It may be a malfunctioning circuit board controlling the buttons on the front. If it's under warranty ship it back to Philips; if not markgladding on this site sent me the following advice. Standard disclaimers apply and any questions or comments should go to him. -------------------------2nd hand advice begins-----------------------------
If you open your monitor you will find a small circuit board with a row
of microswitches mounted on it. This is the circuit that's causing the
To open your monitor you will need to remove the stand (one plastic
cover that unclips by hand and 4 screws that can be removed with a
philips screwdriver). This will then reveal two additional countersunk
screws that need to be removed.
You can now remove the front cover. There are 4 clips at the base of
the cover that can be removed by hand. You then need to pry the cover
off, starting at the corner next to the power button. This is really
quite stiff and you need to use a reasonable amount of force. Don't
worry about the loud cracking sound as each clip along the side
Once the cover is removed you will see the circuit board with the microswitches staring you in the face.
This board needs to be replaced but if you want to fix the problem immediately here is what I did.
Disclaimer - Proceed at your own risk from here on in.
Plug your monitor back into the power and reconnect to your PC. Make sure it's on and still showing the same problem.
The circuit board unclips and there is a 7 pin connector that also can
be unclipped. Remove the board and undo the connector. You don't need
to switch off the power.
After the board has been removed for a few seconds, the on screen display that was permanently visible should disappear.
Now I temporarily disabled the malfunctioning button by bending the
associated pin on the connector 90 degrees and then reattaching the
How do you know which pin is associated with which button. Trial and
error. Simply bend down a pin, and reattach the connector. If the
problem persists, unplug and try the next pin.
When you've found the correct pin, straighten the others and reattach the connector.
Clip the circuit board back in, making sure the connecting cable is clear and doesn't get pinched.
Reassemble your monitor and you're good to go.
The next step is to order a new circuit board from Philips. These
should be really cheap (I hope) and you now know how to fit it yourself.

Not sure if this is exactly the same as yours your model hard to find I had 2 similar monitors at previous employer and they both operated the same way
Taking a Look
1. Power Switch
Pressing this button turns the display system power on or off.
2. Menu/Select ? Pressing this button pops up the OSD menus on the screen, and used to
select ("Up" direction) the OSD control options on the screen.
? This button is used to select ("Down" direction) the OSD control options on
4. + This button is used to increase the value of the selected OSD control option.
5. 0 This button is used to decrease the value of the selected OSD control option.
Quick Adjustment Function
When the OSD Menu is not active, the following functions are available for the quick
Pressing ? button once pops up the OSD Function Main Menu .
Pressing ? button once pops up the small Brightness icon. Use +or 0button to adjust
the Brightness level.
Pressing + button once pops up the small Volume icon. Use +or 0 button to adjust the Volume level.
Usually for the volume bar to just pop up something would have pressed the volume button. It is possible that the volume button has gotten a malfuntion on it and this makes it to pop-up all the time. Try getting underneath the volume button cleaned. But preferably this should be done by an expert. Hope this solution has been helpful?
For presice adjustments of VGA input run the Auto Ajustment Software on the CD
Additional image quality improvement use the clock and clock pahase controls of the monitor to fine tune the image Clock increase or decrease the value to minimize any vertical bars or stripes visible on the screen backgroung Clock phase increase or decrease the value to minimize video distrotion or video jitter
allow the monitor to heat up before adjustments
use the adjustment pattern application provided ont he CD
select OSD menu to select image control and change clock or clock phase
Incase of any error restore factory settings select the OSD menu and select factory reset and select yes
When this occurs with mine, I power down the PC through windows and the monitor using the lower right power button, let bot sit for 10 - 20 seconds, then power on the PC and switch on the monitor a second or two later and the icon disappears.
Before I did this I found it would eventually disappear.
Acer support claim the H243H is a touchscreen unit, that's what the icon is all about, buy you must have Vista to use it, not XP.
Sounds like one of the front panel buttons is stuck in - possibly the volume down button.
If no buttons work, this could be the reason why.
Just a guess.
If they all feel OK, it may still be worth pulling the back off, (Without electricuting yourself -DISCONNECT POWER!) remove the PCB board that has the buttons on it, and see if it turns on without the menu. If so, check all buttons, rare but I have seen one that looked fine but with a multimeter it showed it wasnt working. If the screen still displays the menu, Id say there is a bigger problem...
what you may need to do is find an accepted screen resolution, as your screen is 19" widescreen and your notebook will be set for a normal monitor display, so either try the auto button on the screen or look at the properties of your graphics card om the notebook to find supported screen resolutions for extended displays.
Computer seems fine,
Cable changed. but still the same.
This is to expected, the monitor mounted controls are directed to monitor not part of the data input.
Thus suggests a board failure in the Monitor.
Just to prove the point if you have the monitor driver installed delete it and run as generic monitor.
If things change reinstall the dedicated driver
Though I suspect this is a monitor failure not computer related.
