Question about Samsung Syncmaster 17" 720N Monitor
I've had this monitor since March or so, about 8 months. Recently, I've been having a most unusual problem. When I am using my computer, the monitor will adjust the brightness without my input. It brings up the box for adjusting it and it increases brightness at apparently random intervals. Sometimes, it jumps up to 100 as if I were holding the button myself, and sometimes it sits at one number for a while, then moves up, sits at the next number, and so on. This would be much less bothersome if the box didn't come up. I can't close it and it blocks the very center of my screen (in fact, I'm typing blind in segments of this box because my monitor is adjusting its brightness)
It only adjusts brightness and it only goes up--these are affected by the same button. Nothing is leaning against the buttons or touching them from any direction. Help!!
I have already posted on this in another similar thread. But I will briefly suggest that you take off the front surround by removing the stand and undoing the two screws at the bottom rear corners. you then have to prize off the surround. While doing this check how well the small white connector, to the button panel,is connected. If necessary unplug and replug it to make sure that it is well seated.
Refit the front panel and you may find that the problem is fixed.

Sounds like the backlight is failing already. If it still under warranty, take it back and have the manufacturer fix it.
