Monitor backlight turning off?

post #1 of 9
Thread Starter 
Hey guys, I was driving my friend home today and I saw a monitor on the side of the road so I grabbed it. It has a weird issue where when it is turned on the backlight comes on for maybe a second then turns off leaving the screen black with the LCD still on. Here is a little video of what is going on.

Check it out

Any ideas? Should I pull it apart and see if anything inside is messed up?

That is infact a picture tongue.gif

But one of my monitors had this problem, its most likely bulging caps, they are easily changed out for some new ones, just make sure you get the right ones (it says on the side of the original caps what you need)
Good find btw

It's worth a shot opening it up and checking the caps.

What brand is it? I know I have saved a couple of my Samsung monitors by replacing the caps that went bad to the cathodes. Assuming it is using that and not LED lit.

Just a few quick searches and found a few others same model with bad caps needing replaced. So yup, sounds like it very well could be a simple 10 minute and under $5.00 fix.

Nice grab. thumb.gif

Sweet, now to get it apart... These things are apparently a pain to get apart...

Edit: I can't get it open, my fingers are killing me ATM.

Okay, I got it apart, none of the caps look bad, I am stumped. Is there anything else I can try?

Fixed it, I changed the backlight connections around and it works now. Hurray for people leaving their old stuff on the curb!
