HP Pavilion f70 monitor has dislodged on/off button
The on/off button for my monitor has become dislodged and now I can't turn the monitor off, unless I remove the power cord from the wall. I think the solution is to open the monitor so that I can lift off the face cover of the monitor and re-attach the on/off button.
I have looked at HP's website and they don't offer any diagrams/ instructions on how to do this. Can you help me?
Thanks in advance,

Nor would they.
If you cannot see how to open it up then U suggest the item is a snap together shell and best left alone. If it is on all the time and the wall plug inconvenient- cut the power cord[unplugged of course] and insert an inline light switch- some times called a torpedo switch.
Any electrical store will have them.

Verify that it's the monitor and not the computer by hooking another monitor to the computer and observing the results. If it's your Hp f70 that is the problem, then something in it is going out, like the inverter or perhaps a loose connection. If you don't want to open the monitor and have a look-see for yourself you can always take it to a shop to have it checked out.
12 VDC , 4.16 A (4,16 A)
Frequency: 50/60 Hz
Power Consumption: less than
36 W in operating mode.
I think the other two pins are not used. It just requires the 12 Volts DC. +ve and -ve, positive and negative, respectively.
Unless I have the model number wrong (F1903), this monitor was relased in 2004. If it is 8 months old then it should be fixed under warranty. This can be bad problem in the bcaklight inverter circuits or bad lamps due to bad soldering works, bad power supply, please look here to see hwat is involved in repairing the monitors: http://s807.photobucket.com/home/budm/allalbums
plumldk1, Watch some video clips of "LCD monitor disassembly" at youtube. Yes, parting the rear cover from the front plastic bezel is the hardest thing to do!!!! Also visit www.ccl-la.com/badcaps.htm. You might see some tricks to help get the thing apart. Are you positively certain that it's the "backlight" and not the "electronic ballast" that has failed? Will you find any swollen electrolytic filter capacitors on the SMPS board? 12fixlouie
The symptoms you describe, pretty much diagnose a failed High Voltage power supply board problem in the monitor. This is usually cost prohibitive to repair, as LCD monitor prices have dropped a bit, so your monitor is beyond economical repair.
Open your monitor back up and look for unplugged connectors, especially the one to the back of the LCD. I had this same problem with a HP F1703. The owner whacked it so hard when the backlight stopped that they dislodged the connector.
