@@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 have lines that are almost transparent and move do you know how to fix this lg phone screen problem

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!

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!! ❤️

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).

Hi Sir, I am Rao from India. I did as you described and solved the issue of horizontal lines. Thank you 😊.

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

Жыл бұрын

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.

Thank you for making this wonderful video that plainly explain how a LCD monitor works. I enjoyed watching both parts. I repaired a few monitors in the past simply by replacing components without fully understanding how the monitor performed the signal processing part. I guessed my luck ran out when I got a panel displayed everything in BGR instead of RGB while appeared to be intact. I have been stumped for awhile trying to look for known cases with similar issues, but I think I didn't even know how to ask the right questions. It's nice to finally know what to look for!

Thanks!

Thanks it’s really interesting , also got problems with T-con board the tv was turned black white. I replaced the all board bc the chip only wasn’t available ... Anyway think the board is fixable, the LCD himself probably doesn’t have problems.

Thanks! I hope you can figure it out.

Thanks for the explanation. I “fixed” mine a number of years ago and couldn’t understand why it worked.

You used the blocking method on the row signals?

Frugal Repair - I watch tons of your videos just because I like to learn stuff like this in case I ever need to know it. Haha. You have a great way of explaining things, and keeping the videos super interesting. (Especially with the extreme close-up footage, and heat tracking elements). However!! I need your help, I know that this is a two-year-old video clip right now, but I am hoping that you are still reviewing comments. If yes! Please shoot me a reply. I have a 2019 Insignia LED/LCD TV. That has perfect horizontal lines, across the entire tv screen. (Top to bottom, left to right). Help me Obi Wan FrugalNobi! You're my only hope!!

Thanks for watching and your encouragement! Did you try everything in these two tape videos? That should help you narrow down if it’s the lcd assembly or the tcon is at fault

@@FrugalRepair I am trying to determine where to start, because it's the whole screen (literally 100%, perfectly even lines. The only anomaly is at the very bottom of the screen, there is what looks like a dotted white-blue line riiiiight where the edge of the screen meets the plastic bezel). Regarding the tape trick, and trying to tape off pins 1 by 1... How do I know which TCON ribbon to start with? I left the TV powered on, while I removed and reattached the TCON ribbon cables... And the lines were still present regardless of which I unplugged. So.... Would I need to just block them 1 by 1? That would take hours, lol. They are practically microscopic pins haha 😂 I'd love you shoot you an email with some photos or a video. To get your input! Thanks so much for the fast reply!! You are awesome. 😎

The problem is actually on the LCD in most cases, not on the tcon.

Thanks for watching!

Good narration, with experimental, I like your video

Thank you for the video! My Sony Bravia has a double image issue. The T-Con board has only one FFC cable. Thinking of blocking the lines with a tape, would it work? What are the possible long-term issues? Also, how long would this tape method work, can I have a decent picture for 3 months?

I should have watch this video years ago. Thank you very much for this very informative video. excellent!!!
