I'm on the verge of taking it back but i know there is probably something that can fix the issue before I do so.

 

Everytime I log on the monitor stays bright for about 10 seconds and then goes to an almost black dim setting.  At that point i then need to reach my finger underneath and go through all the steps to get brightness back up to around 50.  At that point it's set and then unfortunately next time I arrrive to start computer up either from fully off to just hibernating the same problem occurs.  It resets to ZERO.  Can someone help me please ?

 

Thx

    When it comes on and it's bright, is it brighter in some places than others? you could have 1 backlight out and the inverter board will shut them all off if it senses unequal power going to them.If they are all bright, you could have a bad inverter board.

    You could have a bad capacitor on the board

    No, it comes on perfect, the way it was set the night before.  Then 5-10 seconds later it just goes dim to where you can barely see what's on the screen.  Then i have to manually adjust back to 50 brightness and it stays until the next time the computer is fired back up.

    Try replacing the inverter board.
