FIX Your TV with a TOOTHBRUSH | Fixing Vertical Lines 

how to fix green bleeding on the edges of lcd/led tv?

Watchin from Jamaica can i get one of yr book

Good Morning FrugalRepair, Please how can i repair hisense curve 60inch screen that suddenly developed vertical lines, which start from middle and moves to the left side. i want to learn .

Cau I get thhe link.I mde one ad 5hi is amazing.thanl you

me i want your help my tv has all color vertical lines but sometimes it shows just ok without any line but some it just change

If I can figure out a way to fix that tab bond, I’ll definitely show it. I’ve had some minor success by cutting into the cable at an angle and then dragging a soldering iron (with solder) across it.

​@@FrugalRepair please Show it🙂

Wow, that's so encouraging to hear! Thanks for letting me know. And congrats on your repair!

That's great to hear! Congrats.

Thank you for watching and your encouraging words!

did you ever figure it out? Im having the same issue

Thanks for subscribing! Great to hear it helped.

In general you might get what you pay for. But even the big brand names have had strings of problems. Samsung and Sony had years of their TVs having significant issues. Vizio sometimes has a bad reputation but a lot of their TVs were made by LG.

Interesting...I have 10 years old LG and is still working flawless was low price range. Another Philips high range price also 8 years old have vertical lines.

Thank you for your kind comment!

Great idea. The main issue I see is dealing with the corrosion effects around that area and heat unfortunately, wouldn’t help clean it up.

Thanks! Congrats on the repair. Did you watch my video on vertical lines? It’s likely from a bad panel or tcon board. Hopefully it’s the tcon.

I'm not sure exactly what the damage could have been. I'd try to re-seat the cables that go to the driver boards and hopefully that is it. But it's also possible the lcd is damaged beyond repair.

Do you have a video on reseatting the Driver Board cables?

Thanks for your encouragement!

Heat might be helpful with the adhesive but it’s the corrosion underneath that is the issue.

You mean you have a good picture and in 15 seconds or so, the problems show up? That still sounds like a heat related issue and hopefully you can fix it with some non-conductive material under the metal bracket to put some gentle pressure on that tab bond. You can try turning down the LED brightness to something like 10% and see if the tv lasts longer (less heat in the tv). Or you can put a fan on the tv with the cover off and see if it lasts longer to isolate the problem as a heat issue.

Hope you can get it fixed. I hopefully have enough videos on the topic (plus the free e-book) to get you started. You might want to start with the video on what to do if your tv experiences a power surge.

If you have done the isolation technique I showed in the tape video then I would suspect a bad panel or tcon board. There is a possibility also, that you have a short to ground on your driver board that's causing the weirdness.

Watch my videos on fixing with tape for horizontal lines. It’s easier to correct than vertical lines.

That likely means the LCD is cracked and the LCD is not repairable.

if alcohol doesnt work, try wd40 and a paint brush instead. it has softer bristles and will will easily go in tight spaces. DO NOT GET WD40 ON THE ACTUAL SCREEN, IT WILL CHEW INTO THE ADHESIVES AND RUIN THE PANEL. a drop or 2 on the driverboard on the rusty spot will be just fine.

If you mean the yellow wires that have the tab bond on the driver board then no, you realistically can’t fix that, unfortunately.

If you like the picture, then I wouldn’t change anything. The issue is not on the tcon but on the lcd assembly (which you cant get a replacement)

@@FrugalRepair oh ok. Good to know. The picture as I see it now is basically flawless so no more changes then. Thanks for the quick response. Subbed too.

Thanks for that!

Thanks for watching!

No, unfortunately you won’t be able to repair that.

It is also recommended when using this method to overlay some PRINTER paper between the polymer flex ribbon cable and the iron. This reduces the RISK of damaging the cable. Uf one has or can obtain some thin TEFLON sheet - that would be even better - It has worked well for me - and the BAR attachment I use is made from BRASS ANY ENGINEERING WORKSHOP CAN EASILY MAKE ONE

have you ever tried it? It's really easy to melt the ribbon plastic if your heat isn't perfect. (pre-heath the board, if you're going to attempt this.)

I don’t really know but sounds like a bad connection somewhere. I hope it’s not the tab bond but you can do the trick of putting pressure on it with something non-conductive. It may be working well then stop because of heat. You can try disconnecting one of the cables from the tcon board (did you watch my fixing with tape videos?) and try to isolate which driver board might have the faulty tab connection

Agreed, it could be.

Hope the repair goes well!

How did it go?

I think it's a new screen on this one🙁 haven't tried a tcon board or like on some videos changing some dud chips along the LCD strip, but I had luck on a Philips 50inch. It was a different issue no picture at all just wide white strip down the screen, I took out both ribbons and cleaned then put back and hey presto, so far it's come back once and I didn't fancy opening again so I just unplugged for a while and woo hoo it's working so I've stuck it on my bedroom wall, now don't know what to do with the 65inch Samsung. Anyone have a screen for sale haha might have to buy a working one to swap parts and see if it's the LCD, have a great day thanks for asking I nearly forgot about that TV set

​@@FrugalRepair ❤😂🎉😢😮😅😊❤🎉 Well I did see somebody that he smashed into the TV in the TV was broke

I don’t think there’s much significance to it because sometimes the tabs are at the top.

They ended up giving me the tv and I haven't worked on it yet. My guess is the tape trick will work since it seems like a row signaling issue. Have you seen the videos about the tape trick?

i have, i will try that soon@@FrugalRepair

My guess is that the tcon cables are not seated correctly. Hopefully an easy fix and not significant damage done to the panel when it was removed to get to the backlights.

LOL, that scene I think I grabbed from stock footage. You have a great eye for detail!

⁠​⁠​⁠@@FrugalRepairI did wonder if it was actual footage of you or family/friend lending their hand😂Orientation matters! You have a wonderful talent and I truly believe you’ll be blessed for sharing that knowledge with the world!

It is not impossible but I agree, it’s practically unrepairable. There are some tricks out there to help connect the ribbon back to the driver board but if it gets cut or mostly removed from the driver board, I wouldn’t waste time trying to fix it.

Replace electrolitic condenser On the power supply,by 16 volt Original 10 volt,whit the Same MICROFARAD,IMPORTANT BRAND NEW TV!!!😝 I TS ALWAYS THE SAME PROBLEM. ON LG....SAMSUNG

I don't know what vinegar would do to the adhesive or the ribbon. I don't think you would want to put something acidic on a pcb anyway. Good thought on heat, I've not had success applying heat to these tv tab bonds so it's possible it could work. I would try to use something more like a soldering iron than a heat gun.

VINEGAR is Acetic Acid - and is corrosive. There is a paste available - most often used by Jewelers and watchmakers to remove corrosion from watches - that have been water damaged. One can imagine the intricate mechanical parts in an expensive watch - and removing corrosion requires special techniques. The paste is not exactly low cost - BUT one does not need to use much and not very often - so a small container won't break the BANK. I don't have it in front of me right now so I cannot recall what it is called. I would recommend watching some Watch repair videos - and soon enough you will discover what the paste is called. Once the corrosion is removed with the paste - the area can be washed /cleansed with a little amount of IPA

@@FrugalRepair The vertical line issue presented here is very similar to an issue that occurs on game boy screens. The fix there is to apply heat onto the ribbon using a soldering iron.

If you think it’s a vertical line issue then you probably don’t have much to loose.
