My friend picked up a used AOC tft22w90ps monitor, it worked for about a day, now after a few minutes the screen goes dark, when it turns off the on screen display is also not working. I haven't looked at it yet, any ideas? He said he removed all the screws and couldn't get it open. If it's something easy like bad caps or a burned resistor somewhere I'm going to fix it, otherwise it's not worth it, the monitor was a $13 find at goodwill, it was manufactured around 2008.

Re: AOC tft22w90ps intermittently turns off.
Can you see an image if shining a flashlight on the screen?
Also you will need to get it open and take pictures of the boards and overall layout for us. -
Re: AOC tft22w90ps intermittently turns off.
I am going to my friends place to look at it in about an hour and then I can put up some pictures, and check to see if it's the backlight. Is there a trick to get this thing open, my friend might have just missed something, wondering if it has screws hidden under the bezel or stickers covering them. He said the case didn't give at all after he took them all out. I can probably figure it out but it could save me some time. .Comment

Usually just having to gently prise them apart after all screws removed does itComment

Re: AOC tft22w90ps intermittently turns off.
There's quite a few vids on Youtube on opening monitor cases. One trick is to use a credit card to open the plastic clips. Easier to see someone doing it than to explain.
Good luck

Good 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.

Normally, 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...

Hi Everyone
Lately I am experiencing the deja-vu incident on one of the led monitor like this.

The monitor will randomly blackout and display no signal and will recover again.
Sometimes need to power and off again to restore the display but... -
Looking 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...
