by momakaNormally, I never post repairs this quick after I do them, because… I am usually very slow.
But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though.
I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...

by Rick_1234Good evening, gentlemen.
I have a problem with my monitor. It turns off after a few seconds or flickers. Shining a flashlight on the screen doesn't show any image, so I guess it's not the "2 seconds to dark" I read in the forum.
To turn it back on, I have to press the power button twice. Then after a few seconds it turns off again or flickers. See video.

by momakaLooking through my repair pictures and notes, it's been a long time since I posted anything in the LCD monitors section. So here goes that.
I'm dedicating this thread to one of the very first LCD monitors I repaired (if not the first one), which was more than 10 years ago now. The monitor is a Wise Wing, model F199. It's a 19” CFL-backlit LCD. I got it for free off of Craigslist in 2009 from a guy, who said he bought it for cheap from Wallmart and the monitor worked only for a little less than 2 years before quitting.
When I saw the Craigslist post, I wasn't...-

Hi all
Does someone has the test points \ schematics for lg eax65543115 ( 22" version, lg led monitor)
Or any ideas how to troubleshoot it?
The screen turns on for like 10 seconds, then goes off ( kinda protection triggered, as it goes off like you've been pressing the power button)
, but the cpu gets hot quickly within those 10 seconds , AND STAYS HOT EVEN WHEN IT'S OFF
I'm suspecting it gets over voltage \ current and triggers some OV \ OC PROTECTION but hopefully it's not too late ( that the chip is broken)
NOTE that it's a trashpicked monitor...-
