Hey Bob,
I just did this and the following worked for me.
1. Orient the monitor so the base is facing towards you and the top is facing away from your. Make sure the monitor is LCD up.
2. Grip the gray plastics just above the buttons and flex it up and towards you. You should be able to see the button control panel.
It should flex enough for you to rest the bezel and screw holes on top of the underside bezel. When doing this you have to wedge your finger tips between the LCD panel and the gray plastics to separate it. The trick is not to apply too much pressure to the LCD panel itself so you don't damage it. Almost all your pressure should be applied to the gray plastics as you lift "upwards" away from the LCD.
3. Once you have done this, you need to slide the bezel away from you towards the top of the monitor in order to release the side tabs and the top tabs. I found the best way to do this is to push upwards or away from you along the bottom left and right corners of the monitor and move upwards along the side of the monitor.
4. Once you have release the side latches the whole bezel should just slide upwards or away from you.
Note: When replacing the bezel you need to start from the top and insert the top tabs first. Then align the side tabs and last align the bottom button portion of the bezel.

hi every one, i hope this helps and am proud to say/or not that i am now using my philips php-19x (aka proview 900w/Mag LT916s Model 900p/ Xerox) and yes turn on the monitor 2 seconds screen goes black and the blue power light stay lit, but if you shine a torch onto the screen you can see the lcd display is working, and if you turn the power off and on the cycle starts again, like most of us we checked the web to no avail, untill yesterday. I have been playing with this monitor for 3 months on and off after a kind fellow gave me this monitor for free on uk freecycle and of course i checked all the caps on the psu/inverter pcb and more components all seemed fine checked the ccfl lamps by taking them out of the lcd panel (15 minutes to dismantle) both lamps where fine not orange, a nice bright light, and knowing that if the monitor started woking ok and the back lights did not fail it would run like this for ever until you turned the monitor off / video blanking so i was convinced that there was no fault with the psu/inverter board, and as i stated i found the solution at last (yeh) and here it is many that's to all on the bad caps forum and of course the main man -----barry wilkins-----
Re: Mag LT916s Model 900p 19" LCD dropping like flies
I have got to the bottom of this ,after I got one of scopes out (PM 97) the output of the TL 494 IC was disappearing .The IC seems to crash easily ,I think the oscillator on pins 5&6 actually stops.
I cleaned the whole board with an aerosol of PCB cleaner and heated up the PCB up with a small craft heat gun to quite hot .
I fitted a 0.01 mfd capacitor across the IC pins 12 to 7 to decouple the VSS supply ,because I felt the cause of the IC stopping could be interference based
The monitor now runs for all day with no sign of the backlights cutting out.
I found out this LCD display was made by proview.

Any monitor will work with any computer provided the correct graphics card driver is installed. When you install Vista and you do not install the graphics driver, Windows will default to Generic VGA driver and you will not get the best resolution that the monitor can display.
