Menu screen keeps appearing

Either the battery is dead or you need to change the sound setting that keeps unit off when it does not detect sound to protect the battery.
Another person said.
".We have this one. It must be in the sound activation mode, which helps to save the monitor's battery life. If it's in that mode, you'll see what looks like a crying baby icon along the top of the screen and the screen only turns on when sound is detected in the room.

To turn the mode off and keep the monitor on all the time, just press the Menu button on the right (in the middle of the arrows), press the right arrow until you reach the crying baby icon on the far right (so the icon gets big), press the Menu button, and a check mark and an X will appear - the X will be pre-selected and appear red. Just press the Menu button again to select the X and turn that mode off. Once back to the Menu screen, arrow up to the Return button on top right and press the Menu button to exit."
First years talk and soothe video monitor help

From time to time, I've the same white screen problem with my IIYAMA E1902WSV.

I can resolve that issue with a reset to factory settings.
1- Turn ON power (blue led)
2- Push on the MENU button and keep the button pushed while
pulling out the power cord.
3- Plug the power cord back while keeping the MENU button
pushed.

You should see the picture again.

OSD (On Screen Display) lockout. To resolve the issue you can hold the power button of the monitor until you get another message something similar to "OSD unlocked"

try holding menu button also if it doesnt workout

Make sure that your computer isn't going into Standby or Hibernate mode. You can test this by briefly pressing the power button and wait to see if the screen comes back on.

my hcl 17inches monitor is displaying contrast,brightness etc automatically
in the middle of the screen.even if i press the menu buttons it
disappears for a sec and comes again and again.what should i do to
solve this?

on your monitor...
you would find the menu button..
click on it.. you would find options to move your screen ... use the appropriate button to do so.. and you can centre the screen..
hope this helps..
if you need any clarifications please feel free to reply

It seems you might have an issue with the dmd board. Go to the menu, and if the dots still show on the menu, the issue definitely is with the dmd board but if they don't come up on the menu, the issue will be with the video board.

5-22-09 Same problem last month. I had the problem a year ago for a month, then it stopped, reappearing this last month. Last week, I finally called support...I was accidentally transferred to a Dell "internal" technical support department...happily a very diligent technician spent a bit of time with me for free...for same problem, even though he confirmed I was over a year past all warranties. He confirmed this was a monitor problem (not virus, malware, etc.). He also confirmed their standard "guidance"/solution for this monitor issue (if under warrantee) is to replace the monitor (i.e. not attempt to fix it). New monitor needed. But problem again gone for last 10 days. So, when fully irritated, buy new monitor.
