When the monitor fires up it takes 10-15 minutes to stabilize the desk top , the video card has been re-seated in the computer and connection has been re established, when I disconnect the DVI cable the floating color bars are equally unstable and has Vertical hold issues until the DVI is reconnected and it re-stabilizes as above. I was thinking of opening up the monitor to reconnect all of the cables incase of intermittent connections.I am looking for a service manual to open the cassing. Please and thank you Paris

You wont find a service manual for the monito..
1.) Take the unit off its pedastall and remove the 4 screws holding the back support bracket on

2.) The front bezzel seperates by having to pry the two halvs appart at the parting line. Using a small screw driver at the bottom middle start to releasing the catches that are spaced about 1" from each other. Go slow dont force it!!!!!!! Remember the clasps holding the two halves together are spaced 1" apart once you find it the first one you will be able to pop the rest allone the bezzels edge.

3.) once the bezzel s off the unit seperates.

4.) there arnt many connections inside but it doesent hurt to check.
