LED backlight stopped working - bad capacitors?
Hi all - new member here :)
My Asus VK248H monitor finally died on me.
The LED backlight had been randomly turning off for some time. Turning off the monitor and waiting a minute before turning it on again, would make it work for a bit.
Now the backlight wont come back on, but I can still see the picture although it is really dark.
Since I was going to throw the thing out anyway I decided to take it apart and have a look.
Not sure if it shows, but there are no visible bulge or leaks on any of the capacitors.
The capacitor brands appear to be "Elite", "Lelon" and "Chemi-con" (I think).
Should I go ahead and change them and if so - what are the good brands?
Picture of "the other board":

The other board looks like this.
I'm going to pick up some new capacitors (Panasonic, Nippon Chemi-Con, Nichicon or RubyCon) from eBay, and maybe even a cheap ESR meter, and have a go at it .
Edit: can't post pics in comments so I edited the original question.
