My 42" LG LCD TV started playing up so I investigated. Here's what I found. I hope if you're having problems this helps you !

This is very helpful Simon. Very clear visibility into the modular design of the screen. It seems applicable to many different brand/models. My LCD screen has the left half with random opaque white problem. I tried to open the cover to check inside as you do but could not. There seems to be glue holding the top cover. But just by pushing on the top cover from the front the problem is gone (until it comes back :D). So I believe it's also due to the ribbons as in your video. All I can assume now is bad contact of the ribbons which are basically signal cables. Locking the ribbons by glue/tape or replacing it with a new one may fix the problem properly. Now I need to figure out how to open the top cover first xD

My lg 42" is doing the exact same thing as this one. I figure it is this one mine as well.. Tv is very old in terms of LCDs so it didn't surprise me it busted. And load and behold it is the same problem you had. Little bit of electrical tape. Going to leave the case off the tv until the tape settles to see if it is fixed. Good video. I was about to take it outside and take my shotgun to it :)

My 42 in lg tv looks just like yours did before you started touching the ribbons. Thank you for posting this. Now I know which direction to go. And if mine does the same I'm gonna try like you said to make it happy. Thanks again for posting this video. Its the only one that has the same symptoms I have.

The panel for any screen is rather expensive and not worth replacing. You can fix the tabs though (and I don't mean a ghetto repair where you just shove something on it to keep pressure on it). Basically the glue that holds the tab onto the LCD panel separated. You can reheat the glue and apply pressure to the tab while the glue cools down to fix it. Just make sure you don't slide the tab in any direction as the connections are very small and usually take a microscope or video scope to realign.

I managed to improve it a lot! It took some time to find the "hot spots" where the ribbon needed to be stuck down with masking tape. Once the masking tape had been stuck down solidly and in the right places the TV hardly ever played up. If it did I had cut out small grooves so I could prod the ribbon with the rubber end of a pencil. Not quite as good as new but certainly far better.

Hi Simon I had the same problem with my LG 42" t.v. After watching your video I decided to check inside and it was exactly the same. There are foam pads that run along the metal casing I just swapped them from the front of the casing to underneath the the top part so it pushed the ribbon back into place? Not sure I've explained this clearly enough but it now works, all thanks to your video!!! Thanks, you've saved me a fortune, your a legend!! Simon Phoenix
@SimonPitt11 жыл бұрын
Hi Stuart, I'm glad the video helped :) Is your LCD mounted (on the wall) or on it's stand? I think the stand is awful and heavily contributed to the fault as when the TV moves it bends the chassis inside. As for the heat gun I'm not sure. What would the heat gun do? I'm not sure how it'd help. You'd have to be very careful too as if you heat the ribbons too much they could crumple/contract/shrink and completely damage the connections. Without a good reason I'd steer clear to be honest.

Hi simon, cant thank you enough......my lg 42" tv had the same half screen fault, going completely after month's of playing up and had sat in the spare room collecting dust till I saw your vid. so armed with a bit of knowledge and some inspiration I got to work. I only had one dodgy ribbon cable and it seemed to be the actual board causing it not to sit correctly, the board seemed slightly warped and lifting up so I used so some strips of gaffer tape to hold the board down and job done :-)
@SimonPitt11 жыл бұрын
Hi Chris, Yes I did manage to fix it. I used masking tape to stick the ribbon down to the frame so it could not move and disrupt the signal. It took a few goes to get the masking type in the right position and I did a couple of layers to make it stick firm. Find which ribbons are problematic and then try sticking them down. Please let me know how you get on. Thanks, Simon.
@SimonPitt11 жыл бұрын
Why do you need to use a torch? Are the left and right backlights illuminated at the back of the TV when it is turned on? If they are both on then you don't need new inverter boards. Have you tried touching the ribbons around the screen to see if that fixes the issue like I do in my video?
@IzludeTingel7 жыл бұрын
Thanks for this demo, I can now assume that one of my driver boards is absolutely dead. My TV (LG 60LB6100-UG) has 4 of these boards, each responsible for 1/4 of the screen. The far right shows a rainbow distorted image (garbled) and unplugging it from the ribbon chain results in that portion of the screen going pure white. That means the backlight and panel (pixels) are fine, but the driver board is toast and can't process a correct image on that part of the screen anymore :(

This can be easily repaired with blu-tack and a few cocktail sticks. A friend of mine lost half his picture on a 42LG3000. So I took it apart, put blu-tac under the ribbon cable on the far left with four cocktail sticks stuck in it. Hey presto, when I put the thing back together it works.
@hibbsy200511 жыл бұрын
At the time I hadn't seen the reply so I stuck the actual board next to the ribbon down because wasn't sure if I could stick anything to the ribbon and also took advice from another comment and took the foam board from the front of the metal casing and placed it on top where the ribbon is. So far so good but had the same ribbon prob as you. Will let you know if it stops working again but your video was the only helpful one I could find. Thanks you have really helped :-D.

Hi Joe, Thanks for the positive feedback. We can still use the TV it just takes some time to wobble it on it's stand and get the complete picture. Not a perfect scenario but we'll see how long it lasts before the wife's had enough :) IMHO I think it's the stand that caused the fault. The stand is weak and inadequate. When the TV is moved the chassis inside the TV slightly bends. If the TV had been wall mounted I don't think this would have happened. Regards, Simon.

It could be the inverter boards that power the backlights, however I find it strange that both would go at the same time. If you look at the power board do any of the capacitors look "bloated", "expanded" or "dome" shaped? If any of the capacitors look bloated then it could indicate they are no longer working and it could be these that are not powering the inverter boards. Also check the connections to the inverter boards. Be careful here as the power board and inverter boards are dangerous.

If u need to secure the ribbon cable then I recommend those sticky floor protectors you get from pound world. They are normally used for sticking to the bottom of chairs etc to stop scratching laminated flooring. You can get felt ones and ones made out of polystyrene type stuff. When the LCD panel surround is replaced these give enough pressure to keep the ribbon cable in place. I fixed a LG using this method and it lasted 3 years - just developed another fault whereby about three inches on the left hand edge is black when u put the set on with a thin vertical line in it. Sometimes it flashes and u can see the picture, sometimes it's mixed with some of the picture from the right so I'm maybe thinking the t-con board??? Any ideas?? I'll try and upload a video shortly.

Hi. Thanks for this video. I have a different TV but it was quite useful to understand how to identifty the source of the problem. The left side of my TV gets dark/red and I just found that playing (plug/unplug/press) with one of the 4 ribbon bands from the TCON to the panel it gets ok. However when I turn the TV off and then on again, it just gets bad again. Switching the position of the ribbon bands it happens exactly the same and with the same ribbon position which for means the problem is not with the ribbons. Do you think that the problem is the TCON? Thanks
@SimonPitt6 жыл бұрын
Franclim Bento it could be the ribbon ports on the panel or TCON board if swapping the ribbons does not clear the issue. Not an easy (or cheap) one to investigate as you obviously can't replace the panel so you could try another TCON board but it'll cost and it may not fix the issue if it is the panel. Good luck and thanks for commenting.

WizardsMagic007 Did you try using a rubber (eraser) to clean the connectors? By my experience, most small lines occurring down the screen are the result of dust getting on the metal ribbon connectors that attach the T-con board to the screen. A firm rub over those metal contacts with a rubber tends to clear them up.
@WizardsMagic0079 жыл бұрын
FX Lord I think it's a tab bond problem. If I press down in a particular way on the left center tab bond, the lines will go away. However I have to fiddle with it just for the lines to go away (it needs to be in an exact position). I'll clean the connector off anyways, and see what happens.

WizardsMagic007 Just had the same problem with a 46" Samsung - I would get it shimmed up and looking great, but then as soon as I replaced the metal frame and snugged up the screws a single row of pixels would crap out. Even leaving the center screw out of the frame, which solved the problem so far as the bad row was concerned, was for naught, because as soon as I reinstalled the plastic surround properly it would crap out again. I took that thing apart 3-4 times before I somehow (and I really don't know how) managed to crack the LCD. Sigh

make sure there is enough pressure from the blue tack that when you replace the metal case around the ribbons there is pressure on the case pushing the blue-tack against the ribbon which in turn pushes the ribbon to the board. use a bit of thermal tape under the blue tack to to make sure this will not move. if you can stop it from moving b4 you put telly back together only then put it back together reason being the screen will heat up move and flex and it shouldnt be able to move just flex if you know what i mean. IF its still moving about then your always going to have issues and most probably make it 10x worse. start the repair again and get right! make sure it don't move the ribbon when the metal case is replaced.

SO. i just fixed my LG 42lc4d tv, few capacitors blew out, so i replaced them with slightly bigger ones, before this the tv popped before turning on and took forever and a day to turn on. Now, the tv just instantly turns on, the back light comes on, then when you let it sit on a no input screen, it flashes and flickers and slowly starts to even itself out, takes about 20 minutes now. any idea's on what that could be?

I've looked all over and only find the replacing capacitors will fix it, but i already did that
