I have had this monitor for several years, and one day the monitor buttons did not work at all and the input stuck on VGA (I always use it on HDMI). After several minutes clicking on the buttons and turning the monitor on/off (by disconnecting the power supply) the monitor turn to a solid color and start shifting between the basic colors and then it says passed (or something like that). I disconnected/connect the power supply and the monitor stuck on a mode were its flashes black and white (the whole monitor), if I click the buttons, they respond and a yellow square appears on the  center of the screen that says the button name, after pressing the 6 buttons (one by one) the legend change and says passed. Is there any secret button combination to exit this mode? I have try several button combinations and all that I have achieve is that the yellow squarer appears on the top left side (while pressing plus and menu buttons).
