DUDE THAT CAP AT 4:30 (looks like a little battery with 2 wires connecting it to the board) was clearly swollen that's the problem I know this video is old but I hope my comment helps someone in the future! That's a very common problem they use very cheep caps in very expensive tv's on purpose. It's called planned obsolescence those caps are literally 15 cents! un solder the 2 wires from the other side of the board and replace with the same volt and milliamp cap it will work fine I fixed many hundreds of TVs and resold them and more times than not its one of those dam caps! Especially if the tv wont even turn on but the power light is blinking its one of the caps on the main power supply board. always look at the difference of the end compared to others its clearly popped on the end and swollen.
Check Signal Cable. Decoder to LCD screen Flat Cable connectors. Push in firmly. Possible contact problem due to greasy finger print or something. Not the power supply, but decoder board to LCD.
This is a bad way to do UA-cam videos! Probably you have much time to waste.. if you want to show defect show it and stop, do not show all the tear down process, i first thought that this was a video solution and wasted my time.. :(
thats because u r a genius probably, who can t read the description of the video, ahhh, u ll gonna lose and waste many many years with that shiny brain of yours
@MegaRami92 Thought IF your problem is exactly the same as mine, then I assumed that it would be TFT panel to be defective. But then again maybe not, it could be the circuitary component(s) as mine is intermittent if I dismantle and press them down, and turn back on again...still the results be the same. Oh well, if i do have the time and pull myself away from gaming, i will try to rectify asap.
@icepipe2 must be the silicone I/C chip and I cannot presumed it. Thanks for the tip. I will search around any 2nd hand store for any to bring this fella back to life.
actually it is t-con board or timing control board "not t-com". Its just one of the possible reason another is the ribbon wire connecting to the LCD itself.
Have you tried using the VGA input instead of the DVI? Your video showed vertical bands of color. I have seen this with poor connection at DVI connector so maybe wiggling connector will change? If so maybe cold solder joint where connector is attached to circuit board. Try poking on components with monitor disassembled to see if anything changes while tapping on parts. Even though the electrolytic capacitors looked good in power supply there could be a bad one letting ripple through
hey guys, i got the same monitor but i am not able to open it to try to repair it. in this video it is not shown how to open. it doesnt work to remove the frame with screwdrivers or plastic cards. Can anybody help me?
i think this monitor is sold out in 2017 but if you have problem like that, 1 step.. check 12 volt output from psu board using a multimater also test every diode, check 24volt output to inverter is every voltage ok? voltage parameter you can read on your psu board.. i bet its less power to inverter, replace 2pcs smd power mosfet inverter under psu board.. if all voltage to mainboard and inverter is good.. cleaning your lvds cable and flex cable using an eraser..
I have a LG Flatron E2290V that just randomly cuts out to a black screen. This is a replacement monitor after the original one I purchased started having crazy wavy lines all over it. LG has some major issues. They sent me the replacement monitor with the wrong power adapter. Another week goes by, I get the correct power adapter only to find out the new monitor doesn't work! The only good part about LG Customer Service rep has been great trying to get this resolved.
Similar problems on LG e2411 except just get shadow in random places does not work at all using DVI only VGA caps look ok but I don't have a meter , I reckon it's a voltage problem the HDMI negotiation doesn't work
Dude,its display has damaged.i was having lg led monitor E2040T.for which problem was perfectly the same as shown in the video,from start to end.There is no any problem in its motherboard,i cross checked changing it's capacitors,crystals.but the problem remains the same. So finally I purchased a new display,just to make sure for my judgement,and it worked absolutely fine.So I recommend to take a new monitor,as the display price is high.
@ObsessedGeorge I don't think so. It's something to do with circuitary component failure. The problem was intermittent and most likely on the Relay, Regulators or Capacitors. Anyway, I had taken down all the specifications on all the components for purchase and will replace them one by one. Once done, I will update its status, here.
@MegaRami92 LG W2242T-PF LCD Monitor Problem. Hello . Have you fix the display? I have a LG W2252TQ same problems. No bad Caps. Please you have a tip for me ? Thanks
i hv a monitor that does that,, and when i opened it i found out that there are several belts that comes from an lcd small board and one of the belts was faulty ....if i touched it was getting back to normal aftr somtym or if i moved my monitor it goes bad again so i guess lcd replacement is the solution
Mine is doing the exact same thing except mine is a 24" onn brand 1080p monitor but exactly the same i have checked every little thing i dont see any issues so i may take a chance and order a T-Con board did you eventually figure out this issue and fix it if so what did you do or buy to fix the issue?
Noped. Had actually bought or an upgrade to a new 32" Gaming monitor from AOC. Had fed-up to rectify what causes the problem. I will put up a video as soonest as possible about all my PC hardware that currently had.
I just opened up the same display, if you have the same you would know that only at the powersupply these type of caps are located. I quickly got the caps out and tested them with my lcr meter but they just seemed fine. After placing them back and searching for other causes I heard the coil on the display pcb (under the metal cover attached to the display lines). also the interval frequency of the coil hickup was the same as that of the misformd picture showing on the display. Still suspect the input voltages to be faulty and making that switching supply (coil) hickup. Still have to measure the voltage lines but was to lazy to get one of my scopes and just told my brother to buy new screens anyway. Since a lot of people have this problem I will make some time soon and do some measurements trying to figure out the fault.
My monitor of the same brand, gets this problem after a long time of use, works well for more than hour and then starts this problem. I took the back cover off and plugged in a side fan for testing and the problem ended. Is it a heating problem? Because with the fan on behind the lcd the problem no longer occurs. So now I'm going to try to put a heatsink on each component to find out where the problem is or I'll install a mini 12v cooler to see if it works out because I want to close the monitor since it's working open. If I discover news, I'll be right back.
I've had my LG 23en43 for about to years and it did the same thing only worse. I can even see what the computer is doing. Do I need a new monitor or is it fixable
That's a shame, I have the W2242T too, it's about 1 month older than yours. It could be a problem with the decoding circuitry inside the flat panel itself, so it might be a write off. I was hoping mine would only need a new backlight after ~5 years, I hope the circuits don't go bad like in yours. I use it heavily, but put my PC to sleep whenever I'm away, so it probably does 8 hrs per day, but it does that EVERY day.
same fault in phillips 174b lcd and i note thet if i touch one leg of crystal not other with a steel tweaser it worked fine. crystal in that case was 14.318 x and there is a genesis processor in that lcd i tried to change that from old sound cards but think they are all faulty. now the project is pending.
У меня такая же неисправность много вертикальных полос и много цветов радуги и воняет чем то, маленькая плата где разъемы приходят с компа, на ней пробит был транзистор большей вертикальный черный такой после его замены стал включаться монитор, до этого не включался, рядом ещё одна микросхема, они рядом стоят восьминожечные, и рядом стабилизатор на 3.3 вольта, слегка поджаренный край, микросхема ближе на плате к двум электролитам она зажаренная весь верх не понятно какая, на вашем видео как бы видно её но тоже прочитать не могу сливаются буквы цифры не четко видно. до платы не могу добраться что на самом мониторе, болты не хотят откручиваться, я короче плюнул, а пущу ка я его на радиодетали матрицу выкину в мусорку, куплю новый монитор так лучше будет. Плату нашел на али-экспресс там цена 3 тыс руб, на авито за 1 тысячу руб монитор продают.
@XxBaTtLeToThEdEaThxX Yours is software related (hardware not so possible): 1.Uninstall ur current graphic drivers 2.Reboot PC into Safe Mode by holding F8 3.Still in Safe Mode, open Driver Sweeper or CC Cleaner (if you have either one) to get rid of the 'residue' 4.Reboot PC into Normal mode and install the Graphic Drivers, and Reboot it again to see results. 5.Scan PC for any possible infected Malware, Adware or Viruses that may cause any unwanted Startup programs.

I didn't understand where is solution, I have same issue with my monitor, can you tell solution to solve it
maybe are the flat cables over the panel or the flat cable from the video card, or a faulty chip on the video card, all about the video signal.
I have a similar monitor, I also have a issue to LCD, but not as bad as that one.
Still have this monitor and while using it I think it decided to die today, it's on and there's no display-

você descobriu qual peça estava com defeito na época? estou com um monitor da mesma marca e modelo com esse problema.
How many hz does this monitor have
Just stay away from lg products they are garbage. Had a nexus 5x ang lg watch style both dead in less than a year and a half.
@geraldlkc Oh, it is intermittent? Question: Is the relay the ribbon in 3:35? Is that what you are reffering to as relay? The ribbon?
8:41 Oh well done Gerald XD (I'm not hating on you, it was funny when it got turned upside down.)
How much it costs for repair??
u find problem? i have same problem
the problem is in the built-in t-con card that has the lcd, check the voltages a diode or smd resistor may be bad
same monitor and same problem here :(

Same monitor same problem.Problem solved... i changed 3 capacitors the 2 470μf 25v and 1000μf 25v.Good luck to everyone
but they were in logic or supply?? and what is concerned voltage is it 3.3 5 or ?
