You the man! I've suffered from hissing for weeks and was about to disassemble my LS IPS277 display to see what's wrong. but fixed by replacing power supply from old broken ASUS laptop (19V 2.3A). no more noise and display starts well. thank you!
My monitor also had a similar problem, monitor image flashes once on startup, then stays black and has a very soft hissing sound. Model: LG 23EA53. My monitor also only has a power adapter like yours. Replace with a new power adapter does the trick. You save me 100 bucks without a need to replace my LG monitor! Thank you! God bless u!
Thank you! I didn't needed to disassembley montor with a risk to damage it. But I also didn't replased power supply. I've replased a capacitor in it: 680x25.
I fixed it in a different way. I didn't had a second 19 V DC power supply at hand. I cut the cable of the original power supply and put in a 35 V 47 µF capacitor in parallel. That stabilizes the voltage from the switching power supply (ripple voltage). The screen turned on immediatly without any noise. I measured the voltage across the capacitor and it was only 12 V DC. That means the original power supply is not capable of providing enough current to sustain the 19 V . Still it works, and if i get hold on another 19 V power supply then i will use it instead. And the capacitor values are not so critical. The voltage rating has to be above 19 V and the capacitance shouldn't be much lower than 47 µF or above 1000 µF. If the capacitance is to high, it might be a problem when plugging the power supply in. Oh and always check polaritiy! Good luck!
Thanks, i soldered it (35V and 47uF as you said) in the monitor near of the power connector (assuring the + and -) and the space to mount it again. It continues hissing but a lot lower, about 90% less noise and for me its ok! Thank you so much!
I've got the same problem and I just replaced the bloated 680uf 25v cap on power supply but it's quite a pain in the a** to pry open the power supply itself.
perhaaps he mesure the original psu, and the V. are "normal" no suspiccius at firth instance, then dissasembly por check board and no sing o leaking CAP o burn board. he come back to the PSU.
Hello...I have basically the same monitor (IPS LG277l) using the same 19 volt external power supply (tested the output with a multi meter and get 19 volts reading) As of last night, I began to have an on/off loop issue. Unlike the monitor in your video...there is no noise. If I turn on the monitor apart my tower there is no on/off loop. Only a request to connect to the video card. I don't have another power supply to test as you did. Any thoughts?..thanks Alan
My LG Flatron IPS236 flashes like crazy when I boot up and when I reboot. It does so for a long period of time before it finally ceases. Could this be my issue?
I had a same problem with my IPS277L and fixed it in a same way - by replacing faulty power supply. It is hard to find exact replacement so just get yourself a universal one that has adjustable voltage output and a set of different connector pins.
Yeah okay, maybe it's the pin's measurement, it looks exactly like mine. it's just because as far as I've found there's no universal power supply available that supplies exactly that tip here, but thanks anyway :)
I have a spontaneous on/off problem with the same monitor but a 27inch.. one guy I brought it to said it could be the touch bar menu that is defective? any ideas.. ? could you fix it??
Hi guys please help, I have the same problem, I dont know if I buy a new powersupply or something else? Shall I buy the same powersupply as the old one or shall I buy another type of powersupply?
Thanks man, I love you! You saved my money and my pain.

Congrats on your fix, thanks for watching

Thanks a lot , my monitor was LG ips series and it have the same problem. You save me some time and money
I didn't believe at first and I just tried it...fixed! thank you again soooo much I almost bought a new monitor
Congrats on your fix, thanks for watching

@@laos1001 You're welcome! Nature appreciates everything that reduces electronic waste.
what why did u remove the panel lol
I had the same problem and fixed it like you showed, thanks!
You are welcome, thanks for watching
Thanks for the help luckily I have three of these LG monitors so testing the power supply wasn't hard at all.
I've got the same problem and I just replaced the bloated 680uf 25v cap on power supply but it's quite a pain in the a** to pry open the power supply itself.
Thank you! This worked for my LG monitor as well!
Thanks man. My monitor is working now. 😊
please tell me.. why dont you just replace the powersupply WITHOUT opening the monitor...

Need more people so spread this video more
Hello, I’ve got a similar problem. However my monitor does not show any output after I plug it into a pc. Should I try to replace power supply, too?

Hi, do you have the name for the connector pin that fits your screen? :)
It is labeled 6.5 x 1.4.
I think the measurements that fits mine is 6.5x 4.4 mm with a pin inside. You don't have the model name like a M7 19V or something like that?
imgur.com/a/dUm9V this is how it looks. Sorry I don't have any other name.
Yeah okay, maybe it's the pin's measurement, it looks exactly like mine. it's just because as far as I've found there's no universal power supply available that supplies exactly that tip here, but thanks anyway :)
Where could i get the LVDS cable for this? I can't find it anywhere
So the fix to this is buy a new adapter right? 19V 1.6A...
Hi Sir LG ki LED hai usaka display pe lainig arahi hai Sir isaka solocen bata dijiy please riflay karo sirji
my LG 22mp65 has a vertical line in the middle of disply..how can i fix it??
You try to give the video more brightness it will be great if you do
I have a spontaneous on/off problem with the same monitor but a 27inch.. one guy I brought it to said it could be the touch bar menu that is defective? any ideas.. ? could you fix it??
Same issue here
Hello can i have the reference for your Power supply plz ?
lgips led moniter 22mp56 no power no power led what is problem please help
thanks
Thanks 🙏🏾
YES! - with power supply from an old acer notebook ;)
I literally did the exact same thing by reusing my old Acer notebook 19v power supply to my LG IPS224 monitor. It worked!
Спасибо! Увидел как он рассоединяется. А то у меня появилась полоса вертикальная. Как раз в районе где шлейфы матрицы.
I bought a tablet and the screen is backwards how can i fix that?
The image is too offensive
Hi guys please help, I have the same problem, I dont know if I buy a new powersupply or something else? Shall I buy the same powersupply as the old one or shall I buy another type of powersupply?
Best option is to replace with an old laptop adapter. Almost all of them are 19 V and they manage too much power than a cheap Alibaba adapter.
piece of shit monitor. Never again LG, never again.
