely a fix out of armageddon. "This is how we fix things in mother Russia" proceeds to beat the crap out of it.
Hi - how did you switch the positions of those two white cables? I am working on this repair myself but don't understand how to remove those cables from where they are and switch their positions as you did. Any help highly appreciated, thank you!
Ribbon cable connectors (female parts) are hinged at the top. Lift gently and they open same as the hood of an automobile. Once pressure has been released, some cables (male parts) are perfectly rectangular and will slide right out. Others are notched left and right so you have to lift slightly to get them above the notches before you can slide them out. Use your thumbnails and be gentle!
Need advice how to fix my tv which has sound and has picture some times but lately most of the time goes mostly black with bits of colour but no clear imageplease help me thanks
I have the exact same problem on a samsung ue50hu6900, It was working fine with 1 one whit dot in the middle, after regluing the diffuser that has fallen, the issue was there. Hopefully I understand english and came across you video. I know that one of these ribbon is slightly damaged, by my fault I guess. So I will swap them and see how it goes. Thank you for your video !
If it's just dark, but not blurry, then you may have a TV where the T-Con board is located at the bottom of the display panel assembly. That design suffers when glass cleaner sprayed onto the screen. It drips behind the bezel and corrodes the connectors. If that's what happened to your TV, cables can be cleaned with a soft, pink pencil eraser. Connectors can be cleaned with apple cider vinegar.
When i turn my tv on, there is like this black purple ish hazey patch covering about a 4th of the screen top to bottom. I reset the factory display settings and it turned to a white with purpleish hazy outline.
Hi Lawrence. Thanks for the Video. I have the same issue with a Samsung although not as severe. More like 1/4 the screen is ghosting / dark. If the exchange of ribbons do not work for whatever reason. Can you suggest another method? I saw one guy use duct tape holding a tooth tick down on the ribbon
Hey Lawrence I watched your video, really helpful, my problem is half my screen is dark the other half is normal. I tried cleaning the ribbon cables, then I switched them from either side, neither fixed the problem. It's still dark on the left side even after switching the cables . Do you have any advice for me? Or should I just get a new tv? It just started this morning while I was at work
The LCD TV shown in this video is an older florescent back lit model. Similar symptoms on a much newer LCD/LED back lit TV would more likely be caused by unlit LED strips inside the display panel assembly. Please watch "Insignia NS-55D550NA15 LED/LCD TV Repair" for details. Observe that the two display failures look nearly the same, but the causes are very different. Assuming yours is an LCD/LED TV, the next step would be to check the backlights. With most brands, there's no fire damage and you can fix the TV by identifying and replacing the burned out LED strips. If there are none, then you've got an internal failure in the LCD. Fixing that is another story, so please check the LEDs first. Good luck, and thanks for asking!
Just curious when the bottom part of the screen of an LG 60UJ6050-UA TV is very dim, not watchable, what steps would you take. A friend is willing to give me the set for free. TY for any advice.
You almost certainly have a bank of LED strips (maybe 4) out at the bottom of the display. The LG 60UJ6050-UA is a modern LCD/LED Smart TV (a $500 item) so the symptoms shown here on an older LCD/Florescent TV would not apply to it. The main thing to understand is that you describe a display panel problem, NOT a board problem. To fix it, you have disassemble the display, identify the strips (or just the individual LEDs) that have failed, read the part numbers off of them, order replacements from ShopJimmy or AliExpress, wait for them to come in, then install and reassemble. Watch the following LG TV repair videos for details: LG 50UH5500 UHD Smart TV Repair Secrets LG 42LN5700 - 47LN5400 LED TV Screen Repair Secrets Assuming you have the space to disassemble and spread out, and the patience and disposition it takes to accomplish this, you'll end up with a very nice TV for the cost of peanuts! And, if you replace entire strips (easiest way) you'll have spare parts (failed strips with many good individual LEDs) for next time. Good luck. Thanks for asking!
I got my 85 inch sharp tv exactly the same problem but left side is dark and blurry and right side is normal. I dont know if to open it or not its to big
Similar symptoms on a much newer 85" (LCD/LED?) TV would more likely be caused by open backlight strips inside the display panel assembly. Please watch "Insignia NS-55D550NA15 LED/LCD TV Repair" for details. If after watching "Insignia NS-55D550NA15 LED/LCD TV Repair," you decide to take your 85" screen apart, you'll need a second person to help you with disassembly. And, you'd best fabricate a stretcher to support the fragile LCD before lifting it, otherwise, even with two people on the job, the screen may flex and crack on removal. Thank you for asking!
Me too. Same tv i have my open right now. Same problem. Left side dark center blurry... right side Normal. Its more simple. On sharp everything is in the center no. Extra panel. To take of after. U take ba k part off i switched the same. Parts. To opposite side. Kinda worked. Its. Evenly blurry now lol right side still good. Idk im stuck. On what yo do iv cleaned everything. Wiggeled. Just about everything... Hate to pit it back togethere. Its taken up my whole bed lol..
No. The older LCD TV in this video has florescent tube backlights. Your 65" 4K TV almost certainly has LED backlights so it's far more likley to have the problem shown in this episode th-cam.com/video/raicZqT-qVo/w-d-xo.html titled LCD/LED TV Repair Secrets - Half of Display is Barely Visible. Good luck! Thanks for commenting.
Couldn’t you have then just left the piece of plastic wedged in on top of the ribbon connection and put it all back together for a real quick and easy fix?
I doubt the plastic wedge would have survived reassembly and transport. It almost certainly would have fallen out. Best to attempt a more permanent fix. Good luck, and thanks for commenting!
This video might have been recorded using an old JVC miniDVD camcorder. It broke right around that time. There are no parts available for that model and I've since stopped using it.
I have a Samsung TV and it doesn't have the thermal cable at the top (I believe it is an LED as well. . There are two that are located next to each other at the bottom in the middle. . I believe the darkness and the blurriness at the right was caused my a soccer ball that glanced off the television. I played with the cable as you did and nothing looked different.
Most likely the backside of the LCD cracked at the point of impact and that's what's causing your problem. To verify, you'd have to remove the bezel and rotate the screen 90 degrees. At one time, manufactures placed a sheet of heavy Plexiglas beneath LCDs to prevent them from flexing inwards. Today, there's just a very thin diffuser beneath the LCD offering no flex protection whatsoever. What you have described is a very common problem with Samsung UN series TVs.
I have a samsung UN75MU8000, while moving it downstairs and turned it on, the left side of the screen is dark. If what you’re saying is true about replacing the components won’t matter and if something you said cracked, is the TV just effed?
I had a samsung with this issue and found a burnt trace on the cof ribbon. I poked arounf a bit, it caught on fire and when the fire burned out the shorts were clear and the TV worked perfectly
Great work (except for catching things on fire)! For a flame proof example of the cut off method, please watch: th-cam.com/video/CFqSv3Rnk84/w-d-xo.html LCD/LED TV Repair Secrets - Backlights and Sound, but No Video. Thanks for commenting. Please like and subscribe as it really helps the channel.
Only the right side of the display is inverted, not the whole screen? I ask because inversion generally occurs when the TV is misdiagnosed and the main board is replaced. In some cases, it's necessary to toggle the inversion option in the service menu to reorient the display. Have you tried that? Regarding the dark and blurry problem, that's either the timing control board, the display panel assembly and/or the connections between them. As the Vizio M550NV uses LED back lights you might also have the problem shown here: th-cam.com/video/p_l_2My7IRU/w-d-xo.html.If visual inspection doesn't reveal any like that consider studying Kent Liew's screen panel repair eBook available from: www.lcdrepairguide.com. Good luck. Thanks for watching this video and thank you leaving a relevant comment.
@@LawrencePina Thanks for your reply. After doing a through visual inspection I discovered that I had somehow partially torn one of the ribbon cables that go from the led strip to the screen. When I press on the cable I get a very clear picture on the screen. I did some research and saw some videos where some guys used some silicone conductive compound thermal pads to fix the problem . This is only a project for me. I'm going to try the thermal pads and see what happens. What do you think?
Visit www.LCDRepairGuide.com. For screen problems not covered in this video, study "LCD/LED Screen Panel Repair" by Kent Liew. Generally speaking, when the backlights come ON and there's sound but no video (on either side of the screen), suspect a shorted LCD. What to do next: disconnect the FPC cables one at a time. If disconnecting one or the other gets half of the display back, then the cut off modification (described starting on page 78) should help you to restore the other side. And for what it's worth, if you can narrow the problem down to just one line, consider notching that line out of the FPC cable. Kent's book is written in Chinese English, so you may have to go over the material several times to grasp what he's saying, but the effort is well worth it. Good luck and thanks for commenting!
When the timing control board is located at the bottom, its ribbon cables are also at the bottom, and the connectors are often quite corroded from spray cleaners that drip onto them. The problem shown in the video is much more common when the Tcon is at the bottom. The source driver board will be at the lowest point and that's where you're likely to discover corrosion.
@@LawrencePina thank you for the reply. I can't see corrosion, but I did see one of your other comments to clean with apple cider vinegar. I'm going to try that. I've played with all the ribbons A LOT and have gotten no results. Exactly the same problem as in your video. So I'm not giving up. I see no visible damages either so it's really stumping me. Just going to clean the connections
@@AntoniYOwned As long as you have the TV apart, try swapping the cables, left to right. See if anything changes. It's a long shot, but sometimes, when there's visible corrosion, that's all you have to do. As you don't notice any corrosion, I'm thinking you may have a different problem. Watch the video titled "Insignia NS-55D550NA15 LED/LCD TV Repair." The symptoms in that video are similar but the cause is very different. Good luck. Thanks for watching.
The LCD TV in this video (manufactured prior to 2012) has florescent tube back lights. To view similar symptoms on a newer LCD/LED TV please watch "Insignia NS-55D550NA15 LED/LCD TV Repair" at th-cam.com/video/p_l_2My7IRU/w-d-xo.html If yours is an LCD/LED TV, it's much more likely that's your problem.
Had this same problem here but it's now also turning off after 6 seconds. Visually I see nothing wrong on the boards. In my case those cables at the top only disconnect on one end, but are soldered on at the other so I can't swap them :s
@@LawrencePina The issue with half screen being black for about 5 minutes after turning it on still remains, but it turns out it was only switching off cuz of a child lock. God only knows who activated that. I can deal with waiting 5 mins to get full picture, no problem.
I screwed around with all the cables multiple times added electric tape and cushen but the problems stays and i cant find the source aint these old lcd tvs just annoying
LG 32LB580B-SA is an LCD/LED television. As it's backlit with LEDs, not fluorescent tubes, one or more LEDs may have caught fire causing an open circuit to the right side of the screen. To see what that looks like, watch the video titled "Insignia NS-55D550NA15 LED/LCD TV Repair." So, now you know two things that might be causing the problem. Whichever it is, someone will have to take your TV apart to find out. Boa sorte!
Please indicate the make and model of your TV. If it's an edge-lit LCD/LED TV, not an LED TV with old-style florescent back lights (like the one shown here), and if it looks like the screen has been cut exactly in half (right down the middle), then most likely one of the two LED strips failed. Otherwise, you might have the problem shown in this video: Insignia NS-55D550NA15 LED/LCD TV Repair which you can watch at th-cam.com/video/p_l_2My7IRU/w-d-xo.html Good luck and thanks for asking!
I just replaced tcon picture was all jaxked half black white blurry image now picture is dark top half and bottom good with a few lines going threw middle
@@vinngrizzle What happens when you reinstall the original board? Do the original symptoms return? Do the new symptoms persist? Or, do you get a third set of symptoms? Assuming the replacement board is identical to the original, not an "also works in..." substitute, this should help you to figure out what's going on.
I have a question I dont know how to describe. like, when I stand up. it gets dark I have to sit down on a small chair to see. does anyone k ow what this is
Ours had this problem when you first turned it on. We'd just smack the back of the TV and it would work great. For years! Then one day, no matter how much we slapped the TV, it wouldn't get rid of the black haze. So I'm really grateful for this video. We already bought a new TV, but if I can tinker with - and FIX - the old one, we'll have one for another room, which is great!
Thank you for that i have a 60 inch sony bravia smart tv and it's doing the same thing it's showing light picture on the left side and dart on the right side
Leo, When the picture is light on one side and dark on the other but otherwise OK (not blurred or distorted and not an initial menu/setup/firmware problem) you can almost always correct it (permanently) by swapping the cables. Just reseating them may not be enough...
@@LawrencePina ok thank you i will try doing that like i say the tv showing the picture it just it show good on the left side and dart on the right side and when i tap on the right side of the out side of the frame of the tv the picture try to pop brite.
My samsung 55" had right side with a black screen on an angle I tried all the ribbon cable clean and swap and still the same. Prob a bad picture board..just gonna Junk it and NEVER buy another POS samsung TV as it's only 1.5 yrs old.
Based on my experience with similar size Samsung LCD/LED TVs, the symptoms you describe (half of the display is black and on an angle) suggest a shorted data line in the LCD panel, not a bad board. In that case, it might be very easy to fix. First, you need to to identify which of the two ribbon cables connecting the timing control board to the display panel assembly controls which side of the screen. Disconnect them one at a time to determine that. When the cable leading to the shorted side is disconnected, the other side should display perfectly. Next, you need to identify which signal line(s) on the disconnected side lead to the shorted data column(s). It's generally only one line. This procedure is easier shown in a video than described, but here goes: Fold a piece of 1/2" cellophane tape onto itself so that the sticky sides are stuck to each other. Starting from one side or the other, insert it into the open connector on the T-Con board so that it will keep 1/2" worth of lines from making contact. Reconnect the disconnected cable you identified, power up and see what happens, If there's no change or the display is worse, power down, move the cable over 1/2" and try again. At some point, the black half of the display will turn back on (believe me, it will), but it won't look very good. You're in the ballpark! Now you have to identify which of the insulated lines covered by the 1/2" of tape is causing the problem. Do that by powering down and carefully moving the insulator just one line at a time until the display turns black again. The line you just uncovered (just reconnected), is the line that's shorted. They're two fixes at this point. Some guys try to cut a really narrow sliver of tape and position it just right. I find it easier just to notch that line out of the ribbon cable. Now, the display might not look 100% perfect with one data line bypassed, but most people are not able to tell the difference. How long will this repair last? Well, the first time I fixed a TV having this problem was about 9 months ago. It's still working fine. The author of the ebook (www.lcdrepairguide.com/screen-repair/) I learned this procedure from, Kent Lieu, claims still no comebacks after 1 year. Other people, sharing their experiences at Jestine Yong's website (www.electronicsrepairfaq.com) have had similar success. Thing is, it doesn't cost anything, it's hard to understand but easy to do, and there's a high chance of success, so I hope you'll give this a try. Chances are you can have that TV fixed in no time! Good luck and thanks for commenting.
I remember the other tv was a isis tv and I turned it on and it went boom so anyone out the avoid isis TV UNLESS YOU WHAT A BOOM BOX GET IT BUT REALLY DONT BUY THEM
Apparently the point went over your head: New boards are not going to fix screen problems. How could you possibly have watched the video and not understood that?
the point is .!! the ribbons or the connector are the cause of half black screen . i just tested and confirm this on hissen tv screen . * thanks for uploading the video ! lawrence

If it's just dark, but not blurry, then you may have a TV where the T-Con board is located at the bottom of the display panel assembly. That design suffers when glass cleaner sprayed onto the screen. It drips behind the bezel and corrodes the connectors. If that's what happened to your TV, cables can be cleaned with a soft, pink pencil eraser. Connectors can be cleaned with apple cider vinegar.

Your 65" 4K TV almost certainly has LED backlights so it's far more likley to have the problem shown in this episode th-cam.com/video/raicZqT-qVo/w-d-xo.html titled LCD/LED TV Repair Secrets - Half of Display is Barely Visible. Good luck! Thanks for commenting.
it really effen worked! Thanks!

@@davidwilcox8604 sir, you really hit it hard with a rolling pin and freakin' fixed the problem XD oh deymn XD haha
Mate, it's those micro ferrets at it again 😂
I have a jvc flat screen tv with the right side darker than the left.... Would replacing the t-con board work?
Not in my experience!
Couldn’t you have then just left the piece of plastic wedged in on top of the ribbon connection and put it all back together for a real quick and easy fix?
I doubt the plastic wedge would have survived reassembly and transport. It almost certainly would have fallen out. Best to attempt a more permanent fix. Good luck, and thanks for commenting!
@@LawrencePina ahh yea you are right it probably wouldn’t stay put. Very smart trick to troubleshoot tho thanks for the info!
I replaced T-con board to fix solarization but now I half of the screen is double (so looks like three images (split down the screen)
Are you recording with a Nokia 3310?
This video might have been recorded using an old JVC miniDVD camcorder. It broke right around that time. There are no parts available for that model and I've since stopped using it.
I have a Samsung TV and it doesn't have the thermal cable at the top (I believe it is an LED as well. . There are two that are located next to each other at the bottom in the middle. . I believe the darkness and the blurriness at the right was caused my a soccer ball that glanced off the television. I played with the cable as you did and nothing looked different.
Most likely the backside of the LCD cracked at the point of impact and that's what's causing your problem. To verify, you'd have to remove the bezel and rotate the screen 90 degrees. At one time, manufactures placed a sheet of heavy Plexiglas beneath LCDs to prevent them from flexing inwards. Today, there's just a very thin diffuser beneath the LCD offering no flex protection whatsoever. What you have described is a very common problem with Samsung UN series TVs.
I have a samsung UN75MU8000, while moving it downstairs and turned it on, the left side of the screen is dark. If what you’re saying is true about replacing the components won’t matter and if something you said cracked, is the TV just effed?
I had a samsung with this issue and found a burnt trace on the cof ribbon. I poked arounf a bit, it caught on fire and when the fire burned out the shorts were clear and the TV worked perfectly
Great work (except for catching things on fire)! For a flame proof example of the cut off method, please watch: th-cam.com/video/CFqSv3Rnk84/w-d-xo.html LCD/LED TV Repair Secrets - Backlights and Sound, but No Video. Thanks for commenting. Please like and subscribe as it really helps the channel.
Dude I don't know what's causing it! That is why I am here lol
I have a Vizio M550NV. The right have of the screen is dark an inverted. Any suggestions?
Only the right side of the display is inverted, not the whole screen? I ask because inversion generally occurs when the TV is misdiagnosed and the main board is replaced. In some cases, it's necessary to toggle the inversion option in the service menu to reorient the display. Have you tried that? Regarding the dark and blurry problem, that's either the timing control board, the display panel assembly and/or the connections between them. As the Vizio M550NV uses LED back lights you might also have the problem shown here: th-cam.com/video/p_l_2My7IRU/w-d-xo.html.If visual inspection doesn't reveal any like that consider studying Kent Liew's screen panel repair eBook available from: www.lcdrepairguide.com. Good luck. Thanks for watching this video and thank you leaving a relevant comment.
@@LawrencePina Thanks for your reply. After doing a through visual inspection I discovered that I had somehow partially torn one of the ribbon cables that go from the led strip to the screen. When I press on the cable I get a very clear picture on the screen. I did some research and saw some videos where some guys used some silicone conductive compound thermal pads to fix the problem . This is only a project for me. I'm going to try the thermal pads and see what happens. What do you think?
DALLO NELSON anything beats a blank, I always say😊
Sir tcl ledtv L55d backlight ok no picture any suggestions please
Visit www.LCDRepairGuide.com. For screen problems not covered in this video, study "LCD/LED Screen Panel Repair" by Kent Liew. Generally speaking, when the backlights come ON and there's sound but no video (on either side of the screen), suspect a shorted LCD. What to do next: disconnect the FPC cables one at a time. If disconnecting one or the other gets half of the display back, then the cut off modification (described starting on page 78) should help you to restore the other side. And for what it's worth, if you can narrow the problem down to just one line, consider notching that line out of the FPC cable. Kent's book is written in Chinese English, so you may have to go over the material several times to grasp what he's saying, but the effort is well worth it. Good luck and thanks for commenting!
So my Tcon board is at the bottom, so my ribbons are also down there, right? Every video I see, people have theirs at the top
When the timing control board is located at the bottom, its ribbon cables are also at the bottom, and the connectors are often quite corroded from spray cleaners that drip onto them. The problem shown in the video is much more common when the Tcon is at the bottom. The source driver board will be at the lowest point and that's where you're likely to discover corrosion.
@@LawrencePina thank you for the reply. I can't see corrosion, but I did see one of your other comments to clean with apple cider vinegar. I'm going to try that.
I've played with all the ribbons A LOT and have gotten no results. Exactly the same problem as in your video. So I'm not giving up. I see no visible damages either so it's really stumping me. Just going to clean the connections
@@AntoniYOwned As long as you have the TV apart, try swapping the cables, left to right. See if anything changes. It's a long shot, but sometimes, when there's visible corrosion, that's all you have to do. As you don't notice any corrosion, I'm thinking you may have a different problem. Watch the video titled "Insignia NS-55D550NA15 LED/LCD TV Repair." The symptoms in that video are similar but the cause is very different. Good luck. Thanks for watching.
Thank you very much!
In my case its my laptop screen, what can i do?
I have the same problem with my LCD TV and this looks really helpful. Has anyone tried this, reply below ?
The LCD TV in this video (manufactured prior to 2012) has florescent tube back lights. To view similar symptoms on a newer LCD/LED TV please watch "Insignia NS-55D550NA15 LED/LCD TV Repair" at th-cam.com/video/p_l_2My7IRU/w-d-xo.html If yours is an LCD/LED TV, it's much more likely that's your problem.
Is that a Dance TV mine look just like it
I have that dark shadow at the top of my screen it gose away but comes back when I trun on and of it eventually go away then come back
Had this same problem here but it's now also turning off after 6 seconds. Visually I see nothing wrong on the boards.
In my case those cables at the top only disconnect on one end, but are soldered on at the other so I can't swap them :s
If yours is an LED/LCD TV, then you may have the problem shown in "Insignia NS-55D550NA15 LED/LCD TV Repair." Hopefully, yours won't be that bad...
@@LawrencePina The issue with half screen being black for about 5 minutes after turning it on still remains, but it turns out it was only switching off cuz of a child lock. God only knows who activated that. I can deal with waiting 5 mins to get full picture, no problem.
Surely removing the back cover would void the warranty.
Not an issue with this old TV as the warranty had expired years ago.
I screwed around with all the cables multiple times added electric tape and cushen but the problems stays and i cant find the source aint these old lcd tvs just annoying
I have this LG tv that the model is a 32LB580B-SA and the righ side of the tv is dark, pls help
LG 32LB580B-SA is an LCD/LED television. As it's backlit with LEDs, not fluorescent tubes, one or more LEDs may have caught fire causing an open circuit to the right side of the screen. To see what that looks like, watch the video titled "Insignia NS-55D550NA15 LED/LCD TV Repair." So, now you know two things that might be causing the problem. Whichever it is, someone will have to take your TV apart to find out. Boa sorte!
@@LawrencePina aw man, thanks anyways
Can you help me please it has already been 2 hours till half of the screen became dark
Please indicate the make and model of your TV. If it's an edge-lit LCD/LED TV, not an LED TV with old-style florescent back lights (like the one shown here), and if it looks like the screen has been cut exactly in half (right down the middle), then most likely one of the two LED strips failed. Otherwise, you might have the problem shown in this video: Insignia NS-55D550NA15 LED/LCD TV Repair which you can watch at th-cam.com/video/p_l_2My7IRU/w-d-xo.html Good luck and thanks for asking!
Thank you! Thank you! Thank you! Thank you! Thank you! Thank you! Thank you!!!!!!!!!! You're the F@#KiN' man!!!
I just replaced tcon picture was all jaxked half black white blurry image now picture is dark top half and bottom good with a few lines going threw middle
T-Con board is not usually the cause of this problem. Wasn't that the whole point of the video?
@@LawrencePina actually tge tcon fixed my issue but now dark top half of screen
@@vinngrizzle What happens when you reinstall the original board? Do the original symptoms return? Do the new symptoms persist? Or, do you get a third set of symptoms? Assuming the replacement board is identical to the original, not an "also works in..." substitute, this should help you to figure out what's going on.
Thinking tcon was bad now need to check leds
I have a question I dont know how to describe. like, when I stand up. it gets dark I have to sit down on a small chair to see. does anyone k ow what this is
Could you please indicate the make and model of your TV?
@@LawrencePina r/whoosh
while he is quizzing is that what is causing it ... I want to smash the TV with a massive mallet
But it's such an easy fix!
Mine went like this for 10 mins then i unplugged an put it back on an was fine
Ours had this problem when you first turned it on. We'd just smack the back of the TV and it would work great. For years! Then one day, no matter how much we slapped the TV, it wouldn't get rid of the black haze. So I'm really grateful for this video. We already bought a new TV, but if I can tinker with - and FIX - the old one, we'll have one for another room, which is great!
Is that what's causing it? ok I'm done
Its the only thing about these tvs they were built so they dint last long so you'd spend money buying a new one there a con
Make a video on how to fix a camera while recording videos on how to repair your tv
down side half disply
Thank you for that i have a 60 inch sony bravia smart tv and it's doing the same thing it's showing light picture on the left side and dart on the right side
Leo, When the picture is light on one side and dark on the other but otherwise OK (not blurred or distorted and not an initial menu/setup/firmware problem) you can almost always correct it (permanently) by swapping the cables. Just reseating them may not be enough...
@@LawrencePina ok thank you i will try doing that like i say the tv showing the picture it just it show good on the left side and dart on the right side and when i tap on the right side of the out side of the frame of the tv the picture try to pop brite.
@@mrblack7606 bright?
@@LawrencePina Do you have any recommendations as to where I can purchase replacement ribbon cables?
👍👍👍👍👍👍👍👍👍
My samsung 55" had right side with a black screen on an angle I tried all the ribbon cable clean and swap and still the same. Prob a bad picture board..just gonna Junk it and NEVER buy another POS samsung TV as it's only 1.5 yrs old.
Based on my experience with similar size Samsung LCD/LED TVs, the symptoms you describe (half of the display is black and on an angle) suggest a shorted data line in the LCD panel, not a bad board.
In that case, it might be very easy to fix.
First, you need to to identify which of the two ribbon cables connecting the timing control board to the display panel assembly controls which side of the screen. Disconnect them one at a time to determine that. When the cable leading to the shorted side is disconnected, the other side should display perfectly.
Next, you need to identify which signal line(s) on the disconnected side lead to the shorted data column(s). It's generally only one line. This procedure is easier shown in a video than described, but here goes:
Fold a piece of 1/2" cellophane tape onto itself so that the sticky sides are stuck to each other. Starting from one side or the other, insert it into the open connector on the T-Con board so that it will keep 1/2" worth of lines from making contact. Reconnect the disconnected cable you identified, power up and see what happens, If there's no change or the display is worse, power down, move the cable over 1/2" and try again. At some point, the black half of the display will turn back on (believe me, it will), but it won't look very good. You're in the ballpark! Now you have to identify which of the insulated lines covered by the 1/2" of tape is causing the problem. Do that by powering down and carefully moving the insulator just one line at a time until the display turns black again. The line you just uncovered (just reconnected), is the line that's shorted.
They're two fixes at this point. Some guys try to cut a really narrow sliver of tape and position it just right. I find it easier just to notch that line out of the ribbon cable. Now, the display might not look 100% perfect with one data line bypassed, but most people are not able to tell the difference.
How long will this repair last? Well, the first time I fixed a TV having this problem was about 9 months ago. It's still working fine. The author of the ebook (www.lcdrepairguide.com/screen-repair/) I learned this procedure from, Kent Lieu, claims still no comebacks after 1 year. Other people, sharing their experiences at Jestine Yong's website (www.electronicsrepairfaq.com) have had similar success.
Thing is, it doesn't cost anything, it's hard to understand but easy to do, and there's a high chance of success, so I hope you'll give this a try. Chances are you can have that TV fixed in no time! Good luck and thanks for commenting.
👍👍👍
I did it and it didnt work
Mine is on the bottom of screen.
Mine too and i can't find the fix.
Stupid ribbon cables. I have a new nemesis.
some dora explorer questions
I remember the other tv was a isis tv and I turned it on and it went boom so anyone out the avoid isis TV UNLESS YOU WHAT A BOOM BOX GET IT BUT REALLY DONT BUY THEM
Fix up your cam
Get to the point
Apparently the point went over your head: New boards are not going to fix screen problems. How could you possibly have watched the video and not understood that?
the point is .!!
the ribbons or the connector are the cause of half black screen .
i just tested and confirm this on hissen tv screen .
