Solved the birghness controls appears and stays on

Do you mean the 'on screen display' for the brightness appears on the screen or the screen is too bright? I guess in either case the likely problem is with the monitor. If possible try another monitor and see if the problem goes away. If it is the monitor I'm sure it's repairable but the cost may make a new monitor more practical.

"on screen display' for the brightness appears and keeps being shown despite pressing other buttons

Try another monitor to make sure but it sure sounds like a monitor problem. Perhaps the brightness button needs to be replaced or cleaned. I also found this: http://www.p4c.philips.com/cgi-bin/... Try alternating between locking and unlocking OSD and see if that clears it up.

Could be that the "brightness-control" button is stuck in the "on" position. May want to try to press it repeatedly to see if that frees it up. Also may have to replace the monitor if that doesn't solve the issue (or deal with it being on all the time)... "Channeling the spirit of jboy..."

I wonder if there is any possibility that such buttons on monitors are normally closed (electrical contact unless pressed) rather than normally open (electrical contact only when pressed). If so, an open contact could cause the problem. Maybe caused by corrosion or dust. More than one keyboard I used (years ago, though) had normally-closed key switches. Removing a single keycap made all the keys electrically connected to it unuseable. -- Jeff, in Minneapolis

thank you! But i still didnot identify - is it a SOFT problem (i mean the monitors) or a HARD problem (buttons). I will come later with info

Hi there, I m sorry it took some time, i gave the monitor to a technician. He checked the buttons - and found out that there was a different reason. He said a capacitor in a "central box" was malfunctioning and after he replaced another one - the monitor began to work well. Thank you all for your support and ideas!
