I had the same problem with my machine. Since my machine stays on 
almost all the time it did bother me to much.. When I would 
rearrange my radio/computer room and shut the system down, I would have
to power cycle a couple of times to get the picture in straight.
To solve the problem is easy... All you need to do is take out
two screws on the back on the monitor case. 
NOTE: TURN OFF THE POWER BEFORE TAKING THE CASE OFF.. lots of 
hungry little volts running around in the monitor...
YOu will find 4 or 5 variable resistors, little flat wheels
mounted on the very back of the monitor.
note the position of each pot. NOw rotate the pot a full turn each direction
and return it to its orginal position. repeate for each pot..
put the case back on and your problem should have gone away.
