Re: LG 22EA53VQ-P "crash" after 5 min.
Sorry I couldnt upload photos from my Android Xiaomi Note 8T with chrome browser in time, now im at my computer, will do.
I couldnt upload the original images ( they are 10376KB-13585KB each )
Google drive so u can see original images:

Re: LG 22EA53VQ-P "crash" after 5 min.
Hello again!
Sorry for being late.
The pictures you asked, i hope they are enough high resolution: [url]https://imgur.com/a/Sulvpgt[/url]
Also, i couldnt measure the resistances with my multimeter set to 200Ω, i had to go switch to higher range so i could only take the same measurements again, with the same results, 200Ω would not read anything for me. (out of range?)
I suspect Capacitors: C125, C126 are burned out, checked them respect to ground and only one leg of C126...Last edited by Zariel; 09-20-2021, 12:08 AM.Leave a comment:

Dear Momaka!
I will post everything you asked when i get home, wednesday!
I have a Manual multi meter, i have a picture of it: [url]http://imgur.com/gallery/kDfMAjT[/url]
Yes i had no clue about how the resistance mode worked on my multimeter, but now I do.
Will test in 200ohm next time when I'm going to post.
Also i bought a Caterpillar S60 since then so i could use a thermal camera too, finding possible shorted components.
Again, thankyou very much for your efforts...Leave a comment:

Re: LG 22EA53VQ-P "crash" after 5 min.
Hi sorry for the very late reply, had life changing events.
Today i found the box with the monitor again. haha.
The inductor burned out, smoked so i had to get it out.
Now i only get a blank black screen so backlight on, no smoke, no heat.
Maybe theres a short somewhere, i dont really know.
I did the measurements (years later haha, sorry) you asked.

Re: LG 22EA53VQ-P "crash" after 5 min.
Okay, i done what you said step by step.
The following happens: There is no buzzing sound so yes the t-con board is disconnected and the screen is turned on fully black.
There is no flicker at all, perfectly fine black screen without any noise.Leave a comment:

Re: LG 22EA53VQ-P "crash" after 5 min.
Yes with pc and without pc too, its exactly the same and the timing is too.
But, when turned on after 2-3min it does a little flicker for 1-2 secs, and a pitch noise comes from the monitor then the picture is perfect again, and after 2-3 min again the monitor goes like in the video.
Seems like one component is failing while in duty but i dont know which one.
Edit:
Maybe the buzzing noise comes from this component only when the monitor goes bad:...Leave a comment:

Dear momaka!
Thankyou for your reply.
No, it takes another 5 mintues to flicker again when powered down/up.Leave a comment:

LG 22EA53VQ-P "crash" after 5 min.
The monitor is perfectly fine for 5 minutes and after that shows flickering, see the video.
I checked the powersupply, the voltage is ok.
All i hear is a pitch noise coming from one of the components in the pcb.
Anyone has ideas?

Re: New Members - please post your introductions here
Hello everyone.
Im a beginner at soldering & electronics, looking forward to learning much more in this forum!
My first repair was a Samsung LCD monitor it had a bad cap, it was a great feeling!
Second was a videocard and it had a broken smd resistor easy fix
My third repair was a videocard too, it had bad memory solders, i resoldered them and it works! haha.Leave a comment:
